As the hurricane approaches Marco and the tropical storm Laura, energy companies have decided to suspend as a precaution the equivalent of 58% of oil production in the Gulf of Mexico, a US agency said on Sunday.

This corresponds to 1.07 million barrels per day.
The equivalent of 45% of natural gas production in the region has also been suspended, said the Office of Environment and Security Regulation (BSEE) in its latest inventory on Sunday around 19:30 GMT (3:30 p.m. to Quebec).
As a precaution, 114 production platforms out of the 643 platforms accommodating personnel were indeed evacuated to the Gulf of Mexico, which alone supplies 17% of American crude production.
Five drilling rigs were also evacuated, while eight other mobile drilling rigs were moved out of planned trajectories for Marco and Laura.
All facilities will be inspected after their passage and will be able to resume production immediately, the agency said.
According to the Miami-based National Hurricane Center (NHC), Marco turned into a hurricane on Sunday and was due to traverse the central Gulf of Mexico in the day before approaching the US state of Louisiana on Monday.
Eye of the storm Laura moved Sunday through Haiti and the Dominican Republic, then expected to be near or over Cuba Sunday evening and Monday, and over the southeastern Gulf of Mexico Monday evening and Tuesday. According to the latest NHC forecast, it should then approach the central and northwestern Gulf of Mexico on Tuesday evening and Wednesday.
