Deep water column type export buoy

Abstract

A deep-water column-type export buoy, comprising: a buoy main body, a turntable arranged on the buoy main body, the turntable is connected with the buoy main body through a rotating bearing, the buoy main body is a deep-draft column structure, and the bottom of the column-type buoy main body is A fixed ballast tank is provided, and a ballast water tank is provided near the waterline at the top; at the same time, the natural period of the rolling, pitching and heaving motion of the main body of the column type buoy is greater than 20 seconds, so as to stay away from the main wave energy area . The invention has a wide range of applications, and can serve not only in sea areas with harsh environmental conditions, but also in sea areas with good conditions; moreover, it greatly improves the movement performance of the export buoy, and realizes long-distance external buoys under severe sea conditions in deep water sea areas. At the same time, the design difficulty of the external oil pipeline and the mooring system is greatly reduced, and the cost of the external transportation and mooring system can be saved.

Description

technical field [0001] The invention relates to a crude oil export device, in particular to a deep-water column-type export buoy suitable for crude oil export on a floating platform in a deep-water harsh environment. It belongs to the field of marine engineering. Background technique [0002] Crude oil transportation is an important part of offshore oilfield development, which directly affects the economic benefits of the entire oilfield development. So far, there are two modes of exporting offshore crude oil, one is: exporting by submarine pipeline; the other is: exporting by offshore shuttle tanker. [0003] Although the use of submarine pipelines to transport crude oil will not be affected by the environmental and climatic conditions to stop the production of oil fields, and the operation and management costs of the pipelines are also relatively low, but the investment costs for the construction of submarine pipelines are quite high, and there are greater investment risk...

AI Technical Summary

Problems solved by technology

Its disadvantage is that since the natural period of movement of the external buoy (in design, mainly considering roll, pitch and heave), is generally about 10 seconds, which is close to the main energy area of ​​the wave, so its movement performance is very Poor, the design requirements of external oil pipelines and mooring systems are very high, and cannot be applied to sea areas with relatively harsh environmental conditions and large waves, such as: South China Sea, North Sea, Brazil and other sea areas in the world
