导管架平台上部组块结构优化研究

目前东海已建在产的生产平台全部为导管架平台，部分导管架平台的上部组块存在结构偏复杂、杆件受力不均衡、甲板设备布局不合理等问题，不仅加大了平台建造难度和工作量，而且增加了项目工程投资。因此，有必要对东海已建导管架平台进行结构评价和优化设计。在此基础上选取东海具有代表性的导管架平台为研究对象，对其上部组块进行优化设计，并运用SACS软件对上部组块进行在位静力分析和吊装分析，最终形成了导管架平台上部组块优化技术方案，实现了上部组块结构减重，从而节省制造费用，降低成本。该文旨在为今后类似导管架平台设计提供新的思路和借鉴。

At present, in East China Sea a number of production platforms have been built, all of which are jacket platforms, and the topsides on some jacket platforms have problems such as complex structure, uneven force on members, and unreasonable layout of deck equipment, which not only increase the difficulty and workload of platform construction, but also increase the investment in project engineering. Therefore, it is necessary to evaluate the structure and optimize the design of the established jacket platform in East China Sea. On this basis, the representative jacket platform of East China Sea was selected as the research object, the optimization research and design of the topsides were carried out, and the SACS software was used to analyze the in-place static analysis and lifting analysis of the topsides, and finally formed the technical scheme of the topsides optimization of the jacket platform, which realized the weight reduction of the topsides structure, thereby saving manufacturing costs and reducing costs. This paper aims to provide new ideas and reference for the design of similar jacket platforms in the future.
