The US is facing a potential shortfall in icebreaking capability after its only remaining vessel, the ageing Polar Star, suffered an electrical fire on 10 February.
The 43-year-old ship, the only functioning icebreaker remaining in the US fleet, completed a life-extension works in 2013, theoretically allowing it to operate until 2023. But its viability was called into question after a series of incidents during the vesselís return from a resupply mission in Antarctica, which culminated in the fire, which broke out in the incinerator room. Its 150 crew were forced to battle the blaze for two hours, more than 10,000 miles from the Seattle drydock for which it was headed.
ďItís always a serious matter whenever a shipboard fire breaks out at sea, and itís even more concerning when that ship is in one of the most remote places on Earth,Ē said a statement by Vice Adm. Linda Fagan. ďThe crew of the Polar Star did an outstanding job ó their expert response and determination ensured the safety of everyone aboard.Ē
In the lead up to the fire, smoking and power outages were recorded from Polar Starís electrical systems, a propeller shaft sprang a leak, and one of the vesselís two drinking water evaporators malfunctioned. Electrical systems and insulation suffered further damage during the blaze, when firefighters were forced to use water to cool down the vesselís exhaust pipes.
In response to the news, the US federal government allocated new funding for its icebreaking programme in mid-February, comprising $655m for the first new icebreaker and $20m for a subsequent ship. But in 2018, a report by the USí Government Accountability Office stated that the timeline for new icebreakers was ďnot informed by a realistic assessment of shipbuilding activities, but rather driven by the potential gap in icebreaking capabilities once the Coast Guardís only operating heavy polar icebreakeróthe Polar Star óreaches the end of its service life.Ē
Due to enter service in 2023, when Polar Starís service life is due to end, it will be the first time a heavy icebreaker has joined the US fleet for more than 20 years.
But as Seattle drydock begins repairs of the incinerator and various other faulty parts, concerns remain about Polar Starís ability to survive the next four years until its eventual replacement.

Not good. The potential shortfall in icebreaking capability is also an issue in Canada and both countries share icebreaking duties on the Seaway and Great Lakes system. Canadian politicians mess around the icebreaker fleet renewal. We need all icebreakers we can find, not losing another ship...

When you have absolutely no idea what kind of ship you need but yet insist that it should be built at a shipyard that has never built an icebreaker, no wonder it takes more than a decade to procure a single vessel that ends up being also the world's most expensive icebreaker.

With Finland's latest icebreaker, Polaris, it took about 3Ĺ years from concept design contract to delivery of the 125 million euro vessel even though it was the world's first LNG-powered icebreaker and featured a completely new type of propulsion configuration.
