Wärtsilä Corporation (Wärtsilä) today announced the launch of EnergoFlow, an energy-saving solution that the company says will return ship operators' investment in less than two years.

Wärtsilä says the "next-generation" pre-swirl stator reduces power losses that occur in a propeller's slipstream with an optimised inflow to boost fuel efficiency by as much as 10 percent.

"Wärtsilä's solution enables the accurate directing of the pre-swirl flow. This in turn supports our customers in their fuel saving efforts by lowering resistance," said Tamara de Gruyter, Vice President, Propulsion System Services at Wärtsilä.

"As the result of increased propulsive efficiency and subsequent energy savings, Wärtsilä EnergoFlow reduces the emissions of ships. Investments in energy-efficient solutions ensure cost savings, compliance with maritime regulations and reduced environmental footprint."

The company notes that the impact of EnergoFlow on fuel consumption is the greatest on bulk carriers, tankers, and other full form vessels.
