Corrosion protection of ships
|Publication Date:||1 May 2017|
The aim of this guideline is to indicate different recognised methods for corrosion protection and surface preparation of ships and systems installed on ships, with emphasis on tanks and holds. For ballast tanks, double side skin space of bulk carriers, void space, cargo oil tanks and permanent means of access, this guideline refers to the IMO and IACS regulations, resolutions, circulars and interpretations.
Use of cathodic protection is recommended in combination with coating on surfaces submerged in seawater, e.g. sacrificial anodes in ballast tanks.
The guideline is not mandatory for classification use but for assisting in the selection of effective corrosion protection systems by shipyards and owners.
Definitions and terms, properties and standards for protective coatings, a check list for coating inspectors, materials and corrosion resistance, surface preparation of steel, and coating condition evaluation on existing ships are briefly reviewed.
