1 FRAMO DOCUMENTATION

The Framo documentation consists of instructions and drawings for installation, operation and

service. This documentation is our property. It is not to be traced, copied or published without our

written consent, nor to be misused in any way.

Framo Mounting Instruction is the general requirements to the yards for handling and installation

of a Framo cargo pumping system, and it contains general instructions for handling, storage and

installation of Framo equipment, in addition to design and installation of the hydraulic piping

system.

It is based upon practical experience from installation of high pressure hydraulic systems in co-

operation with yards and owners all over the world. Kindly follow the instructions carefully to ensure

a successful installation and a well functioning cargo pumping system. Please make special

attention to the following:

Think safety during design:- Appropriate location of equipment.

- Sufficient service space.

- Appropriate lifting equipment for maintenance and repair of installed equipment.

- Appropriate marking of noisy areas.

Think safety during installation:- Use of correct and approved lifting equipment.

- Be aware of foreign voltage from interfaced equipment and switch off the main

switch before any work on electrical equipment.

- Hydraulic oil (on mineral oil base) has a flash point between 180-230°C,

and any leakage must not come in contact with heated surfaces.- Hydraulic pipe connections, flanges, valves etc. must not be located above

or close to heated surfaces.

Think cleanliness during installation:- Maintain a high standard of cleanliness at all times.

- Keep pipes and components clean and protected during the whole production- and

installation period.

Others:

- Do not paint mechanical parts of switches (valve shutdown switches, or equal), manometers,level gauges or similar equipment, or flexible rubber elements (flexible hoses, dampers etc.)

- Never weld on Framo equipment without special agreement.

The instructions are also based upon the authorities' requirements. These are however revised

from time to time, and it is therefore necessary to keep oneself informed about the alterations and

discrepancies between the different national authorities and classification societies.

If drawings are sent to Framo for information or comments, yard must call attention to eventual

deviation from Framo Mounting Instruction by giving remarks on the drawings.

Page 2 of 8

The Framo hydraulic system is designed as a central hydraulic ring line system. The hydraulic

power unit delivers oil to the main pressure line, and from this line it is possible to run a number

of hydraulic motors as long as the oil delivery is sufficient. In order to control the speed of themotor and to prevent over-speed, a control valve is fitted for each motor.

For most of the systems delivered today, the hydraulic power packs, system tank, oil cooler and

main filter are assembled, tested and supplied from our factory as complete compact power units.

5 LOCATION OF OTHER EQUIPMENT

- Hydraulic driven pumps on deck, see section 7.

- Hydraulic driven thruster motor, see section 11.

- Deck mounted cargo heat exchangers, see section 12.- Submerged cargo heat exchangers, see section 13.

7 HYDRAULIC POWER UNIT (HPU)

Location of the hydraulic power unit (HPU) must be considered in an early stage of the ships

planning, and one has to take into consideration:

- Minimum noise level in accommodation area

- Minimum noise emitted from the ship

- Optimum pipe routing

- Easy access for maintenance

Generally, HPU room location is recommended as shown below.

For further information, see section 8.

6 FRAMO CONTROL SYSTEM

The Framo cargo pumping system is normally operated/monitored from the Framo control panel,

consisting of hydraulic system control panel and cargo pump control panel.

The control panel should be installed in the cargo control room or other indoor location where living

quarter conditions can be kept. It should also be sufficiently illuminated and arranged for good

contact/communication to the cargo manifold area to ensure a proper and safe cargo handling.

The panels are sometimes designed for installation in yards console, but the above recommenda-tions still apply.

The control system may also be interfaced with, and operated from vessels integrated control system.

Local panels / motor starters should be installed in the vicinity of the controlled equipment.

Emergency stop arrangement

Framo supplies three emergency stop buttons as standard. One to be located close to the power

pack room, and two for location on deck, normally installed close to manifold.

8 HYDRAULIC TRANSMISSION EQUIPMENT

Location of electrical equipment shall comply with degree of protection by enclosure (IP).

Electrically operated hydraulic control valves supplied by Framo must be installed in safe area:

- Electrical/hydraulical remote control assembly for the hydraulically driven pumps, controlling

the pump speed, (normally installed on main deck level).

- Thruster pilot control valve assembly, must be installed as close to the thruster motor

as possible. For more details, see section 11.

Separately supplied pilot filter for these valves must be located as close to the valves as possible.

9 HYDRAULIC OIL STORAGE / CLEAN OIL DRAIN TANK

The hydraulic oil storage / clean oil drain tank incl. necessary equipment is yard supply.

Design requirements are described in section 10.

Framo recommend to install the storage/clean oil drain tank below the HPU, either as two sepa-

rated tanks, or as a combination tank for storage- and clean oil drain. With this location, eventual

overflow from the system tank and drainage from the HPU will gravitate down to the clean oil

drain tank.

The storage tank/clean oil drain tank must be installed in-door, and the ship bulkhead or shell

plating must not be part of the tank. This to avoid condensation and water in the hydraulic oil due

to temperature differences. Neither must heated surfaces with temperature above 60°C be part of

the tank, (fuel tanks etc.).

The transfer unit must be located close to the storage/clean oil drain tank to minimise the suction

side pressure drop.

1 GOODS RECEIVAL

Immediately after receipt of equipment, please check that the supply corresponds to the packing

list. Any missing items must be reported to Frank Mohn Fusa AS without delay.

The equipment should be carefully inspected for transportation damage. Damages should be

recorded, photographed, witnessed and reported to carriers and to Frank Mohn Fusa AS.

2 PRESERVATION, PACKING AND MARKING

Preservation

Stainless steel components are pickled, cleaned and ready for installation.

Mild steel components are protected against corrosion by means of priming or painting outside andprotecting oil inside. The preserving oil is mixable with the hydraulic oil, and will give sufficient

protection for about 1 year provided that the blank flanges are kept on.

Un-primed mild steel seal faces are normally protected by a removable corrosion preventive

coating (Tectyl).

Packing and marking

Generally most of the Framo components are packed in plastic-covered wooden boxes.

Electrical equipment

like electrical cabinets, starters and control panels have also silica gel inside for protection againstmoisture. Ventilation openings and cable entrances on electrical motors are in addition covered by

fire resistant tarpaulin.

Power units

are normally covered by plastics and shipped in containers. If they are shipped on open flat racks,

they are covered by light tarpaulin (reinforced plastic) in addition to the plastics.

Submerged cargo- and ballast pumps

are supported by special wooden racks. If the length is more than 14 meters they are split in two

sections to simplify handling and transport.

Smaller pump units, deck trunks etc.

are fastened on pallets and covered by plastics.

The deck trunks seal faces are protected by plywood.

Prefabricated pipes

are packed on transport racks with wooden frames and covered by plastics.

3 HANDLING OF FRAMO EQUIPMENT

Even if the components used in Framo Cargo Pumping Systems are of rigid construction, they

should always be handled with care. Never step or climb on the equipment.

Be careful not to destroy or remove the transport protection before final installation onboard.Lifting, lowering and handling in general should be done slowly and carefully to avoid damage to

motor bearings caused by vibration and shocks.

Note! Handling information given on the package must be strictly followed.

Stainless steel components must not be in direct contact with mild steel.

3.1 Handling of power units

General info

The power units are equipped with 4 lifting lugs. All of them must be used when lifting. Normally, a

lifting device with 4 slings of equal length can be used to lift the power unit. Avoid contact between

exposed parts of the power unit and the lifting slings.

If special lifting tools are required, these are supplied by Framo together with the power unit.

Note! Forklift must never be used to lift the power unit.

Transportation in container

Normally the power units are shipped in closed containers and should be taken out of the container

as shown for the cargo pumps on page 6.If the power units are shipped in containers with open top, please note that these containers have a

narrow passage at the top. Therefore, the power units must be lifted free for easy guiding and

taken out broadwise. Special care must be taken not to collide with the side walls of the container.

Fig. 1

Transportation on flat rack

If the power unit is wider than the container width, it is transported on a flat rack with a special cage

for protection. This cage must be removed before the power unit can be lifted off the flat rack.





No.1401-0003-4

Feb-2000

Page 5 of 9

3.2 Handling of submerged cargo- and ballast pumps

The pumps are designed to withstand flexing and bending of the vessel’s structural members

(bulkheads etc.). For this reason the pump bend easily, but as long as this bending is well within the

elastic limits, it will do no harm to the pump. Incorrect and careless handling might, however, put

undue strain on the pumps, causing permanent damage.

The only acceptable way to lift pumps out of the wooden racks is to lift each pump/pump section

separately.

The pumps shall under no circumstances be lifted like this:

Note! Damage to pump due to incorrect lifting and handling will not be covered by Framo’sguarantee.

Fig. 2

Fig. 3





No.1401-0003-4

Feb-2000

Page 6 of 9

If the pumps have been shipped in a closed container, they have to be pulled out as shown below.

The following equipment is necessary for unpacking and lifting (Framo supply):

- Two softslings. Minimum working Load Limit (WLL): 5 000kg. Length: 18 meters

- Four softslings. Minimum working Load Limit (WLL): 1 000kg. Length: 2 meters

1. Four pallets in a good condition (yard supply) to be placed as shown in fig. 4 - 6.

2. The two softslings (L = 18m) must be fastened on the horizontal beam of the transportation

frame and to a forklift.

To pull the transportation frame out of the container the forklift must have a constant tension on

the softslings. Pull load is approximately 60% of transportation frame and pumps weight.

3. The other two pallets must be placed as shown in fig. 6. They must not interfere with the lifting

points.

4 STORAGE AT YARD

Generally it is preferred that all Framo equipment should be stored in-door.

The equipment must be stored away from corrosive or chemically damaging fumes.Storage even for a short period in an area where work activities such as welding, grinding, sand-

blasting, painting, etc. is going on is prohibited.

For protection and easy identification, keep the equipment in the packages supplied from Framo

until installation onboard. If only some items in a box are needed for installation, keep the others in

the box until installation.

Blank flanges must not be removed before final installation.

The protection on electric motors must be kept on until start up, and will then be removed by the

Framo commissioning engineer.

