What type of MODU was Deepwater Horizon?
Deepwater Horizon was a fifth-generation, RBS-8D design (i.e. model type), deepwater, dynamically positioned, column-stabilized, semi-submersible mobile offshore drilling unit, designed to drill subsea wells for oil exploration and production using an 18.75 in (476 mm), 15,000 psi (100,000 kPa) blowout preventer, and a …
Why was BP responsible for the oil spill?
In September 2014, a U.S. District Court judge ruled that BP was primarily responsible for the oil spill because of its gross negligence and reckless conduct. In April 2016, BP agreed to pay $20.8 billion in fines, the largest corporate settlement in United States history.

What could have been done to prevent Deepwater Horizon?
Safety upgrades are critical but could mean higher prices for oil and gas. A culture of tighter safety and more experienced regulators might have prevented the BP Deepwater Horizon leak. But equipment modifications and new technology will be needed to minimize the risk of such deepwater oil leaks.
What caused Macondo blowout?
“The failure of the rig crew to stop work on the Deepwater Horizon after encountering multiple hazards and warnings was a contributing cause of the Macondo blowout.” “BP’s cost or time saving decisions without considering contingencies and mitigation were contributing causes of the Macondo blowout.”
What is bladder effect in drilling?
of the technicians suggested that the 1,400 psi pressure on the drill pipe was being. caused by a phenomenon called the “bladder effect”— heavy mud in the riser was. exerting pressure on the annular preventer, which in turn transmitted pressure to the drill pipe.
What is a blowout on an oil rig?
An oil well blowout is an uncontrolled release of crude oil. Blowouts occur when pressure release systems fail. They can also occur if a spark or flame contacts the oil or for other reasons. Oil well blowouts cause death and catastrophic injuries to workers near the scene of a blowout.
What were the ethical issues in BP oil spill?
BP agreed to plead guilty today to charges of manslaughter, environmental crimes, and lying to Congress in connection with the 2010 Deepwater Horizon drilling rig explosion, which killed 11 workers and sent as much as 200 million gallons of oil into the Gulf of Mexico.
