Description
Technical field
The present invention relates to a kind of Fuel Tanking Unit and installation method thereof, particularly about a kind of water surface Fuel Tanking Unit and installation method thereof with mooring function.
Background technology
Along with offshore oil field enters stable yields and decline stage successively, exploitation deep water and marginal oil field are imperative.The realistic problem that present China faces is: deep water oil field offshore is far away, and relies on without ripe sea-bottom pipe-network, and the oil field operation is stronger for the dependence of FPSO; And some isolated marginal oil field scales are less, and its simple and easy production platform does not possess again larger oil storage function, and output crude oil relies on pipe defeated disembarkation far away in sea not have economy, therefore is necessary to set up marine oil storage facility.Marine oil storage solution when as seen developing the deep water marginal oil field will have important engineering practical value for the exploitation of small deep water marginal oil field.
That present marine oil storage mainly is divided into is waterborne, the water surface and three kinds of modes under water.1) oil storage waterborne, namely petrol storage tank places on the fixed platform, and such as chengbei oilfield, this mode oil reserve is little, and construction costs is high, is only applicable to the less oil field of shallow water and output.2) oil storage under water, petrol storage tank are arranged at seabed or under water, such as the Gullfahs C concrete platform in the North Sea, because capacity is large, isolated with the burning things which may cause a fire disaster thunder and lightning, safety is better, and avoided the impact of wind and surface wave, the oil field still can produce continuously under the severe sea condition.Its weak point is that to the having relatively high expectations of ocean bottom soil characteristic and planeness when rock or big rise and fall were arranged at the sea bed bottom, structural safety was difficult to meet the demands, and the structural materials consumption is large in addition, and not recyclable, is only applicable to the larger oil field of reserves; Underwater repair is safeguarded and is also had great difficulty.3) water surface oil storage maneuverability is recyclable, uses also extensively, but faces three difficulties: the one, and crude oil loading and unloading process displacement changes greatly, need to adjust at any time ballast, and also there is hidden danger in stability safety in addition; The 2nd, if adopt large waterplane buoyancy aid, then be subjected to easily the impact of environmental load, if adopt dark drinking water buoyancy aid, for overcoming the pressure reduction of inside and outside, buoyancy aid need be done a large amount of reinforcement structures, material usage obviously promotes again; The 3rd, oil storage chamber contacts with air, and fire prevention is large with anti-riot difficulty; Therefore water surface oil storage need to effectively solve the difficulties of above three aspects.
