ORIGINAL: InvisibleBlack -FR- Have they determined what actually happened yet? I've seen a lot of speculation but very few facts on what triggered this disaster. Apparently, there was a massive "kick" in gas pressure coming up the standpipe. The cement cap or plug that was supposed to prevent sudden gas flows from coming up the pipe failed, allowing the gas to come all the way up the pipe and vent into the working areas of the platform. A spark ignited the gas, causing an explosion and then a fire. The fire caused the power systems to fail, which then caused all the other onboard safety systems to fail. The rig burned until it sank, and when it sank it broke the standpipe attaching it to the ocean floor. The blowout preventer (BPO), which is a hydraulic ram designed to shear off the pipe at the ocean floor and seal it shut as a last resort, then failed to work properly. It operates by remote control, and while they were apparently able to get it to slam shut, it would not stay closed. As of a few hours ago, BP is reporting that they have managed to get it working to some degree, but not enough to completely shut off the flow of oil. They do feel that they have slowed the leak significantly, but they can not yet determine how much, or whether it will stay closed. That's the inside information I'm getting from people in the petroleum industry on another board. Some of the exact details may not be entirely accurate, but from what the oil people down in the Gulf are saying, that's the broad outline, and I'm getting it from people i know are connected down there and whom I consider to be pretty reliable. Several of them are actually working on the repair effort. Edit: OK, after first saying this this morning - quote:
MOBILE, Ala. (WALA) - Oil spill update: BP official Jeff Childs says the company has been able to deploy a ram that clamps around the drill pipe at the bottom of the Gulf of Mexico. Childs says that maneuver has slowed the flow of oil in and around the pipe. BP is now saying - quote:
CLARIFICATION ON GULF OF MEXICO OIL SPILL FLOW BP would like to clarify that, contrary to some media reports, the actions it has taken to date on the blow out preventer have not resulted in any observed reduction in the rate of flow of oil from the MC252 well. So I don't know what to believe. That last press release is about 15 minutes old. They've either slowed the rate of the leak, or they haven't. One or the other. Maybe they'll get their story straight sometime later today.
