ANALYSIS OF SINGLE POINT MOORED TANKER USING MANOEUVRING HYDRODYNAMIC MODEL

This paper deals with the dynamic behaviour of the Single Point Mooring System (SPM) of moored vessels considering the influence of environmental forces as well as shallow water effects. A nonlinear mathematical model is developed for the simulation of low speed ship manoeuvres (Takashina, 1986) is extended to study the behaviour of a tanker moored to a single buoy in comparison with Obokata's model (1987). A large number of tanker motion simulations were carried out both for deep and shallow water and different environmental conditions. The influence of the system parameters shown by the study is, in general, in good agreement with those obtained by traditional SPM system analysis.
