Hi all,
there was bulge on last shell due to some weld destortions during welding clips outside.
it was noticed just in Final walkdown inspection before hydrotest.
Subcontractor which is constructing the tank just put new weld on the shell from inside thinking it gives to shell reinforcement and helps the buchkling go out. It worked out and buckling gone. After that the MPI was done after grinfing the weld.
But all this done was done without informing the Client (Owner). Without any repair procedure. Now Non conformance report is assued by them and i need to close this. I will upload pictures . What should write on NCR to close as per repair procedure. pls help me.
