Separate incidents raise eyebrows; pipelines not currently bringing gas to Europe due to Ukraine war

A series of unusual leaks on two natural gas pipelines running from Russia under the Baltic Sea to Germany triggered concerns about possible sabotage Tuesday, overshadowing the inauguration of a long-awaited pipeline in Poland that will bring Norwegian gas to Europe in efforts to bolster energy independence from Moscow.

Danish Prime Minister Mette Frederiksen said she cannot rule out sabotage after three leaks were detected over the past day on Nord Stream 1 and 2. The pipelines are not currently bringing gas to Europe as an energy standoff over Russia's war in Ukraine halted flows or never allowed them to begin. However, gas still fills the lines.

No official presented evidence of what caused the problems, but in central Europe where distrust of Russia runs high, there were fears Moscow sabotaged its own infrastructure in a gesture of spite or to signal that all pipelines are vulnerable to attack. The leaks emerged off the coast of Denmark and Sweden, raising the stakes on whether energy infrastructure in European waters was being targeted and leading to a small bump in natural gas prices.

Nord Stream AG said it was impossible to estimate when the gas network system's working capability would be restored.

We are talking about three leaks with some distance between them, and that's why it is hard to imagine that it is a coincidence, said Frederiksen.

Controversial Russian pipelines leaking into Baltic Sea

42 minutes agoDuration1:58Trent Murray in Berlin reports on the many questions raised over sudden, unusual gas leaks from Russia's Nord Stream 1 and 2 pipelines in the Baltic Sea.

Frederiksen was with Poland's President Andrzej Duda and Prime Minister Mateusz Morawiecki, opening a valve of a yellow pipe belonging to the Baltic Pipe, a new system set to bring Norway's gas across Denmark and the Baltic Sea to Poland beginning next week.

Each line of the pipeline consists of about 100,000 24-tonne concrete-weight coated steel pipes laid on the seabed of the Baltic Sea. The pipelines have a constant internal diameter of 1.153 metres, according to Nord Stream.

Sections of the pipelines lie at a depth of around 80-110 metres. Natural gas is methane, which partially dissolves in water and is not toxic. The deeper the gas is released in the sea, the higher the proportion that dissolves in the water.

The destruction that occurred on the same day simultaneously on three strings of the offshore gas pipelines of the Nord Stream system is unprecedented, the Nord Stream consortium said.

A Polish government official said he would not rule out the possibility of Russian provocations.

I cannot exclude any scenario. We are in a situation of high international tension, said Marcin Przydacz, a deputy foreign minister. Unfortunately, our eastern neighbour is pursuing an aggressive policy all the time.

'Very alarming': Russian government

Kremlin spokesman Dmitry Peskov called the leaks very alarming.

This is an unprecedented situation that requires an urgent investigation. We are extremely worried by this news, he said in a conference call with reporters.

Asked if the accident may have been caused by an act of sabotage, Peskov said that no version could be excluded.

Danish authorities said Monday that a leak was detected in the Nord Stream 2 pipeline, which has never been used. They later announced a major pressure drop on the parallel Nord Stream 1, which until recently has been a key source of gas to Germany.

The Swedish Maritime Administration said Tuesday that two leaks were discovered on Nord Stream 1, which partly runs in Swedish waters.

The leaks in the pipelines have been detected northeast and southeast of the Danish island of Bornholm.

The Danish Maritime Authority issued a navigation warning and established a prohibited area to ensure that ships do not go near the leaks. Ships may lose buoyancy if they sail into the area, and there may also be a risk of ignition above the water and in the air, the Danish authorities said. 

Energy concerns with winter looming

Because the pipelines aren't actively sending gas to Europe, the leaks did not pose any threat to energy supplies, and experts said the environmental impact would be limited.

With the continent needing gas to heat homes, generate electricity and run factories, the energy crisis provoked by Russia's war in Ukraine threatens rationing, business shutdowns and possible recession this winter.
