Indian petroleum industry is the energy lifeline of the nation and its continuous performance is
essential for sovereignty and prosperity of the country. As the industry essentially deals with
inherently inflammable substances throughout its value chain – upstream, midstream and
downstream – Safety is of paramount importance to this industry as only safe performance at all
times can ensure optimum ROI of these national assets and resources including sustainability.
While statutory organizations were in place all along to oversee safety aspects of Indian petroleum
industry, Oil Industry Safety Directorate (OISD) was set up in 1986 by Ministry of Petroleum and
Natural Gas, Government of India as a knowledge centre for formulation of constantly updated
world-scale standards for design, layout and operation of various equipment, facility and activities
involved in this industry. Moreover, OISD was also given responsibility of monitoring
implementation status of these standards through safety audits.
In more than three decades of its existence, OISD has developed a rigorous, multi-layer, iterative
and participative process of development of standards – starting with research by in-house experts
and iterating through seeking & validating inputs from all stake-holders – operators, designers,
national level knowledge authorities and public at large – with a feedback loop of constant
updation based on ground level experience obtained through audits, incident analysis and
environment scanning.
The participative process followed in standard formulation has resulted in excellent level of
compliance by the industry culminating in a safer environment in the industry. OISD – except in
the upstream petroleum sector – is still a regulatory (and not a statutory) body but that has not
affected implementation of the OISD standards. It also goes to prove the old adage that self-
regulation is the best regulation. The quality and relevance of OISD standards had been further
endorsed by their adoption in various statutory rules of the land.
Petroleum industry in India is significantly globalized at present in terms of technology content
requiring its operation to keep pace with the relevant world scale standards & practices. This
matches the OISD philosophy of continuous improvement keeping pace with the global
developments in its target environment. To this end, OISD keeps track of changes through
participation as member in large number of International and national level knowledge o
rganizations – both in the field of standard development and implementation & monitoring in
addition to updation of internal knowledge base through continuous research and application
surveillance, thereby ensuring that this OISD standard, along with all other extant ones, remains
relevant, updated and effective on a real time basis in the applicable areas.
Together we strive to achieve NIL incidents in the entire hydrocarbon value chain. This, besides
other issues, calls for total engagement from all levels of the stake holder organizations, which we,
at OISD, fervently look forward to.
Jai Hind!!!

Page No III FOREWORD
The Oil Industry in India is over 100 years old. As such, various practices have been in
vogue because of collaboration/ association with different foreign companies and
governments. Standardization in design philosophies, operating and maintenance
practices remained a grey area. This coupled with feedback from some serious accidents
that occurred in the past in India and abroad, emphasized the need for the industry to
review the existing state-of-the-art in designing, operating and maintaining of Oil and Gas
installations.
With this in view, the Ministry of Petroleum and Natural Gas in 1986 constituted a Safety
Council assisted by the Oil Industry Safety Directorate (OISD) staffed from within the
industry in formulating and implementing a series of self-regulatory measures aimed at
removing obsolescence, standardizing and upgrading the existing standards to ensure
safe operations. Accordingly, OISD constituted a number of functional committees of
experts nominated from the industry to draw up standards and guidelines on various
subjects.
The original document on ―Crane Operation, Maintenance & Testing (For Upstream)‖ was
prepared in the year 2002 by the Functional Committee on Crane Operation, Maintenance
& Testing (For Upstream). This revised document is based on the accumulated
knowledge and experience of industry members and the various standards and practices.
This revised document is based on the accumulated knowledge and experience of
industry members and the various standards and practices.
The figures and annexures used in the document are representative in nature.
We, at OISD, are confident that the provisions of this standard, when implemented in
totality, would go a long way in ensuring safe operation of the target group of locations.
Needless to mention, this standard, as always would be reviewed based on field level
experience, incident analysis and environment scanning. Suggestions from all stake
holders may be forwarded to OISD.

10. Outrigger mat of appropriate size should be placed below the supporting floats depending upon
ground condition.
7.5 CRANE DANGER SIGNS TO WATCH FOR
While working around crane, the operator should be careful about following eight danger signs of
improper operation. If any of the following occurrences are noticed at jobsite, immediately inform to
supervisor person before a catastrophe takes place.
Outriggers, crawler tracks, or tyres raised off the ground while operating- This is an
extremely dangerous condition which indicates the crane is being overloaded and may tip over or
collapse. The wrong move in this situation can cause a catastrophe.
