HOUSTON, Sept 27 (Reuters) - About 11% of oil production in the U.S. Gulf of Mexico was shut on Tuesday as a powerful Hurricane Ian forced oil companies to evacuate workers and the storm took aim at Florida.
The hurricane entered the U.S. Gulf of Mexico on Tuesday and is forecast to become a dangerous, Category 4 storm over the warm waters of the Gulf, according to National Hurricane Center (NHC) forecaster Eric Blake.
Ian weakened after crossing Cuba and was packing winds of 120 miles per hour (195 km per hour), the NHC said. It is heading toward making an extremely dangerous landfall in southwestern Florida, Blake predicted.
Some 190,000 barrels per day of oil production, or 11% of the Gulf's total were shut-in, according to offshore regulator the Bureau of Safety and Environmental Enforcement (BSEE). Producers lost 184 million cubic feet of natural gas or nearly 9% of daily output.
Personnel were evacuated from 14 production platforms and rigs, BSEE said.
It is the first hurricane this year to disrupt oil and gas production in the U.S. Gulf of Mexico, which produces about 15% of the nation's crude oil and 5% of dry natural gas. Ian's course takes it east of the core of U.S. offshore oil and gas production.
"The storm is so massive, it's going to affect all of Florida," said Jim Foerster, a consulting meteorologist at data and analytics firm DTN. "This is going to be really, really bad."
Ian will be "very impactful, not only to the offshore operations, but certainly, there will be tens of thousands of people without power over land," Foerster added.
Tampa Electric said it will proactively cut off service to customers and warned that they should be prepared for "extended power outages."
BP (BP.L) said it was working to redeploy offshore personnel to two offshore production platforms after determining Hurricane Ian no longer posed a significant threat to its Gulf Of Mexico assets. The oil major had on Monday evacuated personnel and halted output at Na Kika and Thunder Horse platforms.
Chevron also removed staff from two platforms, while Occidental and Hess said they were implementing storm procedures without providing specifics.
Tankers and vessels cleared the eastern Gulf of Mexico region, Refinitiv Eikon ship tracking showed.
