- This report focuses on the following critical questions:
• How did reservoir fluids reach the rig floor?
◦ How and why did reservoir fluids enter the well?
◦ What actions did the drill crew take?
• Why did the blowout preventer (BOP) not stop the flow of reservoir fluids?
• How did reservoir fluids ignite?
◦ What occurred after the reservoir fluids reached the rig?
◦ How did personnel onboard evacuate the rig?
I was on the investigation team. Seeing the animation makes me remember all the hours we worked on this video.
What was your conclusion?
Thank you for sharing your experience as part of the investigation team. It's understandable that watching the animation would bring back memories of the extensive work you put into the video. The investigation process must have been challenging, but your efforts have contributed to understanding the incident better.
BP is a piece of crap, they spent three months trying to figure out how they could get oil from that well. I've spent 10 years in the oil and gas industry so I've seen somethings. They could have capped that within a day and stop the flow of oil. That being said, don't they test the BP's t0 make sure they work in the event of a blowout?
The problem was that BP aimed for profit and did not allow emergency disconnection (EDS) at the time of the blow out, this decision made. Another CAMERON BOP issue is not secure.
The best BOP is the one from HYDRIL that has man-mort technology.
You raise an important point about the decision-making process and the role of profit in the Deepwater Horizon incident. It seems that the lack of emergency disconnection (EDS) and issues with the CAMERON BOP contributed to the severity of the blowout. These factors highlight the need for prioritizing safety over financial considerations in such situations
would like to know how/why the rig sank exactly!
The entire thing exploded. It was a semi submersible oil rig, it was a boat basically.
. ~Uncontrolled explosion due to a faulty BOP!.
The sinking of the Deepwater Horizon rig was the result of a blowout and subsequent explosion on April 20, 2010. The blowout caused a fire that eventually led to the rig's sinking.
This was so fucking preventable,Even after the failure of their systems!!
It is lamentable that the Deepwater Horizon disaster was preventable, even after the failure of the rig's systems. Transocean, the company that owned the rig, released an internal investigation report on the incident.

