Abstract:
A method and apparatus for direct tie-in of pipelines. An apparatus is attached to a portion of a pipeline 1, the apparatus comprising a tensioning member 2 and a buoyancy element 3 attached to the tensioning member 2 such, that when submerged, the pipeline 1 is deflected as a result of a buoyancy force tensioning the tensioning member 2, and on releasing the buoyancy element 2, direct tie-in of the pipeline is performed.
