Icebreaker
In May 2007, sea trials were completed for the nuclear-powered Russian icebreaker NS . The vessel was put into service by Murmansk Shipping Company, which manages all eight Russian state-owned nuclear icebreakers. The keel was originally laid in 1989 by Baltic Works of Leningrad, and the ship was launched in 1993 as NS "Ural". This icebreaker was intended to be the sixth and last of the "Arktika" class, and currently is the world's largest icebreaker.
Royal Arctic Line
The three largest ships the "Naja Arctica" (782 Twenty-foot equivalent unit (TEU)), "Nuka Arctica" (782 TEU), and "Mary Arctica" (588 TEU) are principally used for the Aalborg route. The "Irena Arctica" (424 TEU), "Arina Arctica" (283 TEU), and "Pajuttaat" are used within Greenland and have equipment for unloading in cities without harbors. All these container ships are double-hulled and built with high freeboards and the highest ice ratings: the "Mary Arctica" has even been chartered for Antarctic service. The settlement ships "Angaju Ittuk", "Anguteq Ittuk", "Aqqaluk Ittuk", and "Johanna Kristina" are all older and smaller (220–320 m³) and used for supplying the smaller ports. In 2011, the ships had an average on-time rate of 72%.
