Damen joins the ice party with new Arctic tug
Damen has launched a specialised supply vessel design for the High North, the Arctic Modular Towing Supply Vessel (AMTSV), capable of operating in 1.6m ice at 3 knots.
June 26, 2013
Due to the 100 m long AMTSV being ice-strengthened, the vessel’s centre of gravity is low enough to allow for large LNG tanks to be placed on top of the superstructure, enabling the vessel to be fully LNG-powered, running on dual-fuel engines.
The design can operate in the Barents Sea year round and in the Baffin Bay and Beaufort Sea for 8 months, with the accommodation capable of keeping the temperature above zero degrees indoors with an outside temperature of -55 degrees.
Azipod technology allows the double-acting design to use its icebreaking stern to travel through ice stern-first. The vessel can then move through open water bow-first, with no loss of hydrodynamic efficiency. The design also includes a 300 tone double-acting winch, enabling the AMTSV to tow in both directions.
The vessel was designed in co-operation with students from the Delft University of Technology, in the Netherlands, and Aalto University in Helsinki, along with DNV, Dutch hydrodynamics and nautical research institute Marin.
