Annotation

General

This standard is concerned with the production and furnishing of offshore fibre ropes for designated service and that the offshore fibre rope continues to be fit for the designated service whilst it is being used.

It provides requirements for documentation and a scheme for DNV GL certification of fibre ropes for designated offshore service.

This standard is intended to be used as reference for contracts between parties and it reflects the role responsibilities involved with deliveries and operations with offshore fibre ropes.

Materials

This standard covers offshore fibre ropes that are manufactured using aramid, polyester, HMPE, LCP, or polyamide (nylon) load-bearing yarn materials.

Other load-bearing yarn materials than those stated, including combinations, may be considered on a caseby- case basis. Appropriate technology qualification shall be performed in order to determine acceptance criteria and limits.

Rope construction

Information about types of offshore fibre ropes is provided in DNVGL-RP-E305.

Guidance note:

Offshore fibre ropes may be manufactured with a braided or helical arrangement of the strands (construction). The built-in twist of the strands depends on the production method. A bundle of many parallel, load-bearing elements with an external jacket may also be used. Those parallel elements may be braided or helical subropes, or large (assembled) yarns.
