1、第2卷第6期海洋工程装备与技术V01.2,No.60超深水半潜式钻井平台设计技术创新与应用谢彬,李阳,张威,谢文会,王俊荣(中海油研究总院,北京100028)摘要中国南海环境条件恶劣,夏季强台风频发,冬季突发性风暴不断,内波时隐时现,对深远海作业的半潜式钻井平台的安全性、总体性能、作业效率等方面均提出了非常高的要求,南海超深水半潜式钻井平台的设计面临多项世界级的技术挑战。结合南海超深水半潜式钻井平台的研发过程,重点叙述在南海内波流载荷、甲板可变载荷、慢漂运动预测、简化疲劳分析等方面取得的创新性成果,并对南海超深水半潜式钻井平台的总体方案加以介绍。通过多项重大技术创新攻关,最终
2、研发出世界首次针对南海特殊环境条件、具有自主知识产权的超深水半潜式钻井平台新船型。平台作业水深3000m、钻井深度10000m、可变载荷9000t,稳性和结构强度满足南海200年一遇环境条件要求。与世界先进的同类平台相比,其运动性能和作业性能优良,平均钻井作业时效较国际同类平台提高lO%,综合技术指标世界领先。关键词超深水半潜式钻井平台;内波流;慢漂;简化疲劳;总体方案中图分类号U674.38+1文献标志码A文章编号:2095—7297(2015)06—0353—08InnovationandApplicationonDesignTechnologyofUltra.Deepw
