Marine engineering facilities are a general term for various facilities and devices constructed for marine development. An offshore oil (gas) field production platform (offshore platform for short) is taken as one of offshore engineering facilities, is an offshore drilling and production facility for offshore oil and gas development, has the main functions of oil and gas extraction, pretreatment, oil and gas output and the like, and comprises an upper module and a supporting structure (such as a fixed structure, a floating structure and the like) which comprises a guide pipe frame, a gravity base supporting structure and a compliant tower type supporting structure; floating structures include FPSO hull structures, semi-submersible support structures, and the like.
With the development of ocean development and ocean space utilization engineering, offshore oil (gas) field production platform supporting structures have various forms of ocean structures, and therefore offshore oil (gas) field production platforms which take the structures as main characteristics are also provided, and mainly comprise traditional jacket fixed platforms, compliant platforms, traditional tension leg platforms, miniature tension leg platforms, column barrel type platforms, semi-submersible platforms, floating production oil storage and oil discharge devices and underwater production facilities.
It can be seen that the current installation technology of the marine drilling and production platform requires that structures are installed on the seabed, and most of the structures need to be extended to the sea level. This obviously does not meet the requirements of shallow water navigation areas and military control areas for prohibiting navigation of obstacles. Resulting in the inability to produce large numbers of fields located on waterways and in military control areas.
