Description

technical field

[0001] The invention relates to a vertical pile support device for handling the suspended span of a submarine pipeline, which belongs to the technical field of marine equipment. Background technique

[0002] Submarine pipeline is an important part of offshore oil field production system, known as the lifeline of offshore oil and gas field development, and is an efficient, economical and reliable way of oil and gas transportation. Maintaining the safety of submarine pipelines is an important part of ensuring safe production and protecting the marine environment, so protecting the safety of submarine pipelines is particularly important. Compared with land, the seabed environment is relatively harsh. The seawater scours the seabed, the unevenness of the seabed topography, and the residual stress of the pipeline will cause the oil pipeline to overhang. The emergence of the overhanging phenomenon of the submarine pipeline will change the force of the oil pipeline...
