Thanks.
I can only relate what I have knowledge of.
We charged the pipe with water for weld integrity, then Nitrogen for gas-leaks.
Water has a high compressibility so if any part of the pipe is gonna burst, it will with water.
Finally, ultra dry Nitrogen to sweep any moisture and finally brought it to line pressure with product for FERC certification.
Note FERC doesn’t oversee EU pipelines.