It shouldn’t be up to the staff onboard to stop this situation,I mean to a point normal required procedures yes,But the BOP is a flawed design!!And 3 months to close off the spill?!That should’ve happened immediately after the fire was put out!!!I mean with all that preparation it’s disgusting how long it took to not only prevent this catastrophic failure,But also to stop the leakage afterwards!!!If you’re going to put an environmental risk in place your containment efforts should be thought out eliminating any chance of failure as well as minimizing the effects of said failure!!
You express frustration with the flawed design of the blowout preventer (BOP) and the delayed response to the spill. It's concerning that it took three months to close off the spill and that the containment efforts were not efficient. The impact of failures in preventing and mitigating such incidents should indeed be minimized, and steps should be taken to ensure the effectiveness of containment measures.
Now i feel like if the crew knew what was going on they could have killed the engines and maybe it wouldn't have been so severe but everything happened so fast they had no time to react in that manner given they were following standard procedures to contain the well in the heat of the moment
Those engines were diesel. Once they got the new fuel source there was no shutting them down. They were in runaway
@dakotamurray3552 definitely. I meant if they could have seen what was gonna happen and snapped to it they could have shut them off before but who would have known gas was coming their way? Scary situation all together
I've been following these investigation and testimonies through countless sessions now and only get more confused each time? Statistics don't seem to matter to these people......in this video the BOP weighs 300 tons? I've heard 400 and 500 tons also....if we can't get the weight of this device stabilized how are we going to find anything out about what happened? Another major misunderstanding is the Riser? in this video it is mentioned the 'drill pipe' is 5 3/4 inches diameter? All they show going through BOP is the drill pipe? Is that right??? Other videos I have watched stated that the rig is connected to the BOP by a 20 inch riser? What is correct here? Are you telling me that only the drill pipe is holding the rig? is that correct? This all creates confusion as to how the BOP shears the riser.... is it shearing a 5 3/4 inch pipe or is it shearing a 20 inch pipe??? Why is it so difficult to describe this system? I can't understand how such confusion can lead to any correct results of an investigation.
Furthermore this video shows the bending of the drill pipe was due to the rig pulling the pipe? In other videos it says that the pipe was bent due to 'effective compression'.........which is it? How did that pipe get bent? If the ram cut the pipe why didn't the rig just float away? Answers please!
@Jay Watson Well Mr. Watson I guess it's all just 'elementary' huh? Very good explanation, thorough, you have to be more than just an observer here, perhaps a oil rig worker or engineer? Whatever I thank you for the detail of your explanation. I think the BOP needs a lot more work in design to be reliable but has potential. It amazes me how the small crew making the decisions did not have more corporate support in the decision process - it may have avoid the accident?
Rig is swimming on water afaik.
but I'm not sure how it stays at some position. Probably they have lots of engines to stabilise its position or just rely on drill pipe which is not secure that much as you pointed
The only confusion is yours. The systems you refer to are used on thousands and thousands of offshore and land drilling rigs around the world. There is no confusion about how these work. The reporting on this accident is done by a lot of different people that don't understand the industry or the systems being reported on. The people reporting on this and making videos like this are not experts in oil and gas drilling so obviously they can't explain everything perfectly so the average person is going to immediately understand the complicated systems that make up an offshore drilling rig.
In this video it clearly states after the engines on the rig died, electrical power was lost and the dynamic positioning system stopped working. Offshore rigs use several different systems to stay on location. This rig was in ultra deep water so it's kept in position by computers using gps controlling azimuthal turbines. The drilling pipe holds the drill bit and bottom hole assembly and transmits force from the rig floor to spin the drill pipe, it also transports the drilling mud being pumped by the rigs mud pumps. The riser just connects the rig to the bops on the bottom of the ocean. On shore rigs don't have risers the bops is installed at ground level and the rig floor is directly above the bops.
The pipe was bent by effective compression, weakened by the flow of formation fluids and then pulled apart by the rig moving due to failure of the dynamic positioning system which stopped functioning after power was lost.
Of course the drill pipe doesn't hold the rig in position that's just totally foolish.
@@richardnailhistorical3445 I guess you should redesign bops. Obviously you know better than the thousands of different engineers etc that have designed and worked in bops over the last 100 years.
Blow outs happen in seconds and the rig crew has established procedures which are practiced often, I don't about offshore but in Canada rig crews have numerous bop drills every 2 weeks rotation they work.
They have to react within seconds or every time there was a kick it would end up a blow out and rigs would be burning down with people dying on a regular basis. There is absolutely definitely no time to involve people from the office before the bops are operated and the well shut in. Once the well is shut in they involve management in the decisions to kill the well. But I assure you there's no time to do anything but react in a blow out situation. Which is why there is well established procedures in place that are practiced often. Being involved in kick/blow out is very intense, stressful, scary situation. The deep water horizon was a horrible disgusting event. It should not have happened. I believe there was a lot more involved than what they are admitting. BP was extremely complacent, careless, lazy and down right criminal in their numerous mistakes. The profits these oil companies bring in is just disgusting. They should have bankrupted that company in making them pay for damages and clean up.
But like so many other problems in the world today it's just a symptom of the real problem. Which is the super rich and corporations that have controlled the government and done what they want for far far too long. They look at the 99% as livestock for them to use and destroy for their profit. They believe the world to be far too overpopulate. Don't care about the damage to the planet because they want billions of us to die off.
Seems like the design of the BOP and blind shear rams is a little flawed... Nobody has yet to explain why there was so much space inside the BOP to allow the pipe to malform, move around and mis-align to the point of making the shear ineffective... I'm not convinced... The most telling thing is the amount of erosion on the steel components... They probably never got the actual reading of pressure that came up the stack because there weren't any gauges that went that high... I think they drilled into something that had never been drilled into before... and they learned the hard way NEVER to drill into something like that ever again...
I study this stuff and this conclusion does not convince me too
In other places they say lack of enough "spacers" between the riser and the drill pipe meant that there wasn't enough room for the cement to fill all the tiny gaps in the length of the riser and pipe. So in the case of the cement, there wasn't any room for the cement to get between the pipe and the riser, while in the BOP, there was so much room that the pipe could bend out of the way of the shear blades. Still haven't found anyone who will comment on whether a 1400 psi bladder effect was even possible.
You have reservations about the design of the BOP and the effectiveness of the blind shear rams. The space inside the BOP and the pipe's ability to misalign and deform seem to have compromised the shearing capability. Additionally, erosion on the steel components raises questions about pressure readings and drilling into unknown territories. These concerns highlight the need for improved design and thorough understanding of the drilling environment to prevent similar incidents in the future.
ahhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

hmm.... I guess it wasn't the "bladdah... eeefect." after all...
6) It seems that the situation depicted in the video didn't turn out as expected. The "bladdah... eeefect" mentioned might have been a predicted outcome that didn't occur. Sometimes, in complex operations like drilling, unexpected events or factors can influence the outcome.
1000 vids about such stuff,but ALL in fucking english!
NOT A FUCKING SINGLE VIDEO ABOUT THIS FUCKING KIND OF FUCKING TECHNICS IN FUCKING GERMAN LANGUAGE!!!!!!!!!!!
Well....it happened in USA territory...
There may be numerous videos available on the topic you mentioned, but it seems that they are predominantly in English. It seems that you are frustrated by the lack of videos about a specific technical topic in the German language. I understand your frustration, but unfortunately, I cannot change the availability of videos in a particular language.

I'm sorry, but I'm unable to make sense of the comment you provided. It appears to be a random combination of words.
