Nuclear-powered icebreaker
On 17 August 1977, NS "Arktika" ("Arctic") became the first surface ship ever to reach the North Pole. "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles. Rather than be scrapped, there are calls for her to be converted to a museum ship, like her predecessor "Lenin".
Drillship
From the first drillship CUSS I to the Deepwater Asgard the fleet size has been growing ever since. In 2013 the worldwide fleet of drillships tops 80 ships, more than double its size in 2009. Drillships are not only growing in size but also in capability with new technology assisting operations from academic research to ice-breaker class drilling vessels. U.S. President Barack Obama's decision in late March 2010 to expand U.S. domestic exploratory drilling seems likely to increase further developments of drillship technology.
