The Mangystau-2 is a light icebreaker. Until November 2021 it was part of the fleet of Atlantic Towing Limited, a firm with headquarters in New Brunswick, but with vessels operating around the world. The Mangystau-2 was last in Hazar, Turkmenistan, on the Caspian Sea.
On November 10, 2021 she was purchased by the Government of Canada, to join its fleet of icebreakers. Upon some conversion work she is scheduled to join the Canadian Coast Guard icebreakers CCGS Samuel Risley and CCGS Griffon on the Great Lakes. She cost $45 million CAD.
The Coast Guard recently three medium icebreakers, and added them to its aging fleet. The Canadian Press noted that the Coast Guard's existing fleet is extremely old, and that while some new vessels have been ordered their completion will take years. It suggested that the purchase of used vessels, that are still newer than the Coast Guard's purpose built fleet, is a stop-gap measure.
She was built in 2010 by Aker Arctic with four sister ships, named ''Mangystau-1, Mangystau-3, Mangystau-4, Mangystau-5. They were designed to operate at the relatively shallow depth of 2.5 metres.
She was delivered in October 2010. Her maximum speed is 12 knots. Her gross tonnage is 1828 tonnes.
