A ship and a barge containing nearly a million gallons of fuel collided and caused oil spill at a channel in the U.S. state of Texas Saturday, the U.S. Coast Guard said. The incident happened Saturday noon in the Houston Ship Channel in south Texas,the Coast Guard said in a news release. The barge, which contained 924,000 gallons of fuel oil, collided with a 585-foot (178-meter) bulk carrier. Operators of the barge activated its emergency response plan and all six crew members were accounted for and are in stable condition, authorities said. A sheen of oil has been reported on the water, but the quantity of product released is unknown at this time, according to the release. Authorities said the barge was traveling from Texas City to Bolivar at the time of the collision. The barge sunk into the dike eventually, officials said. Marine traffic in the affected stretch of the Houston Ship Channel has been temporarily suspended. And it's not immediately known when it will be reopened. Owner of the barge is working in a unified response with the U.S. Coast Guard and the Texas General Land Office on the scene. It was the second collision in the Houston Ship Channel in just over a week. On March 14, a cargo ship carrying grain collided with a barge carrying 840,000 gallons of fuel oil in the channel but did not cause any spill.
