总体介绍了课题研究背景和研究思路,围绕2013年工作任务,总结了取得的技术进步,包括平台的概念设计、整体运动分析、立管设计等新型的干树半潜浮式生产平台其创新点是把平台的立柱和甲板分开,从而使平台的主要尺度能够根据稳性和运动的优化要求进行独立选型。针对干树生产平台的技术要求,围绕稳性、控制垂荡运动及横、纵摇运动特性,对平台主尺度进行了优选,使其具有良好的稳性,同时又保证其垂向运动的固有频率高于波浪能量频率,并且使波浪力在波浪能量周期内有相对的抵消。
The research background and research ideas of the project are generally introduced. Based on the tasks in 2013, the technological progress achieved is summarized, including innovative concepts such as the conceptual design of the platform, overall sports analysis and riser design, etc. The platform is separated from the column and the deck, so that the main dimensions of the platform can be based on the stability and movement of the optimization requirements for independent selection. According to the technical requirements of the dry tree production platform, the main dimension of the platform was optimized around the stability, the control of the heaving motion and the characteristics of the horizontal and the vertical movements so that it has a good stability and at the same time ensures the inherent vertical movement The frequency is higher than the frequency of the wave energy and gives a relative cancellation of the wave force over the wave energy period.
