About
Railotech's roots go back to the first Finnish ice model test basin, built in 1969. For three decades the work was part of the Finnish shipbuilding industry; in 2005 the accumulated Finnish ice-technology know-how was consolidated into the independent company Aker Arctic Technology. In 2025 the company acquired Bluetech Finland, and Aker Solutions, one of its founding companies, divested its stake. In March 2026 the company became Railo Technology; "railo" is Finnish for an ice lead.
Railo Technology Oy and its sister company Bluetech Finland Oy are owned by Arctic Marine Technology Group Oy. Fifty-nine icebreaking ships built at 11 shipyards are based on its designs, with 36 more under development. Its innovations include the Double Acting Ship (DAS) concept and the oblique icebreaker Baltika.
