Baltika (icebreaker)
''Baltika'' ( rus, Балтика) is a Russian icebreaker built by Arctech Helsinki Shipyard in Helsinki, Finland. She is the first ship ever built with an asymmetric hull that allows her to operate not only ahead and astern, but also obliquely (sideways) with a large angle of attack. In this way, the relatively small oblique icebreaker is capable of opening a wide channel in ice for large merchant ships. The vessel was initially scheduled for delivery to FGI Gosmorspassluzhba, the Russian Marine Emergency Rescue Service, in early 2014. However, she remained moored at Kaliningrad until late 2014, when the vessel was towed to St. Petersburg, and was finally accepted to service in December 2014.Rosmorrechflot accepts into service oblique icebreaker Baltika PortNews, 30 December 2014. |
Oblique Icebreaker
An oblique icebreaker is a special type of icebreaker designed to operate not only ahead and astern, but also obliquely (sideways) with a large angle of attack. In this way, a relatively small icebreaker is capable of opening a wide channel in ice for large merchant ships. The oblique icebreaker concept was developed in the late 1990s by Kværner Masa-Yards Arctic Technology Centre (MARC), the Finnish engineering company also responsible for the development of the double acting ships. The first vessel of this kind was ordered by the Russian Ministry of Transport on 8 December 2011 and was completed in 2014. Development The development of the oblique icebreaker concept began in 1997, when Kværner Masa-Yards Arctic Technology Centre (MARC) established a project to develop new ways of assisting large tankers in ice conditions. Traditionally, escorting large ships up to wide required two conventional icebreakers with a beam of , a practice that was not very efficient and econom ...
