... and subsequently, the deterministic model is converted into a probabilistic model where reliability is a tunable factor. A large number of Monte Carlo simulation are conducted to generate probabilistic creep deformation, minimum-creep-strain-rate (MCSR), and stress-rupture (SR) predictions. It is demonstrated...

... operation is calculated with the classic reliability model. The pressure fluctuation due to emergency pressure relief is calculated with a proven-in-use relief model. Necessary assumptions are made about the relief operation. It is concluded that 2 out of 5 (2005) emergency relief valves are sufficient...
