Completed in 1967, Karpaty was designated Project 530, and was known to NATO as the 'Nepa' class. A unique ship among the Soviet Union's large and varied salvage fleet, her stern housed two cranes with a combined lift capacity of 750 tons. She had numerous other cranes and booms, and a submarine rescue chamber can be seen midships on the port side. Karpaty started a refit in 1989, but the work was not finished and by 1994 she was was out of service at Kronshtadt. She remains there today, although there was another short-lived attempt to overhaul the ship after the Kursk disaster.
