Ice model tests on trimaran icebreaker give promising results

On 27 September 2011, Arctia Shipping and Aker Arctic conducted an ice model test on a next-generation trimaran icebreaker.

Testing was carried out in Aker Arctic's ice testing facility in Vuosaari, Helsinki. The model was first driven into fast ice (one and a half metres thick). After a pause, the test was continued with a tight path cleared through the basin. Icebreaking capability outside the path was also successful.

In a nutshell, trimaran technology’s greatest advantage lies in the need for less power than previously when breaking a wider path through ice.

The technology is still in its early stages. For example, fixing the secondary hulls sufficiently strongly to the primary hull may be highly problematic for the designers.
