Seaspan begins construction on heavy polar icebreaker
This marks the first time a heavy polar icebreaker has been built in Canada in more than 60 years, and it will play a critical role in protecting our sovereignty for decades to come.
Seaspan Shipyards (Seaspan) has cut steel on the Canadian Coast Guard’s (CCG) new heavy polar icebreaker, signifying the start of construction on one of the most advanced conventional polar icebreakers ever to be built.
Measuring 158 metres long and 28 metres wide, Seaspan’s polar icebreaker will be incredibly complex, designed to operate self-sufficiently in the high-Arctic year-round. It will play a critical role in enabling the Canadian Coast Guard to transit and operate on more than 162,000 km of Arctic coastline. The capabilities of this Polar Class 2 icebreaker will help sustain a 12-month presence in Canada’s North in support of Canada’s Arctic sovereignty, high-Arctic science (including climate change research), Indigenous Peoples and other northern communities, and the ability to respond to major maritime emergencies including search and rescue. It will be able to accommodate up to 100 personnel, and, as one of the only Polar Class 2 vessels in the world, will be able to operate farther north, in more difficult ice conditions and for longer periods than any icebreaker in Canada to date.
This built-in-Canada ship will be the seventh vessel designed and built by Seaspan under the National Shipbuilding Strategy (NSS). It will also be the fifth Polar Class vessel to be built for the CCG, and one of up to 21 icebreaking vessels overall that Seaspan is constructing.
In January 2024, Seaspan completed construction of a polar Prototype Block to ensure preparedness to build this highly-advanced vessel, which requires steel that is twice as thick in some areas, while also being less malleable, as the steel Seaspan has used for the other ships built under the National Shipbuilding Strategy.
As the only shipyard currently building polar icebreakers in Canada, Seaspan looks forward to supporting the Canadian Coast Guard by building this large, multi-mission vessel, and through the design and construction of any vessels Canada and its ICE Pact partners need now, or in the future.
