![]() He said the Indonesian sub was not fitted with a special hatch seal that would allow the crew to escape into a different vessel during an underwater rescue. So they can survive at that depth, but not necessarily operate." "They can go deeper than that because they will have a safety margin built into the design, but the pumps and other systems that are associated with that may not have the capacity to operate. "Most rescue systems are really only rated to about 600 meters (1,969 feet)," he told the AP. If the vessel is intact, it could be too deep for a rescue, said Frank Owen, secretary of the Submarine Institute of Australia. "Anything more than that can be pretty fatal, dangerous," he said.Ī Daewoo Shipbuilding official, Ahn Guk-hyeon, told the AP that the submarine would collapse if it goes deeper than about 200 meters (about 655 feet). Navy spokesman Julius Widjojono told Indonesia's KompasTV earlier that the boat could sustain a depth of 250-500 meters (about 820-1,640 feet). Speaking to reporters, the navy chief of staff said the submarine had "received a letter of feasibility from the navy" and that "it was ready for battle." A Daewoo official told The Associated Press that the company had upgraded the boat's internal structures and systems. ![]() Despite its age, a refit of the vessel by South Korea's Daewoo Shipbuilding and Marine Engineering was completed in 2012. The German-built submarine has been in service since the early 1980s. Indonesian President Joko Widodo said Thursday that he had ordered an "optimal" search for the submarine and that the rescue of its crew was the "main priority." He expressed sympathy with family members over their ordeal. It could even be a deliberate signal from the crew. While an oil slick might be a sign that the vessel was destroyed, the navy said it could simply mean that the submarine's fuel tank had been damaged. The KRI Nanggala was conducting a weapons training exercise early Wednesday when the navy said the sub was given permission to dive and then never made radio contact again.Įarlier, rescuers reported finding an oil slick on the surface and the smell of diesel fuel, but there was no way of knowing whether it came from the sub. "Hopefully we can rescue them before the oxygen has run out," he said. "We hope it is the KRI Nanggala," he said.īut the navy had said previously that it believes the submarine may have sunk in a particularly deep spot in the otherwise relatively shallow sea - about 600-700 meters (2,000-2,300 feet) down - much deeper than the boat's maximum operating depth and likely below its crush depth.Įven in a best case scenario, the navy chief of staff emphasized that with oxygen expected to run out early Saturday a quick rescue would be critical. Yudo Margono, told reporters Thursday that a search of the vicinity where the diesel-powered KRI Nanggala 402 is believed to have gone down, about 60 miles north of the resort island of Bali, had located an object with "high magnetic force" floating at a depth of 50 to 100 meters (about 165 to 330 feet). Rescuers scouring the Bali Sea for a stricken Indonesian submarine with 53 sailors aboard are hoping the crew could still be alive, but as the hours since the vessel's disappearance tick by, the chances of survival grow increasingly slim. It is 60 m long and displaces 1,400 tonnes when submerged.An Indonesian navy ship searches for the submarine KRI Nanggala 402 that went missing this week in the waters off Bali. It is one of two submarines of the class operated by the TNI-AL. Nanggala is a German-built vessel that has been in service since 1981. Other ships currently on the scene include the TNI-AL’s Fatahillah (361), Bung Tomo (357), and Teuku Umar (385) corvettes. The TNI-AL has dispatched several vessels to the area to help find the missing boat, including hydrographic ship KRI Rigel (933). Janes understands that the submarine was at that location to conduct a torpedo drill. Nanggala is believed to have disappeared about 26.5 n miles northwest off Singaraja on the island of Bali. Subsequently, the TNI-AL sent out a distress call to the International Submarine Escape and Rescue Liaison Office (ISMERLO) at about 09:37 h to report the boat as missing, with the presumption that it has sunk. Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL) sources told Janes that the missing boat, KRI Nanggala (402), was deemed to be in distress after missing a scheduled reporting call with the TNI-AL at about 03:00 h (local time) on 21 April. , seen here in a file photo, was reported missing in the Bali Sea on 21 April.Īn Indonesian Cakra (Type 209/1300)-class diesel-electric submarine (SSK) has been reported missing and an attempt to find it and rescue the crew is currently under way.
