Seabed oil and gas transportation hose line fixed on the basis of anchor pier

Abstract

The invention discloses a flexible offshore pipeline for oil and gas transportation stabilized on seabed by anchorage piers. It comprises cable (1) and flexible pipe (2) for oil and gas transportation, anchorage pier assemblies (3) to prevent the cable from drifting, and constraining assemblies (4) to restrict the flexible pipe (2) are sequentially provided on the cable. The anchorage pier assembly (3) comprises a gravity block (31) and the first clamping tool (32), and the first clamping tool (32) connects with the cable (1). The invention uses the flexible pipe (2) to build up offshore pipeline for oil and gas transportation, and anchorage pier assembly (3) and constraining assembly (4) for constraining the flexible pipe (2) are sequentially provided on the cable (1), which can restrict the flexible pipe, achieve reliable oil and gas transportation and prevent the flexible pipe drifting on the seabed. The pipeline system can protect the flexible pipe, are strong and reliable and the cost of pipeline is low. It also has the advantages of being safe and easy and fast to installation.

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 ...
