摘要
A time-domain body exact strip theory is developed to predict maneuvering of a vessel in a seaway. A frame following the instantaneous position of the ship, by translating and rotating in the horizontal plane, is used to set up the boundary value problem (BVP) for the perturbation potentials. A boundary integral technique is used for solving the Laplace equation. Linearized free surface boundary conditions are used for stability and computational efficiency, and exact body boundary conditions are used to capture nonlinear effects. A nonlinear rigid body equation of motion solver is coupled to the hydrodynamic model to predict ship responses. Results are presented for the turning circle maneuver of the containership S-175 in calm water and in the presence of regular waves. The results are compared with available experimental results. The simulations are able to capture general qualitative aspects and overall physics of the problem.
