    even if an explosive atmosphere had been created on the drill floor , all electrical equipment in the class 1 zone there should not have been able to ignite it. The IEC is in the proceess of creating ratings for mechanical equipment placed in hazardous areas so it can be certified as not being an ignition source.

    there is a lot more to this incident than just the BOP not activating.

    So what they have at the momment is total BOP failed as well cemment plugs didnt hold plus float & shoe failed or the last casing shoe cemment job failed. plus you still have all the well montering fuk ups that some one should of picked up on.
    What a cock up.

    It looks to me that there has been a catalogue of errors rather than just one. Correct me if I am wrong here but is it not the responsibility of the Client (BP) to ensure that there is a (SSW) Safe System of Work in place at all times, this System of Work should/must be followed by all contractors, sub contractors and anyone coming to the platform to carry out any work or maintainence.

    There has been a catastrophic failure somewhere in the system, this has lead to a very serious loss of life. I have no doubt that BP has Procedures in place for all Drilling Operations. The focus of attention will be that were these procedures being followed by the Drilling Company?

    There is still a long way to get to the root of this problem plus there are other factors which will need to be looked at concerning missing personnel.

    At the end of the day BP is the Client and will therefore be responsible.
    However there are others in this equation Contractor and sub contractors that will be looking very nervously at their companies positions in the grand scheme of things.
    Rarely do these events ever be for one reason..
    There is normally a build up of unsafe working operations before a major incident or event.

    One thing for sure the investigation and stopping the leak are two different issues. My money would be on stopping the leak first. And then a thorough investigation when all the facts are available.

    yes - but that is more likely on a land rig.

    that previous report said they were removing/ had removed the mud and were replacing/ had replaced it with seawater. the event must have been noticed in the mud tanks , either flow or gas detectors.

    Why more likely on a land rig ?
    Yes thats the whole problem no one noticed the gain probably by the time they did it shot up through the rig floor and ignited. I have seen mud shoot from the rig floor many a time and I can tell you it takes seconds to blow every thing out the table and hit the crown.
    Still doent explain the BOP failure but I would doubt the whole truth will ever come out.

    Does anybody have a link that describes the chain of events that led to this in layman's language?

    My son has worked on the gas and oil rigs around the UK off shore , and the health and safety is so tight it is nearly impossible to carry out the work , he is an Electrical/ Refrigeration Eng.

    I dont get your point, and doesnt really matter once you have lost control of a well you are stuffed no matter what distance you are from the Bop.

    Yes thats the case in most moden operations but there are still many shit operators on contractors that are willing to risk peoples lives to save a few hours and dollars.

    Ignition source is most likely the exhaust stacks from the 6 V-18 Warsilia's. One single spark coming out of just one of those stacks would be enough to set the gas off. I saw a live video shot from a camera in the Derrick on the Horizon before the fireball went up and it was the biggest cloud of gas I've ever seen.

    What a cock up.
    Below 4,500 ft with hydrates flowing thru the stack, it becomes frozen and unable to close the rams. That and the MUX cables and hydraulic lines were probably incnerated straight away thus making any closure of the stack impossible. That rig didn't have an Acoustic capabiity - remote closing. Anyhow, it was more than likely frozen...

    You seem to be a lawyer for the defense.

    Both pods failed ?? Couldn't close either hydril ??

    Hard to beleve that it came up through suspension plugs.

    a land rig is going to continue to sit on top of the well head and have the gas and liquids pouring though it.

    on the semi sub I would expect it only to have the initial flow until the drill string broke/cracked/deformed.

    It was a Cameron Stack and they were flowing thru the Divertors when it blew. You obviously don't want to close the Divertor lines so...the jury is still out.

    They just showed a live shot on television of an ROV (remote operated vehicle) attempting to do something to the stack which is covered in ice. As they say in China: "Rots a Ruck"!

    Most important to understand about this latest attack by North Korea against its South Korean enemy is that under the existing “laws of war” it was a permissible action as they remain in a state of war against each other due to South Korea’s refusal to sign the 1953 Armistice ending the Korean War.

    In this case there was no fluid hitting the crown or even the Block/Top Drive. After that cloud of gas ignited it looked like a firebomb went off on the floor.

    I would have never suspected that oil rigs were such an interesting topic, even if I don't understand 90% of the technical terms

    quite beautiful machinery at the end,

    Butterfly you and I are never going to be bosom buddies!!
    However I think that this very serious incident has nothing to do with North Korea. The reason I say this is that would they (North Korea) take a chance on an all out conflict between the USA/ South Korea.

    In todays present climate China is attempting to build bridges with the West. Including the USA and South Korea both in business and economic terms.

    I think the North Koreans are capable of sinking a vessel belonging to the South Korean military.
    However I am not so sure that the Chinese military would support them 100% for this aggression.

    There are oil rigs and then there are Dynamic Positioned Cyber Oil Rigs. In this case, the Horizon was a 6th generation semi-submersible capable in drillng in water depths of up to 8K feet without mooring lines - all positioning off satellites and beacons on the seabed.

    One thing that has not been mentioned thus far is the fact although the Horizon is DP (dynamic positioned) it was using soft-line mooring on this particular hole. Why that was done? It would have made it easier to get off the well if it was not moored...
