A natural gas pipeline off the coast of Louisiana was closed Monday in response to a deadly accident, Chevron Pipe Line Co. said.

Chevron was mum on the details surrounding the accident, but revealed a contract worker died and two others were injured while performing routine maintenance on a pipeline at a site six miles off the coast of Louisiana.

The company said in a statement it "regrets" the accident and announced the pipeline was shut down Monday so a site investigation can proceed.

Chevron's pipeline provides fuel to the Henry Hub storage facility in Louisiana, considered the benchmark site for U.S. gas pricing. Chevron Pipeline Co. said it was rerouting most of the gas to through a different pipeline.

Louisiana officials said the line experienced a valve failure Saturday. There were no reports of sheen at the site.
