Abstract

The invention discloses an offshore platform sailing rapidly, and belongs to the field of shipbuilding, ocean engineering and oil exploitation. The on-water platform part is like that of other offshore platforms, and use functions can be met; the underwater part consists of two large-size submarine type buoyancy tank engine rooms in parallel; the buoyancy tank engine rooms are connected in a regular intersecting parallel manner by two connecting beams; four support columns for supporting the offshore platform are arranged on four joints of the regular intersecting parallel shape, and then the offshore platform can be supported to sail rapidly in ocean; two small-size olive engine rooms are arranged in the middle of the connecting beams; the small-size olive engine rooms can rotate for 360 degrees so as to finely adjust the position and the direction of the offshore platform; the underwater buoyancy tank engine rooms, the connecting beams and the support columns, except engine cabs, an adjusting water tank, pipelines and pedestrian paths, are all divided into zones and grids, and are filled with foamed polyphenyl plastic, so that no surplus space for water permeation is available; the adjusting water tank is divided into four independent parts according to the quadrant so as to adjust balance of the offshore platform.

Description

Can the offshore platform of quick sailing

Technical field: belong to shipbuilding, ocean engineering, field of petroleum exploitation.

Background technology: nowadays, marine geologic prospect, offshore oil exploitation, use offshore platform more, but, offshore platform volume is big, Heavy Weight, Mobile slow, also often topple over accident, this just requires that offshore platform can have oneself quick sailing at sea, and support platform is difficult to be destroyed under water, platform It is difficult to the function toppled over.

Summary of the invention: build an offshore platform, platform upper, as other platforms, completes function and task that various offshore platform should complete； Platform lower, has four support columns to couple with underwater pontoons, and buoyancy tank is made up of two submarine pattern underwater pontoons engine rooms, two engine rooms by Two linking beams are connected into well subtype, and four nodes of well subtype couple with four support columns of platform, constitute offshore platform and suspend and quick sailing Basic function；The middle part of two linking beams, if a little bit smaller underwater wheel cabin of two olive-types, two little engine rooms can 360 degree of freedom Turn to, platform can be made to do small movement or rotation；Underwater pontoons formula engine room and linking beam, support column, be the main buoyancy source of offshore platform, In addition to engine room, passage, regulating tank pipe, whole subregion lattices, filling-foam polyphenyl plastics, there is no the space that can intake under water, prevent it from breaking After Huai permeable, the safety of crisis offshore platform.Its specifically used function, operation sequence are assumed as follows:

One is, quick sailing: after receiving marine execution task, be transferred in the underwater wheel cabin of two olive-types identical with main floating box type engine room Direction, by regulating tank, makes platform keep suitable distance with sea, starts two main buoyancy tank turbines, quickly hurry to task ground, when needing to turn to, Strengthening or reduce the rotating speed of one of them turbine, the electromotor of double buoyancy tanks, power is big, and the speed of a ship or plane is the highest, the fastest, and the water surface seems a heaviness Offshore platform, be horsepower and the speed having two submarines in fact, simply support huge platform gravity, the least and sea by four support columns Rub, decrease resistance, the offshore platform of quick sailing, the most unusual, special purposes could be sent.

Two are, fine position: after arriving at, and determine position, direction, ocean current etc., open the wheel of the small underwater engine room of two olive-types Machine, trim locations and direction so that it is be accurately positioned, anchor chain of dishing out is fixed.

Three are, safety and stability: first, floating box type engine room under water and linking beam, arrange in well subtype, corresponding with offshore platform balance, four Support column is circular cross-section, is the linked system of platform and buoyancy tank, and except supported weight, outside keeping stablizing, or platform couples with buoyancy tank, linking beam Passage, staircase, lift well, the passage of pipeline etc.；Secondly, the cumulative volume of the underwater portion such as floating box type engine room, linking beam, is by whole Individual offshore platform gross weight, the weight configuration that later may increase, regulating tank water-filling, more than the height of gravity formation, be made by possible buoyancy Its offshore platform reaches design height, and regulating tank is divided into four independent parts by quadrant, to regulate the balance of offshore platform；Again, will under water Floating box type engine room, linking beam, support column etc., in addition to engine room, regulating tank, passage, be all divided into district's lattice, filling-foam polyphenyl plastics, Making it not have the space that can intake, underway sets partition and the door that blocks water, and closes this sect, just can open next sect so that it is underwater pontoons, i.e. The most permeable, local is hit rotten, also will not topple over or sink；4th, owing to being affected by marine tide, wind-force, ocean current etc., moment detection sea is flat The displacement of platform or displacement trend, during as needed trim locations, start the small-sized turbine of two olive-types, moves to the direction required, finely tunes offshore platform Position, regulate and fix anchor chain.

Accompanying drawing illustrates: Fig. 1 be can the offshore platform side view of quick sailing, the signal each portion of offshore platform relevant position on facade, such as submarine The relevant position in tower crane, boring tower, Su Ban building etc. on formula buoyancy tank engine room, engine room, propeller, support column, platform, airplane parking area, platform；Figure 2 be can navigating power and the floating system plane graph of offshore platform of quick sailing, illustrate two parallel submarine formula buoyancy tank engine rooms, well subtypes Linking beam, four support, two can the relevant position of 360 degree of little olive-type engine rooms turned to, illustrate floating box type engine room, linking beam section Structure, indicates regulating tank, walkway, the position etc. of foaming polyphenyl plastics.

Detailed description of the invention: this invention is introduced to ocean machinery, offshore oil enterprise, but can the offshore platform oneself of quick sailing for producing Fine setting offshore location, the offshore platform of the anti-permeable safety toppled, propose a scheme, for proving, test, implementing.

Claims

1. the underwater portion of offshore platform, the horizontal well font structure being made up of buoyancy tank engine room and the continuous beam of two submarine formulas, at well word On four nodes of type, being connected by four support columns with offshore platform, balanced support offshore platform, the buoyancy tank wheel of the submarine formula that two are arranged in parallel Cabin, is equipped with the electromotor matched with gross tonnage, design speed, it is possible to hold in the palm offshore platform, smoothly with design speed, and quick sailing, This is the claim of patent applicant.

Platform underwater portion the most at sea, between two parallel buoyancy tank engine rooms, is connected into groined type by two linking beams, at well subtype Middle part, set respectively two can 360 degree of little olive-type engine rooms turned to, underwater well font buoyancy tank can be made to move or rotate, this is patent Shen The claim asked someone.

The underwater portion of platform the most at sea, is made up of floating box type engine room, linking beam, support column, and this is the main buoyancy of offshore platform Source, in addition to engine room, passage, regulating tank pipe, ventilation ventilating water pipe, whole subregion lattices, filling-foam polyphenyl plastics, do not have under water to enter The space of water, permeable after preventing its underwater pontoons local destroyed, the safety of crisis offshore platform, it is simply that by buoyancy tank hydrospace part, fill and send out Bubble polyphenyl plastics, prevent permeable, and this is the claim of patent applicant.
