Abstract
Ocean platforms are widely used to extract submarine oil. For a long time, they are subjected to a variety of environment loads, such as those from winds, waves, currents. In this study, the torsion problems of a spar platform with cracks under wind load were investigated. The main body of spar was assumed to be a homogeneous material cylinder, then the torsion fracture problem of the cylinder was considered. The problem was reduced to solve the boundary integral equations on crack and boundary, torsion problem of the spar platform main body with a straight crack under various wind loads was calculated by used the boundary element method. The obtained results showed that with the increase of wind scale, the allowed maximum crack size in the main body of spar platform was decreased gradually, cracks had some effect on the safety of the spar’s main body in marine engineering. Especially in severe ocean environments, the risks of fracture failure of main body with cracks should not be overlooked, and should be considered during the process of marine structure construction and usage.
