Cathodic protection of harbour installations (ISO 13174:2012)

ISO 13174:2012 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.
ISO 13174:2012 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.
ISO 13174:2012 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.
ISO 13174:2012 does not cover the cathodic protection of fixed or floating offshore structures (including offshore loading buoys), submarine pipelines or ships.
ISO 13174:2012 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.
ISO 13174:2012 covers the cathodic protection of structures fabricated principally from bare or coated carbon and carbon manganese steels.
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 ).
ISO 13174:2012 does not address steel reinforced concrete structures (see EN 12696).
ISO 13174:2012 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.
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.
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, ISO 13174:2012 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.
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.

Kathodischer Korrosionsschutz für Hafenbauten (ISO 13174:2012)

1.1   Allgemeines
Die vorliegende Europäische Norm definiert die Möglichkeiten, die zu verwenden sind, um sicherzustellen, dass genügend kathodischer Korrosionsschutz an die unter Wasser befindlichen und eingerammten/bodenbedeckten metallenen Außenflächen von stählernen Hafen-, Küsten- und Hochwasserschutzanlagen und Zubehör in Meerwasser und salzhaltigem Schlick angewendet wird, um Schutz vor Korrosion zu bieten.
1.2   Konstruktionen
Diese Europäische Norm definiert den kathodischen Korrosionsschutz von ortsfesten und schwimmenden Hafenkonstruktionen. Hierzu zählen Piers, Anleger, Duckdalben (Festmachen und Anlegen), Wände aus Spundbohlen oder Rohrpfählen, Pontons, Bojen, Schwimmdocks, Schleusentore und Wehrverschlüsse.
Sie definiert den kathodischen Korrosionsschutz von den eingetauchten Flächen von Zubehör wie beispielsweise Ketten, die an den Konstruktionen befestigt sind, jedoch nicht elektrisch von der Konstruktion isoliert sind.
Sie definiert den kathodischen Korrosionsschutz der erdbedeckten Flächen, typischerweise in Erdböden oder mit Sand aufgeschüttete Flächen hinter Pfahlwänden oder innerhalb von gefüllten Senkkästen, die erheblich von Korrosion befallen werden könnten. Spezielle kathodische Korrosionsschutzentwurfs- und Betriebsanforderungen an Anlagen in Böden sind in EN 12954 definiert. Typischerweise wird diese Europäische Norm mit Bezug auf kathodische Korrosionsschutzsysteme verwendet, bei denen sich die Anoden in Wasser oder salzhaltigem Schlick befinden; gewöhnlich wird EN 12954 angewendet, wenn sich die Anoden an Land befinden.
Sie deckt nicht den kathodischen Korrosionsschutz von ortsfesten oder schwimmenden Offshore-Anlagen (einschließlich Offshore-Ladebojen), untermeerischen Rohrleitungen oder Schiffen ab.

Protection cathodique des installations portuaires (ISO 13174:2012)

L'ISO 13174:2012 spécifie les moyens à mettre en ?uvre pour garantir qu'une protection cathodique est appliquée efficacement aux surfaces métalliques externes immergées et battues ou enfouies des installations portuaires, côtières et anti-crue en acier et de leurs parties annexes exposées à l'eau de mer et aux boues marines afin d'assurer leur protection contre la corrosion.
L'ISO 13174:2012 spécifie la protection cathodique des ouvrages portuaires fixes et flottants. Ces ouvrages comprennent les appontements, les jetées, les ducs d'Albe (d'amarrage et d'accostage), les palplanches ou les pieux tubulaires, les pontons, les bouées, les docks flottants, les portes et vannes d'écluses. Elle spécifie également la protection cathodique des surfaces submergées des parties annexes, par exemple les chaînes connectées à l'ouvrage, lorsqu'elles ne sont pas isolées électriquement de l'ouvrage.
L'ISO 13174:2012 doit être utilisée pour les systèmes de protection cathodique dont les anodes se trouvent dans l'eau ou dans les boues marines. Pour les zones enfouies, typiquement dans les remblais en sable ou en terre derrière des rideaux de palplanches battus ou à l'intérieur de caissons de soutènement, qui peuvent être affectées de manière significative par la corrosion, les exigences spécifiques relatives à l'étude et au fonctionnement de la protection cathodique sont définies dans l'EN 12954, les anodes étant exposées aux sols.
L'ISO 13174:2012 n'est pas applicable à la protection cathodique des ouvrages offshore fixes ou flottants (y compris les bouées de chargement offshore), des canalisations sous-marines ou des navires.
L'ISO 13174:2012 n'inclut pas la protection interne des surfaces des composants tels que les ballasts, les surfaces intérieures des compartiments ennoyés des ouvrages flottants, les portes et vannes d'écluses, ou encore les surfaces intérieures des pieux tubulaires en acier.
L'ISO 13174:2012 traite de la protection cathodique des ouvrages réalisés principalement à partir d'aciers au carbone et au carbone-manganèse nus ou revêtus.
Certaines parties de l'ouvrage pouvant être réalisées en matériaux métalliques autres que les aciers au carbone, il convient de concevoir le système de protection cathodique de manière à assurer une parfaite maîtrise de tout couplage galvanique et à réduire au minimum les risques dus à la fragilisation hydrogène ou à la fissuration induite par l'hydrogène (voir l'ISO 12473).
L'ISO 13174:2012 n'est pas applicable aux ouvrages en béton armé (voir l'EN 12696).
L'ISO 13174:2012 est applicable à l'ensemble des zones submergées en eau de mer, en eau saumâtre et dans les boues marines, ainsi qu'aux zones enfouies associées qui font normalement partie des ouvrages, fixes ou flottants, des installations portuaires, côtières et anti-crue.
En ce qui concerne les surfaces qui sont de façon intermittente immergées et exposées à l'atmosphère, la protection cathodique n'est efficace que lorsque le temps d'immersion est suffisamment long pour permettre la polarisation de l'acier. La protection cathodique est généralement efficace pour toutes les surfaces situées sous le niveau moyen des marées.
Pour les ouvrages tels que les rideaux de palplanches et de pieux tubulaires en acier qui sont battus dans le fond marin ou pour ceux qui sont partiellement enfouis ou sont recouverts de vase, l'ISO 13174:2012 est également applicable aux surfaces enfouies, battues et envasées qui vont bénéficier d'une protection cathodique en même
