| Abstract: | To overcome shortcomings of the existing platforms, based on detailed studies on many factors affecting the comprehensive performance of the semisubmersible platform, a new deepsea floating platform named jackup combined semisubmersible multifunction platform (JCSM) is developed, incorporating the advantages of the jackup platform with the deck being lifted and lowered easily, and has obtained independent intellectual property rights. Through integrating the advantages of the jackup with the semisubmersible platform, and optimizing the details of the topological structure, the JCSM obtains large stability margin and excellent motion performance. Therefore, it well suits wet tree, dry tree production or the combination of the both. Meanwhile, it possesses a variety of attractive functions such as drilling, early production, workover, oil and gas processing, oil storage and unloading, etc. Moreover, numerical analysis of the stability and motion of a JCSM example is carried out, verifying the superiority of the new platform''s performance. This study provides a new choice for the future development of offshore oil and gas fields, and has reference and guiding significance for the development of creative floating platforms. |
