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.
"Recognizing Finland’s established leadership in #icebreaker design and construction, the Participants intend to collaborate on icebreaker modernization efforts and related shipyard and workforce development."
Taking our technology partnership two steps forward. 🤖
Minister @elinavaltonen & @SecRubio met in DC to discuss Russia’s war of aggression against Ukraine and to strengthen 🇫🇮🇺🇸 economic ties. They signed the Technology Prosperity Deal & the Framework on Critical Minerals.

Congratulations @RMCFinland for lauching the third Pohjanmaa-class multi-purpose corvette today!
I guess now there's a free slot in the construction hall for the first @USCG #ArcticSecurityCutter... 🙂

Few updated on Russian #icebreaker and high ice class ship projects: light auxiliary icebreaker Svyatogor for the Russian Navy launched; Arc7/Arc5 hydrographic survey vessel Pavel Mikhalenko for Rosatom also progressing.

Few years ago, I made a #KnowYourIcebreakers thread about the Project 21180M auxiliary #icebreakers. Svyatogor is the second vessel in the series.
A near western equivalent in terms of displacement and #icebreaking capability would be USCGC Mackinaw.

Since a new Russian Navy #icebreaker is bound to make some waves in the media in these days, let's take a closer look at Evpatiy Kolovrat and find out what kind of #icebreaking vessel it is and what are its operational capabilities.

It's again time to review this year's #NorthwestPassage transits in the customary #ArcticPassion News article.
It's again the usual mix of expedition cruises and ice-strengthened freighters together with a few oddballs.

Starting next year, we'll probably stop focusing solely on complete transits along the #NorthwestPassage and start looking at all types of #Arctic shipping operations.

This weekend, the UK's polar icebreaker #RRSSirDavidAttenborough departed the UK for #Antarctica, and @BAS_News's aircraft fleet began to touchdown at Rothera Research Station. The 2026/27 Antarctic science field season is officially underway!

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.
globaltimes.cn/page/202610/1…
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.
The reason why I'm wondering who's buying these is that the applicable Russian #icebreaker projects that we know of — IBSV02, 21900M2 and 23680 — all have azimuthing propulsion units that are rated for 8–9 MW and the other details don't really match either.
EU's Arctic Strategy calls for mapping industrial capabilities and Arctic operational needs, strengthening technological leadership, and supporting joint procurement and resource-sharing to improve the availability of advanced #icebreakers across Europe.

Here's also @lvmfi's English-language announcement about two new homeports for the Finnish #icebreakers:
valtioneuvosto.fi/en/-/14108…
The Finnish #icebreaker fleet will be spread out after the 2026–2027 #icebreaking season.
LVM on ohjannut Arctia Oy:tä sijoittamaan murtajia nykyistä useampaan paikkaan ja lähemmäksi Perämeren operointialuetta.
Jäänmurtajien kotisatamat tulevat olemaan jäänmurtokauden 2026–2027 päättyessä Helsinki, Pori ja Kemi.

ALT Kuvassa on ministeri Lulu Ranne ja hänen sitaattinsa: ”Jäänmurtajien sijoittelua on arvioitu uudelleen muuttuneessa toimintaympäristössä. Uusilla kotisatamilla varmistetaan, että murtajat ovat ensisijaisesti siellä, missä niitä tarvitaan 24/7.”
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.
The red dot is CCGS Imnaryuaq's design #icebreaking capability on the h-v-curve of Project 22220 nuclear-powered icebreakers.
💪
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.

The full-scale ice trials report of the 60-megawatt Project 22220 nuclear-powered icebreakers can be found here:

Oh, and for the record CCGS Imnaryuaq's propulsion power will be "just" 34 megawatts.
Projektin kannalta kriittinen jäänmurtajaosaaminen on luonnollisesti peräisin täältä Vuosaaren perukoilta. Toimitamme myös yhden jäänmurtajan kolmesta potkurista.
