| 将truss spar平台主体和系泊系统看作耦合系统,采用ANSYS/AQWA在时域对truss spar及其系泊系统进行耦合动力响应分析,在8点和12点系泊情况下获得4种不同工况下平台主体的垂荡和纵荡响应和系泊缆的张力响应。结果表明:当系泊系统处于破损状态时,平台的纵荡要远大于系泊系统处于完整状态时的水平位移;极限工况下,平台的运动和张力响应要比作业工况下的响应更大; 相对于8点系泊系统,12点系泊系统的运动和张力响应更小。 |

| Abstract: |
| The main body of truss spar platform and mooring system were considered as an integrated coupled system, through which the coupled dynamic analysis were conducted using ANSYS/AQWA, and the motion response and tension response of truss spar platform at four different working conditions were obtained. It is found that the mooring line failure would increase the surge response and tension response drastically. The extreme environmental loads would increase the response of truss spar. Besides, comparing the results of truss spar with 8-point mooring system and 12-point mooring system, 12-point mooring system would decrease the response of truss spar. |
