'External Corrosion of Oil and Natural Gas Pipelines,' a free preview chapter from ASM Handbook, Volume 13C, Corrosion: Environments and Industries:
Of special interest, note the 'Intelligent pig' (Magnetic flux leakage detector) for detecting thin spots in the pipeline wall, Figure 14. The tail end sensors determine whether internal or external thinning.
Don't know if this type was used by BP, but looks to me like the pipeline must be pretty well cleaned before use.
Note: also available are the preview chapters on the corrosion of Magnesium and of Hafnium, from ASM Handbook, Volumes 13A and 13B, respectively
