Top offshore oil and gas producers on Friday were evacuating non-essential employees from production platforms in the US Gulf of Mexico due to the threat of Hurricane Dorian.
BP, Chevron Corp and BHP Group said they were or were in the process of removing some workers from their premises as a precaution. Each offshore oil and gas production was not affected.
Dorian is expected to hit Florida's Atlantic coast early next week as a major hurricane. Some computer models project that Dorian can cross the Florida peninsula and enter the Gulf of Mexico.
Gulf of Mexico oil and gas operations account for 16% of US crude oil production and about 4% of US natural gas.
The planned evacuations were completed on BP's Atlantis, Mad Dog, Na Kika and Thunderhorse platforms, and Chevron's Petronius and Blind Faith platforms, the companies said. BHP will remove nonessential workers from its Neptune and Shenzi production facilities on Saturday, a spokeswoman said.
Exxon Mobil Corp and Occidental Petroleum said they are closely monitoring Dorian, and their Gulf of Mexico operations are operating normally.
Other oil companies with operations in the US-regulated northern Gulf of Mexico have not responded to requests for comment on offshore operations.
Chevron said its Pascagoula, Mississippi, refinery is still monitoring the storm.
Shell Oil Co, a US arm of Royal Dutch Shell Plc, has not modified operations at the Norco and Convent refineries in Louisiana, according to spokesman Ray Fisher. Shell spokeswoman Cynthia Babski said operations abroad were unaffected by the threat of the storm.
