Hourglass-shaped marine engineering floating structures

Abstract

The invention discloses an hourglass-shaped marine engineering floating structure, which has an upper structure body that is a circular truss or a prism and a lower structure that is a perfect circular truss or a truss; in a combined state, the area of ​​the upper structure is The smaller bottom surface is fixedly connected to the bottom surface of the lower structure with a smaller area to form a connection surface; the axes of the upper structure and the lower structure are on the same straight line, and the bottom of the upper structure with a larger area is a floating structure The upper deck of the structure, the bottom of the lower structure with a larger area is the lower bottom plate of the floating structure under water; the connecting surface is the fully loaded waterline surface of the floating structure. Compared with the traditional drilling platform, it has a larger oil storage space, and compared with the traditional oil storage ship type FPSO, it has better motion performance. Therefore, the marine engineering floating structure proposed by the present invention is beneficial to the multi-functional integration of drilling, exploitation, storage, production, processing and export of large-scale oil and gas in various sea areas, and has good economic benefits.

Description

technical field [0001] The invention relates to patent classification B63 Ships or other water craft; Ship-related equipment B63B Ships or other water craft; Marine equipment B63B35 / 00 Ships suitable for special purposes or similar floating structures B63B35 / 44 Floating structures, water Tanks, water drilling platforms or water workshops, such as those carrying oil-water separation equipment. Background technique [0002] In the field of marine engineering, no matter from the economics of oil and gas exploitation in shallow waters, or from the necessity of oilfield development in deep waters and ultra-deep waters, it is necessary to use floating structures of corresponding scale. In addition, with the trend of multi-functional integration and deep-sea development, floating structures not only need to have sufficient tank capacity and deck area to carry oil, gas and equipment necessary for mining and production, but also need to have good motion performance to withstand The ...

AI Technical Summary

Problems solved by technology

However, the hydrodynamic performance of this ship-type floating body has the following limitations and deficiencies: the natural period of the heave of the traditional ship-type FPSO is difficult to stay away from the area where the wave energy is concentrated, and the amplitude of the heave motion is large

However, at the same time, its performance has disadvantages: the heaving motion of the floating body is relatively large, which is easy to cause vortex-induced vibration, the deck area is small, the living and working spaces are too close, and it is not conducive to the separation of dangerous areas and non-dangerous areas, etc.
