Analysis on Dynamic Response of Platform-Riser-Wellhead Coupling System
The platform-riser-underwater wellhead coupling system is the core equipment of offshore drilling and production operations,which together constitute the working space of underwater production operations and provide a channel for mud return.Its dynamic response is of great significance to the safety and normal operation of offshore platforms.In this regard,the finite element software is used to simulate and analyze the coupling system,and the influence of different platform motion amplitudes on the dynamic response of the coupling system is explored.The results show that the response of the coupling system is nonlinear,and the dynamic response of the coupling system increases with the increase of the top offset of the platform.
