Recently there have been delivered and designed new icebreakers, icebreaking shuttle tankers, container vessels and LNG carriers. Many of these vessel concepts are relying on podded propulsion system. Azipod propulsion has been selected to many of these vessels as it provides excellent ice performance for the vessel, good torque characteristics for the propeller and there already exists proven track record of ice operations.

Currently the demand for even bigger icebreaking vessels with higher capacity is increasing. Due to increasing market need ABB Marine have further developed Azipod propulsion concept to meet the demands of arctic ice classes and power requirements of more than 15 000 kW per thruster unit. This paper will give an overview of 25 year of development of azimuth podded propulsion, Azipod, for icebreaking vessels and introduce latest breakthrough projects in arctic shipping.
