Abstract

Jack-Up Ships are specialized vessels in the field of marine engineering, capable of meeting various needs such as offshore oil and gas exploration and extraction, as well as transportation and installation of offshore wind turbine units. With broad prospects for application, they hold significant research value and strategic importance. Based on the finite element analysis method for forced vibration response analysis of jack-up ship, a finite element models of jack-up ship is established to analyse the whole ship modes and the natural and excitation frequencies, and the whole ship vibration response is solved by the finite element method with modal superposition after loading the excitation loads. The reason why the response peak is not near the excitation frequency is analyzed, providing a reference for vibration prediction and control.