Control panels must be covered after installation onboard.

As informed in chapter 2, Framo equipment is preserved for 1 year storage. This includes also

cargo- and ballast pumps due to the internal mild steel hydraulic motor and high pressure pipe.

Note! For long time storage (1 year or more), contact Framo for special instruction.

The minimum storage conditions for Framo equipment are given below.

4.1 Storage in dry and clean conditions

All electrical components must be stored in a dry, clean room where temperature is kept steadyabove dew point. Typical components are:

- Electrical control panels

- Main electric boxes

- Starters

- Electrically driven power units *

* Electrically driven power units may be stored in warehouse without steady temperature provided

that the electric motor heating elements are connected and switched “on”.

Note! Connecting power voltage to termistors will damage the termistors and eventually the

motor windings.

Warnings should be placed on the motors when the heaters are connected.

4.2 Warehouse storage

The following must be stored in a dry, clean warehouse:

- Diesel driven power units.

- Hydraulically driven components.

- All valves and fittings for the hydraulic system.

- Deck trunks in mild steel.- Portable cargo pump.

- Flexible hoses.

- Mild steel pipes.





No.1401-0003-4

Feb-2000

4.3 Outdoor storage

Following equipment may be stored outdoor, provided it is properly protected with tarpaulin to protect

it from iron dust from grinding, welding spatter, sea water spray, sand and bird droppings.

(Stainless steel may corrode if surface is polluted)

- Cargo coolers/heaters.

- Deck trunks in stainless steel, (flange protection must be kept on).

- Pump supports.

- Stainless steel pipes.

- Submerged cargo pumps and ballast pumps.

Submerged cargo pumps and ballast pumps

must be stored with their axis in a horizontal position, preferably in the same wooden rack as they

were received. If the pumps have to be removed from the rack, they should be supported in at least

three points as shown below.

Note! The pumps must not be in direct contact with mild steel.

Tarpaulin

Oil in drums.

To prevent water from leaking into the hydraulic oil, the drums have to be stored horizontally and

in such a way that the drum bungs are wet by the oil.

The hydraulic oil is mixed with special additives, which improve the oil quality. If the oil is mixed

with water, the additives may lose effect, or in worst case, give negative effect. Corrosion will

occur and abnormal wear will lead to breakdown of the system.

3 INSTALLATION OF DECK TRUNK AND BRACKETS FOR INTERMEDIATE

AND BOTTOM SUPPORT

Prior to pump installation the deck trunk and brackets for intermediate and bottom support have to

be welded into the tank. Use of Framo dummy gives a correct installation of deck trunk, bottomsupport brackets and bracket(s) for intermediate support.

The following installation procedure is based upon use of Framo dummy.

3.1 Framo dummy

The dummy has brackets for all flanged pipe connections on the pumps top plate for adjustment

and prefabrication.

It is neccessary to remove the flange protection for deck trunk (plywood) when using

the top plate dummy. It is important to remount the plywood after use of dummy.

The dummy equipment package and assembling of measuring pipe are shown on fig. 8a and 8b.

For length of dummy (LD), see Framo specification.

3.5 Recommendations for welding stainless steel to carbon steel

Sometimes it becomes necessary to weld stainless steel to carbon or low alloyed steel. A typical

example is stainless steel wells welded into carbon steel tanks.

The dilution of the weld metal by the base material must then be considered to avoid the formation

of hard brittle structures.This is done by using a welding consumable with different composition to both base materials.

Carbon steel filler metal will result in a high alloyed martensitic microstructure on the stainless steel

side of the weld. Filler metal of the same composition as the stainless steel will result in the same

microstructure on the carbon steel side. This microstructure will result in extensive cracking, often

very difficult to observe.

The correct filler metal shall instead be overalloyed stainless steel or Ni-based alloys to secure a

ductile weld metal. These filler metals will tolerate a substantial dilution from the carbon steel

without hardening.

The composition should be specially balanced to ensure that the total alloy content is adequate to

accommodate dilution effects and which have a ferrite content sufficient to provide high resistance

to hot cracking.Preheating shall not be performed on austenitic stainless steel, since this will promote carbide

precipitation in the grain boundaries and the formation of sigma-phase (a hard and brittle phase

that dramatically increases the risk of cracking).

4 PREFABRICATION OF DECK PIPING

When the trunk is installed, the top plate dummy can be used for adjustment/prefabrication of the

piping.

- Remove the laser from the top plate dummy.

- Assemble the brackets for the current connections.

- Bolt the top plate dummy to the trunk in correct position (see dimensional drawing for top plate).

The dummy can now be used for adjustment of the piping by fixing the pipe flanges to the relevant

positions/brackets on the dummy.

Hydraulic piping

Connections for

other pipesCargo pipe

Be careful not to damage the sealing surface on the deck trunk and

protect the seal faces by the supplied plywood after this operation.

5 ASSEMBLING OF PIPE STACKS

The pump is to be assembled in a horizontal position. Every pump part is to be supported in at least

two points.Note! The pumps must not be in contact with carbon steel.

Check that pump no. on all the pump parts are identical. Pump no. is placed on top plate and

flange for volute casing. Locate the pump parts in correct positions one after another.

6 INSTALLATION OF PUMPS IN TANK

The Framo cargo pumps have two different resilient arrangements on top plate. Installation of each

arrangement is described separately.

Preparations:

Welding, sandblasting and grinding must be finished and tank must be

properly cleaned before installation of pump in tank.

For carbon steel tanks, also coating must be finished before installation.

Pickling

Pickling will be required prior to installation if the pump has been exposed to iron dust during

storage or corroded surfaces/spots are detected. Framo recommend Avesta Pickling Paste or

equal types for stainless steel.Follow the manufacturers procedure for pickling before starting the work.

Blank flanges

Blank flanges and seals on top plate shall be left until connection of the pump to the vessels piping

systems. The blank flanges on the pumps suction opening and the protection around the pump

shaft shall be removed only by the Framo service engineer before water is filled into the tank.

Transport securing (Only on pumps with vacuum stripping pipe)

The steel wire on lower vacuum stripping pipe shall also be removed by the Framo service engineer.

Special tools required for installations are supplied by Framo in the toolbox.

See tool list for descriptions.

7 PUMP WITH COFFERDAM HEADER TANK

Permanent liquid filled cofferdam is used when the submerged cargo pump is handling only one

type of cargo (oil production & storage vessels).

Filling of cofferdam

- Fill the cofferdam through the headertank until the

liquid level stabilises just above low level mark on

the sight glass.

- Use a ISO VG10 hydraulic oil in the cofferdam.

(DIN51524 (1) HL, for instance Shell Morlina Oil 10).

Due to expansion and air in the system, the level will

stabilize between 2 to 7 days after filling.

- The cofferdam volume depends on pump size and

pump length. The following formulas give approx.

1 STORING ON BOARD

The portable pumping equipment must be stored easy accessible

in a clean and dry area.

The concentric hose can be stored on brackets on the bulkhead

(see fig.1), or on a suitable hose reel, or lying in a shelf.

The cargo hose and extension hoses can be stored on a suitable

hose reel, or lying in a shelf.

The pump and hoses must always be safely supported and

fastened in order to avoid wear or damages due to ship

movements. It is especially important that the hoses are not

hanging or laying over sharp edges, or that sharp objects are

placed upon them.

The bending radius for the hoses during storage must be

according to dimensioning drawings.

For TK150 / TK6 control valve + snap-on couplings are delivered in

an equipment box. For TK80 control valve is connected to pump,

while snap-on couplings are delivered in an equipment box.

Equipment boxes are delivered with bracket for installation in fixed

location together with the portable pump.

h = sufficient height above ship deck to avoid exceeding the

allowable bending radius of the extension hoses, and giveeasy access for connection of the extension hoses.

2 COUPLING STATIONS FOR PORTABLE EQUIPMENT

The portable pump includes hydraulic hoses with a control valve either connected to the end of the

hose(concentric hose) or separately delivered. Standard length of this hoses are 10 and 18 m.

Separate extension hoses must be connected between the control valve and the coupling stations

(standard length of extension hoses is 10 and 18 m).

The hydraulic ring line must be equiped with coupling stations (pressure and return) for connection/

operation of the portable pump.

Each coupling station consist of a ball valve with blind flange for pressure connection, and a non-

return valve with blind flange for return connection. Snap-on couplings are delivered separately in

an equipment box, and are only mounted by ship crew when pump is connected for use.

The number and location of coupling stations must be selected so that the portable pump can be

used in every tank.

A coupling station should preferably also be located close to the pump storage, to simplify testing of

pump.

Installation of coupling stations in hydraulic ring line must be according to figures below. This to

avoid extra bending forces from the extension hoses on the coupling stations.

4 EXAMPLE OF PUMP INSTALLATION WITH FRAMO DUMMY

The pump casing has to be placed in the section before it is closed. It is of importance that the pump

casing is protective covered until the installation of pump in tank. Prior to pump installation, the deck

trunk and brackets for pump supports have to be welded into the tank. Use of Framo dummy will helpyou to get a successful installation of deck trunk and bracket of intermediate supports.

The following installation procedure is based upon use of Framo dummy.

4.1 Framo dummy

Note! It is necessary to remove the flange protection for deck trunk when using

the top plate dummy. It is important to remount the protection after use of dummy.

The “dummy equipment package” is shown on fig. 12.

6.1 Additional information for pumpsassembled during installation in tank

Note !

The pump has to be pressure tested after assembling and

installation in tank. This requires an arrangement in tank

which gives access to the flange connections in pipe stack.

Lower the lower part of the pump until the top is approx.

0.5 m from deck trunk.

Install the installation tool on the deck trunk (see actual tool

drawing).

Continue lowering until the pump’s lower part is resting on

the tool. Secure the lower part before removing the lifting

tool.

Clean all o-ring grooves with a dry rag, and assemble parts

shown in fig. 22.

Before lifting upper part of the pump, assemble guiding

bolts on top plate (see fig. 32a).

