.... As the low frequency response is a resonant phenomenon, it may only be predicted if adequate knowledge is available concerning low frequency damping. During low frequency excitation, wave drift forces are varying with the change of speed of the floating body, and this variation of the mean drift force can...

... ABSTRACT The computation of low frequency mooring forces on a tanker exposed to survival conditions requires knowledge of the hydrodynamic excitation and reaction forces. The low frequency excitation is caused by wave drift forces. The reaction forces on the tanker are a combination of added...

..., viscous damping and wave drift damping on the hull. For this purpose surge decay tests are performed with the model of ship-type floating production system in horizontal mooring and catenary mooring in still water, and also with horizontal mooring in regular waves. Measured dampings are compared...

... in a simplified three-dimensional model for determining drift forces. That technique is extended further by inclusion of forward speed effects to allow determination of the additional linear wave drift damping term. Comparison of the theoretical results with model test data demonstrates the utility of the method...
