(CNN)A hole was gouged in the deck of Russia’s only aircraft carrier, the Admiral Kuznetsov, Tuesday when a crane fell on it while the vessel was undergoing repairs in the northern city of Murmansk, according to Russian state media.
The accident took place after a power supply disruption caused the pumps on the floating dry dock, which was holding the aircraft carrier, to break down, causing the structure to sink.
The dock, known as PD-50, is one of the world’s largest floating dry docks and the biggest in Russia, measuring 330 meters long (1,082 feet) and weighing more than 80,000 tons.
