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