Nord Stream and the buzz about “dark ships”
Posted in pipelines, Russia, UK, tagged AIS, dark ships, Nord Stream, pipeline rupture on November 14, 2022| Leave a Comment »

Using satellite data, SpaceKnow detected 2 “dark ships” near the pipelines prior to the explosions. The ships were operating with their automatic identification system (AIS) transponders turned off or malfunctioning. While this is cause for suspicion, no data were provided on the frequency of such issues in the Baltic. Also, what were the specific routes and timelines for these vessels? Absent this information. the “dark ship” reports aren’t terribly meaningful.
Although the assumption that the explosions occurred outside the pipeline seems most likely, some observers have suggested that the explosions were internal. It’s unknown whether the investigators have ruled out this possibility.
Meanwhile, the folks in Germany and elsewhere in Europe are understandably impatient. They want answers from their governments!

Nord Stream: Russia blames UK navy

LONDON, Oct 29 (Reuters) – Russia’s defence ministry said on Saturday that British navy personnel blew up the Nord Stream gas pipelines last month, a claim that London said was false and designed to distract from Russian military failures in Ukraine.
No evidence was presented to support the Russian claim; nor was any information provided on the results of their blitz investigation.
Will the Russian Nord Stream investigation be the first to be released?

It looks like it might be.
Nord Stream AG, or the operator of Nord Stream 1 pipeline, sent a specially equipped vessel on Thursday to investigate damage to the pipelines under the Baltic Sea.
Nord Stream AG, whose majority shareholder is Russia’s state energy giant Gazprom, said the chartered vessel arrived at the location of damage in Sweden’s exclusive economic zone.
The vessel, bearing the Russian flag, would have specialists aboard to assess the damage within a day and investigation would take three to five days, the company said.
Nord Stream AG said it didn’t have relevant permits to conduct an investigation until now.

That’s a fast investigation!

Nord Stream methane release – some perspective
Posted in climate, pipelines, seeps, tagged methane inputs, NordStream, Oil in the Sea, pipeline leaks on October 4, 2022| Leave a Comment »
Sept 30 (Reuters) – The ruptures on the Nord Stream natural gas pipeline system under the Baltic Sea have led to what is likely the biggest single release of climate-damaging methane ever recorded, the United Nations Environment Programme said on Friday.
“This is really bad, most likely the largest emission event ever detected,” Manfredi Caltagirone, head of the IMEO for UNEP, told Reuters. “This is not helpful in a moment when we absolutely need to reduce emissions.”
Researchers at GHGSat, which uses satellites to monitor methane emissions, estimated the leak rate from one of four rupture points was 22,920 kilograms per hour. That is equivalent to burning about 630,000 pounds of coal every hour, GHGSat said in a statement.
The Nord Stream methane release, while puzzling and rather frightening given the potential for escalating international tensions, was not an environmental disaster or even a major environmental setback.
Some perspective:
- estimate for the main Nord Stream leak (likely the maximum or near-maximum rate) = 22,930 kg/hr
- 22,930 kg/h = 550,320 kg/day = 550.320 x 106 g/day
- total methane source for North American coastal waters (NASEM, Oil in the Sea, p. 63) = 4 – 20 Tg/yr
- 10 Tg/yr (i.e. 10 x 1012 g/yr) = 0.027 x 1012 g/day = 27000 x 106 g/day
- This is ~50 times the temporary (maximum?) daily rate for the Nord Stream leak
- North American input from seafloor seepage only (NASEM, Oil in the Sea, p. 63) = 2 – 9 Tg/yr
- assuming 5 x 1012 g/year or 13700 x 106 g/day
- This is ~25 times the temporary (maximum?) daily rate for the Nord Stream leak
German Navy to join Nord Stream investigation; Russia to investigate (presumably separately)

Germany’s navy is contributing to the investigation into the Nord Stream 1 and 2 gas pipeline leaks, said Defence Minister Christine Lambrecht, who added that the situation must be clarified and those responsible must be identified quickly.
Reuters
Russia’s FSB security service is investigating the damage sustained by the Nord Stream gas pipelines under the Baltic Sea as “international terrorism”, the Interfax news agency cited the general prosecutor’s office as saying on Wednesday.

Meanwhile, “the U.S. is supporting efforts to investigate,” whatever that means.
