Description
Technical field
This utility model belongs to offshore and gas development field, particularly relates to a kind of deep water floating oil gas platform using flexible storage device under water.
Background technology
Two kinds of methods are had to carry out subsequent treatment: 1 after offshore oilfield output crude oil) export with submarine pipeline；2) being stored in regular shuttle tanker in Fuel Tanking Unit to transport, this Fuel Tanking Unit can be a fixing ingredient of production platform, it is also possible to be a single structure.If the yield of an offshore oilfield is big not, lays expensive pipeline under the ocean and just lose more than gain, in this case to exploit and just can only use certain low cost but safe and reliable Fuel Tanking Unit.
Fuel Tanking Unit is more particularly arranged at the most essential.Optional position only has three: 1) more than Water Plane and be fixed in platform topsides chunk；2) as a part for floating structure on the water surface；3) as a part for platform understructure below Water Plane, or as a single facility.It is positioned at the Fuel Tanking Unit of below Water Plane to need to produce chunk with platform by piping and be connected to fetch and carry out the handling operation of crude oil.Three positions respectively have excellent, shortcoming in actual applications.1) time more than Water Plane: Fuel Tanking Unit, usually used as a standing part of upper strata chunk, is placed directly within technical module and accommodation module.Advantage is that the ocean current power not produced by wave and tide is affected.But, huge Fuel Tanking Unit is placed under technical module and accommodation module and can constitute serious potential safety hazard.Additionally, the most this layout adds huge weight to table top, it is allowed in crude oil cargo handling process, produce the biggest weight change, thus greatly have impact on the motion response feature of platform.Therefore, this scheme is applied on the fixed platform being positioned at Very Shallow Water territory at present the most on a small quantity.2) at the water surface: advantage is can be readily added platform to be similar to the oil storage volume of ship shape FPSO floating structure.But shortcoming is, the environmental forces that floating structure is easily produced by stormy waves is affected, thus need to rely on an expensive mooring system or alignment system to keep marine positioning, therefore can be more much higher than conventional fixed platform cost.To this end, the floating structure only tangible cost of oil pipeline needed for deepwater production or shallow water recover the oil just can be used time the highest.3) below Water Plane: no matter for fixed platform or floating platform, this is all optimum position, as long as because the underwater degree of depth of oil storage tank is enough deep, wind the environmental forces produced just is wholly absent, wave the environmental forces produced also can weaken significantly.Additionally, the center of gravity of platform also can decline, the most beneficially dynamic trait of platform and motion response.But underwater oil storing device can face many challenges.Stern challenge produces when being how to process loading and unloading oils huge buoyancy and corresponding platform weight change.
Fittings storage device generally has two kinds of methods to store the crude oil processed or other liquid hydrocarbons.The first is " wet type oil storage method ", will be stored in together with sea water in same oil storage tank by oil.Owing to density is different, crude oil or liquid hydrocarbon can float over the top of oil storage tank, although and profit can directly contact but both meetings are divided into upper and lower two-layer naturally.The crude oil processed when loading operation is injected in oil storage tank, and the sea water of simultaneous equal can be discharged out oil storage tank, so that the volume of oil storage pot liquid keeps constant.The process contrast of emptying, sea water is injected into the crude oil of equivalent in tank and is extruded outside tank.When the great advantage of this oil storage method is loading and unloading oils, weight at the bottom of the seat of storage tank varies less, and variable quantity is only maximum and sits about the 15% of end weight.Another advantage is, owing to the storage tank pressure that it is internal in whole service life remains hydrostatic pressure balance with outside sea water, therefore need not it is designed to pressure vessel.But, the method also has three big shortcomings.First is exactly the worry of environmental pollution.Owing to storage tank the most constantly rocks, the contact surface of crude oil and sea water can produce a mixed layer, and this mixed layer such as discharges will be to environment.Second is heat-insulating problem, and oil keeps liquid to need heating and thermal insulation, and the water come in outside is cold, and therefore the large-area contact of profit is difficult to crude oil is taked Insulation.3rd, the method cannot store water-soluble liquid, such as methanol.Just because of these shortcomings, particularly problem of environmental pollution, although insider has made huge effort, but the case that wet type oil storage method either obtains actual application in fixed platform or floating platform is few.
The method of the second oil storage is " dry type oil storage method ".Using this method profit directly to contact, the crude oil or the liquid hydrocarbon that the most no matter processed can be stored in underwater storage tank.Additionally, crude oil can be incubated well.But, the method faces two serious challenge.First, a large amount of buoyancy can be produced during emptying.Secondly, need to use noble gas, and noble gas leakage can be to environment.Inject inert gas into closing oil storage tank oil reservoir superjacent air space to spill storage tank to the gas stoping crude oil to volatilize and cause air pollution.But, the generation of noble gas in application, inject and form the process such as sealant, aerofluxus and all may leak and become polluter.In above-mentioned multiple serious challenge, eliminate the solution of a large amount of buoyancy problem and typically use the gravity foundation of a cement manufacture to the buoyancy produced during offsetting emptying.Another method solving excess buoyancy is additionally to build several ballast tanks on oil storage tank limit, offsets the buoyancy of overall generation during emptying toward water filling in ballast tank.No matter which kind of method all can make whole storage device itself the heaviest.Above-mentioned variety of problems, the case making dry type oil storage method obtain practice in offshore oil production industry is little, and in only case, the overwhelming majority is applied to cement gravity foundation platform.
On October 23rd, 2012, american documentation literature US8292546B2 disclosed the concrete scheme of a kind of dry type oil storage method, proposes a wet tank and joins a corresponding sea water ballast tank, and both are symmetrical, are all injected with noble gas intercommunication above two pot liquids.During oil loading and unloading this Fuel Tanking Unit by two set oil/water pumping systems constantly carry out profit weight displacement come holding means gross mass concordance, device center of gravity may only move up and down along an axis simultaneously.The great advantage of this system is that the gross weight of device is always consistent during loading and unloading oils.But, there are three problems in this device.First, the actual reserves of device entirety is the lowest, because the volume of more than the 50% of system need to be used for storing sea water and noble gas.Therefore, the excessive buoyancy more than 50% can be produced during dry type oil storage method emptying, and wet type oil storage method only produces the buoyancy of about 15%.In order to solve the problem of above-mentioned excess buoyancy, generally use heavy cement structures rather than use the Steel material that offshore platform is conventional.Cement structures is directly sat at the end, easily produces undermining and empties phenomenon, causes a hidden trouble to platform safety.Second, due to the existence of sea water ballast tank, add the overall weight of device.3rd, the effective operation of whole Fuel Tanking Unit needs to rely on the complicated sundstrand pump system that can carry out the crude oil in oil storage tank and ballast tank or sea water respectively with taking out with row, and this system exists the potential safety hazard run reliably and with long-term.
