摘　　要：BINGO-90 0 0型平台是目前世界上最先进的第五代半潜式钻井平台 ,能在深海 (工作水深 3 0 0 0 m) ,恶劣气候海况 (零下 2 0℃、风速 41 m/s、浪高 3 2 m)下开采石油。以 BINGO-90 0 0型平台为例 ,介绍了平台结构和压载状态实时监测系统设计的关键技术问题 ,以及基于疲劳寿命分析的结构设计思想。展开了该平台波浪载荷的分析计算 ,在此基础上对主体结构进行了三维有限元强度分析。对平台特殊结构如 K型管节点及支撑结构和立柱结构进行了强度分析和疲劳寿命分析。还研究了平台吃水数据采集、压载状态监测等技术。通过以上关键技术的研究 ,平台结构设计更趋安全可靠合理 ,既具有必需的强度储备 。BINGO 9000 is the fifth generation advanced semi submersible rig. It is capable of operating and exploiting oil in deep sea (operating depth 3000m), and under severe sea condition (-20℃, wind velocity 41m/s, wave height 32m). Therefore the structure design and the ballast condition monitoring system must be reliable, reasonable and safe. This article presents a structural design concept based on fatigue life analysis for the ocean rigs with this technical feature. The load analysis and calculation for the rig under the wave action are carried out. Based on this, three dimensional finite element strength analysis is conducted. A special strength analysis and fatigue life analysis are made for rig′s special structures such as K node of pipe braced structure and column structures, etc. The development of the ballast condition monitoring system is presented.
