Mexico’s state oil company Petróleos Mexicanos (Pemex) said a fire Saturday at the Akal-B offshore platform in Campeche Bay left one worker dead and nine injured, including two in critical condition.

The deceased worker was an employee of a contractor company called COTER.

The incident occurred in an area where pipelines supply natural gas as a fuel for the platform’s turbomachinery, Pemex said. 

One of the workers in critical condition is a Pemex employee, while the other works for COTER.

Pemex said it was investigating the cause of the blaze and taking actions that would allow the restart of operations. 

The fire is the latest in a long series of fatal accidents at Pemex oil and gas installations.
