Aker Arctic has developed a tender design for the next generation Baltic escort icebreaker for the Swedish Maritime Administration and the Finnish Transport Infrastructure Agency. The new icebreaker will be capable of assisting larger merchant ships, incorporates latest environmental technologies, and is ready for future fossil-free fuels.
In the first phase of the project, Aker Arctic developed multiple concept alternatives with different propulsion configurations. The overall efficiency of each variant was evaluated with extensive life cycle cost (LCC) and life cycle assessment (LCA) calculations. In addition, three concept alternatives underwent model tests in both open water and ice to verify their icebreaking capability and ability to escort merchant ships in close-coupled towing. In the end, the concept alternative incorporating three azimuthing propulsion units – one in the bow and two in the stern – was selected for further development. The propulsion design is similar to the 2016-built Finnish icebreaker Polaris, also an Aker Arctic design.
The final Aker ARC 130 S design has been developed in close co-operation with the Swedish Maritime Administration and the Finnish Transport Infrastructure Agency. It combines decades of operational experience from Swedish and Finnish icebreakers with Aker Arctic’s latest design experience and methods.
