SAVER Air is an active fuel-saving device that reduces frictional drag, which accounts for 60-70% of a ship's total resistance, by injecting air into the bottom of the ship.

SAVER Wind(C) is a device that reduces air resistance on voyage condition by installing a structure (wind shield) at the bow through mitigation of the stagnation pressure on front of loaded container boxes.

SAVER Wind(L) is a device that reduces the added resistance by wind during actual voyage condition, providing significant fuel savings.

SAVER Fin is a device that attaches on the stern hull surface to reduce the resistance and the propeller induced vibration.

SARB is a devices that enhances propulsive efficiency of propeller by reducing or eliminating the hub vortex which is primary loss of rotating propeller.

SAVER Stator is a device composed of three or four wing-like blades positioned ahead of propeller that generates a pre-swirl flow in the opposite direction of propeller rotation to increase thrust and improve propulsive efficiency.

SAVER Stator-D is a device developed to further improve propulsive efficiency by combining a partial duct with the SAVER Stator.
