Damaged Sub Fully Repaired then Sinks Like a Stone

[scrapser]

I guess this is yet another bug we all paid good money to UBISoft to enjoy. Is there a fix for it or is it one of the hardcoded bugs modders can't get to?

I had a beautifully executed attack on a Task Force ruined because of this. My sub took damage but I managed to sink a Fuso and cripple an Ise. After running under a thermal layer and letting the crew repair the damage, as soon as I adjusted depth...down she went.

[Quillan]

What do you mean by "adjusted depth"? If you've taken hull damage, it is never repaired in the field. So if you went deeper, it's quite possible you passed the new threshold of how much pressure the damaged sub can take, and imploded.

[Ducimus]

And what was your hull integrity, and did you use one of those super duper uber crew skills that repairs destroyed items?

Yes,any time I have taken hull damages,I am very careful on how deep I will go until I've been back to a base for proper repairs.

[scrapser]

When the DC encounter began I was at 120 feet and slowly sank to 140 from taking damage. The crew went to work and while fixing things the sub sank to 150 and I got the thermal layer message so I stayed there running a 1/3 until all repairs were complete. When they were done the hull meter read 66.

Once the destroyers backed off, I ordered periscope depth and as soon as I crossed the thermal layer, they started pinging and turned around towards me. So I ordered a depth of 140 and the sub just kept on diving. Even emergency surface was useless.

Usual repair items on a sub:

Not that great at 150 feet. Anyway, I believe you will slowly loose hit points on the sub the longer you stay submerged deep. If your hull is at 66% you are in big trouble. I recommend no more then 100 feet and run like hell. Forget silent running. Your number is up at the moment. Have the men keep repairing and flank speed with lots of twisting and turning. Good Luck!

[LukeFF]

Let's see here...66% of your hull integrity is gone, and you expect your sub to float like it would if it had no damage? Sorry, that's not the way things work. :rotfl:

[THE_MASK]

I have never had hull damage in SH4 . I dont get that close to destroyers . (apart from the time i ran into a task force surfaced in fog LOL )

[CaptainHaplo]

You didnt specify what type sub you had. Even with a gato you would be fubar'd at 66% - thats 2/3 hull damage. Given the game figures a gato is safe at say - 350 feet, 66% of your hull integrity is gone - meaning you have given up about 231 feet of max dept. That leaves you able to "safely" dive up to 119 feet. You went deeper than that. Anytime your deeper than your "safe depth", additional hull damage accrues - but never gets called out by your crew. It continues to accrue until you SURFACE - meaning that even if you come above your safe depth - the damage is still happening until you surface - which you didn't. So as you manuevered, your hull integrity continued to drop, and when you tried to duck under the layer, your sub finally "broke" under the strain - taking you down to crush. While it may at first appear that its a bug, its actually a decent (though not perfect) way to simulate the stress on your boat.

Hope this explanation helps you understand that what happened is simply because you choose to take your boat below what its damage level defined as safe. Had you never gone deeper than ~120 feet, you would have been ok, provided you could still lose the escorts.

Now....what hull meter, where? I seem to always not see it.

[CaptHawkeye]

The topic creator and Kongo's Deputy Damage Control Officer seem to have similarly bad habits. :)

[scrapser]

Well to answer the idea that I don't understand hull integrity, I guess what threw me was that I was at 150 with 66% hull damage with everything else repaired and was able to go to periscope depth. Just doing that should have halted any further accumulation of hull damage. When I increased depth the second time (140), the sub just kept on going. My thinking was I should still be able to go to the depth I had come from but not any deeper.

The boat is a Tambor class (Trout) to answer that question.

I restarted my last save and engaged the Task Force again. This time I was only able to sink one Ise and damage a second along with an escort carrier. I was successful in eluding all destroyers and now have a photo recon assignment to perform on Formosa (the Task Force encounter was at convoy college). The Task Force was huge by the way.

One question...if you keep sending status reports will you continue to get assignments even if you start getting low on fuel and need to head back to port?

[AVGWarhawk]

One question...if you keep sending status reports will you continue to get assignments even if you start getting low on fuel and need to head back to port?

Yes. If you blow it off because of fuel/torp issues it will not count against you. Skippers could call it a day when low on fuel or out of torps.

[Fincuan]

One question...if you keep sending status reports will you continue to get assignments even if you start getting low on fuel and need to head back to port?

No, you stop getting new assignments when your fuel goes below 10% or torpedoes below 25%(stock SH4). For example RSRDC ups these values quite a bit, since 10% of fuel won't obviously take you very far.

