4、ean energy engineering to open sea, the coupling prediction of ocean platformmotion response is becoming one of the hotspots. In this paper, a floating ocean platform is taken as the study object, and themotion response of the floating platform and the mo
5、oring system in wave is calculated and analyzed by full coupling method.Based on the indirect time domain method, this paper establishes and solves the time domain motion equation of the floatingplatform, and computes the time domain motion equation numer
6、ically. The motion equations of the mooring system are es-tablished and solved based on the theory of catenary equations and the three-dimensional mass method in full vector form.Finally, the full coupling calculation method of the platform and mooring sy
7、stem is proposed, the force and displacement ofthe mooring and floating platforms are taken as the input and output of two motion equations in each calculation step. A sim-plified floating platform is calculated and the motion response of the platform and
8、 the force of the cable are analyzed. Thispaper can be a reference for solving related engineering problems.Keywords: floating platform;mooring system;motion response;coupling prediction0 引 言状态时的系泊缆索张力。单鹏昊[5]应用有
