Resumen

A computer software to assess wall thickness loss and weld thickness loss in offshore pipelines is presented.  This software calculates the thickness loss through a data bank obtained using computational modeling based on Monte Carlo MCNPX code, and  digital radiography images obtained using image plate (BaFBr) detector. In order to give users more flexibility, the computer software was written in Java, which allows it to run on Linux, Mac OS X and Windows. Tools are provided to image display, select and analyze specific areas of the image (measure average, area of selection) and generate profile plots. Applications of this software in onshore and offshore inspections are presented. Preliminary results shown good agreement between real and calculated value of thickness loss.
