摘要
为分析海洋工程结构物在波浪中的运动响应,以用于铺设海底管道的铺管船和托管架为研究对象,阐述大尺度结构物(铺管船)与小尺度结构物(托管架、管道)分别适用的计算理论,采用AQWA软件对铺管船-托管架在不同浪向下的动力特性进行分析。通过频域水动力分析比较铺管船和托管架在规则波与不规则波下的6个自由度的运动,得到铺管船和托管架的运动响应幅值算子(response amplitude operator,RAO),通过时域分析计算铺管船和托管架在实际海况下的波浪载荷时程,为托管架强度分析奠定基础。
To analyze the motion response of offshore engineering structures in waves,the pipe laying vessel and stinger used for laying submarine pipelines are selected as the study objects,the applicable computation theory of large-scale structure(pipe laying vessel)and small-scale structure(stinger and pipeline)is expounded,AQWA software is used to analyze the dynamic characteristics of the pipe laying vessel-stinger under different waves.The six direction motions of the pipeline laying vessel and stingers under regular and irregular waves are compared using frequency domain hydrodynamic analysis,and the response amplitude operator(RAO)for the motion response of the pipe laying vessel and stingers is get.The wave load time history of the pipe laying vessel and stingers under actual sea conditions is computed using time domain analysis,which lays the foundation for the strength analysis of the stinger.
