Recently, the spar platform concept develops quickly in the offshore oil and gas exploitations, especially in deep and ultra-deep water, owing to its benign motion performance, excellent stability and adaptation to wi...
A time domain Kelvin source high order panel method based on NURBS is developed and applied to solve the unsteady wave making problems. Numerical results of instant wave resistance and free surface elevation are pr...
Based on the Laplace transform an ordinary differential equation for the two-dimensional time-domain free-surface Green function in ship hydrodynamics is presented. The results for 2D Green function and its horizontal...
Time-domain analysis is used to predict wave loading and motion responses for a ship travelling at a constant speed in regular oblique waves. The combined diffraction and radiation perturbations, caused by the steady ...
In this paper, based on transient free-surface Green function and panel method, accurate wave exciting forces and moments acting on an arbitrary 3-D body moving at constant forward speed are given by using a time doma...
