Energy Saving Devices -
Improve your vessel performance

As awareness of the work required to meet the requirements for 2030 and beyond grows, Wärtsilä has been proactive in developing existing solutions and also innovating and partnering to ensure there are options available to suite all vessel types and operating profiles.

It is clear that propulsion will be a requirement for vessels but in the future that could be achieved in a combination of ways: sails, batteries, fuel cells or smaller engines, for example.  In all probability the prices for bio-based or synthetic fuels will be more expensive than fuel is now, so even when your vessel can operate on these future fuels you will still always need to make it run as efficiently as possible. In this way, increasing propulsion efficiency is only going to become more important as we continue towards a zero-carbon future for the industry​.

  • MV Arvika
    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.

  • Fast Jef
    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.

  • Pac Alkaid
    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.
