Damen Introduce Double-Bow LNG Arctic Ship Concept

Damen Shipyards Group (Damen) says it is introducing a concept for a new Arctic vessel capable of running on liquefied natural gas (LNG).

The Damen Arctic Modular Towing Supply Vessel (AMTSV) concept, which comes from a project by maritime engineering students at the Delft University of Technology in the Netherlands, offers the ability to sail through 1.6 metres of level ice at 3 knots and can operate year-round in the Barents Sea and for eight months out of the year in the Baffin Bay and Beaufort Sea.

The dual fuel engines with the capacity to use LNG fuel were chosen for environmental reasons, but storage of the fuel presented a problem because of the extra space required.

The students developed the idea of placing the LNG tanks externally, on top of the enclosed superstructure, something made possible by the heavy hull needed for ice strengthened vessels, which makes the ship's centre of gravity relatively low.

The vessel also has two bows, one optimised for travel through open water and the other for sailing through ice.

Interest in the development of Arctic oil and gas has been on the rise as melting ice makes the region more accessible, with energy companies like OAO Rosneft making plans for exploration and logistics companies developing services to support the industry.
