... largely in head wave. The twin-barge motions were quite difference in both amplitude and phase in beam waves, which was caused by the shield effect and the elastic connection. The lash line experienced large forces in beam waves and should be paid attentions. The experimental results will provide valuable...

Paper Number: ISOPE-I-05-029
.... As a conclusion, the agreement between the experimental results and the numerical results is good. The strain of the transverse beam in the beam waves has a high peak, which should be lowered for the realistic design of this concept. It is found that drift forces are not significant except for the frequency...

...). This is particularly evident by considering the IMO Weather Criterion (see IMO Res. A.749 and the underlying theory, Yamagata, 1959). Of course, these approaches cannot describe the last stages of motion leading to capsizing, but it is common opinion that capsize in beam waves is always due to the concurrent action...
