Ships are more and more large, fast, cost-effective, optimised. More and more severe weather conditions have to be faced. Regulations become more and more constraining. Offshore developments involve more and more complex and large systems and vessels in very deep or very shallow waters. Here are the challenges that the naval and offshore hydrodynamics have to cope with.

The international scientific cooperation supported by the Industry is quite successful in taking up these challenges thanks to medium and long term research programmes that include the development of new theoretical formulations and new numerical tools, as well as there validation through extensive experimental campaigns.

This paper summarises the challenges and developments in which the authors are very active: second-order wave loadings, the global structural response of large ships to waves and impacts, the parametric roll and the response of the tanks of large LNG carriers to the sloshing impacts.
