The International Maritime Organisation (IMO) Code of Safety for High Speed Craft (HSC-code) has introduced very strict requirements for the passive fire safety for vessels made of composite materials. This paper summarises the IMO-requirements related to fire reaction and fire resistance for a composite vessel. It is shown that requirements in many cases are much stricter than for conventional vessels. This paper also discusses the relation between different structural materials and structural integrity during a fire. It is shown that sandwich structures can meet the new requirements with little or no extra weight.
