Leaks hit Russian undersea gas lines

European countries are racing to investigate unexplained leaks in two Russian gas pipelines running under the Baltic Sea near Sweden and Denmark.

Experts and also Russia, which built the network, said the possibility of sabotage could not be ruled out.

Sweden’s Maritime Authority issued a warning about two leaks in the Nord Stream 1 pipeline, shortly after a leak on the nearby Nord Stream 2 pipeline was discovered that had prompted Denmark to restrict shipping in a five nautical mile radius.

Both pipelines have been flashpoints in an escalating energy war between European capitals and Moscow that has pummelled major Western economies, sent gas prices soaring and sparked a hunt for alternative energy supplies.

“There are some indications that it is deliberate damage,” said a European security source, while adding it was still too early to draw conclusions. “You have to ask: Who would profit?”

Russia also said the leak in the Russian network was cause for concern and sabotage was one possible cause. “No option can be ruled out right now,” Kremlin spokesman Dmitry Peskov told reporters.

Neither pipeline was pumping gas to Europe at the time the leaks were found amid the dispute over the war in Ukraine, but the incidents will scupper any remaining expectations that Europe could receive gas via Nord Stream 1 before winter.

“The destruction that occurred on the same day simultaneously on three strings of the offshore gas pipelines of the Nord Stream system is unprecedented,” said network operator Nord Stream AG.

“It is not yet possible to estimate the timing of the restoration of the gas transport infrastructure.”

Although neither were in operation, both pipelines still contained gas under pressure.

Denmark’s energy minister Dan Jorgensen said in a written comment leaking gas had been detected in Nord Stream 2 on Monday between Russia and Denmark.

Gazprom, the Kremlin-controlled company with a monopoly on Russian gas exports by pipeline, declined comment.

Russia slashed gas supplies to Europe via Nord Stream 1 before suspending flows altogether in August, blaming Western sanctions for causing technical difficulties. European politicians say that was a pretext to stop supplying gas.

The new Nord Stream 2 pipeline had yet to enter commercial operations. The plan to use to supply gas was scrapped by Germany days before Russia sent troops into Ukraine in February.
