Alfa Laval adds air lubrication technology with stake in Marine Performance Systems

Alfa Laval has chosen to invest in Marine Performance Systems, whose unique method of producing bubbles with fluidics is a breakthrough that will reduce fuel consumption by 8–12% at a vessel’s normal service speed.

Air lubrication for marine vessels is a developing solution that will radically reduce fuel consumption and environmental impact. Having acquired a minority stake in Marine Performance Systems a Rotterdam-based maritime technology company, Alfa Laval will be instrumental in making this technology a commercial reality.

Alfa Laval has chosen to invest in Marine Performance Systems, whose unique method of producing bubbles with fluidics is a breakthrough that will reduce fuel consumption by 8–12% at a vessel’s normal service speed.

The patented FluidicAL technology requires no structural modifications or vessel recertification, which makes it ideal for retrofitting as well as for newbuilds. Compatible with any vessel size and any fuel type, it comprises evenly spaced bands of oscillators under the vessel’s hull. Using high-efficiency fluidics, each oscillator produces tens of thousands of microbubbles per second, creating a stable, uniform layer of air that significantly reduces friction between the hull and the water beneath.

“The use of fluidics creates a larger air layer of superior quality,” said Frode Lundsteen Hansen, who founded Marine Performance Systems in 2018 with innovators Pieter Kapteijn and Fulko Roos. “Our FluidicAL technology enables truly effective air lubrication, with immediate environmental benefits and substantial savings for shipowners. Alfa Laval shares our belief that this technology will facilitate the transition to green shipping.”

“The investment brings Alfa Laval full circle, since air lubrication technology for marine vessels was first pursued and patented by our founder Gustav de Laval in 1883,” said Sameer Kalra, President, Alfa Laval Marine Division. “The technology did not result in any product in his time, but our founder’s vision has new importance today. Air lubrication will smooth the marine industry’s path to a sustainable future.”

By reducing the amount of fuel burned, air lubrication will have a direct effect on greenhouse gas emissions. In addition, it will provide critical fuel cost savings for shipowners, who need to offset the expense of rapidly shrinking their environmental footprint.

“Fleets cannot be replaced overnight, so existing vessels will need to rely on clean-burning fuels to lower their emissions,” Lundsteen Hansen explained. “In a low-margin industry where fuel represents up to 60% of a shipowner’s costs, the premium price of those fuels is a heavy burden. With very small means, air lubrication can provide significant relief.”

The high performance of FluidicAL technology and its ability to operate in various conditions have already been demonstrated at full scale. In late 2020, a pilot installation was made on the general cargo vessel Tharsis, with excellent results and clear savings over months of operation.

“With our FluidicAL solution in place, Tharsis made 25 controlled runs in loaded and ballast conditions,” said Lundsteen Hansen. “As expected, there was a 60% reduction in specific drag over hull’s flat area, which meant considerably less fuel was consumed. Not only was there no impact on stability or manoeuvrability, the sailing was also noticeably smoother.”

Given the emission-reducing benefits of air lubrication, as well as the fuel economy it offers to shipowners, investing FluidicAL technology is a logical step for Alfa Laval. “This is a unique solution that is relevant for all vessels said Kalra. “We are pleased to have a stake in Marine Performance Systems and the work of bringing their air lubrication solution to customers.”

“We are proud of our innovation and how far it has come,” said Lundsteen Hansen. “With Alfa Laval’s support, FluidicAL technology will soon make positive waves in the marine industry.”