I had hull damage of 16% once and after the immediate "issues" were corrected, I took a look with the free camera to see what hull damage might look like since everything was being reported as fixed... except for the little note about hull damage... it didn't show up in the repair logs anywhere else.

turns out I had a hole in my sub from a lucky shot by the crew manning the deck gun of a merchant. A merchant! I was so disgusted that he would dare take a shot at me when all I had done was to surface for the purpose of finishing him off that I just ignored the sound of a shell striking my boat till after the battle. Wow, had I known I had a hole in my boat big enough to walk through...

Needless to say, I ran for home with my tail between my legs hoping that I could stay on the surface the whole way. I wasn't that lucky but I avoided contact with warships like the plague and never submerged below periscope depth. I felt fortunate to get home safely and since then I always check for deck guns on merchants before I surface to use my own deck gun. Those guys just don't play fair.

Anyway; if I had a big hole in my sub at just 16%, I wonder what scrapser's must have looked like at a whopping 66% - probably like a spaghetti sieve.

:huh:

Actually, at 150 feet the pressure on the hull could have been acting like a kind of compress. Pressure held things securely where they happened to be, but when you came to periscope depth; it could have relieved the pressure and allowed the plates to shift. When you went down the second time things just gave.

Nor sure that it is implemented in the game so far as the damage model goes; but at 150 ft, the pressure exerted on the hull of your boat would be about 500% that exerted at the surface, so such a scenario is very possible in the real world.

[CaptainHaplo]

Penta - the hull meter is only in 1.4 and above - so make sure your patched up! As for its location - go to the damage control screen and look to the left - there is a 3 digit hull damage counter there.

[Buffalo9]

It sounds like the duct tape just didn't hold very well, I prefer the black over the gray for wet conditions.

[Penta]

Patched to 1.4, dun see it?

[gimpy117]

don't rip him, mine does this on the surface

[spec24]

My Hull Damage reads 031 (I assume 31% damaged). Everything else has been repaired, engines, etc. But the sub won't move. I'm on the surface and there's nothing to be done. Is this right? Should my sub not be able to move?

[JoeCorrado]

Here is an example of what 23% hull damage looks like. Notice that everything that can be done by the crew has been done and nothing shows as being "damaged" other than those few little numbers that say hull damage: 023 percent. Then take a look at what that means, a couple of really big holes:

And about that bulkhead that was repaired... they meant THIS one. Looking straight in through what used to be my bow.

http://webpages.charter.net/joecorrado1/Image2.jpg

I was able to return to base, but I held my breath every minute and I never, ever tested the integrity of my hull by diving beyond periscope depth. Survival, escape and evasion became THE one and only mission.

[Penta]

Okay, I'm confused. I never see this hull damage number...Anywhere, and I've looked.

Is it modded in?

Could someone post a screenie highlighting it for me?

[spec24]

Hey Penta. It's not modded in, it's in the upper right of your damage control room.

Can anyone answer if everything else is repaired, and all you have is some hull damage (I'm afloat, no flooding) , should I be able to move? Or I guess I should ask is it possible that I can't move.... or is this a bug? (see my previous post). I would really like to return to port and continue my campaign. This is really bugging me as there is no way to call for help or break out the oars and start paddling :)

Hey JoeCorrado - how do you get the camera to get inside your ship and stuff? I've seen a lot of screenshots that I can't come close to because the camera won't move any closer. Is there a mod? I've looked but haven't found one.

1. In the screen shots above, I had the hull damage but I was also leaking fuel. Barely made it back to base.

You might check to see if your peopellars are still with you. LOL

One other thing to look at is if you have left your crew at battle sdtations for too long- they will pass out at their stations and you can ask for engines till the cows come home and they won't respond. If so, just secure from general quarters and they will respond again.

2. Looking from outside in, just use the free camera.

[spec24]

I'll try those suggestions Joe, thanks.

Don't you have your camera inside your sub in that one pic? In my Silent Hunter I can only get my camera so close to my sub or other ships and then the camera stops. It won't let me get in real close. I've seen lots of screenshots where people are in a lot closer than I am :( I hate that my camera is limited.

[CaptainHaplo]

Spec, regarding damaged engines - the way the game works with damage is that while the damage control screens show 4 engines - you really only have 2 as technically handled by the game. Because of this, if your engines are damaged beyond a certain point, even "repaired" they won't run. This makes you dead in the water. At that point its a question of reloading a save to due how the damage model works, or saving and editing the save to properly "fix" your engines.
