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)
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 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

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
