Russian company Novatek announced today that work at the gas terminal it operates in the Baltic has been suspended after a fire broke out there, which it said was the result of an “external influence”.

A fire broke out at a terminal owned by Novatek, Russia’s biggest liquefied natural gas producer, regional officials said, amid reports of explosions and the presence of a Ukrainian drone in the area.

“According to preliminary information, the fire was the result of an external impact,” the company said in a statement, without giving further details.

“The technological process at Novatek Ust-Luga has been stopped, and an operational headquarters has been established in order to minimize the consequences. Damages will be assessed later,” the company said.

The complex at Ust Luga, located in the Gulf of Finland about 170 kilometers west of St. Petersburg, converts stable gas condensate into light and heavy naphtha, jet fuel and ship fuel components, according to Novatek’s website. The port is used to transport processed products to international markets.
