Three workers are missing following the huge blaze on a Pemex dehydration and pumping platform Wednesday in the Gulf of Mexico that killed four workers and burned for hours.
Petroleos Mexicanos, or Pemex, said it became aware of the missing workers when it recounted personnel after the fire on the Abkatun-A Permanente shallow-water platform in the Campeche Sound.
One of the missing workers was from Pemex and the other two worked for contractor Cotemar, the company said.
Investigators were still trying to determine the cause of the blaze, which injured 45 people, two seriously, and forced the evacuation of 300 workers.
Pemex, Mexico’s state oil company, said it managed to avert any significant oil spill.
Officials said environmental damage ended up avoided because the fire happened on a processing platform where workers could shut off the feeder lines, rather than at an active oil well with a virtually unlimited amount of fuel flowing up from the seabed.
Pemex director general Emilio Lozoya said the accident “would have a minimal impact on production, because this was a processing platform,” not a producing well.
On Wednesday, helicopters flew workers with bandaged hands and faces and burn marks on their overalls to the nearby city of Ciudad del Carmen, where crowds of relatives of oil workers thronged outside hospitals.
Survivors said the blaze engulfed the platform, forcing people to leap into the sea or flee in evacuation boats.
