ABB AZIPOD ELECTRIC PROPULSION CUTS FUEL COMSUMPTION

An independent study by marine consultancy Deltamarin revealed that the ABB Azipod electric propulsion system for ferries could save up to $1.7 million in annual fuel costs per vessel, strengthening Azipod propulsion’s market-leading position in sustainable marine technologies.
By simulating a transit on seven existing ferry routes, researchers found that a ferry equipped with twin 10 MW mid-power range Azipod units consumed less fuel compared to a similar vessel powered by a traditional shaftline propulsion system. Lower fuel consumption also means that the Azipod-powered ferry would reduce CO2 emissions – by approximately 10,000 tons per year. This is equivalent to the amount of carbon dioxide emitted by about 2,200 passenger cars annually.
The global ferry industry, which transports 2.1 billion passengers every year, according to trade association Interferry, is facing increased pressure to meet the International Maritime Organization’s target of reducing annual emissions by 30 percent by 2025.
To help ferries improve energy efficiency and lower emissions, ABB is launching a new series of mid-power range Azipod propulsion systems in June 2019. The latest Azipod series will be available in the 7.5 to 14.5 MW power range and will fill the gap between the low and high-power range of Azipod propulsors already in the market.
The Azipod propulsion system, where the electric drive motor is in a submerged pod outside the ship hull, can rotate 360 degrees to increase maneuverability and operating efficiency, and has a proven ability to cut fuel consumption by up to 20 percent compared to traditional shaftline propulsion systems. Due to minimal noise and vibration, Azipod propulsion also improves passenger and crew comfort. Azipod propulsion systems have accumulated more than 15 million running hours, saving over 700,000 tons of fuel in the passenger cruise segment alone.
The latest Azipod M series is equipped with ABB’s fourth generation permanent magnet motors that draw on proven Azipod propulsion technologies and have been refined to further increase power and maximize efficiency. The design simplicity of the system provides increased robustness and reliability, at the same time allowing for ease of maintenance.
