@TeppoLundell @RTSaloX @TeroTweet @raumafi @RMCFinland Legendat ovat oleellinen osa Suomen meriteollisuuden historiaa ja joskus niissäkin on ripaus totuutta mukana.

Juuri eilen pohdimme Suomen Laivahistoriallisen Yhdistyksen kokoontumisessa niitä kuuluisia Neuvostoliittoon toimitettuja kuparilauteita.

@TeppoLundell @RTSaloX @TeroTweet @raumafi @RMCFinland Eikö Wärtsilä Marine ehtinyt mennä konkurssiin jo ennen kuin Hollming rakensi ensimmäistäkään miinalaivaa tai ohjusvenettä Raumalla... 🤔

Arkistoa siivotessa löytyi muutama Wärtsilän rakentaman jäänmurtajan erittelyn kaksoiskappale. Kiikutin nämä Suomen Laivahistoriallisen Yhdistyksen kirjastoon muidenkin iloksi.

Laatikossakin on näemmä vanha nimikyltti — eihän me enää mikään Aker Arctic olla...

In our latest #ArcticPassion News article, we revisit the invention that revolutionized #Arctic shipping: the Double Acting Ship (DAS™) principle.

The old Karhu-class #icebreakers — Karhu, Murtaja and Sampo — were retired from #icebreaking in the mid-1980s as too small to assist modern tonnage.

I know there's a little bit of perspective here, but the size difference to Polaris is quite striking!

🇺🇦🚢 The fifth Antarctic season of the Ukrainian research ice class vessel Noosfera has officially come to an end.

On 28 May 2026, the vessel returned to Cape Town, South Africa, after completing its most ambitious season yet — and setting multiple records along the way.

🔹 More than 7 months at sea
🔹 9 Antarctic voyages completed
🔹 18 crossings of the legendary Drake Passage
🔹 Over 30,000 nautical miles traveled — farther than the Earth’s equator

This season also marked a historic milestone for Ukraine’s Antarctic research: Noosfera crossed the Polar Circle twice to conduct scientific work in Marguerite Bay, expanding Ukraine’s research area farther south than ever before.

On board, Ukrainian scientists together with international colleagues studied the impact of climate change on the Southern Ocean — from marine heatwaves and geological history to changes in marine ecosystems and microbial loop interactions.

The season became a record-breaker for international cooperation as well. Ukraine collaborated with Poland, Czechia, the UK, the USA, Canada, Colombia, and Mexico. In particular, Noosfera and Vernadsky base hosted the First Mexican Antarctic Expedition, strengthening scientific ties between our countries.

The vessel also traditionally carried out the crew rotation for the 30th and 31st Ukrainian Antarctic Expeditions and transported seasonal teams to and from Vernadsky station.

This demanding mission was accomplished by a team of Ukrainian sailors led by captains Pavlo Panasiuk and Andrii Starish, skillfully navigating storms and iceberg-filled waters.

“Noosfera has become not only a symbol of Ukraine’s openness to new international partnerships, but also a place where global science is developed together to protect the fragile ecosystems of our planet,” said Evhen Dykyi, Director of the National Antarctic Scientific Center.

What a season. ❄️🌎

This short video is from another project but shows the same simplified ship model moving through a brash ice channel consisting of "real" ice cubes instead of our FG(X) model ice.

#DYK we do more than just design #icebreakers?

In our latest #ArcticPassion News article, we look into our recent and ongoing R&D projects.

https://t.co/HFjD3HUdBd

[Railotech @Railotech]

Some of these R&D projects were funded by the Winter Navigation Research Board and the reports are publicly available on their website. Three new reports were published recently and there are a few more in work.

Three new Winter Navigation Research Board reports from our research and test engineers: model test procedure update (No. 136), IBeam (No. 137) and OreDCs (No. 138).

Strength and agility: meet our icebreakers! 🚢

From the St. Lawrence all the way to the #Arctic, these powerful and versatile vessels keep commercial shipping lanes open, support northern communities, and safeguard maritime safety no matter the conditions.

Baltika teki siis kaiken mitä luvattiin — ja paikoin yrittikin jäänmurtokykyvaatimukset melkoisella marginaalilla. Näitä oppeja on sittemmin hyödynnetty muissakin jäänmurtajaprojekteissa, vaikkei lisää vinomurtajia olekaan toistaiseksi rakennettu.

Itämerelle suunnitellun Baltikan ensimmäinen pitkä rahtaus oli öljyterminaalin standby-aluksena Obinlahdella. Sen jälkeen se oli ensin pitkään samoissa hommissa Prirazlomnajan tuotantotasanteella Petšoranmerellä ja nyt viimeisimpänä Sahalinin öljykentillä Venäjän kaukoidässä.
