Oxygen supply to the 53 crew members of the Indonesian submarine, which went missing in the waters off Bali, was supported by the arrival of an Australian warship equipped with sonar, and there were signs of the ship while the search resumed. It is believed that it disappeared at the beginning of Saturday.
KRI Nanggala 402 went missing after the last reported dive leaving the resort island on Wednesday. The Navy Commander said the submarines were expected to run out of oxygen early Saturday morning.
Maj. Gen. Ahmad Riad told reporters on Friday, “We will maximize today’s efforts until the time limit of 3 am tomorrow.” The press conference was scheduled for late Saturday morning.
There were no signs of life from the submarine, but the family wanted a large search effort to find the ship in time.
“The family is in good shape and continues to pray,” said Ratich Wardhani, sister of the 49-year-old crew Wisnu Subiyantoro. “We are optimistic that Nangara can be rescued by all crew members.”
After the submarine disappeared during the exercise, 24 Indonesian vessels and patrol aircraft were mobilized for the search, focusing on the area where the oil slick was found. Rescue teams have made similar large searches in the last two days.
An American reconnaissance aircraft, the P-8 Poseidon, is expected to join the search on Saturday, with a second Australian vessel scheduled shortly.
“These two Australian vessels will help extend the scope of the search and extend the duration of the search,” said Maj. Gen. Mark Hammond of the Australian Navy.
Rescue vessels in Singapore and Malaysia were also expected within the next few days.
Indonesian President Joko Widodo has canceled a visit to Banyuwangi Port, where several rescue vessels departed earlier, in preparation for a weekend regional summit in Jakarta, officials said. He asked the Indonesians to do their best to find the submarine and pray for the safe return of the crew.
“Our top priority is the safety of our 53 crew,” Widodo said in a speech televised Thursday. “The crew’s family can understand your feelings. We are doing our best to save the entire crew.”
There was no conclusive evidence that the oil slick was from a submarine. Admiral Yud Margono, Chief of the Navy, said oil could have spilled from a crevice in the submarine’s fuel tank, or the crew could have released fuel and liquid to reduce the weight of the ship and bring it to the surface. ..
According to Margono, the unidentified object showing high magnetism is 50 to 100 meters (165 to 330 feet) deep, and authorities want it to be a submarine.
The Navy, however, believes that the submarine sank to a depth of 600-700 meters (2,000-2,300 feet), much deeper than the depth of collapse, which results in higher water pressure than the hull can withstand. Stated. 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.
The cause of the disappearance is still unknown. The Navy said an electrical failure could have prevented the submarine from performing emergency procedures to resurface.
Submarine accidents are often disastrous.
In 2000, the Russian nuclear submarine Kursk was sunk by an internal explosion during its maneuver in the Barents Sea. Most of the 118 crew members died instantly, but 23 men fled to the rear compartment before they died later, mainly due to suffocation. In November 2017, an Argentine submarine went missing in the South Atlantic Ocean with a crew of 44. Almost a year earlier, the wreckage was found at a depth of 800 meters (2,625 feet).
However, in 2005, seven men on board a Russian mini-submarine were rescued nearly three days after being caught in fishing nets and cables in the Pacific Ocean. They had only 6 hours of oxygen left before reaching the surface.
According to the Indonesian Ministry of Defense, the German-made diesel-powered KRI Nanggala 402 has been in use in Indonesia since 1981, carrying 49 crew members, 3 gunners and their commanders.
Indonesia, the world’s largest archipelago with more than 17,000 islands, faces increasing challenges to recent maritime claims, including numerous incidents involving Chinese ships near the Natuna Islands.
