The dynamic responses of jack-up platform, in floating state, are calculated numerically. The finite element models of a jack-up are made. And the dynamic responses of the jack-up are simulated when the spud-can is driving downwards at different depths while the jack-up platform is floating on the sea(1). The responses sensitivity of different waves are also analyzed. The results show that the responses, especially the heave, surge and sway are much larger than other degrees of freedom, during the floating state. The roll and pitch become smaller, when the depth of the spud-can increases. While the heave of the platform becomes larger when the depth of the spud-can increases in the pile driving process. Different degree of freedoms are sensitive differently to different wave directions.
