A few comments from the press: Top Kill Fails To Plug Oil Spill, BP Now To Try LMRP Cap BP said preparations have been made for the possible deployment of the lower marine riser package (LMRP) cap containment system, which would be complex because of the depth of the oil leak. Deployment would first involve removing the damaged riser from the top of the failed BOP to leave a cleanly-cut pipe at the top of the BOP's LMRP. The cap, a containment device with a sealing grommet, will be connected to a riser from the Discoverer Enterprise drillship, 5,000 feet above on the surface, and placed over the LMRP with the intention of capturing most of the oil and gas flowing from the well. Mr Suttles said it should capture "most of the oil" and was expected to last at least four days but "we cannot guarantee success at this time." This is a diagram that Heading Out posted a few days ago, of the LMRP. The Lower Marine Riser Package (LMRP) option According to Upstream Online: If the top kill does not work, the UK supermajor plans to cut off the riser from the lower marine riser package (LMRP) and attach another to collect the flow. The device would be coupled to a flex joint above the LMRP with a sealing grommet to keep water out of the flow and control gas hydrate formation. The cap also has valves to inject methanol or hot water into the production stream. BP has already lowered the LMRP cap to the seafloor so it could be deployed immediately after a failed top kill. Installing the cap would take about four days, Suttles said, and it could be in place early next week. The LMRP cap would allow BP to capture as much of the flow from the well as possible while it works on other options to kill the well, he said. He announced Wednesday that BP preferred option in that instance would be to add a second BOP on top of the first.theoildrum.com == 4. If you have come here to vet your plan to kill the well, understand that you will be queried on whether or not you have read the other 10 previous comment threads and all the myriad plans that have already been run by the kind folks in this room; if you have actually read all 10 comment threads and still think your plan has legs, well, then maybe yours really is the one that will save the Gulf of Mexico. This is not to say that well considered questions about current attempts and modifications to those attempts are not welcome; they are. But try to place them in context and in what's actually going on, as opposed to your MacGyver dream solution where you have a 10 megaton bomb, an ice pick, and Commander Spock at your side
