Ships and marine technology — Mooring tensioner for floating offshore wind turbine ISO/PWI 24164.2

Scope

This document specifies the requirements for the definition, type, materials, design, coating and corrosion protection, use and maintenance of mooring tensioner intended for floating offshore wind turbine.The tensioner is an important component for mooring system of floating wind turbine with low cost and small footprint. It provides pre-tensioning and self locking for the mooring lines. The tensioner can be installed at the top or in the middle of the mooring leg. The parts of tensioner are made by casting, welding or forging as specified in this standard. The pre-tension load during installation and breaking load of the mooring line shall be considered for different parts of the tensioner during design.
Additionally, the tensioner shall be tested and inspected for mechanical properties, proof load, surface quality and functions. The requirements on coating, installation and maintenance are also specified in the standard.
