Extreme response of a flexible riser system using a complete nonlinear long-term approach

A procedure for a complete long-term analysis is outlined. Special considerations that should be taken for flexible riser systems, selection of probability models for the short-term distribution and fitting procedures are discussed. The suggested probability models and fitting procedures are evaluated for responses in a riser with a steep wave configuration. The selected probability models and fitting procedures are used in a long-term analysis for the riser system.
