The operator's account
Pemex reported a gas leak and fire at sea on July 2, 2021 near its KU-C satellite platform in the Ku-Maloob-Zaap production area in the Gulf of Mexico. Its statement located the leak in a 12-inch subsea pipeline about 150 metres from the platform.
The visual impression of an eye of fire on the water can obscure the mechanism. Escaping combustible gas supplied the fuel; seawater was not itself burning. The operator's account is evidence of what Pemex reported about its infrastructure, not an independent reconstruction of every contributing factor.

Pemex's 2021 sustainability reporting also recorded the July 2 event. Other reports from the same production area concern different dates and facilities, so injuries or operational losses from a later platform fire should not be automatically attached to these images.
For a historical incident, identify the date, facility and source before sharing footage as a new emergency. NewsCubby's World section provides current reporting, while the climate-science explainer explains a different subject: long-term warming evidence cannot, by itself, establish the cause of a particular industrial accident.