Lift the upper part of the pump in position above deck

trunk. Remove blank flanges and clean the flange

connections with a dry rag. The gasket between top plate

and deck trunk must be placed upon the deck trunk.

Continue the lowering until the distance between the

flanges is 50-100 mm. Install lifting bolts (toolbox) and lift

the lower part by using the lifting bolts. Be careful when the

connection pipe enters the high pressure pipe.

The cofferdam volume depends on pump type and pump length. The following formulas give

approx. volume (in litres) required to fill cofferdam to low level mark in header tank:

All the SB-pumps have liquid filled cofferdam.

- Cofferdam liquid:

Ethylene glycol or propylene glycol* : 50-60 %

Use pure glycol without additives.

Commercially available automotive anti-freeze

should never be used. Some of the additives in

anti-freeze tend to form deposits on seal parts

and thereby causing failure on the seals.

Corrosion inhibitor : 0.9%

(Rocor NB Liquid or equal) (initial dosing)

Other types of corrosion inhibitors for cooling

water systems can also be used. The corrosion

inhibitor must be compatible with glycol. The mix

ratio and the use of the corrosion inhibitor must

be according to the suppliers data sheets, as

this can vary for the different types available.

Demineralised water: 40-50%

Freezing point ~ - 35°C v. 50% glycol

Freezing point < - 40°C v. 60% glycol

Volumetric

expansion : 0 - 60°C ~ 63.5 x 10-5 litre/litre°C

Filling:

- Install the drain tool and unscrew the drain plug.

Connect a hose to the drain tool. It is then

possible to fill the cofferdam through the hose

while venting at the header tank.

Fill the cofferdam until liquid level stabilises at

max. level mark on the sight glass.

- Water/glycol to be filled after filling of

hydraulic oil.

1 GENERAL

The hydraulic power unit (HPU) delivers oil to the main pressure line and consists of the following

main parts:

Fig. 1 Hydraulic power unit (HPU) with 2 diesel driven and

2 electric driven hydraulic power packs.

Normally the hydraulic power units are supplied as shown in fig. 1, but they may also be

delivered with the auxiliary unit as a separate item or with the auxiliary unit, power packs and

filter/cooler unit delivered separately.

- Electric driven hydraulic

power packs

- Diesel driven hydraulic power

packs

- Main hydraulic oil filter

- Hydraulic oil cooler

- Common foundation

- Enclosure for separating high

pressure hydraulic oil from

hot surfaces.

A hydraulic power pack consists

of a hydraulic pump with a built

on pulsation damper, either

driven by an electric motor or a

diesel engine. Each hydraulic

power pack is resilient mounted

and exhaust, fuel and water

connections are delivered with

flexible connections.

The auxiliary hydraulic unit

consists of a hydraulic system

tank and electric driven feed

power packs.





No.1401-0034-4

Rev.B Jan2003

Page 3 of 14

2 ARRANGEMENT

Normally the HPU is located at the same deck as the auxiliary unit with the hydraulic pumps facing

forward and with the motor shafts parallel to ship centre line. The shield must be extended to the

next deck. All hydraulic piping from HPU to consumers on deck will then be in the hydraulic roomand diesel engines/electric motors will be located in the engine room.

Fig. 3 Auxiliary unit located above the hydraulic power unit

The auxiliary unit is normally a part of the

power unit. If it is delivered as a separate

item it may be oriented in any directions but

should if possible be located on the same

deck as the hydraulic power unit.

If not possible it should be located on ahigher deck level but not more than

8 meters above the hydraulic

power unit. This is limited

by the maximum allowable

drain oil pressure.

Fig. 2 Recommended HPU room arrangement

Fig. 2 and 3 shows an arrangement which gives:

- Minimum noise level in accommodation area

- Minimum noise emitted from the ship

- Easy access for maintenance

- Optimum routing of hydraulic and exhaust pipes.

- Shielding of high pressure hydraulic oil from engines/hot surfaces

and electric equipment (Shield to be extended as shown in fig. 12.)

- Machinery room ventilation can be used for the

electric motors/diesel engines.

Note! High pressure piping/flanges to be segregated

from ignition sources (exhaust, electric starters, etc.)

4 VENTILATION AND HEAT DISSIPATION

It is important that the power unit gets sufficient air supply according to motor size and number of

motors. Yard is responsible for:

- Sufficient ventilation capacity

- Correct direction of air flow

- Acceptable air temperature

- Clean and water free air

CapacityCalculation of necessary ventilation capacity is yard responsibility, but approximate air consumption

is given in fig. 7. For calculation of radiated heat see technical data.

This curve is based on temp. increase ∆T = 10°C.

Fig. 6 Space for lifting

Lifting arrangement

Lifting arrangement is yard responsibility and must be installed above each power pack and the

hydraulic oil cooler. Monorail is recommended above the diesel engines and electric motors.

Approximately weights of the major components:

Electric motor: 2000 kg Hydraulic pump (single): 400 kg

Diesel engine: 2500 kg Hydraulic oil cooler: 1400 kg

Example: 3 x Diesel engines à 400 kW Total 1200 kW : 9 m3/s

Alternative location of venting duct for correct air flow:

Air distribution

The air should be distributed to all parts of the room to avoid pockets of stagnant hot air and any oil

vapour from crankcase ventilation.

Arrangement for separating the hydraulic side from motor side with ventilation ducts on both side is

shown fig.8. When arranged like this, the ventilation capacity for the hydraulic room will be reduced.

Noise reduction

To avoid noise transmission to surrounding areas, some basic requirements to the power unit room

must be fulfilled if the HPU is installed in critical interface area. Key items are:

- Hydraulic room (with entrance of double door type).

- Noise trap on in- and outlet of ventilation in order to achieve effective absorption of high

frequency noise.

- Flexible and air tight penetrations for pipes and cables.

- Critical interface areas such as bulkheads against accommodation areas should be covered

completely by noise absorbing material. Ref. fig. 11.

Auxiliary unit (if delivered separately)To prevent vibrations transmitting to the steel structure, the auxiliary unit must be mounted on rigid

foundation filled with concrete (minimum 70 mm thickness).

Auxiliary unit is resilient mounted as shown in the figure 13. Flat bars and rubber insulation aresupplied by Framo. For welding of flat bars to the foundation use the following procedure:

- Place the auxiliary unit with flat bars and rubber insulation on the concrete filled foundation.

- Spot weld the flat bars to the foundation (careful with the rubber insulation).

- Remove the auxiliary unit and the rubber insulation before the flat bars are welded to the

foundation with continuous fillet welding.

- Assemble the auxiliary unit after cleaning and painting of welding zone.

6 COOLING ARRANGEMENT

The hydraulic oil is cooled by sea water or fresh water automatically controlled by an electrically

operated on-off valve. The valve is operated from the Framo PLC (Programmable Logic Control).

The cooling water flow and max. pressure must be in accordance with the technical data given for

the system.

Note! - Too low water flow through the cooler may cause corrosion/fouling problems.

- Too high flow may cause erosion problems.

The water flow is controlled by means of orifices at the water inlet and outlet side of the hydraulic

oil cooler. This orifice is calculated and delivered by Framo. To verify that the flow is correct,

differential pressure between the two test points must be measured. If differential pressure is out of

the tolerances given in technical data, Framo must be contacted.

When the power unit is installed above sea water level and sea water is used as cooling medium,

piping at the outlet side must be routed above oil cooler and a vacuum breaker must be installed.

Sea water piping should have sufficient zinc anodes.

7 CABLE/STARTER CABINET FOR ELECTRIC EQUIPMENT

Recommended cable routing:

Fig. 15

The hydraulic power packs are resilient mounted and therefore allowed to move relatively to the

foundation. Accordingly, cable trays and their supports must be connected to the foundation and not

to the hydraulic power packs. Welding on electric motors are prohibited.

The cables should be arranged to allow for removal of electric motors.

The starter cabinet should be located outside the hydraulic room (ref. fig.8).

Wiring between hydraulic power unit and local diesel engine control panel

To secure optimal performance and running conditions of the diesel engine, following details must

be noted (ref. fig. 8):

- Individual screened cables to be used for pick-up and actuator.

- The screens to be terminated to dedicated terminals, not to ground.

- Max. cable length and min. cross section to be respected.

8 STARTING SYSTEM FOR DIESEL ENGINES

Air startingThe piping from the reduction valves to the

starter shall be as short as possible in order

to limit pipe losses. Starter motor is supplied

with a flexible hose.

All connections should be made up with

Loctite pipe sealant or equivalent.

Teflon tape should not be used in starting air

systems.

Design the piping to ensure that drain does

not enter the starter motor. Install a drain

valve at lowest point (see fig.16).

Exhaust pipes from several engines shall have separate outlets. The exhaust piping should not be routedat the hydraulic side of the shield. It must be routed in order to prevent entrance of water (ref. fig. 20).

Fig. 21

Note! Installation, supporting and calculation data for the exhaust piping are given in separate

instruction from the engine makers instructions.

Note! The exhaust system must be shielded .

The diesel engines are provided with a compensator at

the outlet of the turbocharger to prevent excessive

stress to engine.

The compensator for exhaust pipe allows a maximum

simultaneous lateral movement of ±10 mm and an axial

movement of ± 10 mm (ref. fig.21).

A combined silencer/spark arrestor is provided for each

engine as a separate item.

Keep the blank flange at the top of the exhaust

compensator on until initial start-up to be sure there is

no water ingress.

Fig. 20

Install the silencer as close as possible to the engine or near the outlet.

The silencer can be installed in any position from horizontal to vertical, however flow direction

indicated on the identification plate must be respected. When mounted horizontally note that the

soot collector must be at the lowest point enabling for periodically cleaning.

3 ELECTRIC MOTORS

Refer to instruction “Installation of power unit” for recommendations regarding routing of power

cables, cable trays and supports. Yard must ensure that grounding of all motors and related

equipment is carried out.

Power pack motors are heavy consumers on board. Yard is responsible for dimensioning the power

cables with respect to thermal capacity and voltage drop during starting and full load operation.

