Modern ice breakers carry out their work in the most extreme conditions that prevail at sea. This makes a durable and reliable propulsion system an absolute must for failsafe travel in conditions that include temperatures of -40 degrees Celsius and howling winds. RENK’s marine propulsion systems provide a reliable basis for ice-going ships and ensure safety at sea – even when the keel is cutting through meters of ice at speeds of up to 16 knots.
