ABSTRACT:
A method and apparatus are provided for connecting an offshore pipeline or flowline bundle to a deepwater subsea structure and then laying away from said structure. The pipeline or flowline bundle is deployed vertically from a pipelay vessel to make a hinged connection with the subsea structure. The connection operation is facilitated by a flowline connection tool attached to the pipeline or flowline bundle and designed to be inserted into a funnel located either centrally or to one side of the subsea structure. The connection procedure consists of landing and securing the flowline connection tool onto the subsea structure, then hinging over and connecting the pipeline or flowline bundle to the subsea structure as the pipeline or flowline bundle is laid on the seafloor beginning at the subsea structure.
