Dynamics of a Rigid Ship

Research output: Book/ReportCommissioned report

Abstract

The approach to ship dynamics presented in the book makes it possible to deal with the seemingly different problems such as ship maneuvering, sea-keeping and dynamic stability using the same unified mathematical model. Motion dynamics of a ship regarded as a rigid body in a general motion with six-degree-of-freedom is considered. The relation of non-linearities of the applied sub-models to the physical phenomena associated with the ship behavior is discussed. Surface wave theory is presented. Non-linearities associated with surface waves are discussed. Realization of the unified mathematical model in a form of simulation tool, called LaiDyn, is discussed and examples of its applications are shown. Mathematical model for assessing internal hull girder loads is presented briefly. An un-symmetry of internal loads, visible as different maximum values of sagging and hogging, is presented and the origins of it are discussed.
