Actually this was all stated by the Chief Electronics Tech, who was on
the vessel at the time of the blowout. Most BIG Gensets do not have Air
Dams if they are 4 Stroke Engines Those are common on the Detroit
Diesel 2 Strokes, but they (Detroit Diesels) don't even come close to
the size of gensets onboard this vessel. LubeOil Runaway is a Two Stroke
Diesel Phenomenon, 4 Strokes don't do that.

Any outside source of fuel may cause a diesel engine to run away.
Actually not unusual on drilling rigs, they get a little gas bubble
and the engines speed up and then go back to normal. Detroit Diesels
were famous for it, a blower seal would fail allowing lube oil into
the induction system and away they go. Whether the rack is open of
closed has no effect if the engine is running on an alternate source
of fuel.

I don't believe anyone ever intimated that the "motors" failed. The
diesel engines blew up. No engines, no generators, no power.

No, what was said to happen was that the kick blew enough gas into the
engine room and mud pump room to make the diesel engines run away and
then burst. An instant loss of generators and electrical power.
Possible that started the fire and possible it was something on the
rig floor banged against something else and made a spark.

I believe that the BOP had two different systems, electrical and
hydraulic as well as several redundant systems. BOP's are normally
tested periodically and a record is kept of the results on most rigs.
And even if the rig crew were so slack that they didn't test the
system - which is pretty far fetched as the drilling crew is well
aware of what is going to happen to them (and it did) if they need the
BOPs and they don't work - the MMS makes frequent visits to the rig
and BOP checks are one of the things that they check for.
In addition all of the larger offshore rigs and probably most of the
small ones have real time video all over the place and certainly on
the rig floor and the home office does watch what is going on out
there. and calls up on the satellite phone to bitch about things.
Since, as far as I know, oil is flowing out the riser which means that
the BOP's probably didn't close, or only partially closed, and my
guess is that if they ever get the well killed that they will cut the
BOP stack off and recover it as if the BOP's themselves failed then
both the oil company and the drilling company will go after the people
that made the BOP's.

That's why I mentioned that I've seen many engines that have air-intake
shut-offs. When running on lube oil, tripping the fuel rack does
nothing, just as you say. But tripping the air intake shut starves the
engine of air and it would stall.

Well perhaps the statement 'blew every light bulb and motor on the
Ship...' was misleading then. It sounded to me like the poster was
claiming the motors 'blew' in some way.

One article said that BP and the rig owner were arguing about the
diagrams and that some alteration had been made to the BOP. When they
connected to the BOP to activate the ram that would kill the flow, they
only activated a test ram that had little effect on the flow. Both
sides argue that the change shouldn't have been made without authorization.
http://www.mcclatchydc.com/2010/05/12/94067/oil-spill-bp-had-wrong-diagram.html
Another pointed out that at the extreme pressures involved, bits of rock
may have eroded the BOP plugs as they started to shut off the well,
causing them to leak.
http://www.theoildrum.com/pdf/theoildrum_6421.pdf
But I haven't found any article that blames the BOP failure on a loss of
power as 'you@shadow.org' claimed. The articles I found agree with you
in stating that they have redundant power to operate (and both manual
and automatic shutoffs). Even after the initial explosion/fire, the
attempts to activate it directly from the sea floor failed. So the
scenario of losing the diesel generators prevented the BOP from
operating seems to be pure fiction on 'you@shadow.org' part.
