摘要
以某新型深水桁架式Spar平台为研究对象,应用设计波法,对Spar干式拖航运输过程中Spar平台和拖船的整体结构强度,进行计算和分析。依据三维绕射理论计算波浪诱导载荷与运动,采用谱分析法确定设计波参数。在建立了桁架Spar平台与运输船的总体结构模型后,对结构模型施加设计波浪载荷,通过有限元计算分析,获得了总体结构的应力计算结果和应力分布趋势,分析结果可为桁架Spar平台的干式拖航安全评估提供依据。
The scope of the work is focused on global transportation vessel, using design wave method under strength analysis of the deepwater truss spar and global loads during the spar dry towing transportation. Wave induced loads and vessel motion are calculated by means of three-dimensional diffraction method. The parameters of design wave are obtained by spectrum analysis method. After global structural model was built, wave load was applied to the global structural model. The stress and its distribution trend were obtained by using finite element analysis. Calculating result provided basis for evaluation of structure strength.
