1.1<\/b> General<\/p>\n

This International Standard defines the means to be used to ensure that cathodic protection is efficiently 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.<\/p>\n

1.2<\/b> Structures<\/p>\n

This International Standard specifies 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 specifies cathodic protection of the submerged areas of appurtenances, such as chains attached to the structure, when these are not electrically isolated from the structure.<\/p>\n

This International Standard is to be used in respect of cathodic protection systems where the anodes are exposed to water or saline mud. For 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 are defined in EN 12954, the anodes being exposed to soils.<\/p>\n

This International Standard does not cover the cathodic protection of fixed or floating offshore structures (including offshore loading buoys), submarine pipelines or ships.<\/p>\n

This International 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.<\/p>\n

1.3<\/b> Materials<\/p>\n

This International Standard covers the cathodic protection of structures fabricated principally from bare or coated carbon and carbon manganese steels.<\/p>\n

As some parts of the structure may be made of metallic materials other than carbon steels, the cathodic protection system should be designed to ensure that there is a complete control over any galvanic coupling and minimize risks due to hydrogen embrittlement or hydrogen-induced cracking (see ISO 12473).<\/p>\n

This International Standard does not address steel reinforced concrete structures (see ISO 12696).<\/p>\n

1.4<\/b> Environment<\/p>\n

This International Standard is applicable to the whole submerged zone in seawater, brackish waters and saline mud and related buried areas which can normally be found in port, harbour, coastal and flood defence installations wherever these structures are fixed or floating.<\/p>\n

For surfaces which are alternately immersed and exposed to the atmosphere, the cathodic protection is only effective when the immersion time is long enough for the steel to become polarized. Typically, effective cathodic protection is achieved for all surfaces below mid tide.<\/p>\n

For structures such as sheet steel and tubular steel piles that are driven into the sea bed or those that are partially buried or covered in mud, this International Standard is also applicable to the surfaces buried, driven and exposed to mud which are intended to receive cathodic protection along with surfaces immersed in water.<\/p>\n

Cathodic protection may also be applied to the rear faces of sheet steel piled walls and the internal surfaces of filled caissons. Cathodic protection of such surfaces is specified by EN 12954.<\/p>\n

This International Standard is applicable to those structures which are, or may be in the future, affected by \u201cAccelerated Low Water Corrosion\u201d (ALWC) and other more general forms of microbial corrosion (MIC) or other forms of so-called \u201cconcentrated corrosion\u201d associated with galvanic couples, differential aeration and other local corrosion influencing parameters<\/p>\n

1.5<\/b> Safety and environment protection<\/p>\n

This International Standard does not address safety and environmental protection aspects associated with cathodic protection to which national or international regulations apply.<\/p>\n
