Swiss power and automation technology group ABB has secured a contract to provide power, propulsion and automation for an advanced port icebreaker being built by Russia’s Vyborg Shipyard to support the Yamal LNG project in Siberia.
Under the terms of the deal, ABB will supply the icebreaker with a package consisting of onboard DC Grid, four Azipod thrusters and Power2 800-M two-stage turbocharger.
ABB Group Process Automation senior vice-president Peter Terweisch said: “ABB’s marine applications are at the forefront of the icebreaking market with our process automation technology now central to the world’s most advanced icebreaking vessel.
“We are very pleased to be able to deliver industry leading levels of efficiency and safety by providing so many ABB latest generation solutions on one vessel.”
The DC Grid aboard the icebreaker is expected to help the diesel engines to run at variable speeds when managing ice conditions besides reducing fuel consumption and emissions.
Meanwhile, the Azipod propulsion systems are expected to enhance safety, fuel efficiency while also reducing the negative environmental impact.

The Power2 800-M two-stage turbo charging system on the icebreaker’s Wartsila 31 engine will facilitate a low pressure and high pressure stage with higher air pressure ratios up to 12 when compared to eight previously.
The company claims Power2 800-M to be the only system currently available across the large engine industry with 75% efficiency.
Aker Arctic Mika Hovilainen said: “The harbour icebreaker is a totally new concept especially developed for heavy harbor ice conditions with extensive thick brash ice.
“Having four Azipod units helps to take operability, manoeuvrability and ice management capability to one step further.
“Along with ABB Marine and Ports, we continue to be at the cutting edge of icebreaking technology.”
The integration of the power and energy management system and marine automation system into a centralised system is expected to enhance efficiency and safety.
Recently, ABB was awarded a similar contract for the delivery of electrical power plants and propulsion systems for Global travel and leisure company Carnival Corporation’s two new vessels.
Under the terms of the $60m deal, ABB will deliver electric Azipod propulsion systems which have the electric drive motor in a submerged pod outside the ship’s hull.
