High resolution Magnetic Flux Leakage (MFL) inspection tools are very adept at showing the current static state of corrosion in a pipeline. A single inspection shows only a partial reflection of the actual corrosion activity. Multiple inspections and an accurate corrosion growth analysis are required to have a more complete understanding of the corrosion activity. It should then be possible to find features growing at a potentially critical rate and to differentiate between areas of new growth and areas of continued growth. The principal advantage of this is to more accurately predict future corrosion growth in a line. This paper is a highlight of two corrosion growth analyses and a method that has been developed to provide a more complete understanding of corrosion activity and growth. The method that has been developed enables a minimization of the primary errors involved in a corrosion growth analysis which has been through the usage of the raw signal.
