Vessel owners are facing the twin challenges of ensuring compliance with the IMO’s Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Index (CII) measures while also needing to improve operational efficiency in order to remain competitive. Wärtsilä EnergoFlow is an innovative pre-swirl stator that improves a vessel’s propulsive efficiency by creating an optimal inflow for the propeller, reducing both fuel consumption and emissions.
Wärtsilä EnergoFlow creates optimal inflow for the propeller by guiding one side of the stern flow in the opposite direction to the propeller rotation, generating pre-swirl. The solution consists of multiple curved fins and a ring attached to the ship’s hull to prevent the power losses that typically occur in a propeller’s slipstream.
