Hull Integrity down to such and such percent!!!

I've always wondered (voyager and DS9 are both notorius for this....) During battle, as the ship takes damage and sparks are flying all over, you hear Tuvok, Nog or Reed yell out: "Hull integrity down to __ %!!" What does this mean exactly? If my hull intergrity drops to say 40%, does that mean my ship is physically full of holes? or is it something to do with the molecular structure of my hull being only 40% of what it was before whatever damged me? How would you gauge Hull Integrity in real-time besides basically knowing my hull is damaged and where the damage is? how does that translate to a percentage in real time?

It means the ship is about to fall apart and everyone aboard is going to die.

Re: Hull Integrity down to such and such percent!!!

Here are actual possibilities as opposed to being full of holes. Either the sensors measure the strength of the hull and hull integrity is the percentage of that hull strength, or it is related to the structural integrity field strength, or perhaps both somehow.

Re: Hull Integrity down to such and such percent!!!

I take it as a shorthand for saying that, in its current state, the ship is estimated (by computer simulations) to be able to take about, say, 40% of the beatings it was able to withstand before the start of the battle (be it for weakened structures, actual holes in the ship, or a damaged integrity field).

Re: Hull Integrity down to such and such percent!!!

It can also mean that it is under some sort of transient stress. The hull is likely made of material (like steel) that can rebound easily and will NOT fatigue. Unlike aluminum that will eventually break from on and off force being applied to it.

Re: Hull Integrity down to such and such percent!!!

Unfortunately I'm not sure of the names of the instruments, but aren't there instruments in the 21st century that can be used to determine if there is abnormal stress on any part of a structure such as a building or bridge? Could that--combined with a measure of the structural integrity field--be in use?

It's a plot device used to 'raise the stakes' in an already tense situation

Why didnt they take the Wing Commander 3 road. Give your ships some armour and when torpedoes blow it all away you start taking some critical damage

They did that with the Defiant with her ablative armor.

Re: Hull Integrity down to such and such percent!!!

Since sometimes they indicate hull breaches, even though structural integrity still might be in the 60's, I bet that once it reaches 0 you have total space-frame/SIF failure.

But basically it's just somewhere to go once you say 'shields have failed'.
I prefer "SHIELDS COLLAPSING!" ala Scotty, but that's just not how the 24th Century shows did it.

Bonus: Take a shot every time the word "signature" is used on ENT.

Re: Hull Integrity down to such and such percent!!!

It could well be that "hull integrity" actually refers solely to the strength of the structural integrity fields, with 100% indicating full fields and 0% merely the physical strength of the hull itself, which as such may be negligible.

That way, integrity can go down to 40% under heavy fire yet quickly be restored to 85% when the enemy veers off and be back to 100% without the repair efforts of hundreds of welders - and without the need to show any of this in the form of visible external damage to the ship.

Heck, they're actually 20th century technology. Strain gauges.

The hull is only able to withstand 40% of the stress it was able to in peak condition. Problem is, such a hull would collapse long before reaching 0%...

Re: Hull Integrity down to such and such percent!!!

...Which is why the idea that all these percentage points are "extra", afforded by the structural integrity fields, and that zero percent corresponds to the passive integrity of the hull rather than to total disintegration, is rather helpful.

Re: Hull Integrity down to such and such percent!!!

Yeah, but I never understodd what the "structural integrity field" actually is.

Is it so some sort of energy field that reinforces the Hull? That's quite similar to shields, isn't it?

Hence why I chose to interpret it as a measure of the Hull's resistance itself in that post.