Operating close to power lines or other dangerous objects- Electrocution due to contact with
power lines is the leading cause of crane related fatalities. Detailed regulations for proximity to
high voltage sources must be strictly enforced. Any potential danger should be pointed out to the
crane operator or a supervisor-but never touch the crane at this time.
Riding the load or crane hook- This is a serious violation of safety regulations. Crane structures
and cables have far lower strength margins for handling material than what is required for lifting
personnel. Workers must never be suspended from a crane boom unless an approved personnel
basket with mandatory safety equipment is used, and lifting procedures are strictly followed.
Visible structural damage on the crane- There is little or no back up system in the load-
supporting components of most cranes. A damaged component can fail completely and without
warning, causing the boom or load to fall.
Modifications made by adding extra counterweight or holding down the rear of the crane-
All job initiated modifications are illegal and may permit overloading the crane. If not approved by
the crane manufacturer in writing, these modifications can over stress critical structural
components, which could cause failure of the crane.
A crane operating near a trench or excavation- Cranes exert extremely high loads on the soil
near the tracks, outriggers, or tires. A crane set up in close proximity to an excavation can cause
soil failure, crane turnover, and possible disaster.
The crane is noticeably out of level while operating- There is no faster way to collapse a crane
boom than to impose a side force on the boom. Working out of level creates a dynamic side force
which means a crane collapse may be imminent.
“OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”
OISD – RP – 205 Page no. 13
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
The crane's hoist line is not vertical at all times during operation- This indicates improper
operation. A hoist line which is not vertical obviously indicates that the load is not hanging straight
down. Out of plumb loads can cause crane collapse by generating side forces on the boom. In
some instances, the crane may tip over if the load swings.
7.6 PRECAUTIONS FROM LIVE POWER LINES
Everyone in proximity to a crane, when energized lines are near, must stay alert. It takes
employee teamwork to successfully and safely operate under this combination of conditions.
Power lines can be hard for the crane operator to see. They sometimes appear to be either further
away or much closer than they really are. It is difficult for the human eye to accurately judge the
clearance between the crane's boom or line, and a power line. Fellow workers can help assure
that safe clearances are being maintained between the crane, the line, the load and the overhead
power line. The table below shows basic clearance minimums, which apply to all areas around the
power line-above, below or to either side:
Power Line Voltage (KV) Minimum Clearance (Feet)
up to 50 10
50 to 75 11
75 to 125 13 125 to 175 15
175 to 250 17
250 to 370 21
370 to 550 27
550 to 1,000 42
The following guidelines are intended to prevent crane accident due to electrocution:
While operating cranes in the vicinity of overhead electric transmission line, adequate precaution
shall be taken against accidental contact with the electric transmission line unless the same is
kept de-energised during movement of the crane.
Avoid storing materials around and especially underneath overhead power lines.
Locate all power lines on the job and make a drawing of where you will set up the crane.
Consider any overhead line "hot" until the owner or utility company verifies that it is not energized
and is visibly grounded. The line must be "cold" if minimum clearance cannot be met.
Look carefully before the boom is moved, particularly in congested areas of poor visibility. Get
additional workers to help with the move if a clear view of all areas is not possible.
Place a visual marker, such as a florescent line or flagging to mark off the danger zone.

OISD – RP – 205 Page no. 14
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
Communicate the lifting plan to all crewmembers every time you set up (after breaks and lunch).
Use proper hand signals for directing crane operations. Make sure all crew members understand
the signals.
Appoint a watch person who does nothing but watch the load every time you work in the proximity
of power lines.
Never work closer to power lines than the code allows. Power lines are not insulated and they can
arc across several feet.
If working near power lines cannot be avoided, contact the utility who owns them, have them de-
energized and visibly grounded. This takes pre-planning; most utilities require a minimum notice.
If lines cannot be de-energized, the utility must approve your work plan and install protective
barriers. Again, a full time watch person is required.
If one cannot move the crane away from the lines, stay in the cabin until the utility company
arrives and makes sure the lines are de-energized.
If a dangerous situation demands that you must exit the crane, ―DON’T CLIMB DOWN". Jump
away from the crane (a distance of 2 to 4 feet is usually far enough) and land with both feet
together as there may be areas in the ground with differing voltage. This will avoid having one foot
in an area of higher voltage than the other, which can be lethal. Avoid contacting the load, load
line or the crane. Ground crew should follow this same advice.
8.0 LOAD HANDLING
8.1 THE LOAD
Crane lifting capacities are based on relative motion conditions between the crane and the load to
be handled. All cranes will have one static and at least one dynamic load rating chart. These
charts must show the rated lift capacity for boom lengths and angles.
