[QUOTE=Jamesbrown;193357]CM notes it as a guess. Seawater piping source requires cargo shifting damage. 0605 CM reports he doesn’t see cars broke free. Not conclusive, speculation. I think ventilation can be flooding there as well as engineeoom as noted… also might be worth exploring the ballast shifting to/from ramp tanks. In the back and forth maybe the engineering crew was distracted? The main prop casualty was ongoing. What if that hour of ballast shifting had unintended consequence to hold three?[/QUOTE]
No, not a guess on the C/M part. Here it is again:
CM 07:14:54.1 07:14:56.2
I think that water level’s rising captain.
CAPT 07:14:56.2 07:14:58.
(okay). do you know where it’s comin’ from?
CM 07:14:58.1 07:15:05.9
- (at) first the chief said something hit the fire main. got it ruptured. hard.
CAPT 07:15:05.6 07:15:07.3
um there’s no way to secure that?
CM 07:15:08.2 07:15:21.6
we don’t know if they’ve (seen/still have) any pressure on the fire main or not. don’t know where s’sea– between the sea suction and the hull or what uh but anything I say is a guess.
The “guess” is the answer to the question “is there any way to secure that?”
And yes, again, absoluely not conclusive. Not pure speculation however, call it an educated guess, an application of Occam’s razor, the simplest explanation that fits (most of?) the known facts.
I’ve been on RO/RO about 20 years, loose cargo can do a surprising amount of damage. When I saw that photo of the emergency fire main… Not much there to stop a heavy piece of fast moving cargo, steel gets torn up.
Of course it could be ballast vent pipes, hull breach?? But the C/E says the fire main was ruptured. That’s about as solid piece of information as it gets in this case. Any other source of the requred volume seems less likely.
And again, just my observations, YMMV.
