This paper studies the current available options forfloating production platforms in developing deepwater oil fieldsand the potential development models of future oil and gasexploration in the South China Sea. A detailed review of currentdeepwater platforms worldwide was performed through theexamples of industry projects, and the pros and cons of eachplatform are discussed. Four types of platforms are currently usedfor the deepwater development: tension leg platform, Spar,semi-submersible platform, and the floating production systemoffloading. Among these, the TLP and Spar can be used for dry treeapplications, and have gained popularity in recent years. The drytree application enables the extension of the drilling application forfixed platforms into floating systems, and greatly reduces the costand complexity of the subsea operation. Newly built wet treesemi-submersible production platforms for ultra deepwater are alsogetting their application, mainly due to the much needed payloadfor deepwater making the conversion of the old drillingsemi-submersible platforms impossible. These platforms have beenused in different fields around the world for different environments;each has its own advantages and disadvantages. There are manychallenges with the successful use of these floating platforms. A lotof lessons have been learned and extensive experience accumulatedthrough the many project applications. Key technologies are beingreviewed for the successful use of floating platforms for fielddevelopment, and potential future development needs are beingdiscussed. Some of the technologies and experience of platformapplications can be well used for the development of the SouthChina Sea oil and gas field. 相似文献

动力定位系统在船舶和海洋工程有着大量的应用,特别是在深水石油开发钻井平台中成为必备的关键设备。海洋钻井平台在钻井作业过程中要求其不受海洋气象环境的影响,保持在一个相对确定的海面位置上。早期浅水浮式钻井平台采用锚定位的方式可以胜任该项作业要求,但随着水深的增加,特别在大于1000米水深时,从技术和经济角度考虑已不能适应实际的需要。本文集中介绍动力定位系统的组成和系统配置,为以后的动力定位系统设计起到一定的借鉴作用。 相似文献
