Abstract
Understanding the environmental load effects such as wind,wave and current is crucial for the design and optimization of floating foundations and mooring system.This paper takes a 15 MW floating foundation as the research object,the influence of environmental loads,such as wind,wave and current,on the motion of floating foundation and the force of mooring system is systematically and quantitatively analyzed.Firstly,a new 15 MW floating foundation is designed based on the INOWINDMOOR 12 MW and TaiDa 15 MW floating foundations,a hydrodynamic analysis model is established in ANSYS/AQWA,and the wind load of wind turbine and the flow load of ocean current are added through the wind and flow coefficients.Secondly,the analyses are conducted on the characteristics of floating foundations and mooring forces under the actions of independent and coupled environmental loads of wind,wave and current.The results show that the motion of floating foundation and the forces of mooring system are mainly affected by wind and current forces,and the wave will intensify the reciprocating of floating foundation motion and mooring force,and increase the amplitude of motion and mooring force;the current load has a significant impact on the movement of floating foundations and forces of mooring system,especially when it coupled with wind and wave,so in actual engineering design,current load should be given special attention.关键词
