Numerical Analysis of the Dynamic Response of an Offshore Platform with a Pile-Soil Foundation System Subjected to Random Waves and Currents

Abstract

In this study, a three-dimensional numerical model was developed based on a modal analysis and substructure method. The devised model was employed for an evaluation of the dynamic response of a bottom-mounted platform with a pile-soil foundation system that was subjected to random waves and currents.
