Found Deceased Rescue teams race against time for Indonesian submarine with 53 aboard - Apr 22/2021

[LadyL]

Indonesian navy ships searched Thursday for a submarine that likely sank too deep to retrieve, making survival chances for the 53 people on board slim. Authorities said oxygen in the submarine would run out by early Saturday.

Rescue ships from Singapore and Malaysia are expected to arrive between Saturday and Monday. The Indonesian military said Australia, the United States, Germany, France, Russia, India and Turkey have also offered assistance. South Korea said it has also offered help.

Thank you for starting this thread, @LadyL.

It is so uplifting to hear of countries offering help to locate the submarine. Together, they may be able to make the best plan to get the crew out alive before Saturday.

In the below news article, there is mention of an "oil slick" spotted by air. Hoping that the naval vessels can identify the location using their sonar. This is so hopeful. JMO


Indonesian leader orders all-out effort to find submarine as oxygen runs low


"An aerial search found an oil spill near the submarine's dive location, and two navy vessels with sonar capability had been deployed to assist in the search, officials said.

The oil slick could indicate damage to the vessel or could be a signal from the crew, the navy said."

Submarine crew has less than 24 hours' worth of oxygen, rescuers focus on unidentified floating object

"The missing sub can safely operate in waters up to 500 metres deep, but authorities fear a loss of power could have seen the vessel sink to a much greater depth.

"If the object detected is the submarine, Navy authorities suspect the crew may have deliberately released its fuel load to allow it to float after the possible loss of power."

How terrifying would that be?

Very.
Almost worst nightmare come true.

 

[LadyL]

I really hope they can get to them in time. Those poor people must be so terrified.

Friday will be their last day of oxygen supply. Although to be honest, if the sub has already gone to 500 metres below, then that's almost likely to be beyond the 'crush limit' of the submarine.
They do have escape chutes on subs, so wonder why these weren't deployed at a shallower depth, so everyone could at least try to get out safely.

I did read yesterday that a sonar had detected them at approx. 100-150 metres. Dumping diesel then submerging further is not a great idea. If you escape from the chute, which propels you out, while down at 150 metres, you stand a chance your life can be saved and you can get to the surface. Sadly, 500 metres is too far down.

In my honest opinion, the submarine has had catastrophic failure, sank, and crushed at depth. It was built in 1977, and even though it has a refit in 2012, it's really too old for service.

Time running out for missing Indonesian submarine as U.S. joins search

"Search helicopters and more ships left Bali and a naval base in Java heading to the area where contact was lost with the 44-year-old KRI Nanggala-402 on Wednesday as it prepared to conduct a torpedo drill, with the head of the Indonesian submarine fleet aboard."

"If the submarine was still intact, officials said it would only have enough air to last until around dawn on Saturday."

"So far we haven't found it... but with the equipment available we should be able to find the location," Achmad Riad, a spokesman for the Indonesian military, told a news conference."

"An Indonesian air force pilot said six tonnes of equipment had been flown to a base to help with the search including underwater balloons to help lift a vessel."

Thanks for creating this thread. I have been following this story as well. I have always been fascinated with submarines. This sort of disaster would be the ultimate horror I think. I applaud the efforts being made by the Indonesians and other nations to help. Unfortunately, I think the chance these sailors are still alive is very slim. I really don't understand why some of these nations operate submarines like this. It is very expensive and you can't cut corners or this is what happens.

I've been following...hoping against hope for the survival of these men.

Right now it is in fact 3 am, 24 th April there ....

"We've only got until 0300 tomorrow [Saturday] so we're maximising all of our efforts today," said Indonesian military spokesman Achmad Riad.

what exactly happens at crush limit?

 

[PrairieWind]

what exactly happens at crush limit?

Once a submarine descends below its crush depth, the pressure of the sea becomes stronger than the hull of the submarine can withstand. The hull is crushed like a tin can. Or like the USS Scorpion, the back is shoved into the front like a collapsing telescope. Death would be nearly instantaneous for the crew.

man that's awful

this article says their oxygen may have already run out

just updated....
Here too re: O2 and the possibility of crush.

So very sad.
Reminds me of the one off Argentina, and of course the Kursk in the Barents Sea.

Indonesia submarine search feared to have failed as oxygen runs out

This is so terribly saddening.

It seemed a bit hopeful for a time there.

A submarine missing since Wednesday off the coast of Bali with 53 people on board has been lost, the Indonesian navy said on Saturday.

Parts of the submarine, along with debris including prayer mats, were found near where it went missing, the navy chief of staff said.

A scan detected the sub at a depth of 850m (2,800ft), well beyond its survivable limit.

"We have found several pieces and parts that are believed to be parts or components that are attached to the submarine that would not come out of the ship if there had not been pressure from outside or a crack in the torpedo launcher," said Navy Chief of Staff Yudo Margono.

Such tragic news.

It felt good to feel that bit of hope though and especially reading of various countries who offered help and showed up. That in itself is always so good to hear.
