Time Domain Simulation of Jack-Up Platform in Second-Order Irregular Seas

This paper reviews the significance of applying second-order irregular waves for assessing hydrodynamic loads on a jack-up platform. The study is based on a realistic jack-up model. The wave load is determined utilizing Morison equation. The study focuses on extreme wave elevations when the drag load component dominates and the magnitude of wave particle horizontal velocity is crucial. Both extreme surface elevation and wave particle kinematics are observed. For wave particle kinematic, two different stretching methods are compared. The static response of a pile structure using the second-order model and the 5th Stokes wave are compared. In the end, a dynamic analysis of the jack-up utilizing a second-order irregular wave model is performed.
