Deep Sea Dangers: Submarine Disasters Highlight Risks


Bangkok (AP) — The disappearance of an Indonesian submarine off the resort island of Bali follows dozens of other disasters at the vast ocean depths of the world. Military secrets limit public access to accident details that indicate that technological advances are still not comparable to the dire risk of being very deep. A Search continues Frida In the case of y KRI Nanggala 402, there is growing concern that the oxygen supply left for the 53 crew members is less than a day and can be left behind in waters that are too deep to reach or recover. This also applies to past submarine disasters. Here are some of them:

___

14 crew members Russian nuclear submarine It occurred in the Barents Sea in 2019 due to toxic gas from the fire. The Kremlin did not reveal the name of the submarine, but Russian media said it was a nuclear research vessel called the Losharik designed for sensitive missions up to 910 meters (3,000 feet) deep.

Russia lost 20 crew members on a nuclear-powered Nerpa, part of the Pacific fleet, in 2008 after the fire system was accidentally triggered.It was Russia’s most deadly submarine accident after the explosion caused the sinking Kursk On August 12, 2000, a Navy submarine killed all 118 crew members.

Argentine ARA San Juan disappeared on November 15, 2017 and returned to Mar del Plata’s base after a military exercise, killing all 44 crew members. The wreckage was discovered almost a year later during a search by Ocean Infinity in the United States, about 900 meters (3,000 feet) east of Patagonia’s Valdes Peninsula. Legislative investigations have found that disasters are not due to attacks or clashes, but to Navy commander inefficiencies and budgetary restrictions. The submarine was cut in half when it was refitted in 2008-14, experts said it could have jeopardized its safety.

The Great Wall of China 361 in China was reported to have been lost in the sea between Shandong Province and North Korea in 2003. When the submarine’s diesel engine broke down and consumed all of its oxygen, 70 people on board were suffocated. This was the first time China had announced a fatal submarine accident.

___

France, Israel, the United States and the Soviet Union all lost their submarines in 1968. France’s Minerve was not discovered until 2019, when it was discovered in the waters east of its home port, Toulon. Two days after the Israeli Navy’s INS Dakar disappeared on the eastern Mediterranean coast with more than 60 people on board, it sank into the rough seas. The location of the submarine was unknown until 1999, at 2,900 meters (9,500 feet) below the surface between Crete and Cyprus. That year, the Soviet Union’s K-129 and USS Scorpion were also lost.

France also lost the Daphné-class submarine Eurydice and its 57 crew members when it exploded off the coast of Toulon in 1970.

___

The most deadly U.S. submarine disaster was the sinking of nuclear power USS threshing machine On April 10, 1963, all 129 crew members on board died during a test dive in the Atlantic Ocean about 360 km (220 miles) from Cape Cod, Massachusetts. Documents published in 2020 showed that the submarine collapsed when it descended more than 240 meters (800 feet). Disasters have helped improve safety.

Australian AE1 submarine Lost off New Britain’s New Guinea in September 1914, along with 35 crew members from Australia, New Zealand and the United Kingdom, when the Allies were first defeated on the seabed in World War I. It was located 300 meters (984 feet) below sea level only in December 2017. , 103 years later.

Indonesian Navy officials say an electrical failure may have prevented the KRI Nangara 402 from resurfaced using emergency procedures. At a depth of 50 to 100 meters (165 to 330 feet), the discovery of an unidentified object with high magnetic force in the area raised hope that it could be a missing submarine. However, the Navy said it could be 600-700 meters (2,000-2,300 feet) much deeper than the depth of the collapse — the depth at which the water pressure would be greater than the hull could withstand. That’s right. The ship’s collapse depth was estimated to be 200 meters (655 feet) by a Korean company that remodeled the ship between 2009 and 2012.
