Description

A kind of self propelled barge and operational method thereof for the floating holder of jacket chunk
Technical field
The present invention relates to a kind of barge and operational method thereof, particularly about a kind of self propelled barge and operational method thereof for the floating holder of jacket chunk.
Background technology
Floating holder method is one of main method of marine jacket chunk installation.When carrying out sea floating holder operation, first barge is lifted upper chunk and is sailed into by jacket notch, until upper chunk be positioned at jacket structure directly over, now barge carries out interim anchoring location and by adjusting ballast, hull is slowly sunk, until jacket fulcrum and upper chunk fulcrum achieve a butt joint, barge reclaims anchoring system afterwards, and has exited floating holder operation from jacket notch.
The at present floating conventional mode of holder method is the floating holder of single ship, which has the defect of following several respects: first, due to the barge beam large (conventionally 30 meters of left and right), for making its smooth conducting pipes frame, what jacket notch must design is very wide very dark, makes like this span between upper chunk fulcrum very large, for guaranteeing that chunk possesses enough structural strengths, chunk weight will significantly increase, and steel using amount during manufacture can obviously promote; In addition, because jacket notch belongs to large hatch frame, so jacket structure itself both had certain design difficulty, also can cause the further lifting of steel using amount.Secondly, barge hull is longer, and stand under load area is larger, for avoiding hull and jacket top structure to collide, weather window is installed generally very narrow, thereby will be seriously restricted the formulation of marine mount scheme, so that affect installation period.Have, barge is ship type buoyancy aid again, and transverse stability is poor conventionally, so the floating holder ability of chunk is very limited.
Summary of the invention
For the problems referred to above, the object of this invention is to provide that a kind of to have good lateral stability, weather window relatively spacious, and self propelled barge and the operational method thereof for the floating holder of jacket chunk that are conducive to save jacket structure steel using amount.
For achieving the above object, the present invention is by the following technical solutions: a kind of self propelled barge for the floating holder of jacket chunk, it is characterized in that, it comprises the hull that two parallel interval arrange, described in two, between hull, by two crossbeams that are positioned at bow, connect, in hull top described in two, one slideway of arranging along described ship length direction and a plurality of along the spaced block fixing device of described slideway is set respectively, one end that described in two, slideway is positioned at bow is respectively arranged with a pulling force jack, be positioned at stern two described in hull top the bindiny mechanism of at least one group is set; Described in every group, bindiny mechanism comprises a pair of driven wheel, a connecting cross beam, a guide rail and a pair of latch chamber; Described in two latch chamber be oppositely arranged on two described on hull, described connecting cross beam bottom is slidably supported on described in a side on hull along the direction perpendicular to described slideway by described guide rail, and run through and be positioned at described latch chamber and the slideway on hull described in homonymy, the two ends of described connecting cross beam are respectively arranged with a pin-and-hole, described in two, on latch chamber, be provided with the latch coordinating with pin-and-hole on described connecting cross beam, the both sides of described connecting cross beam are respectively arranged with tooth bar and mesh with driven wheel described in two, and described in two, driven wheel is arranged on a side hull at described guide rail place.
Described block fixing device is a pair of steel plate that is arranged on described slideway both sides, and steel plate bottom welding, in hull top, carries out temporary fixed in the mode of welding between steel plate and jacket chunk.
The anti-collision protection pad of one neoprene material is set respectively at hull afterbody described in two.
Also comprise that a bow deck house and two across hull described in two is positioned at the chamber, ship tween deck on described hull; On hull described in two, be also respectively arranged with a bow windlass, a stern windlass and a mooring column, described mooring column is arranged at stern; Described in each, hull bottom also arranges respectively four propelling units, bow two described propelling units that distribute side by side wherein, stern two the described propelling units that distribute side by side.
A kind of operational method of the self propelled barge for the floating holder of jacket chunk, the method comprises the following steps: 1) described self propelled barge is stopped fixing at harbour, and the two ends that make described connecting cross beam are fixed on described in two in the described latch chamber on hull by latch, adopt described pulling force jack that jacket chunk is slowly pulled to the assigned address on described hull slideway by harbour slideway, by described block fixing device, jacket chunk is fixed, then driven described self propelled barge to undock; 2) drive described self propelled barge to drive to marine site, jacket place, and be parked in jacket the place ahead; 3) from latch is extracted at described connecting cross beam two ends, controlling described driven wheel rotates, make with the described connecting cross beam of described driven wheel engagement along described guide rail side shifting outside self propelled barge, until described connecting cross beam shifts out the space between hull described in two completely, then handle described self propelled barge and slowly retreat, until contained jacket chunk arrive jacket directly over; 4) controlling described driven wheel rotates backward, make described connecting cross beam to described self propelled barge medial movement until its end extend into the described latch chamber on hull described in offside, insert the latch of latch chamber described in two, handle described self propelled barge dive jacket chunk is docked with jacket; After dive is completely separated with described self propelled barge to jacket chunk, again controlling described driven wheel rotates, make described connecting cross beam along described guide rail outside described self propelled barge side shifting until shift out the space between hull described in two completely, drive described self propelled barge to overtake, leave jacket; 5) adjust described self propelled barge floating, control described driven wheel and rotate backward, make described connecting cross beam to described self propelled barge medial movement until its end extend into the latch chamber of hull described in offside, insert two described in latch, sail out of marine site, jacket place.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention has adopted twin hull structure, improved the horizontal stability of barge, effectively promoted the floating holder of the chunk weight of barge, the beam that simultaneously also can single hull, the reduction of the beam can reduce the stand under load area of hull, and the weather window that chunk is installed expands to some extent.2, the present invention has adopted catamaran hull to float holder method, jacket structure no longer needs to design into headchute mouth, steel using amount is effectively controlled, upper chunk span can greatly reduce simultaneously, make chunk structural strength be more prone to satisfied, layout is more compact, and overall weight also can obviously reduce, the proposition of this barge concept, will produce material impact to jacket platform structure design and mounting means.3, the present invention has adopted and has controlled that stern easily can be opened, closed bindiny mechanism, under chunk, in water shipment, towage transportation and chunk and jacket docking operation, can make whole hull be closed frame structure, be conducive to various load in effective transmission of hull interior, ensure the structural safety of hull in operation process.The present invention can be widely used in the installation process of marine jacket chunk.
