摘要：海洋平台是一种由各种设备和材料组成的庞大的开采工具，由于它的庞大和复杂性，在海洋平台设计阶段计算所得的重量和重心位置，与海洋平台建成后的实际重量和重心位置往往有一定差异，这些误差是不可避免的。由于海洋平台的重量和重心与该平台的稳性有着极其重要的联系，上述两者相加，所以在海洋平台建成以后都要进行倾斜试验，以便准确地求得重量和重心的位置。不仅可以用来计算该平台的稳性，而且为以后设计同类海洋平台提供了可靠的参考资料。因此倾斜试验的目的是确定海洋平台的重量和重心位置，试验的结果要求精确可靠。以此来确定该海洋平台在海中的稳性合格与否。本论文主要展开以下工作：
1、搜集资料，了解课题内容，确定技术方案；
2、计算空船重量和其组成；
3、熟悉悬臂梁滑移法；
4、运用摆锤法和U型管读数计算横倾角；
5、计算初稳性和重心位置；
6、自由液面修正；
7、完成数值计算与记录并撰写论文。

Abstract：Offshore platform is a huge mining tool consists of all kinds of equipment and materials, because of its large and complex, calculated the weight and center of gravity in the design stage of offshore platform, and platform after the completion of the actual weight and center of gravity tend to have certain differences, these errors are inevitable. The stability of offshore platform and the platform weight and has an extremely important link, the two together, so the tilt test in offshore platform built after all, in order to accurately determine the weight and center of gravity position. Not only can be used to calculate the stability of the platform, but also provide a reliable reference for the design of the same kind of offshore platform. Therefore, the purpose of the tilt test is to determine the weight and center of gravity of the offshore platform. In order to determine whether or not the stability of the offshore platform in the sea. The main work of this paper is as follows:
1, To collect information, understand the content of the project, determine the technical program and complete the report
2, Calculate the weight of empty ships and their composition；
3, Familiar with cantilever slip method；
4, The use of pendulum method and U-tube readings to calculate the heel angle； 5, Calculate the initial stability and center of gravity position；
6, Free liquid surface correction；
7, Complete the numerical calculation and record and write papers。
Keywords: ship, jack-up platform, tilt test, weight, center of gravity
