The present invention relates to a floating pump casing for floating production storage.

Floating Production Storage and Offloading (FPSO) is a special ship equipped with various facilities capable of refining and storing crude oil or marine gas mined from subsea oil fields and loading and unloading such as shuttle tanker or LNG carrier . On the side of the floating production storage and unloading facility, a pump caisson can be installed which can raise seawater. The pump caisson must be positioned lower than the bottom so that seawater can be pulled up below the bottom. However, pump casings that are not used until the float production storage and unloading facilities start from the dry yard and arrive at the operating site, are placed on the side of the floating production storage and unloading facility so that the bottom is located at the same or higher position than the bottom It shall be installed temporarily by welding or the like so as not to interfere with ship operation. Accordingly, after the floating production storage and unloading facility arrives at the operating site, the temporary welding portion of the pump casing must be dismantled, the height of the pump casing must be lowered, and the pump casing must be permanently welded to the hull. Particularly, when the weight of the pump caisson is larger than the capacity of the main crane to be operated at the operating site, the pump caisson must be dividedly mounted, so that the assembling work of the pump caisson may be added.

The pump casing according to the present invention may be installed in floating production storage and offloading (FPSO). That is, the pump caisson according to the present invention can be applied to a special ship that performs a predetermined mission while moving from a dry yard to an operating site like a floating production storage / unloading facility.

FIG. 1 is a view showing a pump caisson according to an embodiment of the present invention, and FIG. 2 is a view showing a pump caisson according to an embodiment of the present invention in a state where a seawater pipe is lowered.

1 and 2, a pump caisson 10 according to an embodiment of the present invention includes a seawater pump 100, a seawater pipe 200, a fixing bracket 300, a guide bracket 400, and a transfer unit 500 ).

The seawater pump 100 may be installed in the seawater pipe 200.

The seawater pump 100 may be disposed in the inner space of the seawater pipe 200.

The seawater pump 100 may provide fluid pressure to allow seawater to be sucked through the lower end of the seawater pipe 200 and flow to the upper end.

The seawater pipe 200 may provide a seawater passage.

The seawater pipe 200 may have a hollow cylindrical shape with an open top and a bottom.

The seawater pipe 200 can be coupled to the floating storage device 20 via the fixing bracket 300 so as to be movable up and down.

The seawater pipe 200 may have an integral structure. That is, the seawater pipe 200 can be formed as a one-piece structure in which the upper part and the lower part are not separated and no joint exists between the upper part and the lower part. As a result, it is possible to completely prevent the leakage of seawater during the movement of the seawater through the seawater pipe 200, thereby minimizing the capacity of the seawater pump 100.

A stopper 210 may protrude from the upper outer peripheral surface of the sea water pipe 200.

The stopper 210 can limit the height at which the seawater pipe 200 can descend to the maximum.

The stopper 210 is in close contact with the upper surface of the fixing bracket 300 when the sea water pipe 200 descends by a predetermined distance by the conveyance unit 500 so that the height at which the sea water pipe 200 can be lowered to the maximum can be limited have.

The lower end of the seawater pipe 200 may be located below the bottom of the floating production storage and unloading facility 20 when the stopper 210 is in close contact with the upper surface of the stationary bracket 300. As a result, after the floating production storage / unloading facility 20 moves to the operating site, the sea water pipe 200 is lowered by the transfer unit 500 until the stopper 210 is brought into close contact with the upper surface of the fixed bracket 300 The descent height of the seawater pipe 200 can be easily controlled by the stopper 210. [

The stopper 210 may prevent the seawater pipe 200 from being excessively lowered or further separated from the first through hole 310 of the fixing bracket 300 when a failure occurs in the transfer unit 500.

The stationary bracket 300 may be coupled to one side of the floating production storage and unloading facility 20. [

The fixing bracket 300 may have a first through hole 310 through which the seawater pipe 200 is inserted. As a result, the seawater pipe 200 can be supported by the fixing bracket 300 by being inserted into the first through-hole 310.

The guide bracket 400 may be coupled to one side of the floating production storage / unloading facility 20 like the fixing bracket 300.

The guide bracket 400 may be disposed under the stationary bracket 300.

The guide bracket 400 may be formed with a second through hole 410 through which the seawater pipe 200 is inserted in a vertical direction. As a result, the guide bracket 400 can support the seawater pipe 200 in cooperation with the fixing bracket 300 and guide the seawater pipe 200 moving up and down.

The guide bracket 400 may be provided in a plurality of ways to stably support and guide the sea water pipe 200 according to the length of the sea water pipe 200.

The wear-resistant member 420 may be formed on the inner circumferential surface of the guide bracket 400, specifically, the second through-hole 410.

The wear-resistant member 420 may contact the seawater pipe 200 moving up and down through the second through-hole 410. As a result, the wear-resistant member 420 can prevent the guide bracket 400 from being worn by the upward and downward movement of the sea water pipe 200.

The transfer unit 500 can transfer the seawater pipe 200 up and down.

The transfer part 500 may include a female screw part 510 and a male screw part 520.
