ABSTRACT:
A method and apparatus are provided for laying an offshore pipeline or flowline bundle to a deepwater subsea structure. The pipeline or flowline bundle is laid along a prescribed path, preferably U-shape, such that a pullhead at the terminus of the pipeline or flowline bundle falls just short of the subsea structure. A pull-in tool connected to the pipeline or flowline bundle by a short length of pull cable is then landed on and latched to the subsea structure, and the pipeline or flowline bundle is pulled up to the subsea structure by the pull-in tool and pull cable.
