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