Omfang

1.1 General This European Standard defines the means to be used to ensure that adequate cathodic protection is applied to the immersed and driven/buried metallic external surfaces of steel port, harbour, coastal and flood defence installations and appurtenances in seawater and saline mud to provide protection from corrosion. 1.2 Structures This European Standard defines cathodic protection of fixed and floating port and harbour structures. This includes piers, jetties, dolphins (mooring and berthing), sheet or tubular piling, pontoons, buoys, floating docks, lock and sluice gates. It also defines cathodic protection of the submerged areas of appurtenances, such as chains attached to the structure, when these are not electrically isolated from the structure. It defines the cathodic protection of the buried areas, typically in soil or sand filled areas behind piled walls or within filled caissons which may be significantly affected by corrosion. Specific cathodic protection design and operation requirements for buried applications are defined in EN 12954. Typically this European Standard will be used in respect of cathodic protection systems where the anodes are in water or saline mud; EN 12954 will normally be used if anodes are onshore. It does not cover the cathodic protection of fixed or floating offshore structures (including offshore loading buoys), submarine pipelines or ships. This European Standard does not include the internal protection of surfaces of any components such as ballast tanks, internals of floating structures flooded compartments of lock and sluice gates or the internals of tubular steel piles. 1.3 Materials This European Standard covers the cathodic protection of structures fabricated principally from bare or coated carbon and carbon manganese steels.
