Abstract
The invention discloses a kind of underwater oil sump tank and its application method, underwater oil sump tank includes closed babinet, the water filling port for the disengaging babinet that supplies water being arranged on the babinet and the oil inlet and oil outlet of discharge outlet and the fuel feeding disengaging babinet being arranged on the babinet；Under the babinet during water, by the water filling port to the box house water filling；The discharge outlet and oil inlet are located on the opposite sides face of the babinet, with the draining in oil inlet.The underwater oil sump tank of the present invention, it can be placed directly on sea bed, collect the irreducible oil of impaired submerged pipeline, it solves the problems, such as to lead to not due to crude oil condenses directly to suppress crude oil and be delivered on the oil-collecting boat oceangoing ship of sea, while can also evade the situation that the tedge temperature drop because caused by the depth of water is too deep causes crude oil frozen plug to receive oily hose.
Description
Technical field
The present invention relates to technical field of underwater operation more particularly to a kind of underwater oil-collectings for submerged pipeline leak source reparation
Case and its application method.
Background technology
In recent years, ocean engineering high speed development, with marine petroleum development, have every year up to a hundred kilometers of pipelines be laid to
On sea bed.According to extra large oily engineering statistics, 296 kilometers of laying submerged pipeline in 2014,627 kilometers of pipeline installation in 2013.Increasingly
More submerged pipelines will necessarily increase the risk of third party damage.
In addition, sea oil oil development progressively deep water is entered by shallow water, once the oil transportation sea pipe of depth of water higher depth goes out
Existing leak source, pipeline shutdown would become hard to directly collect to above water craft by way of suppressing after the irreducible oil condensation in extra large pipe
On.Even if crude oil does not condense, since the depth of water is too deep, also can there are crude oil in tedge transmission process because temperature drop coagulates
Gu block the problem of receiving oily hose.This just needs an oil collector it is former can to collect condensation as close possible to damaged sea pipe
Oil.
At present, it is general by the way of receiving oil bag and adding clump weight, irreducible oil is collected into receipts oil bag, but due to receiving oil
Bag capacity is small, need to frequently replace, while also easily leads to crude oil leakage, pollution of marine environment.Therefore, it is necessary to design one to place
In sea bed large capacity oil sump tank and be equipped with and be conveniently replaceable the interface of connection, to optimize the receipts oil operation of irreducible oil.

S1.2, by babinet 10 into the water, be arranged in close to submerged pipeline leak source 60 on smooth sea bed.
Specifically, on water surface oil-collecting boat oceangoing ship, hoisting rig is connected to the lifting lug on babinet 10, lifting babinet 10 to the side of a ship
Side is put into water under slow, babinet 10 is arranged in close to submerged pipeline leak source 60 on more smooth sea bed, loosens rigging, treats
It is settled 15 minutes, then confirms whether babinet 10 is placed steadily.If babinet 10 is placed steadily, suspension hook is unlocked, rigging is along babinet 10
The 8 side nature lowering of manhole passage；If babinet 10 is not steady, lifting again is placed.Wherein, babinet 10 is put by anti-settling pedestal 20
In on sea bed.
S1.3, the oily hose 30 of receipts is connected in the oil inlet 3 of babinet 10, receives oily hose 30 and be connected to oil inlet 3 and Submarine Pipeline
Between line leak source 60.
Discharge outlet 2 on S1.4, open babinet 10, open oil inlet 3 make oil inlet 3 be connected with oily hose 30 is received, seabed
The irreducible oil of pipeline enters babinet 10 by receiving oily hose 30 and oil inlet 3.Water in babinet 10 is expelled by crude oil, through draining
Mouth 2 discharges babinets 10；The drained rear closing discharge outlet 2 of water in babinet 10.
If irreducible oil state meets water surface transport condition, it can open and rise valve 41, and close oil inlet valve 31, it is remaining
Crude oil then can be delivered to water surface oil-collecting boat oceangoing ship through rising hose 40.
In step S1.4, suppressed by injecting hot water to submerged pipeline so that irreducible oil is discharged by leak source, so as to pass through
It receives oily hose 30 and oil inlet 3 enters babinet 10.
After the full oil of a babinet 10, when crude state is still unsatisfactory for water surface transport condition, then underwater oil sump tank is carried out more
Operation is changed, oily hose 30 will be received and be connected on second babinet 10, carries out receiving oil by second babinet 10.
Babinet 10 is recovered to after full oil or after irreducible oil is collected on water surface oil-collecting boat oceangoing ship.It is similary logical during recycling
The lifting lug that hoisting rig is connected on babinet 10 is crossed, is lifted by crane on babinet 10 to deck.
Underwater oil sump tank comprises the following steps in oil extraction operation：
S2.1, the water filling port 1 on open babinet 10 and oil outlet 4.
S2.2, hot water or steam are injected in babinet 10 by water filling port 1, to add to the crude oil collected in babinet 10
Temperature, crude oil discharge babinet 10 from oil outlet 4.Wherein, it is made to facilitate discharge in fluidised form crude oil heating by hot water or steam.
After oil extraction operation is completed, staff can be entered by the manhole passage 8 on babinet 10 inside babinet 10, to case
The work such as it is detected and cleans inside body 10.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made directly or indirectly is used in other relevant skills
Art field, is included within the scope of the present invention.
