1) Wire ropes used in fore runner and bottom legs of lifting slings assembled by Aberdeen Lifting Services Ltd. to be 6 x 19 or 6 x 36, Fibre Core (FC) or Independent Wire Rope Core (IWRC), with wire rope grades 1770 N/mm² and 1960 N/mm².

2) Only considered part of sling if captive (i.e. can not be removed after assembly of sling).

3) Ferrules / sleeves: According to EN 13411-3

4) Thimbles: Federal Specification FF-T-276b, Type III, or equivalent.

Components should be delivered with the following certificates:

- Master Links, Quad assemblies and Shackles:

Certificates based on DNV Type Approval.

- Wire Ropes:

To be supplied with traceable material certificates according to EN 10204, inspection certificate, type 3.1B.

- Thimbles and ferrules:

To be supplied with a material certificate to EN 10204, test report, type 2.2.

Application/Limitation

Lifting sets shall be assembled according to the strength requirements for lifting sets on Offshore Containers as described in DNV 2.7-1 Offshore Containers, Chapter 8. The angle of the sling legs from vertical should be taken into account when choosing slings. This angle should normally be 45°, but smaller angles can be used.

Special slings, assembled according to the principles described in DNV 2.7-1 Offshore Containers, Chapter 8 and Appendix E, are also covered by this Type Approval. However, if unsymmetrical slings are to be assembled, local DNV office are to be contacted for reviewing in each case, unless otherwise is agreed with local DNV office.

Note: The sling leg is not necessarily the weakest part of the lifting set. Master link assemblies selected for slings with legs at 45˚ may not be suitable for slings with a smaller angle.

For each delivered drum of wire rope, a test leg with one eye in each end to be prepared and tested to breaking. A reference should be made to the wire drum test certificate in each sling set certificate where that wire is used.

All production testing to be agreed with local DNV office, and all products manufactured according to this TA shall be inspected by a DNV surveyor, and in addition the DNV surveyor shall witness the production testing and issue certificates for each Lifting Set or batch of Lifting Sets, according to DNV 2.7-1 Offshore Containers, Chapter 8 and Appendix K.

Alternatively, based on a Manufacturing Survey Arrangement (MSA) with DNV, the manufacturer may issue certificates for all slings according to DNV 2.7-1 Offshore Containers, Annex 1.

For replacing and repair of lifting sets on Offshore Containers certified according to the 1989 and 1995 editions of DNV 2.7-1 Offshore Containers, please follow the procedure as given in Appendix 1 of this Type Approval Certificate.

Type Approval documentation

Marking of product

Slings are to be marked with certification tag according to DNV 2.7-1 Offshore Containers, Chapter 8, as shown below:



Example of identification tag for a
chain sling - Front

1) CE mark and Reference to this Standard for Certification

2) 4 legs of 13 mm, 1 forerunner of 22 mm (example)

3) Manufacturer's mark

4) Sling angle

5) Shackle size

6) WLL



Example of identification tag for a
chain sling - Back

1) Certificate number (and unique identification number if applicable)

2) Column 1: inspectors mark, inspection suffix and date of periodic inspections (shall be of format YY-MM-DD)

3) Column 2: shackle ID number

4) The owner's name may optionally be included

For wire rope slings, the tag shall be round.

Certificate retention survey

As agreed with the local DNV office, but intervals not to exceed 4 years.

END OF CERTIFICATE

Appendix 1

On offshore containers certified according to the 1989 and 1995 editions of DNV 2.7-1 the dimensioning of shackles was based on the breaking strength. On some containers both the diameter of the shackle pin hole and the location of the padeye may not allow the use of larger shackles.

Where existing pad eye on the Offshore Container does not fit with the required shackle dimension, application of shackles should be as follows:

Minimum required breaking force, BF_min (kN), for shackles should be calculated according to the following formula:



where:

R = Rating

g = Standard acceleration of gravity (~9,81 m/s²)

n = Number of legs

v = The angle of sling leg from vertical

SF = Safety Factor (table 1), between given values the SF can be found by linear interpolation

The shackle should have a BF ≥ BF_min, where the applicable BF, according to DNV 2.7-1 (1995), can be found in Appendix 2 in DNV Type Approval Certificates for shackles, where applicable.

DNV Type Approval certificates can be found under "Approved Services" on DNV's website http://exchange.dnv.com/exchangemenu/taskmanager.asp

For wire rope lifting sets, if not possible to fit the shackle in the wire leg eye, it is acceptable to fit an intermediate link between the leg and the shackle, with a WLL ≥ WLL_min as calculated for the leg according to DNV 2.7-1 Offshore Containers, chapter 8, see figure 1.

Rating, R (kg)	Safety Factor (SF)
≤ 6000	8,0
10000	6,8
15000	5,8
20000	5,2
25000	5,0