If applicable, interface to power management system is normally implemented in power pack

starters. If starters are supplied by Framo, a power management system functional description

detailing quantity of signals, pulsed or maintained contacts etc. to be submitted. If applicable, by

pass switch shall be provided by yard.

Nuts for power cable termination points must be secured with lock nuts and tightened with torque

meter according to type of bolts/thread dimension used. This is also applicable to termination points

in starters and feeder panel.

In order to preserve original protection grade (IP), correct glands or sleeves must be used.

Refer to applicable documentation for details regarding starting methods and wiring diagrams.

Notes! Bolts, nuts, washers etc. must not be dropped into the motor as such foreign

particles will lead to short circuit of the motor.

Cables for motor-heating element and thermistors must not be interchanged,

as a voltage higher than 2.5 V will damage the thermistors.

Motor heating elements must be powered immediately after installation on board.

2.1 Power pack starter

- The thermistor amplifiers (one per power pack motor) must be installed in starters and

connected to the thermistors in the motor. Thermistor amplifiers shall trip the motor if activated.

(The amplifiers are delivered as loose items if starters are supplied by Yard).

- The running signal to control panel is also used for unloading the hydraulic pumps duringstarting. The running signal must be given as soon as start is initiated and shall be maintained

as long as the motor is running. Refer to sketches below:

In order to obtain correct direction of rotation (counter clockwise), connect phases according toapplicable diagram.

- Due to size/weight of contactors, they must be installed on a rigid/stiffened plate to avoid

vibration interference during making and breaking.

- Arrangement for space heaters to be provided.

- Ratio of current transformer to be informed to Framo if amperemeter is required on ‘Hydraulic

System Control Panel’.

2.2 Feed pump starter (closed loop system only)

The feed pumps should be fed from different power supply sources if possible. This will increase

availability as one feed pump shall always run. Arrangement for space heaters to be provided.

1 GENERAL

In general we have the same requirements for installation of yard equipment connected to the

Framo system, as for equipment supplied by Framo.

The equipment must fit in with the Framo system regarding:

- Cleanliness

- Oil type and viscosity

- Hydraulic oil consumption and pressures

- Functioning without giving pressure peaks in the hydraulic system

Hydraulic system pressure, return pressure and other information are given on the Framo hydraulic

diagrams.

Equipment and connecting pipes must be properly cleaned prior to commissioning.

Oil used for flushing, testing and preservation must be compatible with the oils meeting Framo

requirements.

Note! Never use engine oil for combustion- or engine lubrication oil in combination with hydraulic

oil or its equipment, as this will damage the hydraulic oil.

2 HYDRAULIC OIL STORAGE / CLEAN OIL DRAIN TANK

The storage/clean oil drain tank incl. necessary equipment is yard supply, and shall in addition to

storage of oil make it possible to drain off clean oil from the system during service.

To avoid water mixing with the oil and simplify drainage of water, it is recommended to slope thetank bottom down towards the bottom drain outlet. If the tank bottom is not sloped, the suction

outlet to hydraulic oil transfer pump must be minimum 100 mm above bottom drain outlet.

Hydraulic oil tanks must be vented indoor, not to open deck. Air filters should be used.

All pipes (except overflow) must have outlet openings below minimum oil level.

Fig. 1 Hydraulic oil storage tank and clean oil drain tank

No.1401-0010-4

Rev.B Nov-2002

Page 3 of 4

3 CLOSING TIME FOR CARGO VALVES

To prevent cargo pump over-speed and surge pressure in the cargo system, the cargo valves

must not operate faster than stated below without Framo approval.

Generally we recommend cargo- and drop line valves to be remotely operated. Manual operated

valves is recommended to have gear.

Cargo pump type Cargo pipe diameter (mm)

Minimum opening time(seconds)

Minimum closing time(seconds)

SD100-SD125-SD150 100 – 150 15 15

SD150-SD200 151 – 200 20 20

SD200-SD250 201 – 250 25 25

SD300-SD350 251 – 400 30 30

SD350 > 400 30 30

Storage volume depends on the ships operating trade area (easy or difficult supply of hydraulic oil)

and owner’s experience.

To be prepared for all possibility, we recommend the storeage volume to be approximately

30% of total oil volume in the system.

Minimum clean oil drain volume must be sufficient for draining of hydraulic pressure- and return

lines on deck and down to the power unit in addition to the power unit/auxiliary unit itself.

Recommended clean oil drain volume to be approximately 70% of total oil volume in the hydraulic

system.

The storage/clean oil drain tank may be used as two separated tanks or as a combination tank.

The storage/clean oil drain tank and its piping are parts of the hydraulic system with the same

requirements regarding cleaning as the system.

Tanks in mild steel must be degreased and grit- or sandblasted internally to SA 2.5 and given two

coats of a two-pack epoxy based cargo tank coating (resistant to hydraulic oil) of 100 micron each,

or according to the coating supplier’s recommendation.

The first coat to be laid without delay after grit- or sandblasting and dust cleaning.

Tanks in stainless steel should not be coated.

Pipes and parts for oil filling and air venting will remain empty for longer periods and may corrode.

The pipes are almost impossible to clean and coat properly inside, and we therefore recommend to

use only stainless pipes. Copper- or galvanised pipes must not be used.

Air filters may be assembled directly on the tanks to avoid pipes.

4 HYDRAULIC DRIVEN EQUIPMENT – WINCHES, CRANES ETC.

To ensure correct function of the complete system, the yard is responsible for the adaptation of

their equipment connected to the Framo cargo pumping system.

The Framo hydraulic system is operating at constant pressure, and hydraulic oil consumption is not

accepted from any equipment during stand still condition.

In addition to the general requirements, the equipment must comply with the following:

- Separate service valves for each unit’s pressure-, return- and drain line to be included by the

yard, making it possible to do service without stopping the complete system. The valves are to

be installed in the pipelines, not as part of the control valve assembly.

- Manometer test connections must be provided by the yard both on pressure- and return side,

making it possible to do trouble shooting and to check for pressure peaks.

- Air venting valves/plugs must be installed on the highest possible point on both

pressure- and return side of the equipment.

- The equipment must not transmit pressure surges into the system, and must therefore have

possibilities for limiting the response time (flow variation). Accelerating/retarding time from

0 – to maximum and from maximum – to zero oil consumption must be >2,0 seconds.

- The equipment must have a pressure compensated flow limiting valve on the pressure inlet side

to avoid motor over-speed.

- Hydraulic motor housing and shaft sealing system must be designed for a hydraulic return

pressure of minimum 10 bar to avoid separate drain lines.

- Shaft sealing systems must have protection against sea water, air and contaminant intrusion.

- If separate drain lines are installed, drain oil filter with dirty filter indication/alarm to be included

by the yard. Minimum filtration ratio B15

³ 200.

- Separate hydraulic internal reservoirs or drain tanks are not acceptable.

- Generally Framo do not accept hydraulic cylinders connected to the system. For cranes with

hydraulic cylinders, use a separate hydraulic system with a hydraulic motor driven from the

Framo system.

- All equipment must be properly cleaned to meet ISO contamination code 4406 class 15/11 or

better prior to installation. Oil used for cleaning, testing and preservation must be compatible

with the oils meeting Framo requirements.

2 ARRANGEMENT

The cargo heater should be located close to the drop line. The following figures give examples of

optimal piping layout.

Fig. 3

Not ice the fo l lowing

to get a proper instal lat ion:

- The piping must be routed with built in

flexibility to avoid excessive nozzle loads at

the heater and pump connections, and to

reduce vibrations being transmittet to the

heater connections. See mounting instruction

for cargo piping.

- The cargo line to and from the heater should

be same size as the heater connections.

- Pipes to be supported to avoid excessive

load transfered to the heater connections.

- All piping must be self-draining.

(Sloping towards drop line or cargo pump)

- The cargo inlet line must have drain connection.

- Cargo valves must be located close to the

discharge line/drop line.

This is to avoid contamination of the cargopipes to the heater when it is not in use.

- Easy access for operation of valves.

- The relief valve should be connected to

the drain line/drop line.

- To prevent frost damages drain valve must

be installed at the heating inlet and outlet lines.

- Angular service spools that can be

removed for service.

- The Framo cargo heater should be installedwhere it is protected from sea that breaks

over the ship.

4 EXAMPLE OF PUMP INSTALLATION WITH FRAMO DUMMY

Prior to pump installation the deck trunk and brackets for intermediate and bottom support have to

be welded into the tank. Use of Framo dummy will help you to get a successful installation of trunk,

bottom support bracket and brackets for intermediate supports.The following installation procedure is based upon use of Framo dummy.

Note! It is important that the trunk and brackets for supports are welded into the ship at

the latest possible stage to ensure correct position according to dimensional drawings.

4.1 Framo dummy

The dummy has brackets simulating all interfaces to flanged pipe connections on the pump’s top

plate for adjustment and prefabrication.

Note! It is neccessary to remove the flange protection for deck trunk (plywood) when using

the top plate dummy. It is important to remount the protection after use of dummy.

The “dummy equipment package” is shown below. For lengths, see Framo specification.

5 PREFABRICATION OF DECK PIPING

When the trunk is installed, the top plate

dummy can be used for adjustment/

prefabrication of the piping.

- Remove the laser from the top plate dummy.

- Assemble the brackets for the actual

connections (ref. drawing of top plate dummy).

- Bolt the top plate dummy to the trunk in

correct position (see dimensional drawing

for top plate).

The dummy can now be used for adjustment of

the piping by fixing the pipe flanges to the

relevant positions/brackets on the dummy.

6 ASSEMBLING OF PIPE STACKS

The pump is to be assembled in a horizontal position. Every pump part is to be supported in at least

two points.

Note! The pumps must not be in contact with carbon steel.

Fig. 19

Check that pump no. on all the pump parts are identical. Pump no. is placed on top plate and

flange for suction box. Locate the pump parts in correct positions one after another. Every part

is to be supported in at least two points

Note! Be careful not to damage the sealing surface on the deck trunk and

protect the seal faces by the supplied plywood after this operation.

