This volume provides a theoretical and practical introduction on the prediction of waves, wave forces and the reliability of marine structures. Chapter 1 contains a description of contents and methods, together with 24 case studies presented as problems with solutions. The solutions are given as brief reports with reference to the theories and equations applied. The three remaining chapters contain 24 theoretical articles. The volume offers an indispensable reference source for all those interested in the practical and theoretical aspects of topics relevant to the marine industry. The practical part provides the background needed for consultant services, while the theoretical part gives the combination of hydrodynamics and statistics required in structural reliability methods.
