ABB Dynafin was impressed by the dynamic motions of a whale’s tail,
ABB has unveiled a brand new electrical propulsion idea known as ABB Dynafin. Inspired by the dynamic motions of a whale’s tail, it guarantees to scale back propulsion vitality consumption by as much as 22% in comparison with a traditional shaftline.
The new propulsion idea incorporates a primary electrical motor that powers a big wheel rotating at a average 30-80 rounds per minute. Vertical blades, every managed by a person motor and management system, prolong from the wheel. The mixed movement of the wheel and blades generates propulsion and steering forces concurrently, enabling what ABB says is “ground-breaking operational efficiency and precision” for ships. The idea follows ABB’s confirmed design philosophy on marine propulsion of gearless energy transmission.
An unbiased examine of ABB Dynafin by OSK-ShipTech A/S that evaluated a passenger vessel design geared up with totally different propulsion options verified financial savings in propulsion vitality consumption of as much as 22% in comparison with standard shaftline configuration. This can ship vital financial savings in gas consumption and assist to keep away from emissions. As a part of an electrical propulsion energy system, the idea can be totally appropriate with zero-emission battery and gas cell applied sciences.
Initially out there within the energy vary of 1–4 MW per unit, the brand new propulsion idea is especially efficient for medium-sized and smaller vessels, together with ferries for passengers and autos, offshore help vessels working at wind farms, and yachts. By decreasing vibrations and noise ranges, the system improves passenger and crew consolation. In addition, notes ABB, Dynafin delivers superior maneuverability, and positioning efficiency.
The progressive idea is the results of over a decade of analysis, improvement, and testing and ABB estimates that the primary prototype shall be out there in 2025.
“ABB Dynafin shows what is possible when marine engineers pursue radical innovation and progress, inspired by the interplay of evolution and technology,” stated Juha Koskela, Division President, ABB Marine & Ports. “This solution is all about operational efficiency and emissions avoidance, leveraging innovations from the brightest minds in marine and propulsion engineering. I want to thank the whole team for their persistence, resilience, innovativeness, and years of hard work.”
