A naval perspective on ship stability

Abstract

From a naval perspective, three areas have been identified as critical for examining the performance of vessels in extreme seas: the physics of large-amplitude motions; verification, validation and accreditation (VV&A) of tools for these conditions; and performance-based criteria. In the physics of large-amplitude motions, three topics are most important: hydrodynamic forces, maneuvering in waves, and large-amplitude roll damping. In the VV&A arena, the challenge remains for performing this function for extreme seas conditions, where linear concepts such as response amplitude operators are not applicable. The challenge of performance-based criteria results from the fact that it is on the leading edge of our knowledge base. © Springer Science+Business Media B.V. 2011.
