Abstract
The utility model discloses a supporting rod of an offshore platform positioning column. The supporting rod comprises a pressure-bearing column, wherein the two ends of the pressure-bearing column are respectively provided with a second face plate used for enlarging the contact surface between the pressure-bearing column and a frame body. According to the supporting rod of the offshore platform positioning column, the second face plates are arranged at the two ends of the pressure-bearing column to enlarge the contact surface between the supporting rod and the frame body, so that the pressure at the position of contact between the supporting rod and the frame body is reduced, and the offshore platform positioning column can bear higher pressure.
Description
Technical field
The utility model relates to ocean engineering and ship building technical field, relates in particular to a kind of strut bar of offshore platform registration mast.
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 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 general 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 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, in order to alleviate the weight of registration mast, therefore adopt frame structure, frame structure inside is provided with and supports, general pillar stiffener and the area of contact of framework are less, therefore the pressure between pillar stiffener and framework is excessive, still cannot bear larger pressure.
Summary of the invention
The utility model is not enough for prior art, and a kind of strut bar of offshore platform registration mast is provided, and the strut bar of this offshore platform registration mast has increased the contact surface between strut bar and framework, thereby makes registration mast can bear higher pressure.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of strut bar of offshore platform registration mast, comprise pressure-bearing post, described pressure-bearing post two ends be provided with for increase and framework between the second panel of contact surface.
In technique scheme, preferred, between described pressure-bearing post and described the second panel, be provided with some reinforced ribs.
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 increases the area between strut bar and framework by the second panel being set at pressure-bearing post two ends, thereby reduce the pressure of strut bar and framework contact position, thereby make registration mast can bear larger pressure.
