Meeting of two icebreakers near the North Pole:

More meetings in the Arctic:

It is not easy to design and built icebreakers, or ice strengthened research ships:

It is not explained when, how and why those extra 10 m. beam was added?

PS> Maybe the ship just grew during “smoko” so nobody from Australian Antarctic Division (AAD) noticed?

That’s the width of the wheelhouse wings that extend beyond the hull which is still 25.6 m wide.

Apparently the key issue here is the turn just before the bridge when sailing out. Nuyina, being an icebreaker, tends to drift* a bit more than normal ships.

(* someone here can probably explain the phenomenon using correct nautical terminology)

USCG Cutter Healy guarding the Russian Arctic coast?:

Hope she make it all the way without any breakdown.

Some updates on the Canadian Coast Guard polar icebreaker project:

Apart from the fact that the project is now progressing again, perhaps the biggest news is the new propulsion layout consisting of two azimuthing propulsion units and a single centerline shaft. This configuration, also used in the USCG Polar Security Cutter, replaces the old design with two wing shafts and a single azimuth thruster in the middle.

Other changes include substituting the specialized high tensile strength steel that had previously been identified as a major risk item:

The Port of Kirkenes has to scrap their icebreaking tug “Kraft Johanssen”:


The reason isn’t that the tug is in bad condition, but because they are unable to find an Engineer willing to take take a job lasting only for 4 months of the year.

The Rossiya, Russia’s first Lider class icebreaker, will have a power of 120 MW and be able to open large lanes for convoys even in thick sea-ice.

A team of 3 ice experts from Hamburgische Schiffbau-Versuchsanstalt GmbH - Hamburg Ship Model Basin just boarded RSV NUYINA, Australia’s new icebreaking research and supply vessel, to carry out ice performance trials near Davis Station, Antarctica. The hull lines of the vessel, built by Damen Schelde Naval Shipbuilding, have been optimized and model tested by HSVA. Our team is happy to also assist in the upcoming ice performance trialsstrong text


Icebreakers await their call at Katajanokka dock in Helsinki. The blue icebreaker on the left is POLARIS, LNG powered.110 metres long and 45 m high. It can run at 6 knots when tackling ice fields 1.2 m thick, and can handle fields of 1.8m without stopping.

Not a Heavy Icebreaker but a research vessel with Polar class 3 capabilities::

The Baltic is experiencing the most difficult ice situation in many years:

Sweden is coping, just:

Russia is dismantling their 1974-built heavy polar icebreaker Ermak to keep its younger sister ships Krasin and Admiral Makarov in service:

They indeed may need some service…

The “Leningrad” will be the sixth in the new class of icebreakers of which “Arktika” was the first. Originally the name was supposed to be “Sakhalin”. Photo: Rosatomflot

I get the feeling they repeatedly asked some AI-based image generator to make the ship look “just a bit more patriotic”…
