| Abstract: | The finite element model of the truss jack-up platform is introduced,especially for some key positions such as hull,the connection of leg and hull,the interaction between spud can and soil is detailed clarified.The method of hydrodynamic coefficient of the truss leg platform,inertia force and P-Delta effect are given out.Site specific analysis of the leg of some truss self-elevating jack-up platform is carried out by SACS software,at the same time the environmental loads,inertial loads,reaction of spud-can ... |
