Numerical analysis of pontoon-chain system based on nonlinear FEM

LI Ya;CHENG Ze-kun;CCCC Third Harbor Consultants Co.,Ltd.;  
The nonlinear Finite Element Method( FEM), which is convenient for engineering applications to the pontoon-chain system, is introduced to simulate the large deformation and contact behavior with mud plane for mooring chains. According to the calculation flow given,quasi-static analysis can be carried out to get the displacement and tensile force of pontoon-chain system under external load with water level variation. A practical case,a floating yard of the MSA somewhere, is analyzed to validate the applicability and practical value of the method presented.
