Numerical and Experimental Transient Tests for Ship Seakeeping

A potential flow model for linearized ship seakeeping in time domain is presented. The numerical algorithm is briefly sketched. The transient test technique, based on the interaction of a mathematical wave packet with the advancing ship, is numerically simulated and allow to recover the efficiency of frequency domain models. Solutions are presented for a frigate, a container-ship and a mathematical tri-hull. A set of experiments, also of transient type, have been performed to support the numerical findings.