1. The appropriate load rating charts for the configuration in use must be in a position where they
are visible to the operator while operating the crane. The operator should know that the hook load
is within the cranes applicable static or dynamic rated load at the radius at which the load is to be
lifted.
2. The safe working load on the crane at each radius should not be more than 90% of the test load,
but in no case should the rated capacity loads be exceeded. The safe working load of the crane
should be legibly marked on it. A scale or weight indicator should be available which can be used
to determine weight of unknown load to be lifted.
3. Never attempt to operate a crane where the load capacity chart shows no load capacity or where
“OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”
OISD – RP – 205 Page no. 15
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
there are no values shown on the charts. This load is more than the safe operating conditions for
the crane. The crane can turn over when the boom is extended too far, even with no load
(Applicable to mobile crane).
4. To make a safe lift, the operator must know the exact weight of the load, the length of the crane
boom, the load radius and the boom angle.
5. For lifting heavy equipment shackles/hooks shall be engaged on lugs/eyes provided for lifting.
6. General load moment indicators do not sense extension of outrigger beams .As such, while
operating a crane, it should be ensured that the outrigger beams are fully extended.
7. Cranes should always be placed horizontally, as load moment indicator parameters are fixed,
assuming the crane in horizontal position. Any horizontal imbalance of the crane will result in
decrease of the balancing moment not accounted for by the load moment indicator, which may
lead to serious over-loading.
8.2 LIFT PLAN:
A written lift plan is to be made prior to lifting for non-routine (simple/ complicated/ complex) or
critical lift. Lift plan to tentatively include weight, dimension, limiting boom angle with its
corresponding SWL as per load chart and probable lift trajectory.
Classification of a lift as non-routine/ critical should be determined by company policy but may
also be determined independently by site supervision, project management, or a qualified
person. Critical lifts can occur anytime during lifting, preparation for a lift, or dismantling from a
lifting operation.
Lifting operation categorization help to provide the level of control required as per complexity
involved. Company will define lift categories. General guidelines on lift categorizations are given
below.
Non-Routine Lifts
Non-Routine lifts are further divided in to three categories
a. simple
b. complicated
c. complex or critical lifts
Simple Lifts
Below is the list to describe simple lifts
a. load with known weight and center of gravity below lifting points.
b. lifting points / pad eyes available above the load.
c. requires standard rigging arrangement to lift.
d. lifting area involved is standard designated load bay.
“OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”
OISD – RP – 205 Page no. 16
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
Complicated Lifts
Below is the list to describe complicated lifts
a. lifting operations involving two cranes simultaneously.
b. transfer of load from one vessel to other.
c. lifting in restricted area.
d. load having offset center of gravity.
e. lifts with large surface area.
f. signalman is likely to go out of sight of crane operator during course of lifting.
CRITICAL LIFT IDENTIFICATION
Examples of commonly accepted critical lift criteria are as follows:
i. The total load being lifted is in excess of a predetermined threshold. This threshold may vary with
company policy and with consideration given to such criteria as crane capacity, available rigging,
and employee experience.
ii. The lifted load exceeds a predetermined percentage of the crane’s capacity, as shown on the
crane manufacturer’s applicable load rating charts for the configuration being used. Responsible
management may adjust this percentage depending on the jobsite conditions.
iii. The lifting operation involves more than one crane lifting a common load with shared loading of
both cranes.
iv. The lifting operation involves more than one crane lifting a common load with shared loading of
both cranes. Multi-crane lifts utilizing one crane, as a tailing crane, may not be considered a
critical lift unless another of these listed criteria applies.
a. The item being lifted is unique and if damaged, would be irreplaceable or not repairable and
is vital to a system, facility, or project operation.
b. The item is being removed from a structure; such as in demolition work, where the actual
weight and the structural integrity are in doubt.
c. The lifting operation is within a boom length of power lines.
v. Other crane activities such as but not limited to the following, which may be considered as critical
lifts as determined by either site management or project supervision:
a. Lifting with limited clearance or in confined work areas.
b. Lifting at heights that make control of the load difficult.
c. Lifts utilizing specially engineered load rigging system.

5. When rotating the crane, sudden starts and stops should be avoided. Rotational speed shall
be such that the load does not swing out beyond the radius at which it can be controlled.
6. No external forces should be applied to suspended loads which will create side loading of the
boom. Care should be taken when swinging the crane so as to minimize the pendulum action of
the hook and suspended load.
7. Cranes will not be used for dragging loads unless properly rigged for a vertical pull not
exceeding the rated capacity.
8. The operator will not hoist, lower or swing while any personnel are on the load or hook
(other than in a personnel basket).
