Wärtsilä EnergoProFin
Energy saving device for fuel savings

The Wärtsilä EnergoProFin is an energy saving propeller cap with fins that rotate together with the propeller. This solution provides average fuel savings of 2%, with a payback time of less than one year.

The propeller’s energy losses are among the factors related to the flow phenomena around and behind the propeller boss. Installing the Wärtsilä EnergoProFin helps to reduce these energy losses and increase overall propulsion efficiency.

The Wärtsilä EnergoProFin is suitable for all newbuilds and existing vessels. 

Key benefits

  • Reduction of the propeller hub vortex resulting in average fuel savings of 2% to 5%
  • Reduction of underwater noise
  • Reduction of vibration
  • The EnergoProFin can be installed underwater without taking the vessel out of service

    Technical info

    The Wärtsilä EnergoProFin is an energy saving propeller cap with fins that rotate together with the propeller. It improves propulsive efficiency by weakening the hub vortex, and by recovering kinetic energy from the rotating flow aft of the propeller blades.

    Application

    The Wärtsilä EnergoProFin is suitable for new build and existing vessels; fixed pitch propellers of any propeller brand and controllable pitch propeller for Wärtsilä brand propellers only.

      Rising fuel prices in recent years have made propulsion efficiency even more important than before. Paccship (UK) Ltd. is a company that is continuously looking for better ways to reduce fuel costs. When they recently installed the Wärtsilä EnergoProFin propeller cap on one of their cargo vessels, they were immediately able to reduce their fuel consumption.