Note! Pumps with total length above 20 meters have to be assembled during installation in tank.

Never grind acrossseal face


7.1 Preparations

Note! Welding, sandblasting and grinding must be finished and tank must be properly cleaned

before installation of pump in tank.

For carbon steel tanks, also coating must be finished before installation.

Pickling

Pickling will be required prior to installation if the pump has been exposed to iron dust during

storage or corroded surfaces/spots are detected. Framo recommend Avesta Pickling Paste or

equal types for stainless steel.

Follow the manufacturer’s procedure for pickling before starting the work.

Blank flanges

Blank flanges and seals on top plate shall be left until connection of the pump to the vessel’s pipingsystems. By then the piping system has to be inspected for foreign bodies and cleaned.

The blank flange/protection cover on the pump’s suction opening and the protection around the

pump shaft must be kept on until pump has been installed and tank has been cleaned and

approved. The protection shall be removed only by the Framo service engineer.

Special tools required for installations are supplied by Framo in the toolbox.


Bottom support /Intermediate support(s)Install the support(s) on the bracket(s) before

installation of pump.Tighten nuts as follows (fig. 24):

1) Assemble upper nut, use 190 Nm torque.

2) Tighten all bolts one more time,

use 190 Nm torque.

3) Assemble lower nut, use 190 Nm torque.

Deck trunk

Remove the flange protection and inspect the

sealing surface on the deck trunk flange.Required surface roughness is Ra 1,6 µm.

If the sealing surface has been damaged

(scratches, grooves) during transport or

installation, the damages must be removed by

careful grinding/polishing by abrasive paper.

Note! If grinding/polishing is required,

this must be done according to fig. 25.

7.2 Installation

Clean the gasket groove in the top plate. Stretch the gasket

over the top plate, -take care not to damage the gasket.

The gastket has to be greased with teflon grease before

installation in the top plate. Gasket and grease are supplied byFramo. Install the gasket carefully in gasket groove while the

pump is still lying hoizontal.


Install lifting tool on the top plate (supplied by Framo in the toolbox)

Lift the pump to a vertical position. Two cranes should be used to raise the pump to vertical position,

one crane for lifting, the other for keeping the lower part clear of the ground.

The lower part must not be allowed to slide along the ground during lifting.

For pump above 12 metres it is recommended to use a snatch block on the lower part.Minimum length of the wire through the snatch block = 2 x length of the pump’s lower part.

Lower the pump until the top plate rests on the

deck trunk. Be careful when the guiding pins

enter the deck trunk holes.

Install rubber bushings and hexagon head boltsunder the trunk flange. Use Loctite on the bolts.

Tighten bolts in a diagonal sequence to 44 Nm.

Remove the two guide pins, and install the two

remaining rubber bushings and bolts.

Tighten bolts to 44 Nm.

Note! Don’t remove any blank flanges on the top

plate and flexible bellow before final piping

connections.

7.3 Additional information during installation of pumps above 20 meter

Note! The pump has to be pressure tested after assembling and installation in tank.

This requires an arrangement in tank which give access to the flange connections

in pipe stack.

Lower part

Install the lifting tool on pipe stack.

Lift the pump head section into the tank.

Stop lowering when pipe stack flange is

approximately 0,5 m above deck trunk.

Install the securing tool on the deck trunk

(see actual tool drawing).

resting on the securing tool (fig. 31).

Secure the lower part before removing the

lifting tool.

Upper part (top plate section)

Remove the blank flanges. Clean the

all O-ring grooves with a clean and dryrag. Lift the upper part in position

above the deck trunk.

Continue lowering until the distance

between the flanges is 50-100 mm.

Install lifting bolts (toolbox) and lift the

lower pipe stack section by using the

lifting bolts. Be careful when the

connection pipe enter the high

pressure pipe. For assembling of

flanges, see page 14.

8 FILLING OF PUMPS COFFERDAM

- Hydraulic oil filling of pump must be done before

cofferdam filling.

- Fill the cofferdam through the header tank until

the liquid level stabilises just above low level

mark on the sight glass (filling tool included in tool

box).

Fill up cofferdam and header tank with:

Ethylene glycol or propylene glycol * : 50-60 %

Use pure glycol without additives.

Commercially available automotive anti-freeze

should never be used. Some of the additives inanti-freeze tend to form deposits on seal parts and

thereby causing failure on the seals.

Demineralised water : 40-50%

Freezing point~ - 35°C v. 50% glycol

Freezing point< - 40°C v. 60% glycol

Volumetric

expansion : 0 - 60°C ~ 63.5 x 10-5 litre/litre°C

- The cofferdam volume depends on pump type and

pump length. The following formulas give approx.

volume (in litres) required to fill cofferdam to

low level mark in header tank:

L=Pump length in metres. (See Framo Specification)

HYDRAULIC PIP

1 DESIGN

1.1 Optimum hydraulic pipe layout

All hydraulic lines, including expansion loops, must be routed in order to avoid air pockets.This is applicable also for pilot lines.

Key items are:

• All pipes must be resilient mounted, except pilot pipes on deck.

• Acceptable load on resilient pipe clamps. • All pipe supports, pipe clamps and anchor points must be welded to

rigid structure.

• Bending of pipes where possible, in order to reduce quantity of flanges and fittings.

• Carbon steel pipes must be painted with final coating system beforeinstallation on open deck, to avoid corrosion in clamping zone.

Optimum designThe benefits of optimum design are:

• Reduced quantity of pipe components (leakage possibilities)

• Reduced installation time• Reduced pressure drop

• Increased life time

• Reduced maintenance cost

1.2 General requirementsTo obtain a long lasting and well functioning hydraulic plant, cleanliness is of great importance.Framo’s requirement is to keep the pipes and components clean and preserved during thewhole production and installation period.

Following must be considered during layout of hydraulic pipes:

• Spool length up to 12m where practical

• Stress caused by the system pressure

• Thermal expansion caused by temperature changes in the system (max. oil temp. 60°C)

• Mechanical forces caused by deflection of ship structure

Documentation:

All material used must comply with classification society rules, regarding material certificates andproduction documentation.

1.3 Detail designHydraulic pipe spools must be designed to ensure visual inspection for all inside weld seams,ref. fig. 4. Use of instruments like videoscope or similar is an acceptable inspection method.

1.4 Branch lines

In order to reduce stress in branch lines and main lines from thermal expansion and deflection of ship, the following tables for duplex, stainless steel and carbon steel must be used for optimum

hydraulic pipe design.

Figure 7, 8 and 9 show how the required flexibility length (L-U) changes with increasing pipe dimension witha small total piping length (one curve for all pipe dimensions) and a large total piping length (four curveswith several pipe dimensions) when assuming a maximum differential temperature ∆Tmax=50ºC (FDP).The intersection of the above mentioned curves and the upper flexibility limit will indicate the requiredflexibility length (L-U) on the axis of abscissas.For a given pipe dimension a total piping length smaller than L=15m will also require a smaller flexibilitylength (L-U) somewhere between the maximum value and the minimum required flexibility length for L=5m(linear interpolation can be performed).

D = outside diameter of pipe (mm)L = developed length of piping between anchors (m) (L1 + L2 + L3)U = anchor distance, straight line between anchors (m)K = flexibility characteristic (-)

1.5 Critical length of HP branch linesThere is a connection between pump length and the length of HP branch lines, due to pressurewaves and pipe sizes. If HP branch line is above critical length, there will be a risk of vibration.

To avoid vibration in branch lines, table fig. 10 shows critical pipe length for branch lines topumps. This is in most cases only applicable for submerged ballast pumps and pumps in decktanks. Pipe dimensions given in Hydraulic Diagram are standard pipe sizes.

1.6 Service spools at cargo pumps and resilient pipe clampsHydraulic pipes must have an angular service spool at pump in order to make lifting of pumpspossible.

1.8 Noise reductionIt is of great importance to isolate hydraulically driven equipment and connected piping from shipstructure by us of:

•

Resilient pipe clamps• Resilient bulkhead penetrations

• Resilient anchor points, horizontal/vertical

1.8.1 Installation of resilient pipe clampsDue to fabrication tolerances on pipe supports and prefabricated pipes, pipe clamps must bepossible to adjust in order to have similar compression on rubber pads.Pipe supports must be welded to rigid structure, ref. fig. 19.

Recommended procedure :

1. In order to make adjustment more easy, resilient pipe clamp to be welded to an angle bar or similar, prior to spot welding to pipe support.

2. Check acceptable load for resilient pipe clamps.

3. Angle bar with resilient pipe clamp must be spot welded to pipe support.

4. After all pipes are in position and aligned, angular bar must be adjusted, if necessary tosimilar compression on rubber pads. Clamps must not be overloaded.

5. Welding of bracket to be completed.

Note! Carbon steel pipes mu st be painted with comp lete paint ing system before instal lat ion, to avoid corros ion in clamping zone.

Following pipe lines must be resiliently installed:

1.10 Flanges and connections

Flanges

In order to get a leakage free hydraulic system it is of great importance to use flanges with cleanand damage free “flange face”. Any damage on sealing surface may cause leakage.

Note! “Flange face” must be protected dur ing product ion period in worksho p.

Recommended type of flanges to be used:

High pressure: Low pressure:

O-ring Flat gasket O-ring

Fillet weld

1.11 Expansion loops

It is important to be sure that sufficient number of expansion loops are used in the hydraulic

piping system. Expansion loops must be horizontal mounted. For dimensions, see Framo PipingCatalogue.

Low pressure

High pressure

Location and number of expansion loops depends on thermal expansion of the hydraulic systemand deflection of ship structure.

For accurate calculation of thermal expansion the following formula can be used:

∆L = L ⋅ α ⋅ ∆T Material α L = Length of pipe

α = Thermal expansion coefficient

∆T = Temperature difference in °C

3 INSTALLATION ONBOARD

3.1 General requirements for installation onboard

Key items are:

• Prefabrication of hydraulic pipes in workshop up to a possible extent of (∼80-85%).

• Hydraulic pipes and components must be kept clean, preserved and blanked off during theinstallation period.

