Indonesia: 'green water navy'

[STURM]

Hopefully she's located soon. This incident reinforces the vital need for navies with a sub capability to also have a rescue capability. Vietnam comes to mind; no idea if it has such a capability. .

Malaysia's Mega Bakti left Sepanggar this morning. She has participated in several international sub rescue exercises and is certified by the USN to operate its Rescue Diving and Recompression Systems and the Pressurized Rescue Module System.

Yes, with a fleet of 5 submarines, a submarine rescue ship is absolutely necessary, at least one.

No much news until now.

Kasal: Cadangan Oksigen KRI Nanggala-402 Sampai 72 Jam : Okezone Nasional

Dia berharap, operasi pencarian bisa segera mendapatkan KRI Nanggala 402. Sehingga cadangan oksigen masih ada dan semua kru bisa selamat.

The report above sounds that they expecting the submarine is not yet completely lost, but until now ive the feeling the navy doesnt know the exact position and condition of it. Hopefully the KRI Nanggala 402 is structural not damaged.

A support message from Australia.

Here is the full video of the press conference

Chief of Staff of the Navy goes deeper, it said they found an unusual magnetic signature though they did not confirm it to be the submarine. Still, hopefully this means that they have some leads as to where they're supposed to be looking.

On a side note, Prabowo mentioned something about a 25-year Master Plan at around 19:30 mark that is being finalized. It's probably nothing significant as it is a plan, but it's interesting nonetheless.

News reporting in Australia suggested the vessel was in 700m of water but the news have been known to get things wrong .... a lot. I hope that is not the case as it reduces the survival chances even if the boat is intact. I not sure if this vessel is equipped with a mating ring for a rescue system.

Hoping the boat is found soon and it is not too deep. Thoughts are with those on board an their families.

reporting in Australia suggested the vessel was in 700m of water but the news have been known to get things wrong .

That 700m news begin from local media quoting and interpretation from Navy chief talk yesterday evening. I watch his interview, and as far as I can see, he's only worries the Submarine can fall into that depth cause there's trench on that deep near the area of last contact.

As usual by media, some miss interprete and talk the Navy already found the Submarine in the depth from 500m to 700m. Those interpretation then takin over by International media.

That's why on latest press release TNI very careful not to give unconfirmed findings, as there's too much wild interpretation from online sources, enthusiasts forums, social media, and broadcast media.

Sailors on missing KRI Nanggala submarine have oxygen until Saturday - National - The Jakarta Post

The defence officials were speaking at a news conference a day after the 44-year-old submarine went missing while conducting a torpedo drill north of the island of Bali. The chief of staff said weather conditions for the search and rescue efforts were calm.

www.thejakartapost.com

They are now talking more on relative more 'confirmed' information like the the submarine action on last call check (as I put in my previous post), or the one I put now on oxygen reserve. If you see Indonesian Defense enthusiasts forums or social media, there's too much speculation based on weak information or simply imagination that sometimes being blown out even to media.

Officially they're still has not given any possition of stricken submarine yet. There's some hope on findings but nothing substantial yet.

 

[Sandhi Yudha]

The search for KRI Nanggala 402 continues.
TNI-AL plans to send 21 warships and 5 aircrafts in total to find the submarine.

Updates.
Even India has sent a submarine rescue ship. India’s Ministry of Defence stated that its Deep Submergence Rescue Vessel (DSRV) had been despatched on Thursday 22 April from Visakhapatnam Naval Base though it gave no time of arrival.

3 Submarine Rescue Ships Hunting for Missing Indonesian Submarine - USNI News

KULA LUMPUR — Search efforts on Thursday have yet to turn up any sign of the missing Indonesian attack submarine KRI Nanggala (402) and 53 personnel. Meanwhile, submarine rescue ships from three different countries are en route to the scene near Bali. India, Malaysia and Singapore have all...

No much development since yesterday.
A video from Kompas TV uploaded today describes the situation of yesterday. In the end of the video they try to give general information about the submarine, its just funny to see how the people who made this video have absolutely zero knowledge about the subject.

We hope for the best, but after all these days of no signs of KRI Nanggala 402 and the finding of the oil/fuel spot on the place of accident on the first day, are signs that we have to prepare for the worst.

I would like to give a shout out to @Ananda and @Sandhi Yudha for there regular updates during this crisis, much appreciate.
thanks guys

HMAS Ballarat & HMAS Sirius have been diverted to assist TNI-AL in their SAR efforts. HMAS Ballarat has en embarked MH-60R helo to aid the search.

