This paper reports that ARCO Alaska Inc. has developed a method for determining the maximum allowable operating pressure (MAOP) in a corroded pipeline. This method incorporates modifications of the ASME/ANSI B31G criterion to correct for its being overly conservative. The method is based on procedures which allow evaluation of large areas of metal loss, corrosion in some welds, groups of noncontinuous pits and, to a limited extent, the effect of circumferential corrosion.
