9 but publicized June 12 outlines new plans to increase capacity including addition of the Discoverer Clear Leader which will process 5-10,000 barrels of oil a day using the Kill Line on the blow out preventer through the manifold used in the Top Kill operation. Oil will be stored and offloaded and gas will be flared. The plan will provide capacity of handling 38,000 barrels/day by mid-July. In addition to the previously announced permanent riser to the Toisa Pisces and Loch Rannoch, BP announces plan for a second permanent riser to the Helix Producer with oil offloaded to a yet to be determined tanker. This will increase capacity to 40 to 50,000 barrels a day by mid-July. In addition the Discoverer Enterprise will remain providing 15,000-18,000 in reserve capacity. Watson responds in a letter dated June 11 but made public June 12 that the plan does not deal with increased flow estimates and does not offer enough redundancies. 5,000 pound tank from the Deepwater Horizon washes ashore in Panama City Beach, Florida. June 13 BP begins installation of sensors into the containment cap to measure the oil flow. Obama is scheduling to address the nation on June 15 following his fourth trip to the Gulf since the spill and the day before he will meet with BP executives. June 14 Henry Waxman sends Hayward a letter outlining BP shoddy practices in April leading up to the blowout. Suttles in a letter to Watson says a new Floating Production Storage and Offloading from South America will be brought to the site in about 4 weeks. It can handle 25,000 barrels and will provide backup for the Toisa Pisces and the Helix Producer. Two Lightering oil tankers will come from Europe (bringing the total number to three). of 6 inch coflexip had been acquired and will provide redundancy in the event of a subsea hose failure or loss. The changes will increase capacity to 60,000 to 80,000 barrels a day by mid July. Suttles however warns "Several hundred people are working in a confined space with live hydrocarbons on up to four vessels...This is significantly beyond both BP and industry practice" and adds that with so many vessels working in a relatively small area there's a risk of a "major surface accident."
