Seoul Gazette - 'External activity' probably behind Finland-Estonia gas pipe leak

Last year there were a series of underwater blasts that ruptured three pipelines that carried natural gas from Russia to Western Europe, at a time of high geopolitical tensions as Moscow cut gas supplies to Europe.

But the government cautioned against leaping to any conclusions at this stage about the latest leak, as authorities said it seemed unlikely that explosives were the cause.

Niinisto said that he had been in touch with NATO secretary-general Jens Stoltenberg, and that the military alliance was ready to assist in the investigation.

"It is likely that the damage to both the gas pipeline and the telecommunications cable is the result of external activity," Niinisto said.

He said the cause of the damage was not yet clear, and that Finland and Estonia were cooperating in an ongoing investigation.

Prime Minister Petteri Orpo told reporters later that a preliminary assessment suggested that "the discovered damage could not have been caused by normal use of the pipeline or pressure fluctuations."

He said that the leak was located in the Finnish Exclusive Economic Zone.

When asked about the likelihood of Russian involvement, Orpo said it was important to "gather all the information that is available and not to jump to conclusions at this stage."

Head of the investigation department at the National Bureau of Investigation, Timo Kilpelainen, said at the same press conference that there was "no indications that explosives were used in the act."

NATO chief Stoltenberg posted on X, formerly known as Twitter, that the military alliance was "sharing information and stands ready to support Allies concerned."

- 'Unusual drop in pressure' -

Finland's gas network operator, state-owned Gasgrid, said Sunday that the Balticconnector pipeline had been shut down over a suspected leak.

The operator said "an unusual drop in pressure" had been noticed in the pipeline running along the seabed of the Gulf of Finland.

Gasgrid added that the Finnish gas system was stable, with supply secured through a floating liquefied natural gas terminal (LNG) in Inkoo.

In late September 2022, a series of underwater blasts ruptured three of the four pipelines that make up Nord Stream 1 and Nord Stream 2, a major conduit for Russian natural gas exports to Western Europe, spewing gas into the Baltic Sea.

The pipelines had been at the centre of geopolitical tensions as Russia cut gas supplies to Europe in suspected retaliation to Western sanctions over Moscow's invasion of Ukraine.

Because the leaks occurred in their exclusive economic zones, Denmark and Sweden opened probes into the attack, as did Germany.

All three countries have kept a tight lid on their investigations, which analysts say is unsurprising given the potential diplomatic fallout of what they might uncover.

- Inspection underway -

The Balticconnector has been the only gas import channel to Finland, apart from LNG, since Russian imports were halted in May 2022, following Moscow's invasion of Ukraine.

Gasgrid said Tuesday it had begun its inspection of the pipeline by conducting measurements "with the purpose of determining the location and extent of the predicted damage," adding that the inspection would be carried out in stages during the week.

It added that once measurements were completed repair plans for the pipeline could be made.

Despite the shortfall, Gasgrid said the Inkoo LNG terminal had "the capacity and the ability to deliver the gas Finland needs in the coming winter as well", even though consumption is usually higher in winter.

Telecom operator Elisa also confirmed Tuesday it was experiencing a disruption caused by a "cable break" during the weekend.

"The disruption has no impact on Elisa's services as it is a backup connection," the operator said in a statement.

Russia stopped supplying gas to Finland after it refused to pay in rubles, a condition imposed on "unfriendly countries" -- including European Union member states -- as a way to sidestep Western financial sanctions against Russia's central bank.

Natural gas accounts for around five percent of Finland's energy consumption, mainly used in industry and combined heat and power production.
