An independent study for ABB by marine consultancy
Deltamarin has found that the ABB
Azipod electric propulsion system for ferries could save up to $1.7 million
in annual fuel costs per vessel.
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. Thanks to this lower fuel consumption, ABB says an
Azipod-powered ferry could reduce CO2 emissions by approximately
10,000 tons per year, equivalent to about 2,200 passenger cars per year.
ABB says the global ferry industry 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, the company is launching a new series of mid-power range Azipod
propulsion systems in June 2019. The latest series will be available in the 7.5
to 14.5 MW power range and will fill the gap between the low-power and
high-power range of Azipod propulsors already in the market. With this
expansion, the Azipod propulsion family now covers the power range of 1-22 MW.
In the Azipod propulsion system, the electric drive motor is
in a submerged pod outside the ship hull. It can rotate 360 degrees to increase
maneuverability and operating efficiency. According to ABB, the system is proven
to cut fuel consumption by up to 20% compared to traditional shaftline
“We are continuously strengthening our portfolio of
electric, digital and connected solutions that maximize the potential of ships
and ultimately enable more sustainable operations,” said ABB Presient Peter
Terwiesch. “With the launch of the mid-power range Azipod propulsion, we will
be able to empower more shipowners to improve the performance of their vessels
while lowering environmental impact.”
