System for offshore loading/unloading of a flowable medium, especially oil

摘要

A system for transferring a flowable medium, especially oil, to or from a floating vessel, comprising a buoyancy unit in the form of a submerged buoy which is anchored to the sea bed by catenary mooring lines keeping the buoy submerged at a desired depth when it is not in use, at least one transfer line which is connected to the buoy, for the transfer of medium, a downwardly open receiving device arranged on the vessel below the water surface and arranged for receipt and connection of the buoy, a hoisting device provided on the vessel for raising of the buoy for introduction thereof into the receiving space, and a device enabling the vessel to turn about a vertical axis through the buoy when this is connected in the receiving space.
