摘要我国南海是世界公认的各种矿产能源的富藏海域，近年来，国家对于南海的保卫和开发力度逐年加大，虽然该海域仍然存在地区性不稳定因素，但我们对于海洋资源开发运输的研究工作却不能因噎废食。在国内，由哈工程，上海交大，江科大等船舶一流院校展开的相关类型研究正在有条不紊的进行着。在此，本文使用法国船级社所开发的HydroSTAR软件对并靠液化天然气船在不同水深条件下的波浪中的运动分析，得出相关数据。86042

  本文第一章绪论部分将为大家介绍所选课题的内容及意义，并且详细介绍HydroSTAR软件的使用说明，参数设置以及将会遇到的相关问题，还有所需要的输入的网格文件的采集，设置以及修改的相关要求。第二章将介绍进行相关试验所需要用到的各类波浪势流理论 ，第二章第一节主要描述海洋中的波浪运动情况以及基本参数和波浪理论，为论文实验提供理论依据；第二节则通过对势流理论的介绍学习加深实验的可行性效果以及科学严谨性，将波浪和势流理论分开介绍正是为了读者更好的了解波浪的运动情况以及对船体造成的影响；第三节通过对船体内部自身状况的分析，着重介绍液舱晃荡效应对船舶运动造成的影响。第三章将通过数据的输入计算得出各项结果并做出科学分析。通过对比已知数据得出最终的结论。结论部分我们将对全文做概括性总结并对为本文提供过帮助的各位专家学者表示真挚的感谢。

Abstract  The South China Sea is recognized as a place with variety of mineral energy 。 In recent years, government has take a lot of ways to defend and development soutn china sea, Although the area still exist regional instability,we cannot be afraid of this condition because of the reason 。In China, some famous universities such as Harbin Engineering University, SJTU and JUST have started to carry out some relevant research。 In this paper, we use HydroSTAR developed by Bureau Veritas software on and by liquefied natural gas ship in various conditions of wave to motion analysis, related data is obtained。 In the first chapter, I will be for all the selected content and significance of the subject, and introduced in detail HydroSTAR software using that input parameter settings, and that will be met, and the need of the grid file collection, set and modify the relevant requirements in detail。 The second chapter will introduce the related to test the need to use all kinds of wave potential flow theory, the first section of the second chapter describes the main hull external factors。 The second section introduce related effects of inside the hull of ship motion。 The third chapter will go through the input data calculation concluded, and based on the requirement of related theory, the analysis of the data, the comparison of the known data draw the final conclusion, and leak fill a vacancy。 It is pointed out that other deficiencies existed in this paper。 The fourth chapter will make a brief summary of the full text of the analysis and attach the final results。 Calculate the various parameters of the ship in the wave needs, to provide a reference for the actual operation of the scientific data。 At this stage, we need to rely on the operation of the LNG ship in the wave motion analysis by means of a detailed description of the technical means to solve the actual problem。 The train of thought of this paper first make the grid data of hull, on the basis of the original ship by a variety of ways shrink or enlarge, and keep the waterplane area basically fixed in the original position and input data generated various hydrostatic stress wave data, drawing table, ideas, to complete。
