Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The Floating Production storage unloading system single-point oil production platform 100 according to the embodiment of the present invention is specifically described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, according to the Floating Production of embodiment of the present invention storage unloading system single-point oil production platform 100 comprise deck 10, oil gas treating device 20, riser systems 30, for providing buoyancy aid 40 and the mooring system 50 of buoyancy.
Specifically, oil gas treating device 20 is located on deck 10, and oil gas treating device 20 is by plumbing system 30 and subsea wellhead, and namely underwater oil well is connected.Multiple buoyancy tanks 42 that buoyancy aid 40 can comprise column 41 and be fixedly connected with column, multiple column 41 circumferentially direction is spaced from each other layout, and two namely adjacent columns 41 directly have preset distance.
Multiple column 41 is hollow structure, and can provide buoyancy for whole platform, and have multiple oil storage space (depending on going out) in the internal structure of each column 41, oil storage space can arrange the mouth of going on a tour be positioned at above column 41, so that deposit crude oil.
Multiple columns 41 are positioned at the below on deck 10, and the upper end of multiple column is directly connected with the lower end on deck respectively, such as, for being fixedly connected with, with support deck 10.
It should be noted that, each buoyancy tank 42 is connected between two adjacent columns 41, and multiple buoyancy tank 42 is hollow structure, and have multiple oil storage space (depending on going out) than domestic in internal structure, the oil storage space on buoyancy tank 42 may be used for depositing crude oil equally.And, each buoyancy tank 42 is arranged all in the horizontal direction and the lower end on distance deck 10, the upper end of each buoyancy tank 42 has preset distance, the lower surface of multiple column 41 and multiple buoyancy tank 42 in same level, to become center to have hole at the substructure of buoyancy aid and the loop configuration of bottom in same level.This loop configuration makes whole buoyancy aid 40 more firm.Such as, this loop configuration can be welded by multiple column 41 and multiple buoyancy tank 42.
Be understandable that, Floating Production storage unloading system single-point oil production platform 100 according to the embodiment of the present invention forms primarily of deck 10, oil gas treating device 20, buoyancy aid 40 and mooring system 50, wherein, deck 10 is for installing top facility, and oil gas treating device 20 is located on deck 10 to process the crude oil from oil well extraction.Buoyancy aid 40 is formed primarily of multiple column 41 and multiple buoyancy tank 42, and the upper end of each column 41 is directly connected with the lower end on deck 10 respectively and can provides buoyancy and stability for deck 10.
Mooring system 50 is connected with in multiple column 41, to be fixed buoyancy aid 40 and whole platform, namely mooring system 50 can ensure the position of whole Floating Production storage unloading system single-point oil production platform 100, and one in multiple column 41 may be used for placing this mooring system 50.
Thus, according to the Floating Production storage unloading system single-point oil production platform 100 of the embodiment of the present invention, by the float structure that the multiple column 41 of employing and buoyancy tank 42 that traditional Chuan Xing floating production storage offloading (FPSO) are improved to the application combine, ensure that platform has good stability, reduce waterplane area simultaneously, platform heaving natural period was significantly reduced away from the Wave energy cycle, and many column 41 formula structures reduce wave-drift force suffered by platform and slow-drift motion displacement, system is made to be easy to design.
