ABB has launched brand new Azipod (podded propulsion) technology at the SMM trade show in Hamburg, Germany this week which they say achieves a ‘leap’ in efficiency through being up to 10 percent more efficient than previous versions.
The Azipod XL can achieve 5-10% energy efficiency savings compared with its previous XO model, on which the latest design is based, and features simple modifications to ensure ease of use.

Azimuth propulsion works by drawing water into the propeller and pulling the vessel, therefore the addition of a nozzle will optimize the water flow as it leaves the propeller. The new ABB azipod functions using a linear flow to reduce turbulence and energy loss while giving the vessel optimum thrust and can be designed to give a high bolard pull thrust at lower speed to improve performance and increase fuel efficiency. The modular design also means that it has 360-degree maneuverability, meaning that it is suited to a wide range of vessels.
The Azipod XL also benefits from diver-free seal replacement capabilities to increase efficiency and reduce maintenance time.
According to ABB, the Azipod XL has the potential to save the shipping industry 2.2 million tonnes of fuel and 7 million tonnes of CO2 over the next 25 years if it were to replace all existing Azipod units.
They believe that the improved efficiency and bollard pull will expand its appeal beyond established strong markets.
