And this is the third part of volume of the set of Naval Architecture books (Part 1 and Part 2 here), and the present volume is dedicated to the motion of ships in waves and their controllability, i.e. the last two chapters of the course. Taking into account the importance of all recent theoretical and also experimental developments in the subject fields, the authors considered it necessary to fully rewrite the content of both those chapters and to add a great portion of the new material. The chapter on motion in waves covers such the important aspects as the characteristics ocean waves, their origin and propagation, responses of the vessel to the ocean waves, ships in the seaways, derived responses and ship motion control, assessment of the ship seaway performance, various aspects of design, and relevant nomenclature. The chapter covering the controllability addresses the control loop together with the basic equations of ship motion. stability and associated linear equations, stability and control, turning ability, controls-fixed stability and coursekeeping, hydraulic models, free-running tests, non-linear motion equations, acceleration/stopping/backing, hydrodynamic coefficients, auto-control systems, waterway interactions, performance requirements, design applications, special symbols, control devices and many other critically important topics.
