| Research Abstract |
Nowadays the lightering operation in which the crude oil is transferred from a large ship to small one is commonly conducted in worldwide scale. In the case of lightering offshore, the cargo transfer is carried out with the two ships under power which is called as underway transfer. The purpose of this study is to understand the characteristics of hydrodynamic forces acting on those ships and maneuverability of them during the operation. Three topics are included in this study. First, the yawing ability and course stability of the combined ship engaged in underway transfer were discussed based on the results of captive model test in the towing tank and maneuvering simulation. Next, the berthing operation was simulated in consideration of the interaction forces between two ships. The effect of loading condition on the maneuvering motions in berthing was evaluated. Third, the hull to rudder interactions of ships in close proximity were also studied both in deep and shallow water.
