Self-propelled icebreaking bow

ILS P999

ILS conceptual & basic design

ILS developed the concept as a partner in the EU CEF funded Winter Navigation Motorways of the Sea II (WINMOS II) Action.

Solution that transforms ice strengthened vessels and larger tugboats into icebreakers. Investment cost of the bow is about 25 % of the price of a purpose built icebreaker.
