Emergency ballast blow

[SLK]

I think emergency ballast blow does not exist in uboats, but there is something equivalent? Lets say i am at bottom of ocean, nicely parked at 150m and no boyance. Water is getting in quickly than pumped. It is gameover?

Why would you think the Germans did not blow their ballasts under emergency conditions?

If you are sat at 150m and taking on water too fast then close the hatches of flooding compartments and make sure that you stop any leaks in the control or engine rooms. The emergency blow system is accessible by selecting an officer and right clicking the valves in the control room.

ah! just missed them! Thanks!

Normal surfacing uses about 1/3 of your sub's compressed air reserves. An emergency blow will use it all but is the only way to get the water out of the ballast tanks at that depth.
If you're still stuck and there's no other way, there's a final trick you can try if you're desperate:

After you emergency blow the tanks, turn on the diesel and electric compressors. This will force the air in the crew compartment into your ballast tanks. If you're lucky, you'll get buoyant again before everyone suffocates.

If you have rebreathers you can enter badly flooded spaces to close up leaks.

The pump works up to 200 m on a linear scale. At 150 m you have 25% pump ability.

Above 200m if you got the leaks closed you will eventually pump the water out, unless hit by more depth charges.

One of my tactics is to find a tactical coastline of 100 - 180 m depth so if needed can belly down and hope on eventual repairs.

If doing the sit on bottom be sure to switch on blue light, stop torpedo loading, turn off grycompass (though I use the mod that eliminates as a noise source as not significant in real life reports) and so on. Bottom does bounce sound so its hard for them to know where you are. Depth charges might be set shallower than you too.

I have... how to say... enjoyed... being in too shallow of water and taking screenshots of depth charges landing on the deck of my sub not yet detonating as they didnt reach their set depth. O_o

i'll try both's tricks. I do not like very much reloading saved games when i lose, feels cheating to me, and so far when i get hit, i eventually die all time.

I tried 3 aproaches so far when get pinged.

a) When get pinged i stop all and go to bottom.

b) Slow movement away from position, increase depth or go bottom.

c) Flank speed right on target, increase depth and when below enemy sharply turn 90º and slow down and change depth.

Oddly all work out more or less in open sea, but all fail when i am setting mines very close to their bases. Last time i had, i don't know, but about 20 warships above me. I dont understand how and if it is possible to do it without decoys. I am slower than warships, can't surface or i'll get trashed, they just sit over me till i get no air... and when they find me i get leaks both in electric motor compartment and in torpedos compartment. I can block water in control room, but ship is dead, valves don't work and half crew die suffocating in water or with injuries. And if i try to surface quickly before so much water gets in, their cannons destroy me in seconds even at night...

It seems or mission is too hard (3rd one setting mines near Cardiff iirc) or i am doing something awfully wrong.

PS: I am playing at max realism, just with 3rd person and damage control medium, max difficulties on both initial settings.
