【摘要】：随着世界经济增长和科技领域发展,人类社会对环境资源越来越依赖,而陆地油气等不可再生资源,经过长时期大规模持续开采,已逐渐贫乏。最近几年,海洋石油开采逐步升温,自升式平台在海洋石油的探索勘测、开采中起到重要作用。这种大背景下,自升式平台的需求逐年增多。升降系统是自升式平台非常重要组成部分,客户对升降系统的制造质量和功能调试提出了越来越高的要求;研究和完善升降系统建造和调试工艺是船厂目前亟待解决的问题。本文以2014年中集来福士交付的自升式平台HYSY932为研究对象,分析了升降系统的传统建造和调试中经常出现的各种重要难题,详细介绍桩腿建造,固桩架建造,升降装置安装和系统调试等工艺中出现的问题和困难点,通过比较其他船厂的建造流程,研究了适合船厂的升降系统建造工艺,文中并体现了关键环节的注意事项,解决了工艺执行过程中发现的难题。桩腿结构和固桩架单元是升降系统的重要结构单元,其建造难点在于焊接温度、尺寸精度和焊接质量控制上;为了提高精度采用双面同时对称焊接、特殊胎架辅助、临时马板固定、画线洋冲标记、经纬仪实时测量等方法。焊接质量的控制更加重要,其中热处理、焊接材料和焊接方法、焊工的技能、预热和保温等都是直接影响焊接质量的重要因素。在建造过程中,如何克服产生的应力和变形,如何修正自身建造精度和公差偏大问题,在本文都有明确说明。升降装置的安装和系统调试流程以及注意事项在本文中也重点阐述,总结了升降系统安装和调试中遇到的疑点、难点,并研究出了具体的解决方案,最终完善了工艺的理论基础,重点挑明了注意事项,为在建项目建造提供了理论参考,使现场建造指导工艺更浅显易懂。
[Abstract]:With the growth of world economy and the development of science and technology, human society is more and more dependent on environmental resources, while non-renewable resources such as land oil and gas have become poor after a long period of large-scale continuous exploitation. In recent years, offshore oil exploitation has gradually heated up, and the self-elevating platform plays an important role in the exploration, survey and exploitation of offshore oil. In this context, the demand for self-elevating platform is increasing year by year. Lifting system is a very important part of self-lifting platform, customers put forward higher and higher requirements for the manufacturing quality and function debugging of lifting system, and studying and perfecting the construction and debugging technology of lifting system is an urgent problem to be solved in shipyard at present. In this paper, HYSY932, a self-lifting platform delivered by Laifus in 2014, is taken as the research object, and various important problems often occur in the traditional construction and debugging of the lifting system are analyzed, and the pile leg construction and pile fixing frame construction are introduced in detail. By comparing the construction flow of other shipyards, the construction technology of lifting system suitable for shipyards is studied, and the matters needing attention in the key links are also reflected in this paper. The difficult problems found in the process of process execution are solved. Pile leg structure and fixed pile frame element are important structural units of lifting system, and their construction difficulties lie in welding temperature, dimensional accuracy and welding quality control. In order to improve the accuracy, double-sided simultaneous symmetrical welding, special tire frame assistance, temporary horse plate fixation, drawing line impact marking, theodolite real-time measurement and so on. Welding quality control is more important, among which heat treatment, welding materials and welding methods, welder skills, preheating and heat preservation are all important factors that directly affect welding quality. In the process of construction, how to overcome the stress and deformation and how to correct the problem of large construction accuracy and tolerance are clearly explained in this paper. The installation, system debugging flow and matters needing attention of the lifting device are also described in this paper, the doubts and difficulties encountered in the installation and debugging of the lifting system are summarized, and the concrete solutions are worked out. Finally, the theoretical basis of the process is improved, and the matters needing attention are singled out, which provides a theoretical reference for the construction of the project under construction, and makes the field construction guidance process more simple and easy to understand.
