The Thunder Horse PDQ is an oil platform that floats using ballast contained in underwater pontoons and has a total displacement of 130,000 metric tonnes. Owned by BP and ExxonMobil, the platform has been operating in the Gulf of Mexico since 2008 and can process and export 250,000 barrels of oil each day. In July 2005, the platform’s nearly 300-strong crew were evacuated due to the approach of Hurricane Dennis, which left the platform listing dangerously at 20 degrees.
