Investigation about wave profile effects on ship stability

Abstract

The possible influence of wave profile on ship righting arm is among the stability issues of failure addressed by the recent activity at IMO. The present paper is mainly focused on the so called “pure loss of stability”, a dangerous phenomenon that can occur for specific conditions in following seas. In the paper, the development of a computational tool is described, able to evaluate the influence of wave profile on ship metacentric height and righting arms, giving the possibility to investigate different ship geometries and loading conditions in relation with wave profiles in terms of different lengths and steepness. The tool will be applied to ship typologies that in principles can be more disposed to pure loss of stability i.e a modern destroyer type hull form with tumblehome topside, a Ro-Ro passenger ferry, and a container ship. For comparison purposes also in principle not vulnerable ships like a bulk carrier and a tanker will be investigate
