Interior secretary to issue new drilling ban
Nearly everything you could ever want (except a kill):
dell, Again, you provide us with valuable information. THank you , so much
see latest info that the BOP hydraulic was already leaking more than weeks before the accident.
That explains why when they pressed the EDS button nothing happened… No hydraulics no means to shear…
All TOI and BP personnel on board new about the hydraulic leaks but they did not pull the stack to repair it!!!
They just changes from yellow pod to the blue pod, but as per the witness the BOP continued to leak even after they changed pods…

Probably, but even after the ROV hooked up directly and applied 2x the pressure, 3000psi, one of the rams would still not budge. Plus, who knows what it was trying to shear? Drill pipe AND casing? Finally, and this is purely speculation, there’s a possibility that had the BOPs closed off completely, the possibly compromised casing would have communicated with the strata and worked it’s way up to the sea floor. (Not that any of this has any bearing on whether or not the BOPs should have worked properly…)
Someone earlier wanted to ask alcor a question. See post #1251 here:
Can’t keep a good (Johnny-one-note) down! :-))

Wow Pribas, great deduction.
How many stacks you been on? How many rigs?
I wouldn’t expect you to know BOP hydraulic circuits, but its sad when people who work onboard do not.
A leak on a surface accumulator does not affect the dead man.
The dead man did not fire, because all the criteria were not met to fire it.

The rov didn’t have the volume to shift the regulator, had nothing to do with pressure.
That’s why the went down the second time with an accumulator, and it fired.
Everyone here thinks there an expert on BOP’s and who here has ever worked on one? Seen one? Seen a p&id of one? an actual photo of one?
Speak up with real experience. Otherwise stop speculating about a device you know nothing about.
There is no great mystery of failure here. No drama.
The only failure on the DWH, and their management ashore… was people.
The culture of snobbery, if not of safety, seems to run very deep. And he’s not Amoco: http://www.nytimes.com/2010/06/23/business/23dudley.html?scp=1&sq=dudley&st=cse
Some info on EDS, Autoshear and Deadman systems.

Bnhpr, unfortunately, the idea that speculation isn’t going to happen or have to happen is not going to change things. Speculation of some type needs to occur & occur very soon. If we have to wait for all the evidence to come forward in a contorlled manner, everyone in the world who depends on deepwater fossil fuels for income & energy will starve to death. It is time to face the fact that the relief well may not work any better than the top kill which didn’t for whatever reason work any better than the BOP. This means we have to make a decision to continue to search & dig for fossil fuels or watch prices rise beyond belief for energy. This means people like you which have had two months to make your case for what happened & why based upon known occurances, events, & testimony of people involved are missing your opportunity to contribute to the betterment of your industry. This means if people like you don’t opine with knowledge assistingothers to look in the right cracks for the truth then others who may want to put misinformation out enforcing their viewpoint will control the story & in turn control the direction of the future of this industry. Now you can sit back & criticize from your little perch above & then bitch about how all the wrong decisions were made by those involved in decision making, or you can put your two cents in, be an active part of the investigation & have a positive influence for the future of your industry.
I know this. Anyone depending on a set of BOPs to be the primary well control device is a fool. Anyone operating form the perspective that they can be careless & wreckless in every aspect of well control & barrier design & testing of barriers & then say the BOP or the well head will save us is a fool. Nothing will prevent what occured on 4/20/10 without the other aspects of safety & well control working together. It is becoming painfully obvious to me that TO’s management was as negligent as BP management. It seems as though they were putting costs ahead of safety as well. If this company wants to continue working in the United States, they had better rethink their position on safety & where their priorities stand. They are not in the same position as BP in the sense that they have not shown a pattern of safety abuses that BP has shown in the past. Given the testimony of Mark Hafle & the internal BP email talking about the poor cement job from the Atlanits, I am very concerned about an undergroung blowout occurance in the future from an already existing BP project.
I am all for using common sense in allowing other operators to safely continue drilling in the GOM, but we have a repeat chronic offender who is convinced that we are all stupid & that they did nothing wrong in the face of all the evidence. These people need not only to have their company taken from them, they desperately need incarseration as part of the rehabilitation process.
I can’t make this stuff up: http://blogs.wsj.com/source/2010/06/22/bp-magazine-discovers-a-bright-side-to-the-oil-spill/?mod=e2tw
The comments are worth skimming too.

That ‘looks’ right from the code I’ve seen, on the DW ships it is a GE PLC programmed by Silver Tech but i don’t have the code, that was one of the few GE’s i wasn’t involved in commissioning but helped troubleshoot it with the ET’s on other DW ships than the DWH. It is no ‘fluke’ that the Sub Sea man was asked MANY times if he understood the ‘logic’ of the stack and alwase would throw the ET’s under the ‘skate’ about it when asked. MUCH MORE will be said about this sa they get into what happend with the stack.
Check the video streams - top hat if off, action going on now!
Bnhpr looks like you have not done the required home work of what is happening and what has already been ventilated on this case.
the testimony of the rig personnel that survived is that when they hit the EDS & nothing happened on the BOP stack due to the fact that it was without hydraulic pressure. The EDS button was pressed by the subsea super before they left the rig, and even before the captain requested him to do so. The BOP panel had already a red light on it’s top area. Again see the testimony that has been given.
So a ROV tech guys sees a leak on a BOP pod fitting (with the ROV inspecting the Bop) and you talk about a leak on a surface accumulator…
Looks like you are the one with a lack of understanding of how a BOP works…

The containment cap on top of the Macondo blowout in the US Gulf has been pulled the the Transocean drillship Discoverer Enterprise has moved off location after a remotely operated vehicle (ROV) hit the cap.
The ROV closed one of the vents on the cap that regulate the amount of oil flowing up through the system and keep pressure from building, Coast Guard Admiral Thad Allen said.
The closure caused pressure to build in the system and caused gas to begin bubbling up through the line that is used to inject warm water around the line bringing oil to the surface.
The water keeps natural gas hydrate chrystals from forming in the line and clogging it.
Discoverer Enterprise moved off after the bubbles were spotted due to safety concerns.
Allen said he hopes to rehook the system this afternoon and the Q4000 platform continues to flare off about 10,000 barrels per day.
What looks like a pipe sticking up can be seen from skandi rov1, where that come from?
surely they have been catching samples, wonder what the sand cut is?
[QUOTE=View 2 a ?;37567]What looks like a pipe sticking up can be seen from skandi rov1, where that come from?[/QUOTE]
Probably the other “half” of the one or two pieces of pipe that were shown in the video of the cut end of the riser (what ever they are eventually determined to be) wouldn’t ya think?
