NEW ON BOARD New concepts for Polar ships to be expected from Aker Arctic by: MERJA KIHL AND ARI MONONEN New Finnish icebreakers represent top-notch high technology. Many of them have been designed especially for the demanding Polar operating conditions.    With a laboratory for ice model testing in Helsinki, Aker Arctic Technology Inc. has a long history of the development of the technology for ships to be used in challenging ice conditions. Some new concepts are again taking shape on the company’s CAD screens and drawing boards.