9. Suspended loads shall be kept clear of all obstructions.
10. All persons shall be kept clear of suspended loads or those about to be lifted.
11. While the crane is in operation, no other work shall be performed on the crane.
12. The operator should test the brakes each time a load approaching the rated load is
handled.
13. The operator should avoid moving loads over personnel. Loads which are suspended by use
of slings or hoists should be blocked or cribbed before personnel are permitted to work
beneath or between them. Blow horn before moving loads over the area where people are
working.
14. Riding on loads and hooks is strictly prohibited.
15. No fewer than five (5) full wraps of rope will remain on the drum(s) in any operating
condition. Due consideration should be given to hoist manufacturer’s recommended practices,
especially for ―break away‖ anchor type hoists.
16. All the cranes must be equipped with safety cutouts and the weight indicators. Safety
cutouts must always be in good working condition.
17. When two or more cranes are used to lift a load, one qualified operator will be responsible for
the operation. The responsible operator should analyze the operations and instruct all
personnel involved in the proper positioning, rigging of the load and the movements to be
made. The positioning of cranes and distribution of load should be ascertained.
18. Appropriate non-electrical conducting tag or restraining lines should be used where necessary
to guide and control the load.
19. The operator should not leave the crane controls until the load has been safely landed. He must
properly secure the crane and boom before going off duty when shutting down operations.

upon the angle of hitch, construction of the wire rope, web material and width etc. These rated
loads are provided by the manufacturer. These rated loads will be indicated on the heavy duty
tags attached to each type of sling at the time it is fabricated.
Care and use of slings and handling procedure should be in accordance with OISD-STD-187/
API-RP-9B/ ASME B 30.9.
9.0 PERSONNEL TRANSFER
Off- loading material and men from supply vessels to offshore installations and vice-versa in
a heavy swell, is always hazardous. Of all lifting operations, lifting of personnel presents the
greatest risk and shall only be considered if no alternative method can be found. It
requires quite an exceptional level of coordination between the captain of the supply vessel
and the platform crane operator. The latter only has a small ―time window‖ in which to start
hoisting the load to avoid it being hit by the heaving deck of the vessel. Personnel transfer
shall only be performed after assessing the risk, defining associated prevention and mitigation
measures and obtaining approval from the person in charge of the installation.
9.1 TRANSFER OF PERSONNEL BY BASKET
If sea is rough or wind does not permit vessel drawing alongside or if there is no landing
platform, personnel shall be transferred by using unsinkable basket. The personnel basket
should be so constructed, that it is capable of serving as a temporary life raft for the
maximum number of persons that it is designed to carry.
9.2 BASKET
Manufacturer's certificate, certificate of application and declaration of conformity, shall be
issued prior to operation.
9.3 USE OF PERSONNEL BASKET
When transferring personnel between an installation and a vessel by means of an offshore
crane and a personnel basket, the following precautions are recommended as basis for
setting up a procedure.

OISD – RP – 205 Page no. 27
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
10.2 USE OF HAND SIGNALS
It is frequently necessary during crane operation for the operator to depend on a signal man for
instructions, when moving an equipment into a position where there is very limited clearance
or when handling loads that are out of sight of the operator. The hand signals illustrated are
those generally accepted throughout the industry. Ensure both the operator and the signal
man are thoroughly familiar with standard hand signals to enable co-operation and teak work
The details of use of hand signals are attached at Annexure-A.
10.3 SIGNALMAN
The signalman shall be responsible for relaying signals from the slinger to the crane operator
and for initiating and directing safe movement of the crane and hook load. Recommended
standard hand and radio signals are identified as mentioned overleaf.
HAND SIGNALS:
Fully conversant with the use of signals.
Be placed in the right position.
Check that the load is hooked correctly.
Give the signals clearly
RADIO SIGNALS:
Correct use of radio.
Test the radio communication before starting a lifting operation.
Speak clear and slowly.
Use continuous radio connection during the lifting operation when the load is out of sight
of the crane operator.
Avoid unnecessary use of the radio
Prior to commencement of a lifting operation the signalman shall satisfy himself that loads may
be safely handled. The signalman shall remain in visual or radio contact with the crane operator
at all times and with the slinger at initial and at the final phases of the lift as appropriate.

11.3 INSPECTION OF WIRE ROPE
Wire rope is a structural component of the crane which requires periodic replacement. Initial
dimensional measurement of the rope at the time of installation should be documented in the
crane file and should be referred during subsequent inspection of wire rope.
