3 TECHNICAL DESCRIPTION

3.1 250t AHC Offshore Knuckle Jib Crane

A complete Active Heave Compensated electro-hydraulically operated MacGregor crane designed for

efficient and safe load handling, offshore lifting operations and subsea load handling. Other features include

ship to ship mode and personnel lift all depending on which options are declared upon purchase.

This crane is delivered and mounted on a circular foundation which, depending upon design, can be welded

or bolted to the vessel’s crane foundation. All main operational functions i.e. hydraulic luffing cylinders,

slew drive system, main, auxiliary and tugger winches are all controlled from a spacious fully equipped

operator cabin with good operating views to the vessels’ main deck and lifting zones.

Knuckle jib cranes were originally designed to keep the jib end, including the load, as low as possible to

reduce the pendulum motion caused by movement of the vessel. However, when these cranes are used to lift

the large and heavy objects, it is at times necessary to have more free-hook height to provide increased space

for lifting arrangements, slings etc.

HAT 250t crane

All our knuckle jib cranes are designed to lift the high loads with an extended knuckle jib. This includes

strengthen structure and cylinder system to deal with these forces. This feature provides operators with a

great flexibility during the planning of lifting operations.

When the crane is in the over-side working position, with the active heave-compensation (AHC) activated

and with the crane hook in the water, it is still possible to operate the jib and slew crane functions. This

makes load positioning possible and optimizes other crane functions without shutting down the AHC mode

or moving the vessel.


No.HMC4240 LKO 250 t 3000 m

On all larger MacGregor cranes the slew drive system components, including drive gears and motors, are

located inside the crane’s king. This simplifies the maintenance and inspections throughout the entire

lifetime of the crane and protects the components from the harsh environment/surroundings.

3.2 Electro Hydraulic Power Unit (HPU)

Complete electro hydraulic power unit for all the crane’s hydraulic functions. The HPU is a totally enclosed

unit mounted in the crane king. The hydraulic oil tank is built-in in the crane king structure. The oil pumps

are submerged in the oil reservoir. El.powered air fan coolers of sufficient capacity are supplied to avoid

overheating of the hydraulic oil.

3.3 Active Heave Compensation System, (AHC/AT)

By using the finest and most reliable motion sensors, position sensors and control system components,

MacGregor cranes provide the best possible active heave compensation performance on the market.

Accuracy measured to a few centimetres is achievable even under extreme heave conditions.

3.4 Dual Sensor System (Important Safety Function)

In our expert opinion, regulation sensors used in AHC/AT mode are of critical importance and are therefore

specifically focused on during the product design stage. A fail-safe sensor system with dual sensors has been

developed, tested and implemented in our products. This system with auto-takeover ensures unique winch

function reliability when operating in AHC/AT mode. The load cell is one of these sensors which have a

dual output (two channels). This enables the AHC/AT to continue (without stop) in case of a failure in one of

these channels. Another sensor is the winch position encoder which is original a Profibus sensor, while a

secondary independent analogue sensor operates without the Profibus system. If a failure in the default

sensor occurs, the secondary sensor takes over immediately, without shutting down AHC/AT mode. These

new features significantly increase the system reliability. The crane jib system is also equipped with dual-

sensors giving important feedback to the system in AHC/AT mode. The control system will automatically

switch to the second sensor if there is a failure in the primary one. All dual sensors will generate alarms if

there is deviation between them. This is to warn the operator at an early stage that one of the sensors is not

sending a correct value. The operator can easily switch between the sensors, unless one of them has totally

failed.


No.HMC4240 LKO 250 t 3000 m

3.5 Operator Cabin

The crane is equipped with a spacious operator cabin presenting a comfortable work place for the crane

operator. The operator cabin is equipped with an ergonomic and shock absorbed operator chair providing all

main crane operations via joysticks located on armrests either side of the operator’s chair.

Full operational status of the crane can be monitored and operational modes changed via the operators

control touch screen. The display shows various critical operational information such as: load in hook, load

vs. radius, operating temperatures, alarms etc.

The cabin is also fully sound insulated and equipped with an air conditioning system, close circuit TV

monitors (from main and aux winches) window wipers, signal horn, window sun-blinds, FM radio/CD

player, VHF / UHF radio and general instrumentation.

The standard cabin design provides a comfortable and user friendly environment to allow all types of lifts to

be performed in a safe and proper manner. The cabin can be upgraded according to customer’s requirements.

No.HMC4240 LKO 250 t 3000 m

3.6 Fully Integrated Automatic Grease Lubrication System

A fully automatic grease lubrication system supplies necessary and correct lubrication to various points on

the crane. This system significantly simplifies the maintenance of the crane. The advantage of the central

lubrication system is that it provides grease to points on the crane that may have difficult access and requires

additional equipment i.e. lift hire and working at height trained personnel. It also ensures that it releases “a

little grease frequently” as opposed to “too much grease infrequently”.

3.7 Emergency Power System, EPS

An emergency power system, consisting of a totally-independent pump/motor system with a separate remote

control panel, ensures a safe operation of the crane, even if the main power supply (and aux. 230V power

supply) fails. All crane and winch functions (not AHC/AT mode) can be operated at full load at reduced

speed.

3.8 Main Hook

Subsea swivel hook for single line lift.

3.9 Flood Lights

2 x Pendulum suspended 400W marine floodlight protected for marine environments. The lights are fitted on

both sides of the jib end.

3.10 Helicopter Warning Lights

2 x helicopter warning lights in marine enclosures. One mounted on top of the king/main winch and one in

front on the main jib.

3.11 Winch Camera Monitoring System

Complete camera monitoring system for all crane winches. LCD flat screen monitor mounted in the crane

cabin.

3.12 SPM Nipples in Main Electric Motors

All main electric motors are fitted with SPM nipples for condition monitoring.

3.13 Spare Slip Rings

6 available single rings for signal.

3.14 Remote Diagnostic Control system

Satellite communication based remote control system that gives service personnel immediate access to the

crane control system anywhere in the world. The remote diagnostic control system is free of charge in the

warranty period. After that, a yearly fee will apply.

3.15 FMEA

An FMEA analysis will also be provided as part of the final documentation.
