Scope
This document specifies the requirements for external and internal cathodic protection of offshore wind farm structures, and is applicable to structures and accessories that come into contact with seawater or the seabed environment.
This document covers:
-- Design and implementation of cathodic protection systems for new steel structures;
-- Assessment of the remaining service life of existing cathodic protection systems;
-- Design and implementation of cathodic protection system updates to enhance protection levels or extend protection lifespan;
-- Inspection and performance monitoring of cathodic protection systems installed on existing structures;
-- Guidelines for cathodic protection of reinforced concrete structures.
