German Navy Commander: Russia's capabilities at the bottom of the sea - Germany KNEW

FGS Sachsen arriving in Tallinn on September 30, 2022

Vice Admiral Jan Christian Kaack, Commander of the German Navy in an interview on 3 Nov 2022.

[MRT: J.Ch. Kaack knew that the UK was threatening Nordstream pipelines. German, French and allied ships were protecting pipelines, searching for the undersea asset but in the wrong area, closer to the Lithuania. There is a strong case to believe that Norway warned not just the USA but also France and Germany about the UK plans to take down Nordstream.]  

"One of these challenges arose. One day before the Nord Stream 1 and 2 incident, I gave an interview to an influential German newspaper, where I gave a strong recommendation to thoroughly assess Russia's capabilities at the bottom of the sea," he said.

[MRT: Why would he do that? To start to blame Russia or to show that Russia has all its submarines out of the area so Russia would not be blamed which could ease the tense situation?]

"The basis for seeing possible events is a clear picture of the sea, or observation. If there is a clear picture of the air, surface or subsurface — almost clear, because you cannot always be completely sure — then you can look at anomalies in the system and then you can bring a special unit to the area where the anomaly was detected," Kaack said.

[MRT: stress should be in the word "...anomalies..." which hints to subsurface approach. It would be important to know what orders got German ad allied ships in the week before the event. Especially AFTER the USS Kaersarge left the Baltic sea as described here and Europeans were no more sheltered by US nuclear umbrella as said here. The next day was a chaos.]

Summary: 

The head of German Navy J. Ch. Kaack seemed to be aware of the subsurface danger to Nordstream pipelines. 

Kaack tells that the surface and air were under surveillance.

Kaack tells that there is an evidence in data anomalies about what happened.

It is unclear why German ship FGS Sachsen was in NE part of the Baltic sea in 30th of September when it was on 27th of September near the other end of Nordstream, neear its exit to Germany - here. Note that French naval ship Céphée was also in the same time operating in the NE part of the Baltic sea. Why? Was Germany expecting the attack in a wrong area?
