The idea of using bubbles to reduce a vessel’s friction – which is the largest driver of fuel consumption as it moves through the water – has existed for well over a century. Nonetheless, it has taken time to realize. 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. Listen to the story.
