Description
Technical field
The present invention relates to submerged pipeline emergency repairing device, belong to field of ocean engineering.
Background technology
Submarine pipeline has become the marine politics of China, economical " large artery trunks ", mainly includes oil pipeline, gas pipeline and defeated
Waterpipe etc..Surging with energy demand, the length of submarine oil-transportation Gas pipeline system and performance improve constantly.At present, I
The submarine pipeline of state's coastal waters offshore oil and gas field builds 60 a plurality of, and total length reaches more than 3000 kilometer, wherein, Pinghu oil and gas field in East China sea
To seafloor gas seepage and the pipeline under the ocean to Mount Dai island in Shanghai, length is more than 300 kilometers.However, due to Submarine Pipeline
Road local environment is extremely complex, the factor impact such as suffers from wave, ocean current, Trawl gear, casts anchor, the situation of Pipeline damage is repeatly
See not fresh, and be mostly sudden accident.In recent years, a lot of submarine pipelines were all once occurred in that at the Bohai Sea, the East Sea and the South Sea
Damage seepage accident, such as：
One submarine pipeline of 1.1996 years South Sea Huizhou Oilfields is broken by fishing boat trawlnet, causes oil field to stop production 37 days, marine
Maintenance cost reaches 35,000,000 yuan；
2.1998 years East Sea Pinghu oil field long distance gas transmission pipeline seepage, causes this oil field to postpone and goes into operation 3 months, economic damage
Lose close to 1.6 hundred million yuan；
One filling pipe of 3.1999 years Bohai Sea Caissons in JZ 9-3 Oil Fields damages, marine 7,000,000 yuan of cost of maintenance；
One, the Bo Xi oil field in Bohai Sea Gulf in 2000 sea-bottom natural gas conveyance conduit is drawn by marine anchor and is damaged seepage, marine dimension
Repair 10,000,000 yuan of investment；In 6 days November in 2007, extra large oil DF1-1 diapir submarine pipeline is dug disconnected by a dredger, spouts in sea
Project more than 50 meter of high flame, gas clips water wave and constantly explodes.Due to the domestic extra large pipe maintenance troop also not having specialty, own
Repair personnel assembles from constituent parts temporarily, Xin Renduo, lack of experience, break-in hardly possible, contact difficult coordination.Do not set
Standby, there is no a professional, or even shoulder the Labor Workers of sandbag all to can not find, repairing project team group leader can only be allowed to lead technical staff
Shoulder sand together up.Be most difficult to is nearby not have a crane barge ship that can mobilize, and the truck crane on land can be reached work
Lifting operation is carried out on journey ship, finally, to evening on December 30th, 2007, repair personnel overcomes all difficulties, completes DF1-1 diapir
The reparation of submarine pipeline." every time we are successful for repairing, can we are very extremely awkward every time." a slight extra large pipe allow these
Sea is oil engineering technology elite feel exhausted." DF1-1 diapir pipeline is not first impaired submarine pipeline.Although " satisfactory
Complete reparation task, can this time project manager of extra large pipe repair, long campaigns submarine pipeline repair sea oil work
The journey repair company Pan chief engineer east people are still weighed down with anxieties.Early in June nineteen ninety-five, the crude oil pipeline of XJ24-3 oil field
Just as seawater corrosion occurred leakage, have no ability at that time submarine pipeline is repaired, international specialty dimension have to be asked
Repair company.That repair one has shared 9 day time, spends 2,900,000 dollars of fund.And this pipeline has just just been fixed soon
Leak again in July then, spend more than 200 ten thousand dollars please foreign corporation be repaired again, therefore China's submarine pipeline
Rupture repairing device in the urgent need to a kind of effective submarine pipeline, be a urgent problem.
Content of the invention
It is an object of the invention to provide submerged pipeline emergency repairing device.
The problem to be solved in the present invention is the deficiency that existing submarine pipeline maintenance does not have good equipment.
For realizing the purpose of the present invention, the technical solution used in the present invention is：

Come in and go out.
Advantages of the present invention：The underwater operation maintenance lock Dual positioning of this equipment jack up submarine pipeline emergency repairing device
Technology, is capable of submarine pipeline and quickly positions, and is not required to employ the high cost workboat such as crane barge, support vessel tool, not only saves and apply
Work cost, and effectively shorten the activity duration.Workover module is directly driven using lifting pole and drops to seabed, is effectively simplified
Submarine pipeline maintenance activity program, assists under water without diver, develop normal pressure dry method underwater maintenance work chamber simultaneously so that
Welder remains to obtain the dry-type working environment of an atmospheric pressure as land it is not necessary to carry out adaptability under water under water
