LOW-FREQUENCY PHENOMENA ASSOCIATED WITH VESSELS MOORED AT SEA

The influence of the low-frequency-wave-drifting force on the motions of moored vessels and the loads in the mooring system is demonstrated from results of model tests in irregular waves. The origin of the wave drifting force is discussed and methods for calculating the mean drifting force are reviewed; and an existing method using the mean drifting force in regular waves is generalized. Some remarks are added concerning effects that have not been accounted for in existing calculation methods. Graphs and equations show data.
