MANOEUVRING SIMULATION OF A TANKER MOORED IN A STEADY CURRENT INCLUDING HYDRODYNAMIC MEMORY EFFECTS AND STABILITY ANALYSIS

A previously validated mathematical model suitable for the simulation of slow-moving large ships is extended to include certain memory effects in the hydrodynamic forces and used to compute autonomous motions of a tanker anchored or moored in a steady current. The memory effects considered are due to the waves generated by the moving ship as predicted by linear three- dimensional potential theory, while the stability of the equilibrium states is determined by examining the eigenvalues of the locally linearized dynamic equations.
