FPSO/FSO: State of the art

Floating productions systems have been utilized in remote offshore areas without a pipeline infrastructure for many years. However, they have become even more important with the push by the offshore industry into ever deeper waters. Floating production, storage, and offloading/floating storage and offloading (FPSO/FSO) systems have now become one of most commercially viable concepts for remote or deep-water oilfield developments. In this article, the advantages of FPSO systems are explained, and their present status of maturity and utilization around the world is reviewed. Recent trends in mooring systems, hull construction, safety, and operational issues are summarized from a technical viewpoint. Finally, the technical challenges and future prospects of two significant growth areas, i.e., gas-field development and deep-water development, are discussed.

胜利埕岛油田海上作业平台插桩分析中的几点误区思考

文章通过阐述多个具体的插桩分析失误案例,结合行业规范及土力学原理,对胜利埕岛油田海上作业平台插桩分析中的几种常见误区进行思考总结,分析了常见误区的类型、产生原因及不利影响,并提出了应对措施,以纠正一些认识上的错误,提高插桩计算分析的准确度。分析认为,因对地层分类不清、岩土性质把握不准、特殊地层认识欠缺、地层均匀性划分不精确、结构与土的互动响应考虑不充分等,而造成插桩分析失误的情况比比皆是,给油田的生产带来了很多不必要的损失。提高勘察质量、采用多种手段勘察、重视地层的均匀性评价、正确评价迭层土强度、插桩过浅时进行平台抗滑移性评价等,可有效减少失误。