• Ensure that blank flanges are fitted to all connections until final assembly on board.

Note! Open ends wi l l lead to contamination of the hydraul ic system.

• Alignment of pipes must be checked, and axial gap must not exceed figures given in fig. 54.

• Alignment of pipe clamps must be checked, and adjusted if required.

• All pipe supports must be welded to rigid structure.

• Pipe supports must be designed to take forces from piping system and anchor points.

• Axial clearance in resilient bulkhead penetrations must be checked.

Note! Hemp, codi l le , tow and seal ing comp ound as Permatex or s imi lar must never be used

in a hydraul ic p ip ing system.

BLOCK (UNIT) INSTALLATION

Pre-outfitting of hydraulic pipes in blocks (units) may cause problems regarding misalignment of pipes and pipe clamps.

To prevent misalignment and leakage following details are important:

• Pipe clamps must not be welded before assembly of blocks and alignment of pipes.

Fig. 58



No. 1401-0017-4Rev. A Sep-2002

26 of 26



• Adjusting spool pieces must be minimum 2 - 3 m long in order to give sufficient alignment.

• During installation of adjusting spools, pipe ends must be moved (forced) 3 - 5 mm inlongitudinal direction in order to avoid damage of o-rings.

Fig. 59

3.2 Tightening torques for boltsIn order to obtain correct pretension, the threads, plus screw heads and contact surface of nutsagainst foundation, must be clean and lubricated before tightening.

The lubricating agent should be Molybdenum sulphide on screw connections of stainless steel

type (A4-80 or similar).

If pneumatic or electric hammer is used during assembling this should be used for light tightening, followed by tightening with a torque wrench.

If no torque is specified in service instruction or on drawing, use tightening torqueaccording to table:

1 GENERAL

This document is intended as a guide with some examples for possible cargo piping on

Chemical carriers, Oil product- and Crude oil tankers. Other design criteria may apply for FSOP’s and OBO’s.

The cargo piping arrangement will depend on type of vessel, cargoes to be carried and number of segregations, but should always be arranged for optimal efficiency regarding loading,discharging, draining and cleaning.

In addition to the different authorities and owner’s requirements, the following main items mustbe considered during design:

- Cargo piping material.- Segregation and a minimum risk of cargo contamination.

- Self-drainage or easy draining of piping and components.- Optimal arrangement and number of valves.- Valves. Type-Material-Operation (remote and/or local operation).- Number of flanges reduced to a minimum.- Easy access for operation and maintenance of equipment.- Service spools for dismantling and maintenance of equipment.- Maximum cargo pressure and equipment design pressure.- Mechanical forces from ship structure.- Anchor points and expansion loops.- Resilient pipe clamps close to the Framo cargo pumps.- Flexibility between Framo cargo pumps and cargo drop line.

From a stripping point of view, an arrangement with the manifolds (crossovers) below cargodeck lines, and with the deck lines sloping against the manifolds is preferred. From a loadingpoint of view, an arrangement with the manifolds above cargo deck lines is preferred.Plus- and minus for the different arrangements are given in page 6, and regardless of manifoldlocation, arrangements should be made to reduce or avoid the drawback of the selecteddesign.

Cargo can be loaded through the Framo submerged cargo pump, but the loadingcapacity/pressure is limited by an anti-rotation brake in the pump, (preventing the impeller fromrotating during loading).Separate cargo drop lines should always be installed to obtain a satisfactory loading rate, and

also to make it possible to by-pass the cargo pump during loading.

For cargo circulation (cargo heating with deck heaters or circulation of cargoes with highcontent of sediments), the drop line outlet in tank should be as far away from the cargo pumpinlet as possible.If limited space on deck, drop lines may be routed inside the cargo tank.

Pressure transducers for remote reading of cargo pressure should preferably be installedbetween the cargo pump and the cargo valve, making it possible to read the cargo pressurewhen the cargo pump is running, even with closed cargo valve.

2 CHEMICAL CARRIERS

A typical chemical carrier has normally fully segregated cargo tanks, i.e. one pump, one cargoline and one manifold for each tank.

Cargo piping material is normally stainless steel.

Efficient stripping and cleaning of cargo pipes after discharge are normally given the highestpriority, and we therefore recommend that the cargo deck line is sloping toward the manifold asshown in fig.1. For different arrangements, see page 6.

(R) = Remotely operated valve is recommended.

3 OIL PRODUCT - AND CRUDE OIL TANKERS

Oil product and crude oil tankers usually have 2 - 6 segregations with two or more submergedcargo pumps connected to each cargo line and manifold.

Fig. 2 shows a typical arrangement with two pumps connected to one common cargo deck lineand manifold (crossover).

Cargo pipe material may be stainless steel or coated carbon steel.Maximum flow velocity should not exceed 6 m/s in stainless steel pipes, and 3,5 m/s in coatedpipes (or flow limits given by the coating supplier).

- Coated carbon steel pipe dimensions have to be increased compared with stainless steel toobtain the same loading and discharge rate due to the lower flow velocity limit. Limited spoollengths are recommended to ensure proper coating and satisfactory inspection.

- Stainless steel piping gives reduced dimensions, reduced number of flange connections,reduced weight, and reduced volume of cargo and washing water to be drained from the

piping system. Flushing with fresh water after eventual tank cleaning with seawater isrequired.

Due to the ship size and large cargo pipe- and manifold dimensions,it is most practical to install the cargo deck lines parallel to deck.

It is recommended to install a common drain line to improve the stripping and cleaningpossibilities for the cargo lines after discharge.

4 SELF - DRAINING

During the last years, efficient stripping of cargo tanks, pumps and its associated piping system

has been a very important part of the cargo handling operation.

General key words:- Minimum cargo left onboard after stripping.- Shortest possible stripping time.- Lowest possible Air/Inert gas consumption.- Easy cleaning.

When designing the cargo piping system, the key word is Self-Draining, both for piping andcomponents. Even small details may improve the drainage possibility.The piping should be self-drained without pockets and “dead pipe ends”.Typical examples are shown in fig.4.

Drain

Fig. 4

Separate drain lines may be used to compensate for non self-drained pipes, but this inducemore lines to be cleaned, and discharge time (time for emptying the cargo lines) will normally

increase.

Possibilities for easy draining of manifold and/or cargo deck piping to slop tanks should bemade.

Equipment such as cargo deck heaters and its piping must be self-drained to tank through thecargo drop line as shown in fig. 3.

4.1 Cargo deck lines above manifold

For cargo deck lines sloping against the manifold,

During discharge and stripping the ship is normally trimmed by the stern, and cargo deck linesforward of manifold may therefore be parallel to deck.

4.2 Cargo deck lines below manifold

For cargo deck lines sloping toward the pump, separate drainlines and drain connections must be installed.

The Framo cargo pumps are resilientmounted to the deck trunk, and minimum 2of the pipe clamps close to the pump mustbe of resilient type to maintain the flexibilityand to avoid vibrations being transmitted tothe deck structure. (Fig. 12).

If the cargo drop line is connected close to thepump as shown in fig. 13 also the drop linemust be resilient clamped. The drop line mustbe routed to have sufficient flexibility to avoid

expansion forces being transmitted to thepump.

The drop line outlet in tank should be as far away from the pump’s suction inlet aspossible, especially for installations with cargodeck heaters where the pumps are used for circulation.

1 SELECTION OF HYDRAULIC OIL

Hydraulic oil is a very important part of the Framo hydraulic system and must meet the below

specification unless a different specification is received in writing from Frank Mohn AS.

GENERAL OIL SPECIFICATION

1. DIN 51524 part 2 for antiwear hydraulic oils type HLP.

2. Sperry Vickers 35VQ25 A11XX20 test (as described in Sperry Vickers form M-2952-S).

3. FZG A/8,3/90 test, load stage 10 according to DIN 51354 part 2.

4. Viscosity ISO VG 46 according to ISO 3448.

5. Viscosity index. Minimum 95 according to ISO 3448.

6. Pour point: Max. -26°C according to DIN 51597.

Note! Re-branded oil is not acceptable.

Trade names

According to present information received from the oil companies, the trade names listed below are

available world-wide and valid for ISO VG46-oils in Framo systems. Formulation of different oils is

however a continuously changing process, and it is the responsibility of each oil company to supply

hydraulic oils meeting the General Oil Specification.

COMPANY TRADE NAME

ANTAR VISGA 46 *

BP BARTRAN 46BARTRAN HV 46 *HYSPIN AWH-M 46 *

EXXONMOBILDTE 25DTE 15 M *

FAMM RANDO OIL HD 46 RANDO OIL HD Z 46 *

SHELLTELLUS 46TELLUS T 46 *

TOTAL FINA ELF VISGA 46 *

* High viscosity index oils (VI > 140) are only required for low temperature applications.

If a high V.I. oil is to be used, an oil viscosity of 50-55 cSt at 40°C must be used for initial oil filling,

if necessary by mixing with an ISO VG 68 oil. Mixing ratio to be informed by oil supplier.

If an hydraulic oil not listed above is intended to be used, Framo must be contacted for comments.

Mixing of different hydraulic oils should be avoided. If different hydraulic oils have to be mixed, the

oil companies in question must run a compatibility test and guarantee the compatibility prior to

mixing.

Note! Only hydraulic system oil must be used for flushing after installation on board.

2 CLEANLINESS REQUIREMENT

High pressure hydraulic pumps, motors and control valves have close tolerances and require clean

hydraulic oil to obtain reliability, good performance and long lifetime.

Contaminated oil will not provide satisfying lubrication and is a leading contributor to reduced

efficiency, excessive down time and increased maintenance costs.

There are three types of possible contamination in hydraulic systems:

- Solid particles Increased wear, reduced oil- and component life time, sticking valves,

unexpected system shut downs.

- Water Reduced lubrication, generating of metal particles to the

system, corrosion, reduced life time for oil and components.

- Air Pressure shocks and serious damage to hydraulic pumps, motors,

piping and other components, loss of oil and oil pollution.

The contamination may enter the system:

- During production and assembling of the system.

