This recommended practice is meant to supplement structural design standards for offshore steel structures and gives recommendations on how to design a structure against accidental loads.

The following main subjects are covered:

— design philosophy

— ship collisions

— dropped objects

— fire

— explosions

— unintended flooding.

Design against accidental loads are often carried out using advanced methods such as non-linear finite element analyses. Determination of structural capacity by non-linear analyses in general is described in DNV-RP-C208. This recommended practice describes more simplified and tailor-made methods for capacity assessments for accidental events.
