Abstract
The invention discloses an efficient rapid emergency maintenance ship for a submarine pipeline, which is used for the maintenance of the submarine pipeline. A ship body, a lifting pile, a ventilating pile, a lifting drive device, a maintenance working cabin, a propeller drive system and a life building form the efficient rapid emergency maintenance ship for the submarine pipeline. The efficient rapid emergency maintenance ship for the submarine pipeline has the main installing mode that the lifting drive device, the propeller drive system and the life building are arranged on the ship body. During the maintenance of the submarine pipeline, the ventilating pile is placed through a drive gear of the lifting drive device to drive the maintenance working cabin to enter underwater until the butt position with the submarine pipeline is completed and then the pipeline maintenance operation is carried out. The propulsion function of the efficient rapid emergency maintenance ship for the submarine pipeline and the liftable technology of the maintenance working cabin ensure that the submarine pipeline is rapidly positioned without using high-cost ships, such as the tug, a floating crane, an auxiliary ship and the like, thus the maintenance period is effectively shortened, the pollution to the marine environment due to crude oil leakage is reduced, the safety production of a sea oil and gas field is ensured and the important economic loss is avoided.
Description
Technical field
What the present invention relates to is the sharp work ship that is used for the submerged pipeline repairing, belongs to mechanical field.
Background technology
Submerged pipeline is the important component part in marine oil gas field, is called as marine economic main artery, more than 60 of the submerged pipeline that China has built up in the coastal waters, and total length surpasses 3000 kilometers, spreads all over waters such as the Bohai Sea, the South Sea and the East Sea.But the thing followed is, environmental pollution, the explosion accident that cause because of sea-bottom oil-gas pipeline breaks at the Bohai Sea, the South Sea are on the increase in recent years, and this has not only cut off marine economic lifeline, need be up to several ten million yuan of rehabilitation expenses, and seriously have influence on local social stability.
The special report first on March 12nd, 2008 " Chinese marine oil newspaper ", it is to be enough to present submerged pipeline present situation is produced worry, write in the literary composition: " 9: 10 on the 6th November in 2007; in Zhanjiang Branch of China National Offshore Oil's east terminal Central Control Room; ... the disembarkation marineline pressure that shows on the computer screen ... 2 second downstream pressure dropped sharply to 0.9 MPa; ... see more than the 50 meter high flame of the enterprising ejaculation in sea in dead ahead, gas clips the constantly blast of water wave ... the gas dragon is died, the inside and outside a slice shock of Hainan Island ... local media is estimated like this: east 1-1 lands the fracture of pipeline, not only affect domestic chemical fertilizer, methyl alcohol market and Hainan people's life, and caused influence in the world ... the governor assistant of Hainan Province Li Guoliang ... for belligerent each side enables to depart in style: ... put one's ass on the line, wholeheartedly, guarantee that pipeline repairs completion early.Repair early? it is easier said than done ... there is not the crane barge ship that to mobilize near the most difficult is.Can only reach the wheel crane that land is used and carry out lifting operation on the auxiliary vessel; on December 30th, 2007 at about 11 pm; the chemical extra large oil in middle sea is built 600,000 tons of methanol devices of flood and is driven successfully ... we are successful in each repairing; can be at every turn we are very extremely awkward, a slight extra large pipe allows these extra large oily engineering technology elite feel exhausted.”
Can find out that from above-mentioned situation China's marine oil presses for a kind of actv. submerged pipeline repairing device that breaks, propose efficient submerged pipeline emergency first-aid repair ship fast for this reason.
The present invention is just for addressing the above problem design-calculated, purpose is to shorten maintenance cycle, reduce the pollution of crude oil leakage to marine environment, for the submerged pipeline repairing provides a kind of workboat effectively and rapidly, the realization submerged pipeline is repaired fast, heavy economic losses is avoided in the safety in production of guarantee offshore oil and gas field.
Summary of the invention
The technical problem to be solved in the present invention provides a workboat rapidly and efficiently that is used for the submerged pipeline repairing, certainly the boat function of this ship and workover module liftable technology, can realize that submerged pipeline locatees fast, need not employ expensive workboat tools such as tugboat, crane barge, support boat, the objective of the invention is provides a safe and reliable sharp work ship for the submerged pipeline repairing.
For addressing the above problem, the present invention is achieved in that the present invention mainly comprises hull, lifting pole, ventilation stake, lifting drive, workover module, propeller driving system and life building.One of its feature is that lifting drive, propeller driving system and life building all are installed on the hull.Two of its feature is that the quantity of lifting pole has 3 at least.Three of its feature is that 1 toothed rack is housed on the lifting pole at least, and tooth bar is meshed with the driven wheel of lifting drive.Four of its feature is in the ventilation stake 1 toothed rack to be housed at least, and tooth bar is meshed with the driven wheel of lifting drive.Five of its feature is that cowling is equipped with in the upper end of ventilation stake, and lower end and workover module connect.
This efficient working process of submerged pipeline emergency first-aid repair ship fast is: the first step is in place from navigating, when the submerged pipeline in a certain marine site breaks, pass through propeller driving system, efficient submerged pipeline emergency first-aid repair ship fast utilizes global position system to adjust the hull job position from the damaged place of the submerged pipeline that navigates.Second step was to promote hull, at first was to transfer lifting pole by the driven wheel of lifting drive, until lifting pole being inserted the seabed certain depth, then hull was promoted to certain altitude on the sea.The 3rd step was to transfer workover module, at first transferred the stake of ventilating by the driven wheel of lifting drive, and then drove workover module and enter under water, docked the location until finishing with submerged pipeline, carried out maintenance activity then.The 4th step was to promote workover module, and after the submerged pipeline maintenance was finished, the driven wheel lifting ventilation stake by lifting drive drove workover module and regains in the hull.The 5th step was to knock off to make a return voyage, and at first hull was reduced to the sea by the driven wheel of lifting drive, then lifting pole was extracted and be retracted to the hull lower end from the seabed, started propeller driving system at last, and efficient submerged pipeline emergency first-aid repair ship is fast maked a return voyage.
The present invention can solve long, the costly difficult problem of present submerged pipeline maintenance time, need not employ expensive workboat tools such as tugboat, crane barge, support boat, and it is simple and reliable for structure that whole boat equipment has, advantage convenient to operation.Workover module liftable technology of the present invention can realize effectively that submerged pipeline locatees fast, has very high application value.
