Problems solved by technology

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 cost is also higher and higher.

Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, the hose pipeline for subsea oil and gas transportation in the embodiment of the present invention includes a cable 1 and a hose 2 for oil and gas transportation, and the cable 1 is sequentially provided with anchors for connecting with the seabed Pile assembly 3 and restraint assembly 4 for restraining hose 2 .

[0023] Such as image 3 As shown, the anchor pile assembly 3 includes a first clamp 31 and a pipe pile 32 hinged to each other, the first clamp 31 is connected to the cable 1 , and the pipe pile 32 is inserted and fixed on the seabed. In this embodiment, the first clamp 31 and the pipe pile 32 are hinged to each other through a pin 33 . The structure of the anchor pile assembly 3 is simple and reliable, and the way of hinged connection can make the pipe pile 32 reach the seabed in a vertical state all the time, which is convenient for the pipe pile 32 to be fixed on the seabed. The pipe pile 32 is provided with a ca...

Abstract

The invention discloses a flexible pipeline for undersea oil transportation and gas transportation, which comprises a cable and a flexible pipe for oil transportation and gas transportation. An anchor pile assembly for being connected with the seabed and a binding assembly for binding the flexible pipe are arranged on the cable in sequence. The anchor pile assembly comprises a first fixture and apipe pile hinged together, the first fixture is connected with the cable, and the pipe pile is inserted and fixed on the seabed. The binding assembly comprises a binding belt and a second fixture arranged on both ends of the binding belt, the end parts of the second fixture are provided with locating slots, and the cable is clamped and fixed in the locating slots. The flexible pipe is sheathed inthe binding belt of which the head and the tail are connected on the cable. The flexible pipeline provided by the invention is safe, reliable and convenient and easy to construct and has the advantages of high construction speed and 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 ...
