Innovative Dynafin Biomimetic Maritime Propulsion Inspired by Whale Motion

In a significant milestone for maritime propulsion, Swiss engineering giant ABB has developed a revolutionary biomimetic technology inspired by the graceful swimming motion of whales. The ABB Dynafin propulsion system replicates the efficient swimming techniques of cetaceans, potentially transforming how vessels navigate the seas. This innovative approach, which features a horizontal motorized wheel with individually controlled vertical blades mimicking a whale’s tail movement, has shown impressive results in testing at the Maritime Research Institute Netherlands (MARIN).

The Dynafin system achieves up to 81% efficiency in open-sea conditions at a cruising speed of 18 knots, thanks to advanced control technologies derived from ABB’s robotics expertise. This onboard brain constantly adapts its performance to maximize efficiency, making it suitable for vessels in the 1-4 MW power range per unit like passenger ferries, offshore support vessels, small cargo ships, and luxury yachts. The system’s environmental impact is also significant, with potential fuel consumption reductions of up to 22% and proportional decreases in CO₂ emissions, aligning with the International Maritime Organization’s ambitious targets for carbon neutrality by 2050.

By integrating robotics expertise with biomimetic design principles, ABB’s Dynafin system represents a paradigm shift in maritime propulsion. Inspired by nature’s efficient locomotion methods evolved over millions of years, this technology offers a promising path forward for shipping companies facing pressure to reduce emissions while maintaining operational efficiency. The elegant swimming motion of whales, translated into a sustainable propulsion system, exemplifies how the natural world continues to inspire significant technological breakthroughs in the quest for a more environmentally friendly future in ocean transportation.
