Nonlinear analysis of slow drift extreme responses of a compliant offshore structure. (English) Zbl 1269.74068

Summary: This paper first demonstrates that the accuracy and efficiency of the method of numerical simulation often used is not very high in predicting the slow drift surge extreme responses of a compliant offshore structure. Next, the slow drift surge extreme responses of the structure are analyzed via the path integral solution (PIS) method, and the accuracy and efficiency of the PIS method is found to be higher than those of the numerical simulation method. A compound PIS (CPIS) method is first proposed in this article to further improve the efficiency of the path integral solution method, and the accuracy and efficiency of the CPIS method is validated.
