In his previous work, Alexey was involved in projects related to Kauno began his work at Masa-Yards Arctic Research Centre the design of offshore units and ice-going (MARC) in 1990, where he took care of the centre as well as vessels for the Arctic. This included the prepared and performed ice model tests. He also took part in ice assessment of ice loads and design of the expeditions and full-scale tests. In 2001 he transferred to the appropriate ice reinforcement. His main activities at Aker Arctic are related to the Helsinki Shipyard, but when Aker Arctic was founded in 2005, design of the hull structure of ice-going Kauno's old colleagues persuaded him to join them in Vuosaari, vessels and icebreakers. where the new third generation ice model testing facility was being set up.
