Yamalmax is a class ofice navigationtankers for the transportation ofLNG with maximum dimensions that allow passing through the approach channel of the port ofSabetta located on theYamal Peninsula (channel width 295 m (968 ft), depth 15.1 m (50 ft)). The project was developed by the Finnish companyAker Arctic by order ofSovcomflot.[citation needed]
Vessels correspond to theice class Arc7 (Independent navigation in close-packed first-year Arctic ice with their thickness up to 1.4 m (4 ft 7 in) in winter-spring navigation and up to 1.7 m (5 ft 7 in) in summer-autumn with occasional overcoming of ice barriers by raids. Navigation in the channel behind theicebreaker in annual Arctic ice up to 2.0 m (6 ft 7 in) thick in winter-spring and up to 3.2 m (10 ft) in summer-autumn navigation).[1]
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.[2] Constant power regardless of the direction of movement is achieved by using theAzipod propellers produced by the Swedish-Swiss companyABB. Each Yamalmax ship is equipped with three rudder propellers with a total capacity of 45 MW.[3]
