Abstract:

The disclosure provides a method and system of coupling end-to-end at least two existing mooring lines (A, B) that are already deployed from the floating platform () to the seabed or other connecting structure to create a single shared line from the two lines. The shared lines then form a single looped line with both ends deployed to the subsea connections. The shared length provides enough payout of line to loosen one line sufficiently, while the other line becomes correspondingly tighter using the catenary length of the tight line. In part, the line can be loosened while the other is tightened because the lines are generally in the same overall direction to the seabed, such as in a same quadrant around the platform. Thus, the lines share their available lengths to provide the necessary payout for the repairs.
