Daewoos technology cuts fuel consumption

Daewoo Shipbuilding and Marine Engineering (DSME) has unveiled an energy-saving device that it says will help lower vessels? operational costs with improved speed and reduced fuel consumption. The ?Pre-swirl Stator? was first installed on H.5297, a Kristen-owned 320,000 dwt VLCC and sea trials showed the stator helped increase the vessel?s speed by 0.2 knot and reduced fuel consumption by 4% DSME claims. The stator is placed in front of the propeller and will be installed on approximately 20 vessels including VLCCs and container ships by improving the inflow angles to the propeller, thus maximising propeller efficiency.
