BP temporarily revealed on Tuesday that it shut down its Thunder Horse semi-submersible platform in the Gulf of Mexico the day before because of a power outage, according to Reuters.
Its 300 personnel were evacuated but technical and essential staff were set to return later on Tuesday.
Located about 150 miles southeast of New Orleans, Thunder Horse is the largest offshore facility of its kind.
At maximum capacity, it can produce 265,000 bpd.
Less than two weeks ago the platform had been evacuated in anticipation of Hurricane Irma.
