The computational results are encouraging in that the response amplitude operators (RAOs) of sway and roll motion show good agreement with the data measured in incident regular waves with various wave lengths. In addition, the hydrodynamic forces acting on the body and its tanks are analyzed, and the effects...

... tank. The potentiometer was used to measure the roll and pitch motion of the ship. Two load cells were attached between the ship bottom and the heave rod to measure the wave forces acting on the ship hull. Firstly, the pitch RAO and added resistance without the LNG tank are compared with the results...
