An icebreaker by Finland’s Arctech Helsinki Shipyard, will travel through the ice sideways, in order for to clear a wider path, for other ships to travel through the ice.
The NB 508 asymmetric-hulled icebreaker, also known as the Baltika, was designed by Aker Arctic Technology for the Russian Ministry of Transport, will be also used for rescue and oil spill cleanup.
It’s scheduled for delivery to the client by next spring.
“The ship will be moved along by three propulsion on its underside, each one of which can rotate 360 degrees. This means that it will have no problem moving forwards, backwards, or sideways.
By hitting the ice at an oblique angle, it will be able to clear a 50-meter (164-foot)-wide path – not too shabby, considering the NB 508 itself will have a breadth of only 20.5 m (67 ft), and a length of 76 m (249 ft).
Three diesel generators will provide a total power of 9 MW and a total propulsion power of 7.5 MW. That should be enough to send it through ice up to 0.6 meter (2 ft) thick when moving sideways, or 1 meter (3.3 ft) when going bow- or stern-first.”
