Modernization for Two Swedish Icebreakers
Protacon, a company based in Jyväskylä, Finland, informs it has received an order from Swedish Maritime Administration for the modernization of electric and automation systems of two icebreakers. The contract entrusts Protacon with the modernization of electric propulsion drives and drive control systems for the Swedish icebreakers, Atle and Frej. The Swedish Maritime Administration wants to uniform the techniques of its icebreakers to facilitate their usability and maintenance, Protacon said. The modernization will naturally also improve the reliability of operation and increase the service lives of the ships. Now approximately 40 years old, Atle and Frej will gain a remarkably longer lifespan.

The modernization will significantly extend the service life of the ship, which was originally launched into sea in 1976. "Together with the highly successful Urho project [a sister ship], Ymer's 16.2 MW DC electrical drives provide strong evidence of Protacon's knowhow of large electric drives.

The modernization work the icebreaker Urho will undergo is the largest ever done to the ship. It will take about four years work and will start immediately. The renovation work will concentrate in the renewal of the automation and electric systems. This includes among other things a new machinery alarm system…
