ABB introduces electric propulsion system for marine vessels

Azipod XL, the latest version of ABB’s podded electric propulsion system, further increases vessel fuel efficiency by up to 20% compared to modern shaft line propulsion systems. The efficiency gain is achieved by a unique nozzle system that accelerates the water flow into the propeller to increase thrust, and by redesigning the thruster for reduced water resistance. Since the first installation 25 years ago, Azipod propulsion systems have accumulated more than 12 million running hours with an availability of 99.8%, saving over 700 000 tons of fuel, thus helping to reduce the maritime carbon dioxide footprint.
An industry standard for the marine industry, Azipod propulsion is a gearless steerable propulsion system with the electric drive motor located in a submerged pod outside the ship hull. Having 360° manoeuvrability, it is used to steer and drive a broad variety of vessels.
“We continuously strive to advance our technology to the benefit of our customers and the environment, as part of our Next Level strategy. Azipod XL is a perfect example for this approach as it represents the biggest jump in the systems’ fuel efficiency in recent years,” said Peter Terwiesch, president of ABB’s Process Automation division. “To put it in perspective, replacing all existing Azipod units with the new model would save the shipping industry an additional 2,2 million tons of fuel and 7 million tons of carbon dioxide over the next 25 years.”
The Azipod XL concept can be designed to give high bollard pull thrust at lower speed and still have good characteristics at higher speeds. Thus it fits vessels such as tugs and offshore construction vessels. Other suitable ship types are ferries and LNG tankers.
Azipod XL’s features include the capability for advanced condition monitoring utilising ABB’s concept of the Internet of Things, Services and People (IoTSP) and its Integrated Operations Centers for Marine, continuously monitoring equipment and performance parameters of more than 600 vessels.
