Abstract
For the purpose of mooring a vessel in deep water, as well as to load or discharge a fluid cargo from the vessel, mooring terminals consisting of a buoy anchored to the seabed or a column coupled to the bottom are used. Hoses transfer fluid between the vessel and a fluid swivel in the terminal, allowing 360.degree. rotation of the vessel around the terminal. Pipes and/or hoses from the swivel to a sealed pipeline allow fluid transfer between the ship and any desired location. This invention provides a fluid swivel which has a toroidal shape and can be easily removed from a buoy or column for maintenance, or repair, or replacement.
