Background
Pipeline transportation is the fourth transportation mode except for ships, railways and highways, and according to incomplete statistics, 70 kilometers exist in the United states, 23 kilometers exist in Russia, and only 9 kilometers exist in China. Meanwhile, the submarine oil and gas pipeline in gulf of Mexico is about 37000 kilometers, and China is about 3600 kilometers. The pipeline construction in China, particularly the submarine pipeline construction, is still in the starting stage due to the limitation of technology and market, and has huge market potential.
The submarine pipeline is the main form for realizing oil and gas transportation between an offshore oil and gas field and a land terminal, and is the life line of the offshore oil and gas field. Once an accident occurs to the submarine pipeline, not only the marine environment is seriously polluted, but also the serious economic loss is caused, so that the submarine pipeline needs to be protected and treated.
The ditching is a very economic and efficient measure for protecting the submarine pipeline, so that the influence of submarine water flow on the pipeline can be avoided, and the stability of the submarine pipeline is improved; and the possibility of damaging the sea pipe when other ships are anchored can be avoided. Therefore, trenching protection of subsea pipelines has become an integral part of the offshore field construction process today.
In order to solve the above problems, we have made a series of improvements.
