Polaris has been delivered. The liquefied natural gas dual-fuel icebreaker, built by Finland’s Arctech Helsinki Shipyard Inc., was handed over to the Finnish Transport Agency on September 28th, 2016. The Agency in turn passed the vessel to Arctia Icebreaking Oy, the state-owned limited company set up to provide icebreaking and specialised multipurpose vessel services in polar areas.
The prototype 3000 dwt vessel, built at Helsinki Shipyard and classified PC4, is designed to serve for at least 50 years in icebreaking, oil recovery and sea rescue operations. It has been 22 years since a similar-sized vessel has been launched.
Engine specifications: Main engines Wärtsilä 2x 6000 kW, 2x 4500 kW, 1x 1280 kW, Dual fuel.
Icebreaker Polaris is able to use either liquefied natural gas or low sulphur diesel oil as fuel. It has LNG storage capacity of 2 x 400 m3.
The vessel complies with the international IMO Tier III emission standards and special requirement for Sulphur emissions in the Baltic Sea. The vessel is equipped with three Azipod propulsion units rotating 360° which enables first-rate maneuvering qualities. The icebreaking capacity of Polaris is 1,8 m at speed of 3,5 kt.
“Icebreaker Polaris is an extremely versatile vessel that can operate in all ice conditions in the Baltic Sea and use in all circumstances either natural gas or diesel oil as fuel. We are proud we had this opportunity to build the vessel that will serve the Finnish winter navigation in coming decades,” commented the Managing Director of Arctech Helsinki Shipyard, Esko Mustamäki.
