At least one contractor was killed after a fire struck an offshore platform operated by Mexico's national oil company Pemex, the firm said in a statement on Sunday, adding that two others were in "grave" condition.
A total of nine workers suffered injuries in the blaze on Saturday afternoon that struck the company's Akal-B platform, located in the southern Gulf of Mexico, where most of Pemex oil output originates.
Five of the nine were Pemex employees while the rest were contractors from local service providers Diavaz and COTER.
A day earlier, Pemex said only two of its employees had been injured, and that none of the injures were serious as the fire had been controlled in 16 minutes, opens new tab.
Pemex infrastructure across Mexico has for years suffered frequent deadly accidents, which analysts often blame on poor maintenance and other operational deficiencies.
The Akal-B platform is part of Pemex's aging but still significant Cantarell complex of shallow water wells. The complex currently produces some 200,000 barrels per day of crude oil, but two decades ago was one of the world's top producing fields with over 2 million bpd of output.
In its statement, Pemex did not detail how oil and gas production from the complex had been affected. It did note that the company continued to investigate the cause of the incident as well as actions needed in order to "reestablish" operations at its processing center.
