Industry-first electric propulsion concept ABB Dynafin™ mimics
the movements of a whale tail for ultimate efficiency, enabling
new vessel designs
Designed to contribute to shipping industry’s goal of cutting
annual greenhouse gas emissions by at least 50 percent by 2050
Independent study confirms new technology is set to reduce
propulsion energy consumption by up to 22% compared to
conventional shaftline
ABB today introduced ABB Dynafin™, a new concept representing a
revolutionary propulsion system breaking new ground for
efficiency in the marine industry. Inspired by the dynamic
motions of a whale’s tail, the innovative concept is the result
of over a decade of research, development, and testing. ABB’s
combined extensive experience and expertise in the marine
industry, along with its innovative heritage, are the driving
forces behind this new concept. ABB estimates the first
prototype to be available in 2025.
“ABB Dynafin™ shows what is possible when marine engineers
pursue radical innovation and progress, inspired by the
interplay of evolution and technology,” said 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.”
The new propulsion concept features a main electric motor that
powers a large wheel rotating at a moderate 30-80 rounds per
minute. Vertical blades, each controlled by an individual motor
and control system, extend from the wheel. The combined motion
of the wheel and blades generates propulsion and steering forces
simultaneously, enabling ground-breaking operational efficiency
and precision for ships. The concept follows ABB’s proven design
philosophy in marine propulsion of gearless power transmission.
An independent study of ABB Dynafin™ from OSK-ShipTech A/S of a
passenger vessel design equipped with different propulsion
solutions has verified savings in propulsion energy consumption
of up to 22 percent compared to conventional shaftline
configuration. This can deliver significant savings in fuel
consumption and help to avoid emissions. As part of an electric
propulsion power system, the concept is also fully compatible
with zero-emission battery and fuel cell technologies.
Initially available in the power range of 1–4 MW per unit, the
new propulsion concept is particularly effective for
medium-sized and smaller vessels, including ferries for
passengers and vehicles, offshore support vessels operating at
wind farms, and yachts. By reducing vibrations and noise levels,
the system improves passenger and crew comfort. In addition, the
propulsion concept delivers superior maneuverability, and
positioning performance, i.e., the capacity of the vessel to
maintain the desired position and heading.
The new concept is the latest addition to ABB’s portfolio
comprising electric, automated and digital technologies. With
its market-leading expertise in electric and hybrid propulsion,
the company has been pushing the boundaries of technology, and
driving efficiency, performance, and sustainability to new
levels through the 30-year plus track record of Azipod®
propulsion. The new propulsion concept will complement the
existing propulsion portfolio.
The shipping industry contributes to almost 3 percent of global
greenhouse gas emissions annually. If it were a country, it
would be the sixth largest emitter. However, with about 90
percent of global trade being carried on ships, it is central
for the movement of goods. If no action is taken, shipping could
be responsible for up to 13 percent of global emissions by 2050.
At the same time, the International Maritime Organization has
set the goal to cut annual greenhouse gas emissions by at least
50 percent by 2050, against 2008 levels. While there is
consensus in the industry that no single solution can provide a
‘silver bullet’, low-carbon fuels, alternative power sources,
data analytics and energy-saving devices all have a part to
play, and the role of new innovations may become notable.
