Volume 1 Regulation and Operation: Part 1:Development of Stability Standards; Historical development and basic stability concepts, Development and present status of stability standards, Standards based on the consideration of heeling moments, Statistical methods of developing stability standards, Probabilistic approach to the development of stability standards, Model tests of capsizing, Stability regulations - future outlook. Part 2: Operational Aspects of Stability and Safety; Operational stability - hydrostatics and hydrodynamics, Sea environment, Roll excitation and influence of speed and heading, Resonance and large roll motion, Forces due to roll motion, Measurement and accuracy of stability status, Safety management and operational requirements.  Volume 2 Risk of Capsizing: This book deals with the many modern approaches that have been developed for analyzing ship dynamic stability and capsizing. The emphasis of the book is on the probabilistic assessment stability. However, in order to evaluate ship dynamic stability and capsizing the reader must first formulate the nonlinear ship dynamic problem. The book raises the level of understanding of ship dynamic stability research to that of hydrodynamics and structures, and it paves the way to consideration of ship stability safety as one aspect of the up-and-coming discipline of nonlinear dynamics of ships.
