ABB Dynafin
Cycloidal-type electric propulsion concept with individually controlled blades mimicking a whale's tail; open-water efficiency up to 85% in CFD and model tests, verified by MARIN, for newbuilds and retrofits.
Description
ABB Dynafin™ is an electric ship propulsion concept based on a cycloidal propeller with individually controlled blades. The blade trajectories mimic the motion of a whale's tail, generating propulsion and steering forces simultaneously. It is the result of over a decade of research, development and testing.
How it works
- A main electric motor drives a large wheel rotating at 30–80 rpm, following ABB's gearless power transmission philosophy.
- Vertical profiled blades project from the bottom of the ship; each blade has its own motor and control system.
- Each blade rotates around the wheel axis and around its own pivot axis with a prescribed pitch motion, giving high propulsive efficiency.
- Thrust direction can be changed almost instantaneously for precise manoeuvring and positioning.
Performance
- Open-water efficiency of up to 85% shown in CFD and model tests; efficiency verified by MARIN (Maritime Research Institute Netherlands).
- Independent study by OSK-ShipTech A/S of a passenger vessel design showed propulsion energy savings of up to 22% compared with a conventional shaftline.
- Individual blade control allows minimization of underwater radiated noise and vibration.
Applications
- Medium-sized and smaller vessels: passenger and cargo vessels, offshore vessels and yachts
- Double-enders, with load sharing between aft and bow or rudder modes
- Dynamic positioning operation, with station keeping at lower power consumption
- Newbuilds and retrofits
