Nonlinear Methods in Offshore EngineeringThe design of an offshore structure is based on the extreme responses experienced by the components of the structure under the influence of the environment faced by the structure in its lifetime. This volume gives a comprehensive review on the currently available and emerging techniques for the determination of extreme responses in a nonlinear marine structure and system. The volume is divided into two parts: The first part presents the nonlinear characteristics of wave-induced forces and corresponding structural responses, and the second examines the extreme value analysis of nonlinear systems relevant to offshore and marine structure design. The generic procedures for the nonlinear analysis of marine structures are reviewed, and the methods in which they may be applied to the probability analysis of extreme events is discussed. Different types of nonlinear behaviour applicable to the various classes of offshore structures are included, as well as a review of the various generic procedures for nonlinear analysis with emphasis on the time domain solution. The fundamental principles of Gaussian and non-Gaussian random processes are addressed in detail. |
