So the only citation of "enormous doubts" you provided from back in March was refuted by new information released since then. You provide zero new sources, just childish attempts to seed more doubt and uncertainty.
You clearly have not understand anything from what I've explained to you. I have quoted the maritime expert because he's a maritime expert and not an explosives expert. The operation is far more than xx kg of explosives. You don't do this sort of operation on a day trip. Not on this ship, not 100s of km from the German cost, where the Andromeda was rented, not for 3x blowing up the pipelines. 
But since you claim a possible Russian false flag has been refutet, you have not provided any proof, why it shouldn't be possible that Russia has left these traces on the "Ukrainian boat" intentionally.
The version of Russia leaving these traces of "light" explosives intentionally would be very plausible to make their story more "legitimate".
I'm always surprised to see people like you completely overlooking the fact that only 3 pipelines out of 4 were detonated. Guess what? Maybe people would see the clear picture that only Putin has to gain something to blow up 3 of 4 Pipelines of that useless gas pipeline.
Also important to note, that 2 pipelines of NS1 were blown up but only 1 pipeline of NS2. 1 pipeline from NS2 is still intact.
And - no surprise - shortly after the explosions, Putin suggested to open the remaining NS2 pipeline.

Not suspicious, that one pipeline is still intact and Putin wants to start his NS2 project to keep Germany dependent and fund his russian war machine - not suspicious at all.

The Russian leader offered to resume gas supplies through parts of the pipelines that weren't damaged by explosions last month.
