Dramatic Photos Of SSV Deepwater HorizonSubmitted by indpr on Mon, 05/03/2010 - 20:58
"Gulf oil rigs have had an impeccable safety record for decades. Despite the fury of Hurricn Katrina, not one -- of thousand -- Gulf oill rigs caused an oil leak.
But one Gulf rig SSV Deepwater Horizon caught fire & exploded in April 2010.
SSV Deepwater Horizon was a fifth generation, RBS-8D design ultra-deepwater dynamic positioned column-stabilized semi-submersible drilling rig, which drills wells in the floor of the sea, while other types of rigs are used to produce oil from the completed wells. The rig was 396 feet (121 m) long and 256 feet (78 m) wide and according to Billy Nungesser, the president of Plaquemines Parish, Louisiana, was "one of the largest, deep water, off-shore drilling rigs." It could operate in waters up to 8,000 feet (2,400 m) deep, and had a maximum drill depth of 30,000 feet (9,100 m). The rig could accomodate up to 146 crew members. The semisubmersible rig was floated to the drilling location; it had pontoons and four columns that partially submerged when the rig was ballasted down to drilling air gap. The rig was not supported by the sea floor but its pontoons sat under the water.
SSV Deepwater Horizon worked on BP's Mississippi Canyon Block 252, referred to as the Macondo prospect. The rig was last located 50 miles (80 km) off the southeast coast of Louisiana. In October 2009 BP extended the contract for Deepwater Horizon by three years, to begin in September 2010. The lease contract was worth US$544M, a rate of US$496,800 per day. But in April 2010 there was about a new and unexpected overhead expense.
SSV Deepwater Horizon was in the final phases of drilling a well in which casing is cemented in place, reinforcing the well. This is a delicate process as there is the possibility of a blowout, the uncontrolled release of formation fluids from the well. On April 20, 2010, an explosion occurred on the rig and it caught fire.
On April 22 2010 at about 5 PM there was a rare & dramitic explosion... http://www.cargolaw.com/2010nightmare_deep_horizon.html
