Simply final month we trawled the web for updates to our protection of the Dynafin propulsion concept from marine large ABB. Now the know-how has been independently examined, which additionally provides us our first take a look at the precise system.
ABB says that the Dynafin idea has been in growth for greater than a decade, however a lot of that was out of the general public eye. The venture formally launched in Might 2023. Reportedly impressed by “the dynamic motions of a whale’s tail,” the system includes a motorized disc in horizontal orientation that is house to a lot of vertical blades.
Every of those blades has its personal electrical motor, and the mixed motions of the disc and blades concurrently propel and steer the watercraft that hosts them “to optimize thrust and positioning precision.” ABB reckons the system might result in “substantial gas financial savings and considerably decrease ship emissions in comparison with standard propulsion setups.”

The corporate has beforehand evaluated its know-how on a passenger vessel and a cruise yacht, and it is already been earmarked for a floating battery financial institution referred to as the e-bunker. However as a 2026 industrial launch window looms, maritime analysis institute MARIN has taken the idea for a spin at its Idea Basin testing facility within the Netherlands.
“At MARIN, we measure hydrodynamic forces and moments, and decide hydrodynamic effectivity,” stated the institute’s Jie Dang. The complete-scale Dynafin was mounted to a customized check rig that measured torque, RPM and drive, and lowered into an enormous tank to simulate open water.

The excellent testing of the full-scale 3-MW propulsion unit is claimed to have resulted in an open water effectivity determine of 0.808 for operation at 18 knots (33 km/h, 21 mph).
“ABB Dynafin is all about extraordinarily excessive effectivity, and this mannequin scale testing provides a superb platform for our prospects to confirm its efficiency,” stated Janne Pohjalainen, International Product Line Supervisor for ABB Dynafin. “Our testing has been actually profitable and what we have now seen totally aligns with our expectations from computational fluid dynamics evaluation.”
ABB additionally says that the MARIN assessments affirm the idea’s market readiness, with the primary vessels to make use of the know-how more likely to embrace passenger ferries, small cargo boats, offshore assist vessels and yachts. Preliminary items might be rated for 1 to 4 MW.
