Abstract
The utility model provides an asymmetric semi-submersible type ocean platform. The asymmetric semi-submersible type ocean platform is structurally composed of an upper layer structure, stand columns, a main buoyancy tank, a front buoyancy tank and a rear buoyancy tank. The top of the main buoyancy tank, the top of the front buoyancy tank and the top of the rear buoyancy tank are directly connected to the bottom of the upper layer structure through at least two stand columns, and the front buoyancy tank and the rear buoyancy tank are arranged on the same side of the main buoyancy tank. Different from a traditional symmetrical structure, the whole asymmetric semi-submersible type ocean platform can be effectively prevented from conducting spiral heaving motion through wave interference of the front buoyancy tank and the rear buoyancy tank on one side of the main buoyancy tank during motion in waves, and hydrodynamic performance and stability of the asymmetric semi-submersible type ocean platform are further improved.
Description
Technical field
The utility model relates to Naval Architecture and Ocean Engineering technical field, especially relates to a kind of asymmetric semi-submersible offshore platform.
Background technology
Semi-submersible offshore platform is comprised of platform body, column and lower body or buoyancy tank conventionally.In addition, between lower body and lower body, column and column, column and platform body, also have some supports to be connected with diagonal brace.Platform is provided with drilling machinery equipment, equipment and accommodation etc., for well borer's effect.Platform body exceeds water surface certain altitude, in order to avoid the impact of wave.Lower body or buoyancy tank provide main buoyancy, are submerged under water to reduce the disturbance force of wave.The column being connected between platform body and lower body, has the section of small-waterplane-area, and the suitable distance of being separated by between column and column, to guarantee the stability of platform.
Semi-submersible drilling unit is because lower body is all immersed in water, and the amplitude of its rolling and pitching is all very little, but what have considerable influence is heaving.Existing conventional semi-submersible offshore platform is all to adopt symmetrical structure, but symmetrical structure form easily makes semisubmersible platform produce spiral heaving.
Utility model content
The purpose of this utility model is exactly in order to develop a kind of asymmetric semi-submersible offshore platform, causes the deficiency of the spiral heaving of semisubmersible platform to solve symmetrical structure.
The purpose of this utility model can realize by following scheme.
A kind of asymmetric semi-submersible offshore platform that the utility model provides, by superstructure, column, main buoyancy tank, front side buoyancy tank and rear side buoyancy tank, formed, the top of main buoyancy tank, front side buoyancy tank and rear side buoyancy tank is directly connected to superstructure bottom by least two columns, and front side buoyancy tank and rear side buoyancy tank are arranged in the same side of main buoyancy tank.
Main buoyancy tank, front side buoyancy tank and rear side buoyancy tank have identical draft.
The molded breadth of front side buoyancy tank and rear side buoyancy tank is consistent, and main buoyancy tank molded breadth is front side buoyancy tank and rear side buoyancy tank molded breadth 1.5-2 times.
The beneficial effects of the utility model are: different from traditional symmetrical structure, asymmetric semi-submersible offshore platform of the present utility model, by the front side buoyancy tank of main buoyancy tank one side and the wave of rear side buoyancy tank, disturb and can effectively prevent that whole platform from producing spiral heaving when the Motion Waves, further improved hydrodynamic performance and the stability performance of semisubmersible platform.
Accompanying drawing explanation
Fig. 1 is the asymmetric without stull semi-submersible offshore platform schematic diagram of the utility model-embodiment.
In figure, 1. superstructure, 2. column, 3. main buoyancy tank, 4. front side buoyancy tank, 5. rear side buoyancy tank.
The specific embodiment
Below, by accompanying drawing and exemplary embodiment, the utility model is specifically described.Yet, should be appreciated that element, structure and the feature described in one embodiment also can be attached in other embodiment valuably in the situation that further not narrating.
As shown in Figure 1, the asymmetric semi-submersible offshore platform that the utility model provides consists of superstructure 1, column 2, main buoyancy tank 3, front side buoyancy tank 4 and rear side buoyancy tank 5.The top of main buoyancy tank 3, front side buoyancy tank 4 and rear side buoyancy tank 5 is directly connected to superstructure 1 bottom by least two columns 2, and front side buoyancy tank 4 and rear side buoyancy tank 5 are arranged in the same side of main buoyancy tank 3.
Main buoyancy tank 3, front side buoyancy tank 4 and rear side buoyancy tank 5 have identical draft.
The molded breadth of front side buoyancy tank 4 and rear side buoyancy tank 5 is consistent, and main buoyancy tank 3 molded breadths are front side buoyancy tank 4 and rear side buoyancy tank 5 molded breadths 1.5-2 times.
When the utility model is used as oil-gas field production facility, in superstructure 1, oil gas treatment facility etc. is installed, utilize multi-buoy mooring system to carry out offshore location, oil gas is by completing conveying by seabed to many standpipes of this platform, defeated outside standpipe again after this platform processes is qualified.
Should be understood that; although the utility model is described by above-described embodiment; yet the utility model can also have other numerous embodiments; do not departing under the prerequisite of the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
