ABSTRACT:
The free ends of two pipelines lying on the sea bed are joined by raising both ends to above the surface and supporting them on a barge, bringing them into axial alignment and welding them together by inserting a spool piece if necessary. The welded line is then lowered back to the sea bed and the barge moved sideways.
