Abstract
The utility model discloses a positioning column for an offshore platform. The positioning column for the offshore platform comprises a column type steel structure frame; a semispherical projection is arranged at the bottom of the frame; a plurality of fins are extended on the lateral side of the semispherical projection; the fins play a role in guiding and enable positioning to be easy when the positioning column is extended into the seabed.
Description
Technical field
The utility model relates to ocean engineering and ship building technical field, relates in particular to a kind of registration mast of offshore platform.
Background technology
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 is that bottom-supported platform (also claiming floatable platform) is used for the more shallow waters of the depth of water, and its top is spar deck, and bottom is the buoyancy tank that doubles as mat, middle by 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 complex structure of traditional jack-up platform, operate very inconvenient, registration mast 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 to the manufacture of barge, require very high, or can only be furnished with shorter registration mast, jack-up platform can only be used in more shallow marine site, and general common registration mast to penetrate seabed more difficult, contrast locating is more difficult.
Summary of the invention
The utility model is not enough for prior art, a kind of registration mast of offshore platform is provided, the weight of this registration mast is less, 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, and can be relatively easy to penetrate seabed and be fixed, convenient location.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of registration mast of offshore platform, comprise a pillar steel structure framework, described framework bottom is provided with hemispherical projections, and described hemispherical projections side extends some fins.
In technique scheme, preferred, in described framework, be provided with some strut bars, on relative two lateral surfaces of described framework, be 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, has following beneficial effect:
The utility model registration mast bottom is provided with hemispherical projections and fin, make registration mast stretch into when marine more easily location, boring adopts they sup-port, having reduced weight provides cost savings, and make the barge of formed objects can carry longer strut bar, the marine site work that can more deepen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional configuration schematic diagram of registration mast.
Fig. 3 is the structural representation of strut bar.
Fig. 4 is that registration mast is arranged on the structural representation 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, a kind of registration mast of offshore platform, in order to alleviate quality, 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, between described pressure-bearing post 221 and described the second panel 222, be provided with some reinforced ribs 223, for convenient location when the interior installation strut bar 22 of framework 21, in described framework 21, be also provided with the 3rd panel 24, on described the 3rd panel 24, be provided with some third through-holes 241, described strut bar 22 is located in described third through-hole 241, on relative two lateral surfaces of described framework 21, be provided with tooth bar 23, described tooth bar 23 is fixed registration mast with the lifting mechanism on barge, described framework 21 seabed interaction places, bottom are provided with hemispherical projections 25, described hemispherical projections 25 sides extend some fins 26, arrange and when hemispherical projections 25 and fin 26 make registration mast seabed interaction, easily stretch into seabed, and play directional tagging in the process stretching into seabed at registration mast 2.
