摘要
Abstract
In view of the problem of disposal after decommissioning of offshore oil platforms,the reuse of abandoned jacket into artificial reef has become one of the most feasible solutions.To prevent structural damage during the settlement of the cut-off jacket structures,a hydrodynamic model is deduced based on the Morrison equation.Contact and collision models between the jacket structure and the seabed plane are established,and a dynamic study on the settlement process of the cut-off jacket structures is conducted.Meanwhile,the settlement process of the jacket structure under three different initial inclination angles is simulated using the dynamic software ADAMS,and strength analysis of the landed jacket structure is performed using the finite element analysis system ANSYS Workbench.The results indicate that as the inclination angle of the jacket structure during deployment increases,the stable settlement speed decreases.The impact force at the bottom edge during touchdown is relatively small but the stress is larger,approximately 15 MPa,particularly more obvious in the middle area.This research can offer references for the rational planning and design of jacket structure placement and provide theoretical support for optimizing the placement process of jacket structures.关键词
