A subsea pipeline was plastically deformed due to accidents. The outcome was the validation of the engineering ciritcal assessment (ECA) with maximum defect size.
A pipe coater experienced cracking issues in the top layer of dual layer fusion bonded epoxy systems (FBE) during large scale bending tests at low temperature. White spots show to be the preferred crack initiation location. The customer was advised to select a better adhering fusion bonded epoxy (FBE) and to optimise cleaning efficiency. Since, the pipe coater no longer experiences cracking issues.
