Probability of failure for fixed offshore structures determination: an analysis of a braced monopod and 4-legged platforms with respect to industry standards / Ezanizam Mat Soom ... [et al.]

The structural integrity is susceptible to a combination of statistical and engineering design uncertainties that may remain flexible as long as the structure can successfully manage the encountered load. There are many methods for determining the probability of failure (POF) in the oil and gas sect...
