Abstract

In order to research the performance of the newly developed offshore jack-up platform with separate foundation, the overall performance of top and lower units, such as afloat stability, stability against overturning, and stability against sliding were analysed. At the same time, FEM models of the newly developed platform were built for the analysis of structure strength under different working conditions. Simulations of crash and vibration between the upper and lower parts when connecting and separating were also performed. Furthermore, laboratory tests of the experimental model were done. By contrasting, the analysis of the mathematical model was verified. Results in this paper showed that the newly developed platform was feasible for practical use; it could not only increase the working water depth but also reduce the cost of construction.
