EFFECT OF CURRENT AND WAVES ON THE DAMPING COEFFICIENT OF A MOORED TANKER

It is described how a model test was performed on a 67,000 dwt tanker moored in head seas fore and aft with linear springs, in combinations of regular waves and current. At the initiation of each test run, the vessel was displaced and released from its equilibrium position. The resulting motions and line loads were recorded. The data was analyzed to determine the effects of wave amplitude and frequency, as well as that of the current, on the damping factor and the added mass coefficient. The first order responses and steady drift loads resulting from the regular waves are also presented.