It's unfortunate that virtually all foreign vessel will not be able to arrive to help within the 72 hour oxygen limit. Then again, as it stand it's very unlikely that the crew is still alive considering what we know so far.

The US is also sending P-8s as per the latest press conference

We can always live in hope. Never give up.

It's unfortunate that virtually all foreign vessel will not be able to arrive to help within the 72 hour oxygen limit.

Reports like this may be a translation from Bahasa issue. For most submarines (certainly for AIP and nuclear submarines), they carry oxygen candles — when burnt these produce oxygen without the need for electricity. Submarines however, need electricity to scrub out CO², H² and other toxins from the air. The battery will still discharge even while idle (i.e. byproduct accumulation of H²) and the risk of combustion is substantial. On atmospheric control, it's not just about O². Spare O² candles is one of variables to 72hrs.

Then again, as it stand it's very unlikely that the crew is still alive considering what we know so far.

The 72 hour thing may not be a hard limit. It is most likely to be related to air quality before too much H² and CO² build up — causing the crew not to think clearly.

The crew may not do well but there is still hope up to the 90 hour mark, if H², CO² and air quality is managed by the crew in anticipation of rescue — so obviously no cooking and other things that contribute to loss of air quality, without working scrubbers.

The issue is whether the submarine still has battery power to operate scrubbers; and how long was the sub-in-distress before their scrubbers stop working. Right now, TNI-AL has not declared the submarine as found — we really know too little to speculate.

Exactly...we almost know nothing, only that there was some oil on the place of disappearance.

But it seems that they found some "strong magnetic point" in that area.
"Menurutnya, ada satu titik magnet kuat yang akan dikejar sesuai petunjuk dari hasil pencarian yang diperoleh dari KRI Rimau."

KRI Pulau Rimau 724 is an old Project 89,2 (Kondor II class) minesweeper, i didn't expect that these old worn out ships are still capable for such tasks.

The Long Journey Of The Search For The KRI Nanggala-402 Submarine, Hoping For A Miracle

The search process for the KRI Nanggala-402 submarine which was declared missing boxes in northern Bali waters is still ongoing. Various ways have been done, though, not getting results.

MV Swift Rescue and KRI Rigel 933 are expected to arrive today, late in the afternoon or in the evening.

Her sonar would be useful in scanning the sea bed.

 

[Ananda]

Video from latest Press Conference from TNI. There's still no definite contact yet. However seems they're now focusing on magnetic contact that KRI Rimau found. They are hoping more assets with better sonar will come to the area. At this moment they're still hoping KRI Nanggala doing black out condition to reserve everything. However if that the condition, there's chances the underwater current can push the submarine away. For that they are also spreading the search area.

 

[Sandhi Yudha]

It seems that 5 persons from the Singapore Armed Forces are arrived in Indonesia and already on board the KRI dr. Soeharso 990. It is unclear if they will serve on the MV Swift Rescue, which is also on its way to the sea north of Pulau Bali, or if they will serve on other vessels.

Also HMAS Ballarat and HMAS Sirius are on their way from Australia.

These 5 are likely to be Bahasa speaking Singaporean naval liaison officers, including submariners, who are military experts on sub-rescue (with in-depth subject matter expertise).

They are there to support the TNI AL commander to fully use all the classified bag of tools and tricks for effective employment of dipping sonars on naval helicopters and the side-scan sonar and AUV carried on MV Swift Rescue — time is of essence and the RSN wants to make sure the integration with TNI AL’s search effort is seamless with all 3 sub-rescue boats arriving from India, Malaysia and Singapore.

 

[Arji]

American P-8 is joining the hunt tonight!

Here's hoping that the added ASW capability at play will manage to find Nanggala... who knows if the plane did amazing, maybe our generals will be impressed and results in wanting to procure one.

When you think about it, this whole thing is like conducting a joint ASW exercise between nations.

Minor correction. I believe that HMS Ships Ballarat and Sirius were exercising within the region and have been diverted, and rather than needing to spend days reaching the search area from Australia are already nearby

[STURM]

Hopefully someone more knowledgeable will correct me if I’m mistaken; am I correct in assuming that when it comes to detecting objects on the seabed; the sonars on MCMs are more suitable compared to ASW ones?
