AN EXAMINATION OF SOME STRUCTURAL LIMIT STATES FOR HYDROCARBON EXPLOSIONS

This paper examines how limit states can be applied in the assessment of the consequences of hydrocarbon explosions. A conditional structural reliability analysis approach is used to account for both the likelihood of the explosion occurring and exceedance of a structural limit state. The structural limit state is expressed in terms of deflection limits. Typical offshore topside explosion events lie in the range 10(-3) to 10(-5) per year. Typical overpressure versus probability of exceedance curves are used to determine possible loads for a simply supported beam. Annual probabilities of failure are determined for a range of hydrocarbon explosion probabilities accounting for uncertainties in the loading, response and strength. The effect of structural system strength enhancement is simply accounted for. For a target probability of failure of 10(-5), load and resistance partial factors are determined.
