SUBSEA PIPELINE CONNECTING APPARATUS AND METHOD

摘要

A method and connecting apparatus for attaching a pipeline termination assembly to a subsea structure. The pipeline termination assembly has a pivot axis member and the subsea structure has one or more capture slots to receive it. The pivot axis member is captured in the capture slot, the slot allowing vertical movement of the pipeline termination assembly. The pipeline termination assembly is rotated about the pivot axis to assume a horizontal position. In the horizontal position, the capture slot permits horizontal movement of the pipeline termination assembly. A capture device mounted on the subsea structure provides the capture slots. At least a part of the capture device is moved with respect to the subsea structure to retain the pivot axis member in the capture slot on rotating the pipeline termination assembly about the pivot axis.
