Notes:

Thunder Horse PDQ is a BP plc and ExxonMobil joint venture semi-submersible oil platform on location over the Mississippi Canyon Thunder Horse oil field (Block 778/822), in deepwater Gulf of Mexico, 150 miles (240 km) southeast of New Orleans, moored in waters of 1,840 metres (6,040 ft). The "PDQ" identifies the platform as being a Production and oil Drilling facility with crew Quarters.

Thunder Horse PDQ is the largest offshore installation of its kind in the world. The vessel's hull is of GVA design. The hull was built by Daewoo Shipbuilding & Marine Engineering (DSME) in Okpo, South Korea, then loaded aboard the heavy lift ship MV Blue Marlin and transported to Kiewit Offshore Services in Ingleside, Texas where it was integrated with its topsides modules that were built in Morgan City, La.. The 15,813 nautical miles (29,286 km; 18,197 mi) journey around the Cape of Good Hope took nine weeks (63 days), from 23 July to 23 September 2004.

Thunder Horse PDQ was evacuated with the approach of Hurricane Dennis in July 2005. After the hurricane passed, the platform fell into a 20 degree list and was in danger of foundering.
