The document outlines best practices for lifting and hoisting in the oil and gas industry, emphasizing the importance of risk assessments, lift plans, and the selection of competent personnel for various types of lifts. It details the necessary safety measures and procedures for routine, non-routine, and complex lifting operations, including the correct use of wire rope slings and the application of enhancement factors for load limits. A strong emphasis is placed on maintaining a 'hands-free' culture to reduce hand and finger injuries during lifting operations.

19. Maintain a Hands Away philosophy
Hand and finger injuries continue to be the most
common incidents at Weatherford
Almost everything we do involves our hands and
fingers, our exposure is significant
To reduce the risks, keep your hands off loads!
• Use tag lines or push/pull bars to control loads
We are not permitted to touch a load while it is in
motion or under tension

20. HOW TO SELECT CORRECT WIRE ROPE SLINGS
High Risk Most common non compliance!
Most of the contractor are using wire rope slings for lifting their equipment to transport
onshore and offshore premises, however it has been observed that the capacity of the
wire rope slings being used for the particular equipment, has no Enhancement factor to
compensate dynamic factors during lifts.
What is Enhancement factor?
The enhancement factor is higher degree selection of slings for containers, because
containers are subject to the most severe dynamic amplification due to dynamic
amplification that will be experienced in offshore lifting in adverse weather, sea states,
crane behavior and operator skill.

21. HOW TO SELECT CORRECT WIRE ROPE SLINGS
What is Right?
The minimum working load limit, of the lifting sets for offshore containers shall be
determined for the lifting set and each of its components according to
enhancement factor , and the rating of a container is multiplied by an
enhancement factor to give an enhanced requirement for the working load limit
of the sling as per the standard. If the equipments is designed and fabricated as
per the relevant standard of BS EN 12079-1-2006 or DNV-2.7.1
OR
All lifting equipment and lifting gears used in the lifting process shall be rated at
30% or more above the maximum load to be lifted as per our Shell Lifting and
Hoisting standard..

22. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Simple Guide of sling selection.
Slings can be selected in two different method, and the methods are as follows:
1. Trigonometric method
2. Uniform method
1. Trigonometric method:
The trigonometric method is provides for progressive reductions in the working load
limit as the angle between the sling legs increase.
It assumes the operative is trained in the assessment of angle and requires the display
of a chart showing the working load limits which apply at various angle.
It strongly recommended that this method should only be used for slings designed for
a single purpose only.

23. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Single leg sling = 1 x WLL of single leg
Two leg Sling = 2 x WLL of single leg x Cos
Three leg = 3 x WLL of single leg x Cos
Four leg Sling = 4 x WLL of single leg X cos
In other cases the WLL for a four leg sling will be the same as for a three leg sling.

24. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Example: 1
Single wire rope capacity of 26 mm = 7.8 t (This could vary based on minimum Breaking load)
To obtained the capacity of two leg sling by using trigonometric method
capacity of two leg = 2 x WLL of single leg x Cos
= 2 x 7.8 x cos (Which is the angle between the legs)
= 2 x 7.8 x cos 30°
= 2 x 7.8 x 0.866 ( Cos 30°= 0.866)
Therefore the total capacity of the two leg slings will be = 2 x 7.8 x 0.866 =13.5 t
NOTE: Please note that this method should only be used for slings designed for a
single purpose only

25. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Example: 2
Single wire rope capacity of 26 mm = 7.8 t (This could vary based on minimum Breaking load)
To obtained the capacity of three leg slings by using Trigonometric method
Capacity of three leg = 3 x WLL of single leg x Cos
= 3 x 7.8 x cos (Which is the angle between the legs)
= 3 x 7.8 x cos 30°
= 3 x 7.8 x 0.866 ( Cos 30°= 0.866)
Therefore the total capacity of the three leg slings will be = 3 x 7.8 x 0.866 =20.26 t
NOTE: Please note that this method should only be used for slings designed for a
single purpose only

26. HOW TO SELECT CORRECT WIRE ROPE SLINGS
2. Uniform method
The uniform method is the simple option, having inherent safety advantages, permitting
only one working load limit to the angle to vertical legs maximum of 0-45°
Single leg sling = 1 x WLL of single leg
Example-1
Single wire rope capacity of 28 mm = 9.0 t (This could vary based on minimum Breaking load)
To obtained the capacity of two leg slings by using Uniform Method
Capacity of two leg = WLL of single leg x 1.4 (Mode factor)
= 9.0 x 1.4 (Which is the angle to the vertical legs cos45°+ cos45°= 0.707 +0.707 =1.4)
= 9.0 x1.4 = 12.6 t
Therefore the total capacity of
the two leg slings will be = 9.0 x 1.4 =12.6 t

27. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Example-2
Single wire rope capacity of 28 mm = 9.0 t (This could vary based on minimum Breaking load)
To obtained the capacity of Three leg slings by using Uniform Method
Capacity of Three leg = WLL of single leg x 2.1 (Mode factor)
= 9.0 x 2.1 (Which is the angle to the vertical legs cos45°+ cos45°= 0.707 +0.707 +0.707=2.1)
= 9.0 x 2.1 = 18.9 t……say =19 t
Therefore the total capacity of
the three leg slings will be = 9.0 x 2.1 =19.0 t

28. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Example-3
Single wire rope capacity of 28 mm = 9.0 t
(This could vary based on minimum Breaking load)
To obtained the capacity of Four leg slings by using Uniform Method
Capacity of Four leg = WLL of single leg x 2.1 (Mode factor)
= 9.0 x 2.1 (Which is the angle to the vertical legs cos45°+ cos45°= 0.707 +0.707 +0.707=2.1)
= 9.0 x 2.1 = 18.9 t……say =19 t
Therefore the total capacity of
the four leg slings will be = 9.0 x 2.1 =19.0 t
Note: 4th leg is only retardant sling, hence 3 4 legs remain same capacity
In other cases the WLL for a four leg sling will be the same as for a three leg sling.

29. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Please refer the below chart as per BS EN 13414-1-2003, which is uniform method
of selection of the slings steel cored rope of classes 6x19, 6x36 and 8 x 36 and
having ferrule-secured eye terminations;

30. HOW TO SELECT CORRECT WIRE ROPE SLINGS
Please refer the below chart as per BS EN 12079-2-2006, and DNV 2.7.1,
which has enhancement factor for selection of the slings .
