Factbox: U.S. Energy Disasters in 2010
HOUSTON (Reuters) - Energy production and distribution in the United States can be a dangerous pursuit, in spite of strict safety regulations for oil, gas and coal producers and processors.
Following is a look at energy-related disasters that have rocked the United States in the course of 2010, including the deadly and environmentally destructive oil spill at BP's Macondo prospect in the Gulf of Mexico, which began in April.
Sept 2 - An offshore production rig operated by Mariner Energy in the Gulf of Mexico had a fire, forcing the immediate evacuation of 13 personnel and a major rescue response -- currently in progress -- from the U.S. Coast Guard, which said it identified an oil sheen at the site. The company had recently been producing around 1,400 barrels of crude and 9.2 million cubic feet per day of natural gas at the site.
July 26 - The Enbridge 6B crude pipeline, capacity 190,000 barrels per day, ruptured in Michigan and spilled more than 19,000 barrels into local waterways in one of the largest U.S. pipeline disasters ever. The pipeline remains closed and has affected some refinery operations across the U.S. Midwest.
June 7 - A natural gas pipeline explosion on a line owned by Enterprise Product Partners in North Texas killed one person. The 36-inch (91-cm) pipeline exploded 15 miles south of Godley, Texas. An electrical crew was digging a hole when it struck the gas pipeline. Enterprise violated several state regulations including adequately marking the path of the pipeline, according to the Texas Railroad Commission.
June 7 - An explosion and resulting fireball burned seven members of a crew drilling for natural gas at an abandoned coal mine in West Virginia, the second big fire at an energy project in the region in less than a week.
June 4 - Workers capped a natural gas well in central Pennsylvania after it ruptured during drilling, spewing gas and drilling fluid 75 feet in the air. The well, operated by EOG Resources Inc blew out when a drilling team was preparing to extract gas. No one was killed or injured, but officials later ordered the company to halt natural gas drilling in the state.
April 20 - Explosion and fire on Transocean Ltd's drilling rig Deepwater Horizon licensed to BP; 11 workers were killed on the rig stationed in deep waters south of Louisiana. The runaway oil well spilled up to 4.9 million barrels before it could be capped in mid-July, according to government estimates, making it the worst offshore oil spill in history.
April 5 - An explosion at the Upper Big Branch coal mine in Montcoal, West Virginia, killed 29 miners in the deadliest U.S. mining disaster since 1972. The mine owned by Massey Energy has had a worse-than-average injury rate over the last 10 years, with three fatalities since 1998.
April 2 - Four workers died in a blaze at Tesoro Corp's refinery in Anacortes, Washington, in the worst U.S. refining disaster since 2005. The fire resulted from equipment failure in a highly flammable unit producing naphtha at the plant.
March 2 - A fire on an asphalt tank under construction killed two workers at Holly Corp's Navajo refinery in Artesia, New Mexico.
