HOUSTON (Reuters) - U.S. energy companies on Thursday began airlifting workers from Gulf of Mexico oil production platforms and moved vessels from the path of what could become a devastating hurricane by the weekend.

A storm is brewing in the Caribbean Sea and is forecast to grind through the main oil-producing region of the Gulf this week. It could become a major hurricane ahead of landfall on the central Gulf Coast, the National Hurricane Center said. Hurricanes with winds of up to 111 miles (178 km) per hour are classified as major and can bring devastating damage onshore.

BHP, Chevron (NYSE:CVX), Equinor and Royal Dutch Shell (LON:RDSa) have begun removing workers from their offshore facilities, spokespeople said. BHP, Shell and Chevron are beginning with non-essential staff while Equinor said it is preparing to move workers off its Titan platform.

BHP aims to fully evacuate its Shenzi production platform and shut-in its production by Friday. Chevron said its production remained at normal levels on Thursday.

Gulf of Mexico offshore wells account for 17% of U.S. crude oil production and 5% of its dry natural gas production. Over 45% of total U.S. refining capacity lies along the Gulf Coast.

The preparations comes nearly four years to the day that the Gulf Coast was hit by Hurricane Harvey, which dumped several feet of rain in areas of Texas.

"This storm has the potential for rapid increases in intensity before it comes ashore" because of extremely warm waters off Louisiana, said Jim Foerster, chief meteorologist at DTN, which provides weather advice to oil and transportation companies.

"Water temperatures are 85 degrees to 88 degrees Fahrenheit (29-31 degree Celsius), that's anomalously high, 3 to 5 degrees higher than it normally would be," said DTN's Foerster. Its projected path over warm waters will mean it drops heavy rains that cause onshore flooding as it nears the Gulf Coast, he said.
