Check out this other thread.

Much of what you are looking for is on this one.

The writer clearly hyped up the scenario. The turbines would have shut down on overspeed upon injesting raw gas, usually set at 63 to 65 hz. Light bulbs exploding? High voltage would have been the only thing to cause that. Once again, over voltage relays would have prevented that. Computers blowing up? Naw, didn’t happen.

Yeah, but it SOUNDS good! Like one of those Jurriasic Park movies!!

Been there done that offshore for 30 yrs.

Hey, listen, mister. You may have worked offshore oil rigs, but I've seen movies with my own two eyes!

Fascinating info from you and others here on what happens on these off-shore rigs. Thanks.

"cement containing nitrogen "

I always wondered if the industry went back to this after the failed experiments of the 80's (on shore).

Back then, they wanted to be able to save money on cement and instead, covered the entire rig in cement when the nitrogen expanded.

To me back then, porous cement for the final string of a high pressure well did not seem to be a good idea.

Right. I apologize for not prefacing what I cut-n-pasted from an email from my father who received it as the following. My dad (retired Exxon) still has a ton of contacts in the business.

No doubt it's all Bush' fault!

Or is that old saw becoming a bit threadbare by now??

That could very well be PSYCHO-FREEP, but since I wasn’t on the rig when it exploded (like you apparently were) nor do I have access to the evidence you seem to possess that proves “grave human error”, nor did I witness and document the “lack of safety equipment installed”, I am not in a position to express a definitive opinion on these specific matters like you are so comfortable doing.

At the very least your remarks are quite revealing about your interesting thought processes...thanks for sharing.

Great choice of user name for this particular set of comments by the way...

“They (BP) still failed to have a DDV (Down Hole Deployment Valve) installed in the intermediate casing string.”

Surely it is much better to have a Down Hole Deployment Valve than not, but after the catastrophic failure of all the other safety measures, including the failure of the blowout preventer, I am wondering the odds that the DDV would have worked. Let me ask you a question about this from an engineering point of view: what kind of high pressure would the DDV be typically rated to, as opposed to, what are the highest pressures typically encountered from the gas and oil?

I was just wondering. That’s why I asked. Thanks.

Good post and thanks for not being one of those boneheads that believe it was an act of sabotage.

I have never been on a rig that was lost, but I have been on rigs where the mud was not weighted correctly and it got a little scarry.

The bottom line is that someone at BP or one of the subs screwed up and whomever that was and BP needs to pay up Big Time.

To those that died, to those who were hurt, to those who are now out of work, to the fishermen, to those who have lost income and to clean up the Gulf, the beaches and the wetlands.

And yes people, because these people screwed up, we will not see any expansion in offshore driling.

Estimates of “how high it could go?” in the popular media - especially when they start talking of “what happens if the riser pipe breaks?” and all these other what-if’s?

I’ve seen some press quoting people inside government worrying about potential flows as high as 50K BPD.

Which is one hell of a lot of flow.

I’m wondering where they’re getting these numbers.

Thank you.

I bailed out of that thread when the conspiracy theories got thick and missed all the real info that followed.

Thank you. I appreciate the information and your sharing of the source. Lots of information floating around the internet and it helps to identify the better sources.

Cheers.

I wonder if that plug turned loose and that’s what’s in the BOP and why it doesn’t work.

If it turned loose with pretty much nothing but salt water over it, that plug would be like an artillery shell coming out of that 7”.

My pleasure. On a side note, I did work for a number of years doodlebugging, first for GSI, then for Teledyne Exploration after college (mainly GOM, North Sea, and a dreadful 6 months in Gambia/Senegal).

I see the Junk Media's disinformation campaign has been very successful. The oil is no where near the coast and it is no where near doing the sort of damage people seem to think it is doing.

CNN interview with Mississippi Gov Barbour

BLITZER: How worried should the folks in Mississippi be right now about the beautiful coastline along the Gulf of Mexico?

BARBOUR: Well, we need to be prepared. My view of this is when you pray for the best, prepare for the worst. But a lot of people are assuming that this is going to be catastrophic, and that is not a safe assumption.

Right now, there's no oil within 50 miles of the Mississippi. Eighty percent of the oil slick, as it's called and appropriately -- 80 percent is literally just sheen or film right on top of -- on top of the water. That is not toxic. It's not particularly damaging.

I mean, we don't want it to come ashore in Mississippi, but it's manageable. It's a manageable problem. Our people on the coast are getting ready.

And I do think a lot of people in the country are being led to believe that this is already some gigantic catastrophe. Well, that's not the case and we're going it try to keep it from ever being the case.

Yep. And it could it could well account for the loud THUD those on the rig reportedly heard just prior to the explosion(s).
