Research on Different coupling methods in Jack-up Simulation

摘要

Jack-up platform occupies an important position in marine oil exploitation due to its advantages. A finite element model of a Jack-up was constructed and analyzed. And Different coupling methods were used to simulate the links between the boat hull and legs. The two kinds of coupling methods are the coupling DOFs/Mstr method and the Rigid Region coupling method. And the calculation results showed that the Rigid Region coupling method was better than the coupling DOFs/Mstr method. The Rigid Region coupling method was recommended in the actual engineering.
