ABB has introduced ABB Dynafin™, a new cycloidal propeller concept with individually controlled blades. The operating principle allows the unit to utilize a trochoidal blade path which is analogous to the movement of a whale tail.

Based on modelling and pre-launch studies, the ABB Dynafin concept is expected to achieve an open water efficiency level of up to 85%. Translating the open water efficiency into a fuel savings, ABB expects to be able to deliver a fuel consumption saving of 15-22%. The first full-scale prototype is estimated to be available for pilot installation in 2025.
