Validation of the Standard Ship Motion Program, SMP: Improved Roll Damping Prediction

Abstract

Refinement in calculating the roll damping characteristics of surface ships, particularly in the speed-dependent lift damping terms, has significantly improved the prediction of lateral ship motions. Incorporation of these refinements into the new revised ship motion computer program has greatly enhanced the accuracy and usefulness of the program. Validation of the roll damping computations is presented in this document through the comparison of computer-predicted damping with model test data for a number of ships. Relatively good agreement is found between the analytical and experimental results. (Author)
