Abstract

The invention discloses a seabed oil and gas transportation hose line fixed on the basis of an anchor pier, comprising a cable and a hose for transporting oil and gas, wherein the cable is sequentially provided with an anchor pier component preventing a hose line from drifting on a seabed, and a restrain component for restraining the hose, and the anchor pier component comprises a gravity block and a first clamp which is connected with the cable. In the seabed oil and gas transportation hose line, the hose is adopted for transporting the oil and the gas, and as the cable is sequentially provided with the anchor pier component and the restrain component for restraining the hose, the hose can be restrained effectively, thereby realizing the reliable transportation of the oil and the gas, and preventing the hose from drifting on the seabed with large displacement. The seabed oil and gas transportation hose line can protect the hose well, is firm and reliable, reliable to install, and convenient and fast in construction and has a low cost.

Description

technical field [0001] The invention relates to the field of offshore operation systems such as offshore oil production and gas production, and in particular to a hose pipeline for transporting crude oil and oil gas on the seabed. Background technique [0002] With the depletion of oil and gas reserves in coastal areas and shallow water areas, the exploitation and production of oil and gas resources in deep water areas has become the goal of marine energy development. Most of the large offshore oil fields discovered so far are located in deep waters, and the exploitation and production of offshore oil and gas resources in countries all over the world are accelerating their development to deeper waters. The submarine oil pipeline is one of the key structures in the deep sea oil production system. As the depth of the submarine oil field deepens, the design, construction and operation management of the traditional steel pipe oil pipeline become more and more difficult, and the ...
