    Interview with rig survivor

    Also, this sounds like it could be a RIG problem, if there was some electrical box/component that was supposed to be explosion-proof wasn't, or failed. I assume venting gasses are a common occurence when a well is drilled. As such, any source of ignition must be eliminated eg arcing relay contacts, candlelit dinners, etc.

    • I worked in several of the largest gas plants in the world and can assure you that if they have a gas cloud that envelopes the rig, it will find an ignition source.

      If you look at pictures of the rig, before the fire, you will see 5 or 6 stacks that are from internal combustion engines that drive generators. I've seen gas cloud choke off engines, but many times they are the ingnition source.

      You cannot have the total rig be intrinsically safe when you have to produce power and have living quarters. Normally gas kickbacks are diverted to a flare system that is far from the rig deck.

      I have problems with the BOP not operating. This should not be overpowered since they use hydrolics to the close the valve and pressure from the wellhead if it exceeds the hydrolic pressure.

      For some reason, the BOP has not been actuated. I think Cameron has a problem here.

    • Apparently you didn't listen closely to the interview. The worker said the the gas enveloped the whole rig. So if we believe his statement, it sounds like it was a tragic accident.
