A turret mooring and riser hang-off arrangement, for transferring petroleum products from an off-shore or subsea facility to a vessel, including a turret arranged in a cavity of the vessel. The turret is held firmly in axial and radial directions within the cavity, but is rotatable relative to the vessel. The turret is adapted to be moored to the seabed. A riser assembly extends through a bore in the turret to an upper surface of the vessel. The bore of the turret is a monobore and the riser assembly is rotationally coupled to the turret but is free to move axially relative to the turret. The riser assembly is axially supported by the vessel.
