This is more than a boring corporate account.

We enthusiastically cover everything related to #icebreakers — not just our own projects — and are happy to answer your questions.

We try to maintain an overall positive vibe.

Occasionally there are also pictures of our office dog.

@iperala If I were to hazard a guess, I'd say about 15,000 tonnes of displacement.

Who is building an #icebreaker with Chinese 10-megawatt azimuthing propulsion units on an "European" yard? 🤨

There's a longer article on @globaltimesnews, but it does not have any further details.

China's first domestically developed high-power podded propulsor designed for polar icebreaking vessels rolled off the production line in Shanghai on Tuesday.

Often described as the "heart" of polar vessels, the 10-megawatt podded propulsor is expected to arrive at a European shipyard in late November before being installed on a vessel in February 2027. It can operate at 160% of its rated torque under icebreaking conditions and break through ice up to 2.1 m thick, including 20 cm of snow cover. Its all-electric propulsion system and 360-degree rotating design enable icebreaking in both forward and reverse directions.

Part of CCGS Imnaryuaq's high operational #icebreaking capability is due to its modern twin-azimuth hybrid propulsion configuration — our patented Hybrid DAS™ solution.

There's an #ArcticPassion News article about that as well.

https://t.co/OJpYGkg7MG

[Railotech @Railotech]

Of course we just published an #ArcticPassion News article about using level ice #icebreaking capability as a benchmark for comparing #icebreakers.

However, CCGS Imnaryuaq is an excellent all-rounder and in many ways superior to the old triple-shafts.

Now that CCGS Imnaryuaq has been laid down at @Seaspan, it's perhaps worth it to remind everyone just how good #icebreaker Canada is building.

Oh, and for the record CCGS Imnaryuaq's propulsion power will be "just" 34 megawatts.

@Megafauna51 @scottpolar You were right — Tiberborg headed to the Panama Canal.

It's time to kick off the #NorthwestPassage transit tracking thread for the 2026 shipping season.

@Megafauna51 @scottpolar Makes sense.

However, it would be really nice to see Nordica escorting Tiberborg through the Northwest Passage as the last vessel of the season.

I still remember looking at the ice "zipping up" Nordica's wake when we were the last ship through the Northern Sea Route in 2012.

Kanadassa on eilen juhlittu rannikkovartioston uuden polaarimurtajan kölinlaskua.

CCGS Imnaryuaq tulee valmistuessaan olemaan Pohjois-Amerikan suurin jäänmurtaja ja yli 2.5 metrin jäänmurtokyvyllään yksi maailman suorituskykyisimmistä jäätämurtavista aluksista.

[Railotech @Railotech]

Projektin kannalta kriittinen jäänmurtajaosaaminen on luonnollisesti peräisin täältä Vuosaaren perukoilta. Toimitamme myös yhden jäänmurtajan kolmesta potkurista.

Looks like I had used the "old" names for the two CCG AOPS variants.

Some early Canadian press releases referred to them as CCGS Donjek Glacier and CCGS Sermilik Glacier:

However, "Glacier" has since been dropped from the names:

Quick update of some #icebreaking fleet timeline charts.

Admiral Makarov and Krasin have been downgraded to subarctic icebreakers.

USCG's light domestic icebreakers (existing 65' WYTL and future HSC-L) continue to be excluded due to their size.

Otherwise business as usual.

We’re pleased to share that we have brought another safe and successful shipping season to a close. The final convoy left Milne Port on October 10, 2026, at 6:30 pm.

This year, we safely loaded 48 ore-carrying vessels, including 4 Capesize and 8 Baby Capesize ships. These Capesize ships are more than twice the size of our other carriers, which allow us to move more cargo with fewer ships, fewer transits and lower CO2 emissions.

As in previous years, we implemented strict adaptive mitigation measures, including delaying the start of the shipping season until icebreaking was no longer required, vessels travelled in convoys, when possible, to reduce overall underwater sound, and ships continued to limit their speeds to an industry leading 9 knots. These measures were reached in direct response to ongoing consultation with Inuit and in full compliance with our commitments.

As in years past, this shipping season also included several monitoring programs including the Marine Mammal Aerial Survey Program (MMASP) and the Rocky Reef and Aquatic Invasive Species and Non-Indigenous Species (AISNIS) Program.

Thank you to all Baffinland team members who worked diligently to make this year’s shipping season a success!
