Description
Technical field
The present invention relates to ocean engineering and shipbuilding technical field, relate in particular to a kind of offshore platform.
Background technology
Along with the scientific and technological level development, the mankind deeply visit and get resource to ocean gradually, and must need to arrange offshore platform when resource is got in spy at sea, and offshore platform mainly comprises fixed offshore platform and floating offshore platform.
Fixed offshore platform immobilizes position within whole useful life period, 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 the 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.
The 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, claim 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.Floating offshore platform commonly used is that bottom-supported platform (also claiming the floatable platform) is multiplex in 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, and is middle with 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 the seabed certain depth, thereby hull bottom is held out 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 multiplex in the larger marine site of the depth of water, 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 the pontoon formula is more conducive to navigation, therefore the newly-built semisubmersible platform of boat certainly, adopts two pontoon formulas.Be in partially surfaced condition during this platform operation, adopt anchoring location or dynamic positioning.After operation, discharge the water in ballast tank, float up to the towage water line, can receive the anchor displacement.The minority semisubmersible platform of past construction has the function of bottom-sitting type concurrently, also can be located seabed in phytal zone and carry out operation.4. boat form platform (being drill ship) is to add a job platform on common boats and ships, and boats and ships have dividing of monomer and binary, generally can, from boat, adopt anchoring to locate or dynamic positioning during operation.Present transportable floating platform is applied at most 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 that inserts behind seabed, and because reference column length is longer, so the weight of reference column is larger, therefore the barge during floating state need to have very large buoyancy guarantee barge to float on the surface, therefore very high to the manufacturing requirement of barge, perhaps can only be furnished with shorter reference column, make jack-up unit to use in more shallow marine site.
Summary of the invention
