Rationale and technical development of the ABB Dynafin™ concept

Growing concern over climate change has sharply increased the demand for greener solutions in the global shipping industry to limit greenhouse gas (GHG) emissions.

The International Maritime Organization (IMO) has issued resolutions to cut GHG emissions by 50 percent by 2050, compared to 2008 levels, however it will be challenging to achieve this target without major technological advances in fuel technology, adopting alternative energy sources such as batteries and fuel cells, and in propulsion technology. Because of these and other increasingly strict regulations, there will be a high demand for viable solutions that can significantly reduce emissions from vessels in the future. ABB Marine & Ports is committed to conceiving and delivering low-emission and energy-saving solutions to help solve this challenge. Our latest innovation is ABB Dynafin™ – a new, highly efficient cycloidal-type propulsor concept designed to meet the urgent demand for even higher efficiency and emission reduction requirements.

Today, almost all vessels still rely on screw propellers for propulsion, and even though there is still space for efficiency improvements in such systems, these are considered to be more or less incremental. In contrast, the new, fully electric ABB Dynafin™ concept has been developed to achieve very high propulsive efficiency, which will directly translate to lower fuel consumption and lower emissions.

In addition to high efficiency, the concept will enable superior vessel maneuverability. These two benefits can significantly lower operating expenses for vessel operators, as well as increase safety at sea. The concept also means that fuel consumption can be reduced regardless of the fuel type used.
