Abstract
In this study, nonlinear roll motion of a heavy lift vessel was investigated experimentally. The model test of a heavy lift vessel transporting a wide offshore structure was carried out in Ocean Engineering Basin of KRISO. A series of regular wave tests were performed in order to study the motion response of the heavy lift vessel. Four different wave heights in beam sea were considered. It is clearly observed that the overhung part of the superstructure was submerged in water under the specific wave conditions. This causes periodic wave-in-deck impact and the motion response of the vessel is significantly affected. Discussions were made on the characteristics of nonlinear roll responses of the heavy lift vessel in waves.ar wave tests were performed in order to study the motion response of the heavy lift vessel.
