This European Standard covers the cathodic protection of the external surface of offshore floating structures which are static during their usual operating conditions. This essentially includes: barges, jack-ups, semi-submersible platforms, storage tankers, buoys, etc.

It also covers the submerged areas of appurtenances, such as chains, attached to the structure, when these are not electrically isolated from the structure.

It does not cover the cathodic protection of ships, fixed offshore structures, elongated structures (pipelines, cables) or harbour installations, which are covered by other standards.

This European Standard concerns only the cathodic protection of external surfaces immersed in sea water, including sea chests and water intakes up to the first valve.

This European Standard does not include the internal protection of surfaces of any components such as ballast tanks and hull internals of floating structures.
