by the time the rescue vessel arrived, am afraid its been too late.

I hope that i wrong.
With this news come around the quality of other 4 subs are questionable since Cakra is as old as Nanggala meanwhile the other is KW 3 subs.

Submarine has freshly dived, if the hull is intact and all compartments are up, then they have at least a week or even more controlling air quality.

They shouldn't have mentioned about the oil spill there are at least 10 other reasons i can list right now for the cause of oil spill.
Since they haven't reported and acoustical anomaly, indicating an explosion or implosion -bubble rise, it means the chances are still high for them to be safe.

im actually waiting for that conclusion , if the nearby sosus or other underwater sensor pickup any hydroacoustic anomaly , if there wasn't any , there's still a chance the whole hull still intact .

Depend on depth you can even eject your pee or even poo overboard. However, if one have enough air pressure to spill fuel overboard why not using it to blow the ballast tanks

section 3, page 18:

3.10. ABILITY OF THE DISSUB TO SIGNAL HER POSITION
a. The crew of a DISSUB may be able to indicate her position by one or more of the following methods:
1. Releasing one or two indicator buoys.
2. Firing Submarine Launched One Way Transmission (SLOT) buoys which transmit on VHF JEZEBEL Channels 25, 27, 29 or 31.
3. Firing an expendable communications buoy (ECB) or SEPIRB, which will transmit a SARBE DF beacon.
4. Firing yellow or white smoke candles or red or green grenades. The smoke candles may have fluorescent dye containers attached, which produce patches of green dye in the water, and may also carry a message
5. Transmitting her name in voice plain language and/or in SST mode on the UWT.
6. Transmitting on sonar, echo sounder, or by using emergency location beacons.
7. Hull tapping.
8. Releasing fuel or lubricating oil.
9. Switching on navigation or other underwater lights

Wait wait, how could the crew operate a sumbarine without electricity ?
Above diagnostic mention the sub is in totally blackout condition

meanwhile the other is KW 3 subs.

PENGHINAAN! The rest are KW2

all compartments are up

In this case, that is the part where I cross my fingers the most

australian LR5 can be air transport within 48 hour. can we somehow provide a vessel large enough and bring those equipment to the site?

its better to have a backup to the singapore one

And using those some kind of substance to remove co2.

Repair?

The "blackout" was referring to lost of comm. Furthermore, in the event of total lost of power the crew can still operate the essential systems using hydraulic

Any vessel with an A-frame compatible/capable of handling the DSRV also with an adequate dynamic positioning ability can theoretically use it.
Should be looking for nearby Offshore supply, cable laying, ocean-bottom working vessels. I am sure they are notified for a possible help.

this reminds me of Das Boote movie

 

[R4duga]

is our new changbogo have a standarized hatch where DSRV can connect/mating with the submarine hull incase something like this happened ? because the latest info i got , nanggala doesn't have such capability .

48 hour? Its faster to wait for MV swift rescue, she is already moving at top speed 12 kt.

Both Australian ship is still at their base I think, should we contact British SPAG?

The Royal Navy's Submarine Parachute Assistance Group (SPAG) is a team who provide a rescue support capability to submarine sinking incidents worldwide, available at short notice.

we can use their expertise.

 

[NEKO]

the sub is in totally blackout condition

Its still a speculation.

SPAG only use when the crew already abandon ship using Submarine Escape Immersion Equipment and needed rescue, better to call their NSRV

offcourse it has, submarine post 1970s are generally equipped with all-compatible escape hatch,

 

[R4duga]

i got this from FB , not trying to speculating or some sort , but i was hoping we're facing this scenario instead the grim one .

better to have backup than relying solely on swift rescue, it also mean we can use both dsrv if needed
