Fully three-dimensional ship seakeeping computations with a surge-corrected Rankine panel method

摘要

A 3-d seakeeping code uses first-order Rankine panels with special numerical integration on the ship's hull and Rankine point source clusters above the free surface. The code computes the motions of the ship in regular waves of small height (linearized). The steady flow is captured without simplification by solving the fully nonlinear wave-resistance problem first. A special treatment of the surge motion con- siders the influence of periodic quantities on thrust and resis- tance, and improves surge motion predictions.
