Integrated propulsion and electrical systems to maximize performance and energy efficiency of icebreaker expected to operate in 2 meters of ice at minus 35 degrees Celsius
ABB, the leading power and automation technology group, recently won an order worth $35 million from the Baltic Shipyard Ltd. to supply powerful propulsion and energy efficient electrical systems for a new icebreaker vessel under construction for Russia’s state shipping company Rosmorport FSUE. The order was booked in the third quarter of 2012.
The 25 megawatt (MW) line diesel-electric icebreaker is the next-generation multifunctional dieselelectric icebreaker. The navigation area of the icebreaker is the Northern Sea Route, the Arctic seas and estuaries of rivers discharging into the Arctic Ocean. The icebreaker is able to proceed continuously both ahead and astern at the speed of 2 knots in compact ice field up to 2m thick with 20 cm of snow cover and temperatures as low as minus 35 degrees Celsius. Considerable gains in energy efficiency can be achieved using an Azipod® propulsion system, with up to 20 percent fuel reduction.
The delivery schedule is due to start in 2013 and the vessel will be delivered to Rosmorport in 2015.
“The extreme conditions north of the Arctic Circle demand constant availability and high-energy efficiency from all systems on board,” said Veli-Matti Reinikkala, head of ABB’s Process Automation division. “ABB’s solutions will ensure the reliability and maneuverability required for this type of ship’s operation. This agreement represents a very significant milestone for us, underlining our excellent reputation in the Russian market as a long-term, reliable partner and reinforcing our global leadership in supplying propulsion for icebreaking vessels.
ABB will provide integrated power generation and distribution systems, thruster motors, fire-fighting pump motors as well as 25 MW propulsion systems. The propulsion system of the vessel features two Azipod® thruster units (power output 2 x 7,5 MW) and one centerline arranged shafting with a fixed pitch propeller generating additional 10MW output. All Azipod® propulsion units for this project are specifically designed for extreme Arctic ice class RMRS Icebreaker-8.
