Three Finnish icebreakers return to service after being repaired at Turku Repair Yard
Finnish icebreaker fleet of Arctia Ltd prepares for winter navigation and icebreaker support in advance. In early September Turku Repair Yard launched a small "flotilla" of ships of the Finnish state-owned company Arctia Ltd - icebreakers Voima, Otso and Polaris – after repairs.
On the world's oldest operating icebreaker Voima, in addition to the routine repairs, a set of operations was carried out to maintain the vessel's operability: full overhaul of stern StB and PS propeller shafts, dismantling/mounting of intermediate shafts, thrust bearings and propellers, propeller shafts withdrawal and Cederwall sealing renewal.
Icebreaker Polaris arrived at Turku Repair Yard for drydocking in mid-August. It is the most powerful icebreaker ever to sail under the Finnish flag. Built in 2016, the vessel is the first environmentally friendly dual-fuel icebreaker powered by low-sulphur marine diesel and LNG. Vessel has outstanding manoeuvrability thanks to two aft and one forward Azipod thrusters which underwent full overhaul.
The icebreaker Otso underwent a small repair of the underwater part, and now the vessel is ready for winter navigation.
