Abstract
The utility model discloses a positioning column of an offshore platform. The positioning column comprises a column type steel structure frame body, wherein a plurality of supporting rods are arranged in the frame body, racks are arranged on two opposite outer side faces of the frame body, by arranging the positioning column to be composed of the frame body and the supporting rods, the weight of the positioning column is lowered, the longer positioning column can be arranged under the condition of not improving the floating force of a barge, and the positioning column can be used in a deeper sea area.
Description
Technical field
The utility model relates to ocean engineering and ship building technical field, relates in particular to the registration mast of offshore platform.
Background technology
[0002] along with state-of-art development, the mankind deeply visit and get resource to ocean gradually, and when resource is got in spy, must need to arrange offshore platform at sea, and offshore platform mainly comprises fixed offshore platform and floating offshore platform.
Fixed offshore platform immobilizes position within whole useful life period, and its form has a formula, guy wire formula and gravity type boat davit etc.Stake formula platform consists of cushion cap and pile foundation.Pile foundation has the kinds such as timber, piling bar and reinforced concrete pile, while constructing, it is squeezed into seabed, and cushion cap has been installed on it.Guy wire formula platform claims again lashing tower platform, and a prefabricated head tower is placed on seafloor foundation piece, with cable wire, along different directions grappling tension, forms.Gravity platform is to occupy stably on the firm stratum of seabed by the weight of platform self, and the ability of resisting storm and wave attack is strong.
Floating offshore platform is a kind of large-scale buoyancy aid, and what have can move, and what have does not move.Transportable floating platform, claims again movable decking, and it is that the needs that must often change place for adapting to the marine operation such as exploration, construction, maintenance grow up.Conventional floating offshore platform be bottom-supported platform (also claiming floatable platform) to be used for the more shallow ，Qi top, waters of the depth of water be spar deck, bottom is the buoyancy tank that doubles as mat, middle for column or truss support.During operation, toward the interior water filling of buoyancy tank, make it to be located seabed; After operation, water in case is extracted out, platform relies on the buoyancy of self to rise.2. jack-up platform adaptation depth of water scope is larger, is a barge when floating condition, and its four sides are equipped with some column types or truss framed leg, with gear, tooth bar or hydraulic gear, control lifting.During operation, put down spud leg and insert seabed certain depth, thereby hull bottom is held out to the water surface, become spar deck.After operation, fall hull, pull up spud leg, can the extremely new place of towage.Spud leg bottom is with the title mat jack-up platform of box-shaped mat, not with the title pitching pile jack-up platform of mat.3. semisubmersible platform is used for the marine site that the depth of water is larger, also upper strata spar deck, lower floor's float structure, B-pillar or truss three parts, consists of.Lower floor's float structure divides again two kinds of lower hull formula and floating box types, and lower hull formula is more conducive to navigation, therefore the newly-built semisubmersible platform of boat certainly, adopts two lower hull formulas.During this platform operation, in partially surfaced condition, adopt anchoring location or dynamic positioning.After operation, discharge the water in ballast tank, float up to towage floating line, can receive anchor displacement.The minority semisubmersible platform of past construction has the function of bottom-sitting type concurrently, also can in shoal water zone, be located seabed and carry out operation.4. boat form platform (being drilling ship) is on common boats and ships, to add a job platform, and boats and ships have dividing of monomer and binary, generally can, from boat, adopt anchoring to locate or dynamic positioning during operation.Current transportable floating platform should be with the most use in submarine oil and gas prospecting.The registration mast of tradition jack-up platform is all generally solid, registration mast is solid mainly considers the pressure resistance inserting behind seabed, and because registration mast length is longer, therefore the weight of registration mast is larger, therefore barge during floating condition need to have very large buoyancy guarantee barge to float on the surface, therefore very high to the manufacture requirement of barge, or can only be furnished with shorter registration mast, jack-up platform can only be used in more shallow marine site.
Summary of the invention
The utility model is not enough for prior art, and the registration mast of offshore platform is provided, and this offshore platform is lightweight, can just can be furnished with the registration mast more lengthening in the situation that do not improve the floating force of barge, can in the marine site of more deepening, use.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The registration mast of offshore platform, comprises a pillar steel structure framework, is provided with some strut bars in described framework, on relative two lateral surfaces of described framework, is provided with tooth bar.
In technique scheme, preferred, in described framework, be also provided with the 3rd panel, on described the 3rd panel, be provided with some third through-holes, described strut bar is located in described third through-hole.
The utility model compared with prior art, there is following beneficial effect: the utility model is by being arranged to registration mast the quality that framework and strut bar have alleviated registration mast, can just can be furnished with the registration mast more lengthening in the situation that do not improve the floating force of barge, can in the marine site of more deepening, use.
Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of registration mast.
Fig. 2 is registration mast inner structure schematic diagram.
Fig. 3 is the structural representation of strut bar.
Fig. 4 is that registration mast is arranged on the schematic diagram on barge.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 4, the registration mast of offshore platform, comprise a pillar steel structure framework 21, in described framework 21, be provided with some strut bars 22, described some strut bars 22 comprise pressure-bearing post 221, described pressure-bearing post 221 two ends be provided with for increase and described framework 21 between the second panel 222 of contact surface, on relative two lateral surfaces of described framework 21, be provided with tooth bar 23.Make solid registration mast originally into structure that framework 21 adds strut bar 22 weight of registration mast is reduced, thereby make the barge 1 of equal size can carry longer registration mast, thereby make the barge 1 of formed objects can be in darker marine site work.
Between described pressure-bearing post 221 and described the second panel 222, be provided with some reinforced ribs 223, the second panel 222 be set and make the area of contact between pressure-bearing post 221 and framework 21 larger, thereby make local pressure less, promote bearing capacity.
Convenient location when strut bar 22 is installed, is therefore also provided with the 3rd panel 24 in described framework 21, on described the 3rd panel 24, is provided with some third through-holes 241, and described strut bar 22 is located in described third through-hole 241.
