Polaris, the most environmentally friendly diesel-electric icebreaker ever built, was delivered today by Arctech Helsinki Shipyard. The Finnish Transport Agency handed over the vessel, which is named after the North Star, to the state-owned Arctia Icebreaking Oy. Polaris features an IMO Tier III and Baltic Sea Sulphur Emission Control Area (SECA) compliant dual-fuel power plant capable of using both liquefied natural gas (LNG) and low-sulphur marine diesel oil as fuel. The special hull form and propulsion arrangement with three azimuth propulsion units – two in the stern and one in the bow – is designed to minimize ice resistance and maximize the icebreaking capability of the vessel. The main missions of Polaris are icebreaking and escort operations in all prevailing ice conditions in the Baltic Sea. She is also able to perform oil spill response operations, emergency towing and rescue operations at open sea year round. Polaris is based on the Aker ARC 130 concept developed for the Finnish Transport Agency by Aker Arctic in co-operation with ILS Oy. Ice model testing was carried out at Aker Arctic's ice laboratory.
Yesterday, Vyborg Shipyard PJSC laid the keel for Ob, the world’s most advanced port icebreaker, for FSUE Atomflot. Scheduled for delivery in November 2018, the port icebreaker will be stationed in the Sabetta LNG terminal in the Gulf of Ob, part of the Yamal LNG megaproject. Ob will be the world’s first vessel to feature Wärtsilä 31 type main engines, recently recognized as the world’s most efficient four-stroke diesel engine, as well as a propulsion system consisting of four azimuth propulsion units: two in the stern and two in the bow. The power distribution system will be based on ABB’s new Onboard DC Grid concept. Aker Arctic developed the Aker ARC 124 port icebreaker concept and is also responsible for the basic design of the vessel. The development of the new vessel concept also included extensive ice model testing at Aker Arctic’s ice laboratory.
These two icebreakers are the latest innovative icebreaker concepts in Aker Arctic’s portfolio. In addition, two icebreaking support vessels based on our Aker ARC 130 A concept, which is a further developiment of the Finnish icebreaker Polaris, are under construction at Vyborg Shipyard PJSC. Currently we are working on the basic design of two vessels, a polar research icebreaker for the Polar Research Institute of China and an Arctic condensate tanker for Guangzhou Shipyard International Company Limited.
