ISO - 20313

Ships and marine technology - Cathodic protection of ships

active, Most Current
Organization: ISO
Publication Date: 1 January 2018
Status: active
Page Count: 64
ICS Code (Hulls and their structure elements): 47.020.10
scope:

This document specifies protection criteria, and makes recommendations for design and specifications for both impressed current and galvanic anode cathodic protection systems for ships. Cathodic protection of external hull and ballast tanks are included.

This document is applicable to the immersed sections of hulls and tanks containing seawater for ships, boats, and other self-propelled floating vessels. It includes fixtures generally encountered on ship hulls such as:

- rudders;

- propellers;

- shafts;

- stabilizers;

- thrusters;

- sea chests;

- water intakes (up to the first valve).

It does not cover protection of floating structures that are not self-propelled.

This document is applicable to the cathodic protection of ship hulls fabricated principally from carbon manganese or low-alloy steels including fixtures of other ferrous or non-ferrous alloys such as stainless steels and copper alloys, etc.

This document is applicable to both coated and bare hulls and tanks; most hulls and tank internals are coated.

This document is not applicable to the cathodic protection of hulls principally made of other materials such as aluminium alloys, stainless steels or concrete.

This document is applicable to the hull and fixtures in seawater and all waters which could be encountered during a ship's world-wide deployment.
