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.
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.
In line with the environmental vision of the Belgian shipowner Fast Lines, Wärtsilä’s EnergoProFin has been installed on the fixed pitch propeller of the coaster vessel Fast Jef and reduce the fuel consumption by up to two per cent.
In the highly competitive shipping industry, every drop of fuel matters. Thanks to the good economic benefits stated by Wärtsilä and a favourable price, the owners of the 190-metre-long and 32-metre-wide vessel decided to install the Wärtsilä EnergoProFin.
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.
