This paper mainly studies the numerical analysis of the Pendulous Installation Method of a pump module in 1,500 meter water. A nonlinear time-domain coupled vessel and the pump installation system is established using ORCAFLEX riser program to simulate the pendulous free-fall motion of the pump module. The analysis studies the effect of environmental loads and vessel’s dynamic response on the entire installation system. Different directions of environmental loads and a series of sea-states defined using significant wave heights are taken into consideration. The results show that the optimum direction of the environmental loads is taken as 180 degrees (aganist vessel length), and the dynamic response of the vessel has a great impact on the entire system and should not be neglected.
