However an analysts' review "painted a more equivocal picture" with Transocean rigs being disproportionately responsible for safety related incidents in the Gulf and industry surveys reporting concerns over falling quality and performance.  One of the decisions that met with tough questions was that BP refuted the findings of advanced modelling software that had ascertained over three times as many centralizers were needed on the rig. While displacing the mud with seawater, reservoir fluids rising up the casing should have been detected by water inflow and mud outflow monitoring before arrival of hydrocarbons at the rig floor, but no reasonably accurate outflow versus inflow observations were made. Hot oil is hotter than steam. An oil tanker was damaged in the Red Sea near Saudi Arabia after a mine exploded on Wednesday, the Associated Press reported, citing the tankerâs operator and a maritime security company. The survey found that "many workers entered fake data to try to circumvent the system.  A House Energy and Commerce Committee statement in June 2010 noted that in a number of cases leading up to the explosion, BP appears to have chosen riskier procedures to save time or money, sometimes against the advice of its staff or contractors. After uncontrolled arrival of oil and gas at the rig floor, the blind-shear rams in the BOP stack failed to close due to the presence of off-center drill pipe. Also the Department of Justice was still at the time investigating whether BP was "grossly negligent" in the spill. , The explosion was followed by a fire that engulfed the platform. Micro-explosion of droplets of W/O emulsified fuels plays an important role in energy saving and emission reduction [1,2,14]. Food coloring is water-based so it mixes with the water. These incidents were considered typical for a Gulf platform and were not connected to the April 2010 explosion and spill. Tony and McGeek trace one lead, which appears to reach a dead end, but which leaves egg on McGoo's face; Gibbs and the other Abby suspect that the target was not the platform but rather the dead victim. , The blowout preventer was damaged in a previously unreported accident in late March.

Oil and water do not mix. Club BP has been a finalist for a national safety award from the MMS for the past two years.  The Coast Guard stated on April 22 that they received word of the sinking at approximately 10:21 am.  Coast Guard Rear Admiral Mary Landry expressed cautious optimism of zero environmental impact, stating that no oil was emanating from either the wellhead or the broken pipes and that oil spilled from the explosion and sinking was being contained. Jim Ingram stated that "on the second [thud], we knew something was wrong. Transocean, responding to the report, blamed "BP's fatally flawed well design. , The BP wellhead had been fitted with a blowout preventer (BOP), but it was not fitted with remote-control or acoustically activated triggers for use in case of an emergency requiring a platform to be evacuated. Then stir to combine. 4. The explosion caused serious injuries to threecrewmembers and damage to the thermal oil heater cover and its surrounding equipment andfittings.  The rig's mechanic stated that the well had been experiencing problems for months, and that the drill repeatedly kicked due to resistance from high gas pressure. From Die Hard to The Muppet Christmas Carol, these festive movies and holiday TV episodes are guaranteed to boost your holiday spirit.

The platform commenced drilling in February 2010 at a water depth of approximately 5,000 feet (1,500 m). Fines would be apportioned commensurate with the degree of negligence of the parties, measured against the number of barrels of oil spilled. Witnesses reported hearing a "huge" blast at the factory in Church Manorway, Erith, south-east London, at about 9:00 BST A fire broke out afterwards, and firefighters remain at the scene. , An April draft of a BP memo warned that the cementing of the casing was unlikely to be successful. In the 3 years 2005 to 2007, Transocean was the owner of 30% of oil rigs active in the Gulf, and 33% of incidents that triggered a Minerals Management Service (MMS) investigation were on Transocean rigs. , A total of 115 people were evacuated.

Most of the hole over this portion of casing had a 9.875 inch diameter. The slick appears as a silvery-gray patch in the center of the image. The unexpectedly high pressure and subsequent lower-than-specified mud flow led to problems 2 and 3.  Two remotely operated underwater vehicles (ROVs) were sent down in an attempt to cap the well but were unsuccessful.

Survivors described the incident as a sudden explosion that gave them less than five minutes to escape as the alarm went off. BP's most recent estimate at the time was that the spill would cost $41.3 billion. history. Deepwater Horizon oil spill, largest marine oil spill in history, caused by an April 20, 2010, explosion on the Deepwater Horizon oil rigâlocated in the Gulf of Mexico, approximately 41 miles (66 km) off the coast of Louisianaâand its subsequent sinking on April 22. In March 2008, the mineral rights to drill for oil on the Macondâ¦ Drill pipe was run to 8,367 ft, and was thought to be ready for mud displacement. However, in the 3 years from 2008 to February 15, 2010, it owned 42% of rigs but was responsible for 73% of incidents. , The fire aboard the Deepwater Horizon reportedly started at 9:56 p.m. CDT on April 20.

Fail-safe on seabed wellhead was unable to close. (29 Oct 2013).  According to the Wall Street Journal online: In 2008 and 2009, the surveys ranked Transocean last among deep-water drillers for "job quality" and second to last in 'overall satisfaction'. Valves to prevent cement backflow did not close.  On April 23, the Coast Guard called off the search for the 11 missing persons, concluding that "reasonable expectations of survival" had passed. The oil firm alleged that failed safety systems and irresponsible behaviour of contractors had led to the explosion, including claims that Halliburton "negligently" failed to use cement-modelling software OptiCem properly to analyze safe well requirements.
