| Abstract: | Mathematical model of the deep-water jack-up offshore platforms was estab- lished based on the finite element method. Based on linearized Morison equation and random wave theory, random wave load was calculated using spectrum analysis method. A typical deep water jack-up platform was taken as the prototype, it＇s finite element model was estab- lished by ANSYS finite element software. Furthermore, Modal Analysis and Dynamic Re- sponse Analysis of the platform structure were made, and the frequency and dynamic charac- teristics of the platform were analysed. |
