A vessel with a mooring tube assembly with swivel mounted chain supports. The assembly includes a frame arranged and designed for support within a vertical opening of the vessel at its bow and/or its stern. A plurality of chain tubes are carried on the outer side of the frame in an arc such that their top ends extend upwardly generally parallel to the vertical axis of opening of the vessel. The vessel includes a deck mounted above the upper end of the frame. A track on the deck allows a single winch to be moved so that a pull-in line can be registered with any of the top ends of the tubes. A plurality of chain supports are rotationally mounted on the frame where each chain support has an outlet and an inlet. A trunnion chain stopper is provided between the outlet and inlet of the chain support. The outlet of each chain stopper is in registration with the lower end of one of the chain tubes.

An arrangement for providing fluid communication between an offshore hydrocarbon production and/or storage facility and an offshore loading system such as a CALM buoy is disclosed. A pipeline from a FPSO or production platform runs to a submerged flowline termination buoy which is positioned beneath and separated a short distance from a CALM buoy. The flowline termination buoy is separately anchored to the sea bed from the CALM buoy, and is at a depth below the turbulent zone of the sea. The end of the pipeline is suspended from the flowline termination buoy, and a marine hose fluidly connects the end of the pipeline to a stationary part of a fluid swivel on the CALM buoy. The arrangement isolates the end of the pipeline from fatigue inducing motions of the CALM buoy.
