Search ongoing for Indonesian submarine believed to have sunk too much

A search is underway for an Indonesian submarine believed to have sunk too deep to be recovered.

There are 53 people aboard the submarine, which was participating in a training exercise off the coast of Bali when a scheduled report call was missed.

Ships from the Indonesian navy and rescue ships from neighboring countries are searching for the ship, but the navy said it believes it may have sunk to a depth of 600-700 meters, much deeper than its collapse depth, which it is estimated at 200 meters, according to a firm that overhauled the vessel in 2009-2012.

Authorities reported an oil stain and the smell of diesel fuel near the starting position of the last dive of the diesel-powered KRI Nanggala 402, about 60 miles north of Bali, although there has been no clear evidence that they are linked. to the submarine.

Ahn Guk-hyeon, an official with South Korea’s Daewoo Shipbuilding and Marine Engineering, said that most submarines collapse if they enter more than 200 meters due to pressure on the hull.

He said his company updated much of the Indonesian submarine’s internal structures and systems, but currently lacks information on the ship because it has not been involved in any work on the ship in the past nine years.

Frank Owen, secretary of the Australian Submarine Institute, also said the submarine could be too deep for a rescue team to operate.

“Most rescue systems really only have a capacity of about 600 meters,” he said. “They can go deeper than that because they will have a margin of safety built into the design, but the pumps and other systems associated with that may not have the ability to operate. So they can survive that depth, but not necessarily operate. “

The Indonesian military said five navy ships and a helicopter participated in the search, while a hydro-oceanographic reconnaissance ship equipped with underwater detection capabilities is heading to the site around the oil spills.

Rescue ships from Singapore and Malaysia are expected to arrive on Saturday. The military said Australia, the United States, Germany, France, Russia, India and Turkey have also offered assistance.

Singapore’s Defense Minister Ng Eng He confirmed that he had dispatched his submarine rescue ship. “Our fervent prayers and hopes are with the KRI Nanggala crew, for their safety and endurance,” he wrote on Facebook.

The Indonesian navy said a power failure may have occurred during the dive, causing the submarine to lose control and unable to carry out emergency procedures that would have allowed it to resurface.

He was rehearsing for a missile launch exercise that was to take place on Thursday.

The German-made submarine, which has been in service in Indonesia since 1981, was carrying 49 crew members, its commander and three gunners, the Indonesian Defense Ministry said.

It was serviced and serviced in Germany, Indonesia and most recently in South Korea, from 2007 to 2012.

Indonesia currently has a fleet of five submarines and plans to operate at least eight by 2024.