- During hydraulic oil filling. (New oil from supplier, refined and blended under “clean” conditions

is not clean).

- Together with the atmospheric air through air venting on the hydraulic tanks.

- By wear and tear generated within the system.

- During service.

To prevent contamination, it is important to maintain a high standard of cleanliness at all

times.

- Keep pipes and components clean and protected during the whole production- and assembling

period.

- The hydraulic oil must always be filtered by using the Framo hydraulic oil transfer unit when oil

is filled into the system from the storage tank.

- Oil filling must be done without mixing air into the oil during oil filling. It is very time-consuming

to get rid of air when it is mixed into the hydraulic oil.

- Hydraulic tanks must be vented indoor and if possible through air filters.- Wear and tear to be prevented by checking the hydraulic oil quality and cleanliness regularly,

and by replacing filter elements when necessary.

- Keep all parts clean during service and assembling. Refill with clean oil, vent and flush carefully

after assembling.

Cleanliness level:

The required cleanliness level is based upon ISO Solid Contaminant Code ISO 4406. The code

was revised during 1999 and are now referring to 3 sizes of particles, 4 - 6 - and 14 micron(c).

(Previous code referred to 5 - and 15 micron).

A typical result according to the revised code will be 18/16/12.Framo will only use the two last digits referring to 6- and 14 micron(c).





No.1401-0019-4

Rev.C Dec-2002

Page 4 of 12

The highest level of particles accepted in Framo systems is code 16/12.

Recommended cleanliness level during circulation and flushing is code 15/11 or better.

When reporting a particle count, it must be reported how the particle counting has been carried out:

- According to previous ISO 4406.- According to revised ISO 4406 (1999).

- By optical microscope.

Water content

The water content must be below 300 PPM (0.03 %).

3 LEAKAGE AND PRESSURE TESTING OF PIPING SYSTEM

The hydraulic system must be pressure tested to ensure that it is correctly mounted and not

leaking.

It is recommended to carry out a leakage test of the piping system with clean nitrogen gas at low

pressure before oil filling in order to locate possible leakages in the system without causing oil spill.

For final pressure testing with hydraulic oil, Framo requires the following minimum test pressures:

- Pressure lines: According to the classification society requirement

or at least system pressure + 70 bar.

- Return lines: 11 bar

The Framo commissioning engineer must be informed in due time before pressure testing.

Note! Framo equipment is pressure tested in the factory before shipment and must be

bypassed during testing.

3.1 Leakage testing

The nitrogen gas bottles must be equipped with separate relief valves to take care of the safety.

Before testing is started, every pipe connection and fitting is to be checked, and bolts re-tightened

to assure that there are no loose connections.

Disconnected pipes and equipment must be blanked off. All blank flanges on HP pipes should have

venting plugs for air venting when pressure testing with hydraulic oil.

It is recommended to adjust and keep the nitrogen gas pressure at approximately 3 bar while every

connection on the piping system is examined by means of a soap-water mixture in order to locate

possible leakage.

3.3 Pressure testing with hydraulic oil

Hydraulic pipes must be pressure tested with hydraulic oil.

Water or other fluids must never be used for pressure testing.

For pressure testing of the pressure lines, a special and cleanpressure testing pump must be used.

Note! The hydraulic power unit must not be used for pressure testing.

3.2 Safety

The hydraulic piping system is under very high pressure during testing.

Every possible action must be taken by the Yard in order to avoid damage both to man and

material.

Note! Before pressure testing is started every person not participating in the pressure

testing itself should be evacuated from exposed areas.

All access to the ship to be marked with signs, for example as shown below.

To have an overview of the hydraulic system there should be one person in charge for the pressure

testing. One person to be looking after the system in the power pack room, one in the pump room

and others on strategic places along the piping system. They must have communication equipment

enabling them to inform the person in charge if a leakage occurs.

Necessary equipment for collecting and removing of hydraulic oil must be available in case of

leakage.

Note! If hydraulic oil is leaking from the piping system during testing, the test pressure

must be set to zero. Leaking oil must be collected immediately and exposed area

cleaned.

The hydraulic oil must be drained out before any repairs are made on the piping system.

Hydraulic oil is slightly toxic, but will not cause bodily harm during normal use according to oil

companies information. However, be aware of that:

- Long lasting contact with the skin may cause skin irritation. Cover the skin or use protecting

cream when working with hydraulic oil.

- Oil into the eyes is normally not dangerous, but painful. Rinse the eye with fresh water for at

least 15 minutes.

- High concentrations of oil mist can irritate the respiratory organs.





No.1401-0019-4

Rev.C Dec-2002

Page 7 of 12

For pressure testing of the return lines, the hydraulic oil transfer unit can be used.

Oil must not be filled into the system before the Framo commissioning engineer has inspected and

accepted the cleanliness of the piping system and the associated system- and storage tanks.

If the hydraulic oil cooler and/or main filter box have been supplied separated from the HPU, (for closed systems only) the return line in-between must be checked very carefully before oil filling.

Initial oil filling must be carried out according to chapter 4 and in co-operation with the

Framo commissioning engineer.

It is recommended only to fill oil into the hydraulic pressure lines and start with pressure testing of

these lines. If leakages occur during the test, the oil may simply be transferred to the return side

before repair, by using the hydraulic transfer unit.

Before oil filling, check that:

- All HP service valves (ball valves) are in open position and blanked off in the open end.

- All ball valves on the snap-on coupling stations are in open position, ref. fig.1.

- The system back-up valve is closed in order to reduce the leakage over the valve to a minimum.

For pressures above 315 bar, a small leakage is normal.

- The heating and venting valve is closed. For pilot operated heating and venting valve, HP

service valve to be closed. For test pressures higher than 350 bar, HP service valve to be open

and blanked off in the open end.

After oil filling according to chapter 4, item 4.1, and proper air venting:

- Start the pressure testing pump and adjust the pressure in small steps up to approximately 70

bar. After the pressure is stabilised, hold this pressure while the complete piping system is

checked for leakage.

- Leakage control must be made by visual inspection and by monitoring irregular pressure drops.

Note that normal internal leakage in some hydraulic components might cause a certain pressure

drop during the inspection period.

- The visual inspection of the piping system should be carried out in two steps. First a quick

overview of the system to ensure that there is no major leakage, then every connection has to

be checked for leakage.

- Continue to raise the test pressure in steps up to approximately 150 bar, and check for leakage

as described above.

- Finally, the test pressure is to be adjusted in steps up to max. pressure according to theclassification society requirement or at least system pressure + 70 bar for the pressure line

(ref. page 4). Hold this pressure until the complete piping system is examined for leakage

(minimum 10 minutes or according to the classification society requirement).

When pressure testing of pressure lines is finished, continue to fill the return lines according to

item 4.1. Pressure test the return lines (ref. page 4).

4 INITIAL OIL FILLING

Oil must not be filled into the system before the Framo commissioning engineer has inspected and

accepted the cleanliness of the piping system and the associated system- and storage tanks.

Initial oil filling must be carried out in co-operation with Framo commissioning engineer.

Necessary time for oil filling and venting depends on the system size, but in spite of limited time

schedule, we must emphasise the necessity of using the time needed to fill oil and get air out of the

system by proper venting.

The oil must be filled slowly into the lowest possible connections, making it possible to fill up the

pipings gradually while the air can escape through the open venting connections on the highest

points. It is very time consuming to get rid of air when it is mixed into the hydraulic oil, and mixing

must therefore be avoided.

If possible, the ship should have aft trim if the power unit is located aft, and forward trim if it is

located forward during oil filling and venting.

Venting must be done from all the high points in components and system.

If deck machinery is connected to the system, these are normally the highest points.

Only the hydraulic oil transfer unit should be used for oil filling of the system.

Capacity is given in Technical Data.

4.1 Oil filling before pressure testing

- Fill up the storage tank.- Prepare for pressure testing according to chapter 3.

- Open venting connections on the pressure side highest points.

- Drain off a small quantity of oil from the storage tank for visual check.

- Connect the transfer unit flexible hoses. Suction to T and supply to HP (ref. fig. 1), and

open the valves for oil filling into the HP line.

- Vent the hydraulic oil transfer unit, and check direction of rotation.

- Start the hydraulic oil transfer unit and fill oil into the high pressure line.

- Vent all pressure branch lines when the main pressure line is filled.

- When all the pressure lines are completely filled and vented, stop the transfer pump.

- Let possible air settle for at least 12 hours, then start pump for refilling and venting.

- When all air seems to be out, stop pump and disconnect flexible hoses.

Pressure test the pressure lines according to item 3.3.

When pressure lines are tested, start oil filling into the return lines.

- Open all the venting connections on the return side highest points.

- Connect the transfer unit flexible hoses. Suction to T and supply to LP (ref. fig. 1).

- Vent all return branch lines when the main return line is filled.

- When all the return lines are completely filled and vented, stop the transfer pump.

- Let possible air settle for at least 12 hours, then start pump for refilling and venting.

- When all air seems to be out, stop pump and disconnect flexible hoses.

4.2 Oil filling before flushing

All Framo components are flushed prior to shipment and need no flushing if the blanking

equipment is in good condition and kept on until final installation.

Our flushing procedure is based upon use of the Framo hydraulic power unit, and orifices must

therefore be installed in the pressure lines to ensure that the hydraulic pump pressure always is

kept above 50 bar. Required flushing flow for different return pipe dimensions are given in the

flushing diagram. The calculated flow and orifice dimensions are based upon oil viscosity

46 cSt, density 870 kg/m3, a Reynolds number of approx. 4000, orifice discharge coefficient 0,65

and pressure drop 50 bar over the orifice. For other viscosities and pipe dimensions, flow and

orifice dimensions may be calculated from the following formulas:

Fig. 2

Install orifices, and bypass as many components as

possible according to the flushing diagram. Orifices must

be installed so that the jet stream do not damage the

flexible hoses, refer to fig. 2.

