  • Flexible pipeline for oil and gas transportation stabilized on seabed by anchorage pier
    Patent number: 9033615
    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.
