摘要
铺管船在海上敷设海底管道是动态的并且非常复杂的过程,为了合理分析铺管船锚泊方案,基于Ansys-AQWA软件,考虑风载荷、流载荷、波浪载荷等因素,对铺管船与锚泊系统进行耦合时域分析,给出了针对多点定位系泊系统海洋工程船的分析流程,而且从铺管船锚泊移位系统的强度校核结果、各项运动最大位移、操作简便性等方面评析铺管船作业锚泊方案,得出较优方案指导实际工程。结果表明,本文采取的方法具有工程应用性,评析结果可以作为实际工程的参考。
The operation of pipe-laying vessel in subsea pipeline offshore installation is dynamic and complex process, in order to give the reasonable analysis of pipe laying vessel mooring scheme, based on the ANSYS-AQWA software, considering wind load, current load and wave load, the coupled analysis between pipe-laying vessel and mooring system is brought out in the time domain. According to the analysis process of multi-point positioning mooring system of marine engineering vessel is given, and take the strength assessment of mooring system, the maximum displacement of the movement on each direction, the simple operation into consideration to analysis the operating mooring scheme of pipe-laying vessel. According to the analysis results from this paper, the optimum scheme is obtained to guide the actual project. The results show that, the methods from this article has engineering application and analysis results can be used as a practical reference.
