The STL system
Vessels planned for use with the submerged turret loading (STL) system are specially equipped with mating equipment for the submerged buoy.
The STL buoy system includes a trunk in the forward part of the vessel which houses the turret buoy mating cone and swivel system adapted for high pressure natural gas. A vessel equipped with STL equipment is capable of staying moored to the transfer system at a location offshore and perform its send-out function in severe weather conditions.
The Submerged Turret Loading or STL turret mooring and transfer system is designed by APL - Advanced Production Loading - of Norway. The technology has proved its reliability through many years of nearly uninterupted operation in the North Sea in extremely harsh weather conditions.
