In 2003, the standard was restructured into two parts:
For decades, engineers and integrity managers have relied on a single, critical standard to mitigate this risk: (formerly NACE MR0175). The 2021 revision of this standard represents the cutting edge of materials selection for sour service.
AMPP is already working on updates related to:
Data-Driven Probability Mapping: Operators are advised to develop a likelihood-of-corrosion model combining weighted contributors: CP potential trends, coating age/type and condition, soil resistivity and chemistry (pH, chloride, sulfate), topography and drainage, and historical excavation findings. The 2021 guidance encourages use of statistical scoring and, where available, machine-learning approaches to combine disparate data streams.
