MODES computer program

Developed as a cost-effective alternative to physical testing for the prediction of explosive decompression (ED) in elastomer systems, the MODES computer program is over 88% accurate at predicting the onset of ED damage in seals. It enables engineers to assess an extensive range of what-if scenarios and design components and operating procedures to avoid failure. The software, a result of BHR Group’s MODES project, is available to sponsoring organizations and contains extensive data on the selected materials. It permits users to calculate safe minimum decompression times and the number of subcritical “ emergency” decompressions the seal can survive without damage, as well as seal performance under user-specified conditions. This allows engineers to optimize seal and housing design, perform sensitivity studies and risk analyses based on material variability and material type, and assess the effect of different fluids, pressures and temperatures.
