Calculation and analysis of the wave load of jack-up offshore wind turbine installation vessel during dynamic positioning

Abstract

The jacking-up offshore wind turbine installation vessel will under complex ocean condition during its sailing, positioning and working, and the wave loads are needed to be calculated and analyzed as the most complex loads. This paper adopts Near Field Integral Theory which based on integral surface, using ANSYS software to establish the precise geometric model, and then calculate wave loads and motion response transfer function through the AQWA modules for wind power installation vessel in three degrees of freedom and different angles to the flow direction. Meanwhile, the calculation shows that wave direction has a greater impact on the motion response of jacking-up offshore wind turbine installation vessel.