We recommend using HP flexible hoses to avoid

collapsing due to bending. Minimum dimensions:

Required oil flow : Q = 8,7 x d x n/46 [l/min] d = Inside pipe diameter [mm]

n = Oil viscosity [cSt]

Orifice diameter : D = 0,3xQ [mm]





No.1401-0019-4

Rev.C Dec-2002

Page 10 of 12

When the pressure testing is completed and all preparations are made according to fig. 3 and the

flushing diagram, proceed as follows:

- Open the heating and venting valve and valve(s) in the main return line (Pilot operated heating

valve can be opened by plugging the pilot connection).- Connect the transfer unit flexible hoses. Suction to T and supply to HP.

- Check storage tank oil level and start oil filling into the pressure line.

- Check storage tank oil level regularly during oil filling.

- Vent all piping and equipment not bypassed, hydraulic pumps, valves, oil cooler

and main filter box.

- Stop transfer pump when the hydraulic system tank is filled and change suction

hose from T to C for circulation.

- Circulate and vent until the oil cleanliness level is 15/11 or better.

- Stop the transfer unit and disconnect the flexible hoses. The hoses must be

disconnected when the transfer unit is not used, and the valves to be closed.

5.1 Flushing procedure

When all preparations have been made according to item 4.2 and initial start-up of hydraulic power

packs are finished, follow the procedure given below. System pressure to be max. 70 bar.

Main lines

- Start one power pack and run at system pressure of max. 70 bar.

- Open the heating valve (Pilot operated valve can be opened by plugging the pilot connection).

- Run for approximately 5 minutes and take oil sample.

- Stop power pack.

- If cleanliness level is above 16/12, start circulation with jockey pump (for open systems) or

feed pump (for closed systems).

- When cleanliness level is 15/11 or better, start necessary number of power packs for flushing of

main return line. System pressure max. 70 bar. Manually operated heating valve can be kept

open, but pilot operated heating to be turned off and HP service valve to be closed. Open

service valves to necessary number of branch lines to obtain sufficient oil flow.

- Check cleanliness level regularly. If level increases above 16/12, stop flushing and start

circulation to reduce number of particles.- Fill in the Flushing report included in the Framo Commissioning Protocol.

- Flush until cleanliness level 15/11 or better.

- Check flow and temperature according to flushing diagram.

5 FLUSHING

Flushing is the last and final cleaning procedure in order to remove particles that has entered the

system during installation, and to bring the cleanliness of the system oil up to an acceptable level.

All Framo components are flushed prior to shipment and need no flushing if the blanking equipmentis in good condition and kept on until final installation. Use of the Framo hydraulic power unit for

flushing has proven to be the most efficient, time saving and practical procedure to avoid

unnecessary dismantling, oil spillage and possible entrance of contamination during assembling.

It is absolutely necessary that our procedure is followed very carefully if the Framo power

unit is used for flushing. Hydraulic pumps must not run with pressure below 50 bar.

Before starting the main hydraulic pumps for flushing, the hydraulic oil in the system tank must have

cleanliness level 15/11 or better.

An oil sampling procedure is included in the Framo Service Manual.

Note! Initial oil filling and start-up of the system has to be done by the Framo service engineer.

The oil flow must be turbulent in order to remove particles from the inner surface of the pipes and

transport them to the filter. Necessary flushing capacities based upon inside pipe diameters and oil

temperatures are given in the flushing diagram.

Oil flow for each power pack is given in Technical Data for the installation.

Recommended average oil temperature during flushing is 50°C.

The flushing time depends on system size, cleanliness and piping material. Stainless steel pipes

require normally less time for flushing than mild steel pipes.

The following figures may be used as a rough estimate:

- Main lines, 1st sequence: Approx. 6 hours

- Branch lines (each): Approx. 2 hours

- Main lines, 2nd sequence: Approx. 4 hours

6 OIL FILLING OF COMPONENTS, CIRCULATION AND VENTING

All by-passed components, cargo pumps etc. must be filled with oil and vented properly after

flushing to avoid air mixed into the system.

It is very important to get the air out of all components and hydraulic lines instead of having the

oil/air mixture back to hydraulic tank, hydraulic pumps etc.

Note! Oil filling has to be done slowly to let the air escape through the venting connections.

Air in the system is indicated by:

- Back flow to the hydraulic tank during stand still

- Great difference between tank level at low and high system pressure

- Foaming

- Discolorated oil

Please note that Framo is not responsible for damages caused by air in the hydraulic oil, or if the

system has been started without Framo commissioning engineer’s approval.

Branch lines

- Close the heating valve.

- Start necessary number of power packs for the arranged number of branch lines to be flushed

simultaneously.

- Open ball valve to the branch lines and follow the same procedure as for the main lines.- Continue until all branch lines are flushed to cleanliness level 15/11 or better.

Main lines, 2 nd sequence

- Start necessary numbers of power packs for flushing of main return line.

- Open the heating valve and ball valve to necessary number of branch lines to obtain sufficient oil

flow.

- Flush until cleanliness level 15/11 or better.

Pilot pipes and pipes with inside diameter less than 25 mmFor these pipes turbulent flow is not obtainable due to the high pressure drop. It is therefore required

that the pipes are purged with clean nitrogen.

Other methods like “Pigging” (special plugs blown through the pipe by using a special tool) may be

used, but the results depends very much upon pipe material, quality, welding and pipe lengths.

Please contact Frank Mohn Services AS if such methods are considered to be used.

COMMISSIONING - TESTING

1 GENERAL

The commissioning shall ensure that the delivered equipment, installation and its function are in

accordance with the Framo documentation, and to demonstrate the operational capabilities of the

system.The time consumption for commissioning depends on ship type and size, system size, and Yards

progress related to other equipment and parts of the ship which will effect the various activities

related to the Framo cargo pumping system. It is also related to a correct installation according to

Framo requirements.

In general the commissioning is divided in two sequences:

1. Verification of design and installation procedures, (normally not necessary for the 2nd and the

following ships in a series if the Yard personnel responsible for the installation are the same).

2. Final check-out and start-up

2 VERIFICATION OF DESIGN AND INSTALLATION PROCEDURES

The verification part should be a coordination meeting between Yard and Framo to ensure that the

engineering and the actual installation are carried out to both parties satisfaction.

This quality assurance meeting should be held at the Yard at an early stage of the installation. The

following personnel should participate:

From Yard : Outfitting and Design personnel. (It is very important that personnel responsible for

the actual installation on board are present during this meeting).

From Framo : Project manager (Technical dept.) and Project engineer (Service dept.)

Yard and Framo should appoint suitable time for this meeting, and the verification activity should

mainly be focused on:

- Handling and storage of Framo equipment.

- Review technical documentation.

- Location and installation of Framo equipment.

- Location and installation of Yard associated equipment.

- Hydraulic- and cargo piping installation.- Pre-inspection of installed equipment.

- Commissioning progress and schedule (to be worked out).

- Review the practical realization of the final check-out and start-up activities, requirements

for Yard assistance etc.

3 FINAL CHECK-OUT AND START-UP SCHEDULE

During check-out and start-up of the Framo Cargo Pumping System also other equipment on board

will be involved, such as auxiliary machinery and generators, cargo lines and tanks, cargo andballast valve systems etc.

Installation and commissioning of these systems must therefore be incorporated when planning the

various activities and time needed.

Delays and waiting time caused by insufficient planning or progress of the installation leads to

additional cost for the commissioning, which again have to be covered by the buyer. An effective

verification meeting will however improve the possibilities for a smooth and effective total

commissioning within the agreed timeframe given in the Framo Acknowledgement of Order .

As a guidance for the different Framo check-out and start-up activities, a typical example of aschedule is shown below.

4 FINAL CHECK-OUT AND START-UP

Please note that Frank Mohn Services AS must be informed minimum 2 weeks prior to start of the

final check-out and start-up. Also eventual revisions of the schedule must be informed.

The following assistance and services are required during the final check-out and start-up:

- Contact person at Yard responsible for the Framo Cargo Pumping System.

- Office with access to phone and fax for our service engineer.

- Labour assistance for our service engineer when required.

- Sufficient supply of electric power for running of all the installed power packs simultaneously.

- Sufficient fuel supply for running of diesel driven hydraulic power packs.

- Operational cargo lines, ballast lines and valve systems.

- Fresh water in cargo tanks.

- Compressed air or nitrogen for purging and stripping of cargo pumps.

Note! The hydraulic piping and associated hydraulic oil tanks must be approved by the

commissioning engineer prior to oil filling.

Before water is filled into the cargo tanks, the commissioning engineer must inspect

and approve the tanks related to cleanliness.

5 TESTING

Testing is to be supervised by Framo commissioning engineer and must be done according to the

classification society- and Framo requirements to fulfil the system guarantee.

It is very important that sufficient time is given for our engineer in co-operation with Yard personnel

to carry out testing, venting and adjustment of the whole system prior to official test or ships seatrial.

Please note that all components delivered by Framo are pressure tested before assembly.

Hydraulic power units are tested together with the controllers, and all hydraulically driven

equipment, cargo pumps, ballast pumps and other pumps are tested and certified by the

classification society before delivery.

If possible, use fresh water for test of cargo pumps. If seawater has to be used,

see below limitations:

- When possible, take fresh sea water in

open sea and avoid contaminated

harbour water.

- Empty the tanks as soon as possible

when the testing is finished.

- Flush the pump with fresh water.

The following tests are required in order to ensure proper function of the system and to issue a

Framo Completion Certificate:

- Hydraulic piping to be pressure tested according to the classification society requirement.

Pressure piping must be tested with a minimum test pressure of System pressure + 70bar. A special (and clean) pressure testing pump has to be used.

Return piping with a minimum test pressure of 11 bar. The hydraulic oil transfer unit can be

used for this test.

- Particle- and water test of the hydraulic oil.

- Acceptance test of alarms and shut down functions.

- Running of Yard equipment connected to the Framo system to ensure that no pressure

shocks are transmitted to the system.

- Running of cargo pumps, ballast pumps and other pumps.

It is recommended to do a stripping test for each cargo pump according to

Marpol 73/78 Water test procedure.

If additional tests are required, test requirements and procedures have to be evaluated and

approved by Framo.
