The exhaust is all water jacked so if you blow a fuel or oil line, there is no ignition heat source. Goal is no surfaces over 250F.
Now at this power level that's kinda hard to guarantee. We logged turbo cold side discharge at over 500F on the dyno. So ya do your best with what ya have.
The throttle blade as close to heads as possible is as Dave listed a Positive Air Shutoff. Most likely any non outside gas supplied runaway situation is gonna be fed by an oil feed line going to a turbo. So a guillotine or air knife setup won't work if you knock a hole in the pipes between and intake and turbo. Basically what happened to Mark when the charger wheel exploded. Got an oil/fuel supply, got air, she don't care a bit if ya cut the power or the lift pumps.
In a boat you have engines setting in a bathtub basically. So filling that area with Co2 or other inert gas displaces the oxygen. Besides fire suppression it will also kill a runaway. If ya notice in Mark's video, after he did that "graceful" exit, they spent another 30 seconds trying to kill that dragon. But it kept self feeding and reignited multiple times. These engines each have over 20qrts of oil and 300 gallons of fuel onboard. Ya get one shot to kill it quick, or may as well just jump overboard..
