5 years later, the cause...

Here is a good vid on how the deep water Horizon oil spill was caused.

It's a good watch.



Kind of makes you wonder how many other vulnerable rigs are out there.

Good informative vid....

Ya, so I wonder if BP is still on the hook for the failure, I mean they paid billions already.

The manufacturers of the BOP might have to claim some responsibility.

Yeah lets go drill for oil in 5000feet of water,, what could possibly go wrong? LMAO

I guess 5000ft is nothing when the deepwater horizon was capable of drilling in 10000ft of water. that was whole lot of crap that had to go wrong for that to happen. just hopefully nothing like this happens again.

Capable of doing it sure. Too bad It only takes one "accident" to do irreversible damage to the planet. Nuclear energy HAD a pretty good track record too....

Damb Duke.. Where were you 5 years ago.. This coulda been prevented!!

Not sure how dude? Some people want money way too badly for me to stop them

Thanks for posting.

Relying on a powered shutdown in the event of failure is ridiculous, shutdown circuits should be designed to fail closed or in the safe position on loss of signal.

 

[CUSO]

Well the vid did show that the wiring was faulty...

Thats why I kind of wonder if it was all of BP's responsibility...?>?>

Agreed the wiring was faulty, but the shutdown should have been active if there was a fault or inoperable part in the shutdown system. Im not sure who takes liability on that? Surely they must have function tests and be required to prove shutdowns periodically just like any other hazardous operation in industry. I guess it comes down to who owns the BOP and is responsible for its proper operation? When I have a contractor working on my lease it is my responsibility as a site supervisor (BP representative) to confirm that all calibrations and certifications are in place and current. This is generally satisfied with pre jobs and permitting. Undoubtedly there will be a lot of finger pointing on this one. Hopefully we learn something from this.

Every other safety device I know of is designed to fail in the safe position when power/communication is cut. For example all our gas valves at work are designed to automatically close if the lose air pressure. I'm actually amazed these BOP's were designed and signed off by engineers considering how easy it was for them to have the wiring mixed up. Even designed the way they were they should have been tested before being placed on the bottom of the fricken ocean

 

[vrscr43]

Obviously the emergency systems were not functioned checked on the surface, as circuits were wired incorrectly.
That's crazy, 5000 feet down and we forgot to function check the safety system.....

 

[cdnredneck_t3]

I am not a BOP expert, I work in downstream but did spend a year in upstream. It seems to me they are building the failsafe to allow redundant manual activation. If the shear were to engage because of a communication loss caused by something as simple as a bad connector that would cause more harm than good. I don't know how hard it would be to repair the well or if it would be a total loss.

What I am wondering about is why there would be enough clearance in the shear that if the drill stem was out of centre it only partially cut it. I would think that the shear would be designed that it could cut the drill pipe no matter what. I have seen videos of rigs taking a kick and it will push the drill pipe out of the well like spaghetti. It makes sense that the pipe might not be centred in the BOP.

There has to be some BOP experts on here to explain things a bit better.

5years already eh? Wow time flies

 

[Bogger]

I've had the privilege of working with and discussing this incident with one of the lead investigators for Transocean.

Was a tragedy and an environmental disaster but very interesting from an investigation point of view. less than 12 hours prior to the incident the crew was recognized by senior company officials for record safety performance.

 

[CUSO]

Apparently that pipe is 21" in diameter. that would be some massive shears...

 

[SUMMIT TREE]

Record safety = really efficient at hiding shi...er stuff that should be addressed but is expensive to fix
