ABSTRACT:
A system for laying subsea pipelines. The pipeline to be laid is wound on a reel which is rotatably mounted on a support structure. Both the support structure and the reel with the wound pipeline are submergible to a seabed. Both members are intended to be expendable in that once they are submerged and mounted on the seabed, they are not subsequently salvaged. After the support structure with the accompanying reel have been secured to the seabed, the pipeline is drawn off of the reel from its fixed location towards the desired termination point for the pipeline.
