Abstract

With the development of marine resources, a dual-platform joint operation has been paid more attention. In this paper, the mooring layout space and relative motion limitation of the dual-platform berthing operation were fully considered. A new hybrid mooring system with “X + buoy” combination was designed based on the characteristics of catenary and tension mooring. The hydrodynamic characteristics of the new mooring system were analyzed by combining numerical simulation with model experiment. Under the regular and freak waves with different wave heights and periods, the time-domain full-coupling analysis method was used to study the hydrodynamic characteristics of the mooring system. It can be found that the arrangement of dual-platform under 0 ◦ wave direction is optimal, and the “X + buoy” combined mooring system designed in this paper has a good follow-up between the two platforms under different regular and freak waves. The relative motion response between the two platforms can be effectively controlled, and finally the positioning of the dual-platform joint operation is realized. Research results of this paper provide a theoretical basis and technical support for the hydrodynamic performance analysis and safety assessment of deep-sea offshore platforms in China.
