【摘要】：针对胜利902铺管船进行海底管线铺设过程,研究了铺管船铺管作业方式,分析了胜利902铺管船耐波性和锚泊定位系统、进行了海底管线基本参数的设计和托管架系统的强度校核,研究结果对胜利902铺管船进行海底管线铺设具有重要的指导意义。论文详述了铺管船法中卷筒铺设、J型铺设、S型铺设等三种铺管法,比较各自的优缺点及其适用范围,并简要介绍S型铺管法的发展历程和目前国内外发展现状;针对胜利902铺管船,使用三维势流挠射/辐射的源汇分布法进行耐波性运动响应分析和锚泊分析的水动力计算,其中耐波性运动响应分析得到的船舶运动相应系数(RAOS)用于铺管船铺管作业过程的动态计算;锚泊分析得到进行铺管作业的极限水文环境参数,是判断铺管船能否在某种海域进行铺管作业的首要条件。以某油区天然气外输项目为依托,参照DNV-OS-F101规范的相关内容,对海底管道进行在位强度校核,概括海底管道管径设计和壁厚计算的参数选择计算过程。利用工程实例,详细计算铺管船进行S型铺设作业全过程的管线所受应力情况,并提供起始铺设过程、正常铺设过程、弃管收管过程等的计算模型,对铺管船的铺管作业能力进行评估。利用ANSYS软件,结合OFFPIPE软件计算结果,对托管架系统进行整体强度和局部强度计算校核,以确保托管架系统的安全性。
[Abstract]:The victory in the 902 pipe laying vessel laying process of submarine pipeline, paving pipe laying operation mode of the boat, winning 902 pipe laying ship seakeeping and mooring system, check the strength of the basic parameters of the pipeline design and hosting frame system, the results of the 902 victory of subsea pipeline with pipe laying vessel an important guiding significance. The paper introduces the laying of pipe laying method in ship roll laying, laying type J, S type three laying pipe laying method, compare their advantages and disadvantages and the applicable scope, and briefly introduces the development process of S pipe laying method and the present development situation at home and abroad; for winning 902 laybarge the use of three-dimensional potential flow, diffraction / radiation source distribution method to calculate the hydrodynamic analysis and mooring response of seakeeping motions, the seakeeping motion response analysis of ship motion corresponding coefficients (RAOS) for laying pipe laying barge for Dynamic computing process; analysis of mooring pipe laying operations limit hydrological and environmental parameters, the judgment whether the primary condition for pipe laying ship pipe laying operations in a sea area. In a certain oil field natural gas transportation project, according to the relevant contents of the DNV-OS-F101 specification, the submarine pipeline in the strength check, general parameters the diameter and wall thickness of pipeline design calculation selection and calculation process. Based on the engineering examples, detailed calculation of pipe laying ship type S laying the whole process of pipeline stress, and start laying process, normal laying process, calculation model of abandoned pipe closed tube process, the pipe laying ship shop operation capacity evaluation. Using ANSYS software, the calculation results with OFFPIPE software, the overall strength and local strength of the stinger system calculation, to ensure the safety of the stinger system.
