ABSTRACT:
A discharge manifold system is provided for connecting a pressurized fluid discharge from a floating vessel to an offshore well. A floating buoy is anchored at a distance away from the offshore platform. A first manifold is located on the floating buoy and includes an inlet and first and second outlets. A second manifold is located on the production platform adjacent the offshore well and includes first and second inlets and an outlet which is connected to the offshore well. First and second valves are connected to the outlets of the first manifold. Third and fourth valves are connected to the inlets of the second manifold. A first flexible intermediate conduit is connected between the first and third valves and a second flexible intermediate conduit is connected between the second and fourth valves. The first, second, third and fourth valves, and the first and second flexible intermediate conduits comprise a means for providing selectable redundant fluid communication between the floating vessel and the offshore well. A high pressure treating fluid discharge from the floating vessel is directed to the inlet of the first manifold through a flexible discharge conduit connected to the fluid conducting swivel. This allows the floating vessel to rotate 360.degree. about the floating buoy during the pumping operations.
