Basically the ocean can crush us into a tin can.

I cannot imagine the pain!!

The Ocean is one deadly place. That explains why my mum never allowed me to do spear fishing and scuba diving. Her biggest fear was me and my brother getting lost at sea.
Then you miss a lot of fun.
Try basic recreational scuba first, or if it's too expensive, go with snorkling first and gradually took recreational open water scuba training & certification. Only then you should play with spear fishing. Plenty of great fish for beach side BBQ here in Indonesia because you could also pick any additional ingredients that grew naturally near the beach


It is reported an object was detected at 50-100 meters. Earlier it was reported an MCM vessel detected a magnetic anomaly hovering above the bottom. Could be related to each other.
I trust any Mexican comic that is full of drugs, violence, and rapping scene more than I trust anything that came from The Guardian

Maintenance? It could be caused by external factors such as getting heavily entangled in a fishing net etc.
Getting tangled in a fishing net doesn't make water to pour in into the people tube.

And if you or any of you here actually paying any attention at all to the official statement (of which most of you here doesn't seem so) its actually giving plenty of hints as to what maybe the cause of the accident.

Another dumb Indon journalist who doesn't even know how to take video using his not so smartphone

Gw kira kapal keruk...

I believe this is earlier picture of the DSRV (enroute by ship, so will take a week and be too late for alive-crew SAR). This DSRV I believe needs full ship support...even if it can be air-transported.

The one being airlifted now is another model I think, and hopefully it has more independent capability or this can quickly be done with existing ships in area (with various personel to handle this also flying there).

This whole incident got me into reading more about DSRVs around the world, quite a lot I had no idea about.

The second one might be intended for Malaysian SRS Mega Bakti? I am not sure if their submarine rescue vessel is equipped with a SRV so they might use an airlifted one.
Mega Bakti also has an A frame which allows deployment of SRV and other rescue items (actually the ship herself resembles Swift Rescue a lot)

To be honest ... I've allready prepared for the worst here . While i haven't lost the hope as yet ... Thing are starting to look grim and desperate

Let's all pray for the best result..

It is not a countdown, officials should have never disclosed exact numbers to the public.

Yup, it was both unprofessional and unnecessary, but now damage has been done unfortunately on that front.

They should well know how this is picked up by any media (local and world). I see all these headlines in big world news about 72 hours etc....and all implication and insinuation from that too....and I get very disappointed at how this was not needed at all, as you have explained before w.r.t what the terms can even mean in first place.

Honestly feel higher-up people should just know lot better w.r.t active/ongoing SAR situation to begin with....and how world media feeds on particular soundbite + their extrapolation/interpretation.

RCN (retd.) buddy of mine (ex-submariner himself) also had same approach of immediate defeatism (he knows a few particulars about 209 class etc)...but I'm like buddy, we cannot have this kind of approach to it...there is plenty of time later for it....but for now we have to do our best, have maximum hope+morale and assume lives are to be saved till proven/known otherwise. But in any case, he is not a public figure like INA admiral is....that was quite disappointing statement. All such things can be analysed afterwards.

Expecting local media publish articles:
"About to run out of oxygen, these are the tricks submarine crew do to save it"

Or something like that
 

this is crunch

yep totally agree with you, that was unnecessary aproach to inform to the public, but then, the navy spokesman only speaks what's left of it, he is not totally wrong, when he said "The Submarine might only had 72 hour oxygen left", we as people with higher understanding of some stuff than other people, we are not consuming raw-information without processing it first,
ofcourse we re-asking the statement itself, was it real? was it seems to logic? we doing cross research of it, then we might we might take conclusion of it wether the statement is true

but you must know, here in indonesia, most of local media and its own journalist, they rarely well-researched the topic, and rarely cross-check everything, they loved to play over dramatic, overreact, and over stupid, as one official source would said something, the media process that into its own serial drama, so much spice and salt they put add into it, so the primary information is covered with that dumb naration,

and whats more irony is, (most of) the local people itself who consume any information from the media seriously, i mean, what the media said they recognize it as "the true fact", and stupidly they act the same as the media did, no cross check, and no research, its funny tho, watching those people arguing and speculating over what is happening without proper fact,

I just did a calculation of my own (using dimensions of boat and some biophysics), and understand where they are coming from w.r.t 3 days and 72 hours.

Numbers/assumptions I used and the results:

Pressure hull (using diameter of 6m and an approx 50+m length of cylinder and minimum packing factor)

Volume = 1500 m^3 (somewhere between 1400 and 1600, but this is small +/- sensitivity in the end)

CO2 starting concentration = 400 ppm

CO2 Toxic range assumed around 40,000+ ppm *

CO2 density = 2 kg/m^3

Air density = 1.2 kg/m^3

Total air = 1800 kg

Humans convert/displace O2 and exhale about 1kg/day of CO2 (but could be less**)

In the end it boils down to time it takes for 60 m^3 CO2 (4% i.e 40,000 ppm) or about 120 kg to occur.

120 kg of CO2 at 1kg/day times 53 crew comes to around 3 days (the starting air volume could indeed be larger like 1700 m^3 etc and there can be give with some of the other numbers like CO2 exhale per day).

However * and ** can buy some more time, in fact a lot more time given it is observed (in couple MSDS and OSHA I looked up), many healthy adult humans can tolerate/survive up to 80,000 ppm CO2 or even a bit more than that.....and by breathing exercise/training, the metabolism can be slowed sufficiently for producing as little CO2 (even compared to regular sedentary) quite drastically.

The 80,000 ppm tolerance by itself buys twice the time for example. I am unsure how low CO2 production can be reduced with training (it would buy further time as well), maybe someone can find out.

Thus it is not surprising @anmdt referred to latter already a number of times.

There might be a few other factors I am missing, but just to give ballpark of where the 3 day number comes from...and also why it shouldn't be applied so prematurely.

These two (*/**) factors will be crucial in the end if the submarine is intact.

Let us continue to hope and pray for the best.

3-star generals, Pangkogabwilhan?
To anyone who may wonder what the abbreviation stands for, it's "Panglima Komando Gabungan Wilayah Pertahanan" or "Commander of the Joint Command of the Defense Area"

I'm using Google translate to transliterate the words, btw. So it might not be totally accurate.

Wait, my eyes are blurry, its either a 3-star general or a colonel (three jasmine buds)

Still no update about object with big magnetism in depth of 50-100 m although Rigel already on site, I think that was miss lead again. 😔
