“Dynamics of a Rigid Ship”: a freely available book on nonlinear ship dynamics from Prof. Jerzy Matusiak - Aalto University (Finland)

A new book on nonlinear ship dynamics, written by Prof. Jerzy Matusiak (Aalto University - Finland) and entitled “Dynamics of a Rigid Ship”, has recently been published and can be freely downloaded from:


The book is primarily meant as textbook of the course “Ship Dynamics” provided for the students of Maritime Engineering of Aalto University.

This textbook is a result of the work started in 1996 when the author joined a very interesting, newly formed Specialist Committee working on Ship Stability within the International Towing Tank Conference (ITTC). Thanks to this group of international enthusiastic scholars in the field, it became clear for the author that both the research and the rules’ development in the field of ship stability will proceed in the direction of including ship dynamics. Moreover, this development will require sophisticated mathematical models of ship dynamics, to be verified and thoroughly validated, based on the first principles and taking realistically into account the environmental, often very hostile, conditions.

The approach to ship dynamics presented in the book makes it possible to deal with the seemingly different problems such as ship maneouvring, 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 behaviour 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.
