We have been conducting integrity investigations for 50 years and can provide immediate RSTRENG along with all other fit for service calculations.
We have taken this ability to a new level with the ProSCAN laser profile scanner. By scanning the corrosion with the laser we are able to provide an "effective area" RSTRENG calculation in minutes. An effective area RSTRENG is much more accurate but is also always much more time consuming due to the number of measurements that must be taken. The ProSCAN not only reduces the time required to capture mission critical data but significantly increases accuracy. With increased accuracy comes increased confidence that you are making the right call on repair decisions which could potentially save thousands on a dig program.
This image (produced using VirtualPIPE) visually demonstrates a cross section view of the corroded area. It shows the amount of metal loss and the total size of the effected area. In this case the B31G safety factor is 1.44 while the Effective area calculation is 1.58 or approximately 10% better.