The owner of the crane shall develop and implement a written policy for wire rope inspection,
lubrication, maintenance and replacement. It shall also include rejection criteria and replacement
schedule considering type of crane, usage, history of maintenance, wire rope manufacturers’
recommendations and crane manufacturers’ recommendations.
11.3.1 INSPECTION
The wire rope inspection programme should be prepared taking into consideration crane type,
frequency of use, wire rope and crane manufacturers’ recommendations.
Visual inspection of wire rope during pre-use and monthly inspection should be performed by
qualified crane operator, while quarterly and annual inspection should be carried out by qualified
inspector. Wire rope inspection items should include, but not be limited to, the following.
1. Reduction of rope diameter below the nominal diameter, or initial wire rope dimensional
measurements, due to wear of outside wires, loss of core support or internal or external
corrosion. Core failure in rotation-resistant rope can be difficult to observe. Typical methods to
check core failure are as follows:
o Diameter measurement; diameter is reduced with core deterioration.
o Length of lay measurement; core failure results in an increase in the lay length.
2. The number of broken outside wires and the concentration of the broken wires. Attention should
be given to valley breaks where the breaks are at the strand to contact points.
3. Worn outside wires.
4. Corroded or broken wires at the end connections. Corroded, cracked, bent, worn, or improperly
applied end connections.
5. Kinking, crushing, cutting, or unstranding.
6. Improper spooling on hoist drum such as:
o strand crushing,
o core protrusion,
o abrasion,
o excessive strand gaps,
“OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”
OISD – RP – 205 Page no. 33
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
o loose and uneven spooling,
o high stranding.
7. Heavy wear and/or broken wires occur in rope sections in contact with certain components of
the crane. Care shall be exercised in inspecting the rope at these points. Inspection shall
include, but not be limited to, the following areas.
o Equalizer sheaves or saddles also referred to as fixed guides or other sheaves.
o End connections including socket or end attachments to running ropes, boom pendants
and other standing ropes.
o Sections of the rope where the rope is continually running over sheaves within the
various hoist systems. This inspection is of particular importance where boom angle and
load block changes are frequent and limited to short distances.
o Crossover and flange points of the rope on the hoist drums.
• The following is the rejection/replacement criteria for wire rope.
The following criteria are based on using the wire rope under maximum load condition, limited
usage can continue until the wire rope is replaced.
1. Running ropes used in the boom hoist:
— Six randomly distributed broken wires within one lay length;
— Three broken wires in one strand within one lay length.
2. Running ropes of rotation-resistant construction used in the main or auxiliary hoist:
— Four randomly distributed broken wires within 30 rope diameters;
— Two broken wires in one strand within six rope diameters.
3. Standing ropes such as boom pendants:
— Three broken wires within one lay length;
— Two broken wires at the end connection.
4. One valley (where strand to strand contact occurs) break can indicate internal rope damage
requiring close inspection of this section of the rope. When one or more valley breaks are found
in one lay length the rope should be retired.
5. The rope construction has been distorted by kinking, crushing, or other distortional damage.
6. There is evidence of heat damage from any source (i.e. engine exhaust, flare towers, stress
corrosion cracking, etc.). Heat can be generated by passing a rope over a frozen or non-turning
“OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”
OISD – RP – 205 Page no. 34
RECOMMENDED PRACTICE FOR CRANE OPERATIONS, MAINTENANCE & TESTING (FOR UPSTREAM)
sheave, contact with structural members of the crane, improperly grounded welding leads or
lightning strikes.
7. Reductions for the rope diameter, from initial wire rope dimensional measurements, in a
nonworking area (an area away from the sheaves) compared to the lowest diameter of rope
measured in three working areas (areas where the rope regularly goes over a sheave) of more
than the following is observed:
— 3/64 in. (0.047 in.) (1.2 mm) for diameters up to and including 3/4 in. (19.1 mm);
— 1/16 in. (0.062 in.) (1.6 mm) for diameters of 7/8 in. to 11/8 in. (22.2 mm to 28.6 mm);
— 3/32 in. (0.093 in.) (0.8 mm) for diameter of 11/4 in. to 1 1/2 in. (31.8 mm to 38.1 mm);
— For rope diameters greater than 11/2 in., a 5 % diameter loss from baseline measurement.
8. Increase in the length of an individual rope lay is observed. This increase in lay length and
accompanying reduction in diameter can be caused by failure of the core. This can occur more
readily in ropes or rotation-resistant construction.
9. Corrosion that causes pitting to the surface of individual wires is cause for rope replacement.
For further details, please refer OISD-STD-187, API-RP-2D, or ASME-B-30.5
