Feb. 2013 - BP, operator of the Thunder Horse field, issued an order to FMC Technologies for additional equipment intended to bolster water injection at the field. The subsea infrastructure at Thunder Horse lies in 6,300 feet of water. FMC will supply two manifolds and associated control equipment along with pipeline end terminations, flowline and jumper kits and umbilical termination assemblies. Deliverables are scheduled to begin shipping in the first half of 2013.

Apr. 2010 - BP will begin shutting down around 50% of wells feeding into the Thunder Horse oil and gas platform at a cost of $500 million due to lost production and direct construction costs, the Financial Times reported. It is expected the shutdown will last around 60 days while BP implements a permanent repair system to minimize delays on the project. Situated in a water depth of 6,050 feet (1,844 meters), the Thunder Horse oil and gas field is located on Mississippi Canyon Blocks 776, 777 and 778, about 150 miles (241 kilometers) southeast of New Orleans, La. Thunder Horse is operated by BP, which holds a 75% interest; ExxonMobil holds the remaining 25% interest in the field.

Nov. 2009 - Transocean's Discoverer Enterprise drillship is on location at Thunder Horse North to perform completion operations on Mississippi Canyon Block 775. Thunder Horse North successfully commenced production in early 2009. BP operates this field with a 75% working interest while ExxonMobil holds the remaining 25%.

Sep. 2009 - Aker Solutions signed a contract with BP to perform subsea construction activities at the operator's Atlantis and Thunder Horse fields in the Gulf of Mexico. The scope of work includes installation of subsea hardware including manifolds, pipeline-end manifolds, jumpers, flying leads and related equipment. The project is expected to start in Q4 2009 and will be executed by Aker Solutions' vessels, the BOA Sub C and BOA Deep C. The Atlantis field covers Green Canyon Blocks 698, 588, 700, 742, 743 and 744 while Thunder Horse covers Mississippi Canyon Blocks 777, 778 and 822 in water depths of more than 5,999 feet (1,829 meters).

Apr. 2009 - The BP-operated Thunder Horse platform, located on Block MC 778, ramped up its oil and gas output, producing roughly 300,000 boepd in March, up from 200,000 boepd in February. The ramp-up makes BP the largest producer in the GOM, with 400,000 boe in net production a day. Discovered in 1999, the platform was originally scheduled to become operational in 2005, but didn't commence production until June 2008.

Mar. 2009 - Production at the BP-operated Thunder Horse platform has reached 260,000 bopd. BP's head of E&P said that the northern section of the Thunder Horse field has come on-stream. Additionally, the production capacity on the Thunder Horse platform is now 280,000 bopd, which is 30,000 more than originally announced.

Dec. 2008 - BP has successfully started production from the third and fourth wells at the Thunder Horse field with production now in excess of 200,000 boepd.

BP's Chief Executive Tony Hayward said at a news conference after the company reported second-quarter earnings that he expected Thunder Horse North to start production in the second half of 2009. The long-delayed field, 150 miles southwest of New Orleans, will produce a maximum of 250,000 barrels per day of oil and 200 million cubic feet per day of natural gas when it reaches peak production.

Feb. 2007 - The start of production at the company's Thunder Horse field in the Gulf of Mexico was postponed from 2005 to 2008, after the offshore platform was damaged due to a technical fault as a hurricane approached.

Sep. 2006 - Following a series of tests carried out over the past four months that revealed metallurgical failure in components of the subsea system, BP plans to retrieve and rebuild all the sea-bed production equipment from its Thunder Horse field in the deepwater Gulf of Mexico. BP said the problem became evident when it conducted pre-commissioning tests by pumping water through the system to establish system integrity. The equipment passed all the normal industry standard tests and regulatory requirements.

Aug. 2006 - The latest delay in the start-up schedule for BP PLC's (BP) giant Thunder Horse project was caused by cracked welds at an underwater structure, an analyst said Friday.

Jul. 2005 - The joint effort by BP, SMIT, the US Coast Guard and US Department of Interior's Minerals Management Service continues today to respond to the Thunder Horse platform incident in Mississippi Canyon Block 778 approximately 150 miles southeast of New Orleans. The recovery team made significant progress in the last 24-hours. The platform is stable, the trim is normal, freeboard is normal and displacement is normal. Concern for safety and the environment remain top priorities. Operations to-date have resulted in one minor injury. There have been no spills. The weather at the scene of the recovery effort remains calm. BP and its lead contractor SMIT continue activities to make the platform sea-worthy and storm-safe as a precaution against changes in weather conditions resulting from the progress of Hurricane Emily into the western Gulf of Mexico.
