A buoy recovery system for a disconnectable mooring arrangement that permits turret-buoy connection at any compass heading while preventing damage to the pull-in line and the turret assembly. In a preferred embodiment, the mooring tensioning assembly is positioned on the vessel at a location other than on the rotatable turret assembly. This permits the size of the turret assembly to be significantly reduced and the fluid swivel stack to be positioned within the vessel between its deck and keel. The improved buoy recovery system employs a hollow bore hydraulic cylinder assembly that is attached to the turret assembly and configured as a chain tensioning system. The hollow bore hydraulic cylinder assembly is arranged and designed to support the weight of the buoy and permit the turret assembly to be rotated relative to both the vessel and the buoy during mooring operations.
