Abstract
The utility model discloses a novel floating drum applied on a floating production, storage and offloading unit. The novel floating drum comprises a standpipe A and a standpipe B, on which a sealing and isolating valve A and a sealing and isolating valve B are mounted respectively. A tee joint A and a tee joint B are disposed below the sealing and isolating valve A and the sealing and isolating valve B, respectively, and are connected via a connecting pipe. A control valve is disposed at the central portion of the connecting pipe. In case of emergency, after the floating drum which is ingeniously designed is disengaged and falls into water, the control valve at he central portion of the short connecting pipe can be automatically switch on, and then sea water or production water between two production platforms A and B can be used to flush submarine pipes so as to replace crude oil in the pipes, thereby preventing solidification of the crude oil in the submarine pipes and avoiding blockage of the submarine pipes.
Description
Technical field
The utility model relates to Floating Production and stores the emptying equipment field, and more particularly, it relates to a kind of novel floating drum that Floating Production stores the flushable sea of having of emptying equipment pipe function that can be used for.
Background technology
Floating Production stores emptying equipment and is called FPSO (Floating Production Storage&Offloading) again.It integrates production, stores outer defeated reach life, supply of power.Floating Production stores the component part of emptying equipment as the marine oil and gas development system, and generally form one with extracting device of oil under water with shuttle tanker and overlap complete production system, be the high-tech product in the present ocean engineering boats and ships.
Floating Production stores and to be connected with the sea pipe that stream send oil gas between emptying equipment and the offshore production platform, hang among the extra large Guan Zaishui one or several floating drums in.When meeting inclement weather, Floating Production stores the floating drum of emptying equipment and may free automatically, and after floating drum is freed, seal valve SELF CL will be detained the part transported substance in the pipe of sea, and will be long like the defeated time of Hai Guanting, very easily cause the sea pipe to condense.If in case coagulate pipe, so, the process of cleaning sea pipe will become very complicated, can cause long-time stopping production when serious.As shown in Figure 1, present existing FPSO floating drum, it mainly comprises standpipe A11, standpipe B12, seal valve A31, seal valve B32; Floating drum 10 is in case free automatically; Seal valve A31 and seal valve B32 close, and crude oil will be trapped in sea pipe A71 and the sea pipe B72, pollute because of can not crude oil directly being entered the seabed; Therefore, will face the dangerous situation that to wash the sea pipe.How to solve above-mentioned technical deficiency, become the technical barrier that remains to be captured.
The utility model content
The utility model technical matters to be solved provides the novel floating drum that uses on a kind of design Floating Production storage cleverly emptying equipment, and this novel floating drum is after chance emergency situation emergency release, and available seawater or production water wash the sea and manages, prevents the extra large pipe with fixed attention of managing.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Floating Production stores the novel floating drum that uses on the emptying equipment; It comprises standpipe A and standpipe B; Be separately installed with seal valve A and seal valve B on standpipe A and the standpipe B; Below said seal valve A and seal valve B, be separately installed with threeway A and threeway B, connect with connection pipe between threeway A and the threeway B, be provided with control cock in the middle of the connection pipe.
The utlity model has following beneficial effect:
The utility model has been owing to adopted said structure, through inner at floating drum, sea pipe bypass line is installed below freeing the place, floating drum is in case of emergency freed after; Can effectively two sea pipes directly be communicated with through this bypass pipe, therefore, when work; Can pour into seawater from the sea pipe of any end of two production platforms or produce flushable object such as water; The sea pipe is washed, and the flushing thing is discharged from the sea pipe of the production platform of the other end, can prevent that crude oil condenses in the pipe of sea.So when meeting emergency situation, the utility model can conveniently clean the sea pipe, prevent that the sea pipe from coagulating pipe that simultaneously, the utility model design is ingenious, low cost of manufacture.
After the detailed description of the embodiment that combines advantages the utility model, it is clearer that characteristics of the utility model and advantage will become.
Description of drawings
Fig. 1 is the structural representation of existing floating drum.
Fig. 2 is the structural representation of the embodiment of the utility model.
Wherein:
10. floating drum, 11. standpipe A, 12. standpipe B, 21. pneumatic control valve A, 22. pneumatic control valve B; 31. seal valve A, 32. seal valve B, 41. threeway A, 42. threeway B, 5. connection pipes; 6. control cock, 71. sea pipe A, 72. sea pipe B, 81. production platform A, 82. production platform B.
The specific embodiment
With an embodiment the utility model is done further detailed explanation below, but should explain that the protection domain of the utility model is not limited only to this.
Consult Fig. 1, Floating Production stores the novel floating drum 10 that uses on the emptying equipment, and it comprises standpipe A11, standpipe B12, seal valve A31, seal valve B32, threeway A41, threeway B42, short tube 5 and control cock 6.Be separately installed with seal valve A31 and seal valve B32 on standpipe A11 and the standpipe B12; Below said seal valve A31 and seal valve B32, be separately installed with threeway A41 and threeway B42; Connect with connection pipe 5 between threeway A41 and the threeway B42, be provided with control cock 6 in the middle of the connection pipe 5.
In the time of ordinary production, pneumatic control valve A21, pneumatic control valve B22, seal valve A31, seal valve B32 all are in opening, and control cock 6 is in closure state, and two sea pipes are not communicated with mutually, separately to the FPSO conveying crude oil.When running into emergency situation; When signal was freed in triggering, pneumatic control valve A21 and pneumatic control valve B22 can close through connecting rod drive seal valve A31 and seal valve B32 from SELF CL then; Drive control cock 6 simultaneously and open, floating drum can drop into the sea automatically then.This moment two production platforms 81 with 82 can manage 71 through the sea, standpipe 11, short tube 5, control cock 6, standpipe 12, sea manage 72 and be interconnected.If can not before crude oil solidifies, resume production; Then can pour into seawater or produce flushable object such as water from the sea pipe of any end of production platform A 81 or production platform B 82; The sea pipe is washed, and the flushing thing is got rid of from the production platform of the other end, can prevent that the sea pipe from condensing.
Though described the embodiment of the utility model in conjunction with accompanying drawing; But those skilled in the art can make various distortion or modification within the scope of the appended claims; As long as be no more than the described protection domain of the claim of the utility model, all should be within the protection domain of the utility model.
