The BP “Top Hat” should be lowered soon. This mini version of the 98 ton containment box that failed is the latest attempt to stop or stem the flow of oil leaking in to the Gulf of Mexico at a rate of 5,000 barrels a day. A “Junk Shot” is also in the works. The junk shot is a bunch of garbage to be shot into the pipe and secured in place with cement. The “Junk Shot” has a risk of pressure build up that could cause the pipe to burst into a more uncontrollable flow. Although given the current volume and length of time for this spill with no end in sight the idea of an even more “uncontrollable” spill seems oddly pedestrian at this point
BP spokesman Bill Salvin said the 2 ton box or “Top Hat” will be lowered to the seafloor, away from the plume, on Today. The goal is to have undersea robots position it over the gusher by Thursday. The box is on a vessel in the containment zone right now. Salvin said the box won’t be placed over the well right away so engineers can configure it properly and avoid the same kind of ice crystal buildup that stymied their first attempt at using a larger box.
Oil sheen levels from light to moderate from the Deepwater Horizon oil spill have been spotted as far west as the Timbalier Island sand and are expected to continue flowing west, forcing the state Department of Wildlife and Fisheries to extend its ban on recreational and commercial fishing in offshore waters of the state to Point au Fer island adjacent to Atchafalaya Bay. The ban extends to the beaches bordering those waters, said Wildlife and Fisheries Secretary Robert Barham, in a news release announcing the change.
Executives from BP and other companies involved in a deadly Gulf of Mexico offshore oil well blowout blamed each other in Washington this morning as troops and prison inmates rushed to shore up Louisiana’s coast against a huge oil slick.
The oil bosses were grilled by members of the Senate Energy Committee in the first of two days of hearings, with committee chairman Jeff Bingaman saying it appeared the April 20 explosion of the Deepwater Horizon rig was due to a “cascade of errors, technical, human and regulatory.”
