A semi-submersible vessel’s motion model was constructed in order to find out the key factors to induce the parameter rolling for semi-submersible vessels carrying heavy cargo in the long waves. Then, the variable parameter analysis method was used to quantitatively calculate and analyze the influence degree and rule of the key factors including the wave length, wave height, metacentric height and speed variation on the navigation safety of the semi-submersible vessels. Finally, based on the case analysis, the critical interval values of semi-submersible vessels without parametric roll are obtained. The study of this problem will help improve and standardize the stability criterion of semi-submersible vessels.
