... lean of the drum relative to the adjoining support structure. This paper describes the inspection, engineering analysis, and repair performed after discovery of this challenging situation. Initial inspection included quantitative measurement of the drum displacement and skirt cracking. Engineering...

... Abstract The Primary Water Stress Corrosion Cracking causes existing ASME BPV Code Section XI inspection and repair methodology to need enhancement. This forms the basis for Code Case N-770 and revisions through 6. The paper includes the bases for examination requirements, examination schedule...

... be used by decision-makers (authorities, stockholders, owners and contractors) to structure budget allocation strategy for seismic risk mitigation measures such as repair, retrofit, and/or replacement of steel and concrete pipelines. A stochastic model is presented to establish optimal mitigation measures...

.... These sharpness growth rates were subsequently studied and their relationship with overall cycle times analyzed. The study also shows that individual coke drums can experience different sharpness growth rates and there can be a distribution of these rates. To determine when repairs should be conducted, coke drum...
