Background
In recent years, the number of deep water sea pipes is continuously increased, and accidents of sea pipe damage caused by long-term design and construction of the sea pipes, pipeline corrosion, trawl fishing vessel dragging and the like are more frequent. Once the sea pipe is damaged, the sea environment and the oil and gas field production are threatened greatly. When the submarine sea pipe is damaged, the common maintenance mode is to recycle the sea pipe to the water surface for maintenance and then to lower the sea pipe to the seabed. The sea pipe recovery process requires special tools to complete recovery operation.
At present, an experimental sea Pipe Recovery Tool (PRT) exists in China, but the tool is inserted into a steel pipe to finish sea pipe recovery operation, and cannot be used for recovery operation of sea pipes, cables and the like; meanwhile, due to size limitation, the PRT with one specification can only recover steel pipes with corresponding pipe diameter sizes, and cannot cope with the recovery condition of a plurality of sea pipes with different pipe diameters. No special tools for subsea sea pipe and cable recovery have been found, especially for deep water sea pipes above 300 meters.
The water depth of the pipeline of the Li Gulf-1 gas field which is put into production in China at present reaches 1500 meters, and the water depth of the 17-2 project of the tomb water which is being developed reaches 1700 meters. Once the pipeline of the deepwater oil-gas field leaks, serious marine environmental pollution and huge economic loss can be caused, and the research on deepwater sea pipe emergency maintenance equipment is not slow.
