Scope of Application

These Guidelines contain technical fundamentals on corrosion and the rules applying to corrosion protection on ships, structural parts, components and structures under maritime environmental and application conditions.

Under the condition that the corresponding boundary conditions are observed, they can also be applied to other systems, structural parts and components.

These Guidelines are intended to supplement the GL Rules for Hull Structures (I-1-1), Section 35 and the GL Rules for Coating of Ballast Water Tanks (VI-10- 1) and for Corrosion Protection of Crude Oil Cargo Tanks (VI-10-3) which are limited to only those aspects which are imperative from the classificatory point of view and which shall always be complied with for the construction of ships with GL Class.

National or international provisions and rules are to be observed in addition.

However, this does not release the operators and designers from the obligation to assess properly the special features of each particular system, structural part or component and to consider the relevant corrosion hazard. In particular, the corrosion protection measures which are applied, their maintenance and the servicing activities shall be coordinated to suit the component or the structure and also the specified lifetime.

In designing the corrosion protection, the specific contractual conditions and agreements between the purchaser and the manufacturer shall always be taken into account.

For the design of the corrosion protection, the relevant normative references shall also be considered. Upon request, GL can act in an advisory capacity.
