Abstract
The invention relates to a semi-submersible platform with a novel upright post structure. The semi-submersible platform comprises an upper platform and a lower floating body, wherein the lower floating body at least comprises a group of pontoons symmetric to one another; a second support is connected among various pontoons; at least one group of upright posts symmetric to one another are connected between the upper platform and the lower floating body; various upright posts are connected by a first support; the section areas of the upright posts are gradually increased from bottom to top; an included angle alpha being not greater than 90 degrees is formed between any bus at the periphery of each upright post and a waterline plane; the section of each upright post is designed to be octagonal, so that an acting force, borne by waves, of the semi-submersible platform in the waves can be effectively reduced, the stress in each wave direction is uniform and the motion is reduced; the cross section area of the upright posts is gradually increased from bottom to top, and thus the restoration of moment of the semi-submersible platform when tilting by wind wave impact is facilitated to be enhanced; in addition, the included angle alpha of not greater than 90 degrees is formed between the bus of each upright post and the waterline plane, so that the climbing of the waves before the upright posts can be reduced, further the impact of the waves on a bottom structure of the platform is reduced, and the reliability of the structure of the semi-submersible platform disclosed by the invention is improved. The semi-submersible platform is suitable for severe marine environments.
Description
Technical field
The present invention relates to floating platform on sea, relate in particular to a kind of half latent type platform severe marine environment, that there is Novel upright post structure that is applicable to.
Background technology
Half latent type platform also claims column stable platform, half structure of diving type platform forms by lower buoyancy aid, column and upper brace, and its wind loading rating is strong, has good stability, adapt to depth of water scope wide, carrying capacity is large, is widely used in probing, the mining operations of marine oil and gas resource.Existing half horizontal section of diving type platform structure central post is designed to square or circular, and because marine environment of living in is comparatively severe, it is uncertain that wave carrys out flow path direction, and wave constantly impacts platform structure, and upwards climbs along column, impacts and the wet upper brace of punching.When column cross section is while being square, the type platform motion in wave of should half diving is larger, is subject to the application force of wave larger; In the time that column cross section is circle, the less stable of the type platform of should partly diving, when platform is subject to wind-force and wave action to produce canting, countermoment is little.
Summary of the invention
The applicant is for above-mentioned existing issue, be studied improvement, a kind of half latent type platform with Novel upright post structure is provided, not only ensure stability of the present invention in wave, reduce wave force, the application force that simultaneously also ensures all directions wave is even, has reduced motion of the present invention, is applicable to severe marine environment operation.
The technical solution adopted in the present invention is as follows:
There is half of the Novel upright post structure type platform of diving, comprise upper brace, lower buoyancy aid, described lower buoyancy aid at least by one group each other symmetrical floating drum form, between each floating drum, connect the second support; At least one group each other symmetrical column be connected between described upper brace and lower buoyancy aid, between each column, by the first support and connection, the sectional area of described column increases progressively from the bottom to top, the arbitrary bus of column periphery is not more than the angle α of 90 ° with waterplane formation.
Its further technical scheme is:
The shape of cross section of column is octagon;
Described column is and is arranged vertically between upper brace and lower buoyancy aid;
Described the first support and the second structure supporting are identical, and described the first support and the second shape of cross section supporting are circular or square;
Be positioned at returning apparatus superstructure on upper brace;
Described first supports and is lateral arrangement between two columns, and described second supports and be and be longitudinally arranged between two floating drums.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy to use, by arranging the first support and the second support, has effectively improved bulk strength of the present invention and rigidity, reduces platform and is out of shape in wave.Column Cross section Design is octagon, can effectively reduce the application force of the suffered wave of the present invention in wave, makes each wave to stressed even, has reduced motion of the present invention.Column cross-section area increases progressively from the bottom to top, be conducive to increase the recovery of the present invention's moment in the time being subject to stormy waves canting, and owing to forming the angle α that is not more than 90 ° between riser bus bar and waterplane, can reduce wave climbs before column, thereby reduce the impact of wave to platform bottom construction, thereby, improve reliability of structure of the present invention, make it be applicable to severe marine environment.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, a kind of half latent type platform with Novel upright post structure, comprises upper brace 2, and lower buoyancy aid, is positioned at returning apparatus superstructure 1 on upper brace 2.Lower buoyancy aid at least by one group each other symmetrical floating drum 4 form, between each floating drum 4, connect the second support 6; At least one group symmetrical and be vertical column 3 and be connected between upper brace 2 and lower buoyancy aid each other, between each column 3, supporting 5 by first connects, the lateral cross section area of column 3 is upwards and increases progressively to the one end being connected with upper brace 2 by the one end being connected with lower buoyancy aid, and the shape of cross section of column 3 is octagon.The column arbitrary bus of 3 periphery and waterplane form the angle α that is not more than 90 °.The structure of the first support 5 and the second support 6 is identical, and the shape of cross section of the first support 5 and the second support 6 is circular or square.Above-mentioned first supports and 5 is lateral arrangement between two columns 3, and second supports 6 is and is longitudinally arranged between two floating drums 4.Above-mentioned floating drum 4 also can be replaced by caisson.
As shown in Figure 3, after central post 3 of the present invention contacts with waterplane A, lower buoyancy aid, for the utility model provides welfare, has ensured the load of middle and upper part of the present invention platform 2.In the situation that marine environment is severe, wave B upwards climbs to column 3 surfaces, because column 3 cross-sectional areas increase progressively from the bottom to top, be conducive to increase the recovery of the utility model moment in the time being subject to stormy waves canting, and owing to forming the angle α that is not more than 90 ° between riser bus bar and waterplane, even if wave B and column 3 Surface Contacts and climb, also can be subject to self gravitation effect and fragmentation reduces thereby play the effect that wave B climbs before column.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
