Description
Technical field
The utility model belongs to offshore and gas development field, particularly relate to a kind of for offshore oil and gas field isolated under water
Flexible storage device.
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) it is stored in
In Fuel Tanking Unit, regular shuttle tanker transports, and this Fuel Tanking Unit can be a fixing part of production platform, also
It can be a single structure.If the yield of an offshore oilfield is big not, just lay expensive pipeline under the ocean
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 on
In platform topsides chunk；2) as a part for floating structure on the water surface；3) as platform understructure below Water Plane
A part, or as a single facility.The Fuel Tanking Unit being positioned at below Water Plane needs by piping raw with platform
Product chunk is connected and fetches the handling operation carrying out crude oil.Three positions respectively have excellent, shortcoming in actual applications.1) at waterline
Time more than face: Fuel Tanking Unit, usually used as a standing part of upper strata chunk, is placed directly within technical module and accommodation module
Under.Advantage is that the ocean current power not produced by wave and tide is affected.But, huge Fuel Tanking Unit is placed in technique
Serious potential safety hazard can be constituted under module and accommodation module.Additionally, the most this layout increases to table top
Add huge weight, be allowed in crude oil cargo handling process, produce the biggest weight change, thus greatly have impact on platform
Motor imagination feature.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) exist
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 needs to rely on an expensive mooring system or alignment system
Keep marine positioning, therefore can be more much higher than conventional fixed platform cost.To this end, floating structure is only at deep water
Recover the oil or shallow water recover the oil needed for the tangible cost of oil pipeline the highest time just can use.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, by
The environmental forces that wind produces 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 the dynamic characteristics of platform and motor imagination.But underwater oil storing device can face many
Challenge.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
It is " wet type oil storage method ", will be stored in together with seawater in same oil storage tank by oil.Owing to density is different, crude oil or liquid
State 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 naturally
Layer.The crude oil processed when loading operation is injected in oil storage tank, and the seawater 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, seawater is injected into equivalent in tank
Crude oil 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
About the 15% of end weight is sat for maximum.Another advantage is, due to the storage tank pressure that it is internal in whole service life
Remain hydrostatic pressure balance with outside seawater, 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, crude oil
Can produce a mixed layer with the contact surface of seawater, this mixed layer such as discharges will be to environment.Second is
Heat-insulating problem, 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 very
Crude oil is taked Insulation by difficulty.3rd, the method cannot store water-soluble liquid, such as methyl alcohol.Just because of these
Shortcoming, particularly problem of environmental pollution, although insider has made huge effort, but wet type oil storage method either exists
The case obtaining actual application in fixed platform or floating platform is few.
The method of the second oil storage is " dry type oil storage method ".Use this method profit directly to contact, the most no matter processed
Crude oil or liquid hydrocarbon can be stored in underwater storage tank.Additionally, crude oil can be incubated well.No
Crossing, the method faces two serious challenge.First, a large amount of buoyancy can be produced during emptying.Secondly, need to use lazy
Property gas, and inert gas leakage can to environment.Inject inert gas into closing oil storage tank oil reservoir superjacent air space
The gas stoping crude oil to volatilize spills storage tank and causes air pollution.But, the generation of inert gas in application, injection are also
Form the process such as sealant, exhaust all to leak and become pollution sources.In above-mentioned multiple serious challenge, disappear
Produce during offsetting emptying except the solution of a large amount of buoyancy problem typically uses the gravity foundation of a cement manufacture
Buoyancy.Another method solving excess buoyancy is additionally to build several ballast tanks on oil storage tank limit, past during emptying
In ballast tank, the buoyancy of overall generation is offset in water filling.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, in only case
In example, the overwhelming majority is applied to cement gravity foundation platform.
On October 23rd, 2012, american documentation literature US8292546B2 disclosed the concrete of a kind of dry type oil storage method
Scheme, proposes a wet tank and joins a corresponding seawater ballast tank, and both are symmetrical, above two pot liquids all
It is injected with inert gas intercommunication.During oil loading and unloading, this Fuel Tanking Unit constantly carries out profit by two set oil/water pumping systems
Weight displacement carrys out the uniformity of holding means gross mass, and device center of gravity may only move up and down along an axis simultaneously.This is
The great advantage of system is that the gross weight of device is always consistent during loading and unloading oils.But, this device exists three
Problem.First, the overall actual reserves of device is the lowest because the volume of more than the 50% of system need to be used for storing seawater and
Inert 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, to platform safety
Cause a hidden trouble.Second, due to the existence of seawater ballast tank, add the overall weight of device.3rd, whole oil storage fills
The effective operation put needs to rely on can carried out the crude oil in oil storage tank and ballast tank or seawater respectively with taking out with row
Complicated sundstrand pump system, there is the potential safety hazard run reliably and with long-term in this system.
