This document specifies the requirements for the external and internal cathodic protection for offshore wind farm structures. It is applicable for structures and appurtenances in contact with seawater or seabed environments. This document addresses: \u2014    design and implementation of cathodic protection systems for new steel structures; \u2014    assessment of residual life of existing cathodic protection systems; \u2014    design and implementation of retrofit cathodic protection systems for improvement of the protection level or for life extension of the protection; \u2014    inspection and performance monitoring of cathodic protection systems installed on existing structures, and \u2014    guidance on cathodic protection of reinforced concrete structures.<\/p>\n
