MORTON, Miss. — Jimmy Harrell, a supervisor on the Deepwater Horizon oil rig that exploded in the Gulf of Mexico in 2010, has died at age 65. Harrell, who worked for rig owner Transocean, died Monday, according to Wolf Funeral Home in Morton, Mississippi. He had battled cancer for a year. Eleven workers died in the explosion and 134 million gallons of oil spewed into the Gulf, fouling beaches from Louisiana to Florida, killing hundreds of thousands of marine animals and devastating the region’s tourist economy. Harrell was a key Transocean supervisor on the rig leased by BP. Investigations indicated Harrell had been unhappy with the oil giant’s plans for shutting down the rig. During a May 2010 government hearing he acknowledged disagreements but denied reports that there were heated debates.
