 N RP 2SM

Annotation

This document applies to synthetic fiber ropes used in the form of taut leg or catenary moorings for both permanent and temporary offshore installations such as:

a) monohull-based floating production, storage, and offloading units (FPSOs);

b) monohull-based floating storage units (FSOs, FSUs);

c) monohull or semi-submersible based floating production units (FPUs, FPSs);

d) mobile offshore drilling units (MODUs);

e) spar platforms;

f) catenary anchor leg mooring (CALM) buoys (spread mooring only);

g) mobile offshore units (MOUs, e.g., construction, pipelay, floating accommodation vessels).

This document covers the following aspects of synthetic fiber ropes:

a) design and analysis considerations of mooring system;

b) design criteria for mooring components;

c) rope design;

d) rope specification and testing;

e) rope manufacture and quality assurance;

f) rope handling and installation;

g) in-service inspection and maintenance.
