摘要
为替代全水深系统进行混合模型试验,设计了等效水深截断系统。同时考虑总系泊系统以及具有代表性的单根系泊缆静恢复力特性相似,采用改进的变尺度混沌算法对等效水深截断系泊系统进行优化计算。选取了一工作水深为1500m的新型单柱式(Spar)平台,对其截断水深为700m的等效截断系泊系统进行优化设计,数值试验结果表明,截断系统的设计是合理的、可靠的。
In order to replace full-depth system to perform the hybrid model testing,the equivalent water depth truncated system is designed.Considering the similarity of static characteristics of total mooring system and the representative of the single root mooring ropes between the truncated mooring system and full-depth mooring system,the improved mutative Scalechaos algorithm is employed to the optimization of the equivalent water depth truncated mooring system.Based on a spar platform operated in 1,500m water depth,optimal design is exercised for its truncated mooring system in 700m water depth.The numerical experimentation result indicated that the design of the truncated mooring system is reasonable and reliable.
