2/ It's hilarious that Lloyds&Arch know that all of the bombs were placed on field joints. The successful Nord Stream 1 bombs unleashed propulsive forces from the gas which catapulted the pipeline segments and debris over an area 250 meters long and 50 meters wide. Only the investigation which recovered debris and analyzed explosive residue could know the exact bomb placements on these sites. From what I have heard, not even Nord Stream has access to this classified information. But apparently Lloyds has.
Full paywalled article here. The harbor master isn't making this up. He wasn't alone on the rescue vessel ordered to stay clear of the American warships. 
2/ "The Dent" is located on the "B-String" of Nord Stream 1, and very close to the location of the bomb on the A-String of Nord Stream 1 in the Swedish EEZ (red marker here) 
I have requested the documents from the court and I'm making them available here. The defense filing has a lot of references to the claim doc so I publish download links to both: 
2/ Normand spent many hours over each of the explosion sites and its movements seem to support dive operations. 
2/ My first assumption is that if you can design a material with the same sound speed and attenuation as water, that material (if homogeneous) becomes totally invisible to sonar surveillance. Nothing else matters. Right or Wrong?
2/ Each pipeline has two "Strings" which are accurately drawn on the navigational chart. For NS2 we know from official docs which one of the strings is A and which is B. I used the same nomenclature for NS1. 
2/ The low altitude mission started less than 1 hour away from #NordStreamSabotage sites at low-altitude speed (250 kts). Since it was dark for 4 hours there was plenty of time to spend right above explosion sites and drop a buoy.
