  • System and method for abandoning and recovering pipeline
    Patent number: 6729802
    Abstract: A method of abandoning a pipeline (2) being laid by a vessel having an A/R system, wherein a sealine (2, 11, 13) is initially held by a pipe laying and tensioning arrangement. The method includes a step of reducing tension at sea level of the sealine (2, 11, 13), by connecting one or more buoyant members (13) to the end of the pipeline (2). The members (13) are then lowered into the sea, using a line (16). At least one member (13) is connected to the pipeline (2) through a connection (12) which allows pivoting of the member (13) so that the end of the member (13) at the end of the pipeline (2) projects upwardly from the seabed (3).
