Description
Technical field
The utility model relates to ocean engineering and shipbuilding technical field, relates in particular to a kind of offshore platform.
Background technology
Along with scientific and technological level 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 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 platform, and it is that the needs that must often change place for adapting to the operations on the sea 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 unit adaptation depth of water scope is larger, is a barge when floating state, and its four sides are equipped with some column types or truss framed leg, with gear, tooth bar or hydraulic mechanism, 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 unit of box-shaped mat, not with the title pitching pile jack-up unit 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, middle standing pillar or truss three parts, consists of.Lower floor's float structure divides again two kinds of pontoon formula and floating box types, and pontoon formula is more conducive to navigation, therefore the newly-built semisubmersible platform of boat certainly, adopts two pontoon 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 water line, can receive anchor displacement.The minority semisubmersible platform of past construction has the function of bottom-sitting type concurrently, also can in phytal zone, be located seabed and carry out operation.4. boat form platform (being drill 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 natural gas exploration.The complex structure of traditional jack-up unit, operate very inconvenient, reference column is all generally solid, reference column is solid mainly considers the anti-pressure ability inserting behind seabed, and because reference column length is longer, so the weight of reference column is larger, therefore barge during floating state 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 reference column, jack-up unit can only be used in more shallow marine site.
