Tackling the challenge of hydro-structural response


Evaluating the wave induced, structural response is of fundamental importance in the process of the design verification of a ship’s structural integrity. CRS is performing state-of-the-art research in this field.

24 report


ydro-structure interactions include a variety of complex physical phenomena which should be taken


into account from both the quasi-static (low frequency wave loading), and fully dynamic (springing, whipping…) points of view. The most critical part of the problem is related to the efficient modelling of the seakeeping behaviour, which should


include both the global (wave diffraction and radiation) and the local (slamming, sloshing, green water …) effects for a ship sailing with arbitrary speed in heavy seas. Due to the extreme complexity of the different phenomena involved, and in spite of all the past and recent developments, all the details of the hydro-structure interactions are still not fully mastered today.
