Deepwater Oil Spill - The LMRP Attempt BP is now saying that its Top Kill approach has failed, and it is moving on to LMRP. 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. .. What chances does this have? He announced Wednesday that BP preferred option in that instance would be to add a second BOP on top of the first.
