ABSTRACT:
A multiport swivel joint suitable for use in loading a tanker at an off-shore mooring terminal comprises a plurality of toroidal or doughnut-shaped conduits which are horizontally arranged and vertically spaced along a common vertical axis. Each toroidal conduit comprises an inner fixed section and an outer section which is arranged for rotation about the common axis, with a suitable rotary seal between the inner stationary and the outer rotatable sections of the toroidal conduit. Inlet connections are made for each fluid stream to a separate one of the inner stationary sections, while the corresponding outlet connections are made at the rotatable outer sections, each of which communicates with and rotates with the tanker about the mooring terminal.
