Yamalmax is a class of
ice navigation tankers for the transportation of
LNG with maximum dimensions that allow passing through the approach channel of the port of
Sabetta located on the
Yamal Peninsula (channel width , depth ). The project was developed by the Finnish company
Aker Arctic by order of
Sovcomflot.
Vessels correspond to the
ice class Arc7 (Independent navigation in close-packed first-year Arctic ice with their thickness up to in winter-spring navigation and up to in summer-autumn with occasional overcoming of ice barriers by raids. Navigation in the channel behind the
icebreaker in annual Arctic ice up to thick in winter-spring and up to in summer-autumn navigation).
By design, gas carriers of the Yamalmax class are classified as double acting ships - the bow is adapted for navigation in open water and in thin ice conditions, and the stern is optimized for independent navigation in difficult ice conditions. Constant power regardless of the direction of movement is achieved by using the
Azipod propellers produced by the Swedish-Swiss company
ABB. Each Yamalmax ship is equipped with three rudder propellers with a total capacity of 45 MW.
