NATO to respond if Baltic Sea pipeline damage deliberate - alliance chief

NATO will discuss damage to a gas pipeline and data cable running between member states Finland and Estonia, and will mount a “determined” response if a deliberate attack is proven, NATO Secretary General Jens Stoltenberg said on Wednesday.

Damage to the Balticconnector pipeline and telecommunications cable was confirmed on Tuesday after one of the two pipeline operators, Finland’s Gasgrid, noted a drop in pressure and possible leak on Sunday night during a storm.

Helsinki, which is investigating, has said the damage was probably caused by “outside activity”. That has stoked concern over regional energy security and pushed gas prices higher.

“The important thing now is to establish what happened and how this could happen,” Stoltenberg told reporters in Brussels ahead of a meeting of the military alliance.

“If it is proven to be a deliberate attack on NATO-critical infrastructure, then this will be, of course, serious, but it will also be met by a united and determined response from NATO.”

Finland’s National Bureau of Investigation said “external marks” had been found on the seabed beside the damaged pipeline and that it was reviewing the movements of vessels in the area at the time of the rupture.

“We are now focusing on the technical investigation of the pipe damage site and examining the seabed at the scene,” bureau chief Robin Lardot told reporters on Wednesday.

Risto Lohi, the bureau’s chief investigator, told a news conference that anchor damage had not been ruled out, adding: “At the moment it looks like the damage was caused by mechanical force, not an explosion.”

The pipeline runs between Inkoo in Finland and Paldiski in Estonia across the Gulf of Finland, part of the Baltic Sea which stretches eastward into Russian waters and ends at the port of St Petersburg.

PIPELINE ‘PULLED FROM ONE SIDE’

“It can clearly be seen that these damages are caused by quite heavy force,” Estonian Defence Minister Hanno Pevkur told Reuters, with possible causes including “mechanical impact or mechanical destruction.”

The pipeline and telecoms cable run in parallel at a “significant” distance from each other, according to the cable operator, Elisa.

The two were damaged “within the same time frame” early on Sunday, Finnish investigators said, with the pipeline break believed to have been in Finnish waters while the cable breach was in Estonian waters.

The pipeline, encased in concrete for protection, looks like “someone tore it on the side”, Estonian Navy Commander Juri Saska told public broadcaster ERR. “The concrete has broken, or peeled off, specifically at that point of injury.”

The damage would not impact Finland’s electricity system, grid operator Fingrid said. Gas accounts for 5% of Finland’s energy needs.

The Balticconnector pipeline opened in December 2019 to help integrate gas markets in the region, giving Finland and the Baltic nations of Estonia, Latvia and Lithuania more flexibility of supply.
