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.
Double acting ship
The double acting ship concept has been selected as the main transportation concept for the Yamal LNG project. In July 2013, Daewoo Shipbuilding & Marine Engineering (DSME) won the tender for the construction of sixteen Arc7 ice class LNG carriers and the contract for the first vessel, worth 339.3 billion won ($316.4 million), was signed in March 2014. The Arctic LNG carriers, fitted with three 15MW ABB Azipod propulsion units, are the largest icebreaking vessels in the world with an independent ice-going capability in level ice up to in thickness. The first vessel, "Christophe de Margerie", was launched in January 2016.
