Abnormal wave encounters can result in significant damage to, or loss of, a vessel. There is a need to identify the risks to a vessel when encountering abnormal waves, from a structural viewpoint. This paper approaches this need, by carrying out an experimental investigation of rigid body motions and global wave-induced loads experienced by a ship in abnormal waves and using the findings to validate a two-dimensional linear hydroelasticity model. Experiments were conducted using a segmented, flexible backbone model in regular and irregular (random and abnormal) sea states, at forward speed. Abnormal sea states were generated using a previously developed optimisation technique. Measurements were made of symmetric motions and the vertical bending moment at various locations along the ship. The influence of slamming on the severity of abnormal wave encounters is discussed.

Abstract

Abnormal wave encounters can result in significant damage to, or loss of, a vessel. There is a need to identify the risks to a vessel when encountering abnormal waves, from a structural viewpoint. This paper approaches this need, by carrying out an experimental investigation of rigid body motions and global wave-induced loads experienced by a ship in abnormal waves and using the findings to validate a two-dimensional linear hydroelasticity model. Experiments were conducted using a segmented, flexible backbone model in regular and irregular (random and abnormal) sea states, at forward speed. Abnormal sea states were generated using a previously developed optimisation technique. Measurements were made of symmetric motions and the vertical bending moment at various locations along the ship. The influence of slamming on the severity of abnormal wave encounters is discussed.
