Summary: A finite element tool has been developed to design and investigate a multi-hullcomposite ship structure, and a hybrid hull of identical length and beam. Hybrid hullstructure is assembled by Titanium alloy (Ti-6Al-4V) frame and sandwich compositepanels. Wave loads and slamming loads acting on both hull structures have beencalculated according to ABS rules at sea state 5 with a ship velocity of 40 knots.Comparisons of deformations and stresses between two sets of loadings demonstrate thatslamming loads have more detrimental effects on ship structure. Deformation underslamming is almost one order higher than that caused by wave loads. Also, Titaniumframe in hybrid hull significantly reduces both deformation and stresses when comparedto composite hull due to enhancement of in plane strength and stiffness of the hull. A 73m long hybrid hull has also been investigated under wave and slamming loads in timedomain for dynamic analysis.
