Ice breaker for heavy duties

摘要

Aker Arctic Technology has unveiled a new version of the oblique icebreaker ARC 100, the ARC 100 HD. The »Heavy Duty« ARC 100 HD version is 98 m long and 26 m wide. The vessel will draw on 24,000 kW of engine power and 19,500 kW of propulsion power to offer 190 t of bollard pull in open water. This is two-and-a-half times the pull offered by the ARC 100, which is 76 m long. Planned to be classed by the Russian Register as an Icebreaker 7, the design is based on model tests at Aker Arctic, Helsinki. Tests demonstrated that the ARC 100 HD will be able to break through 1.5 m thick ice when moving ahead and astern at 5 kn (2 kn through 2 m thick ice). In the oblique mode, it will be able to cut a 50 m wide channel through 1.5 m thick ice.
