ABSTRACT

With increased demands for goal-setting safety regimes in the offshore industry, structural reliability analysis is playing an increasingly prominent role in both design and reassessment. A range of relevant system reliability analysis techniques exist. However, they are computationally intensive and do not necessarily lend themselves to ready application within normal design environments. Consequently, a need exists for simpler techniques to determine platform reliability.

Recent platform reliability assessments are reviewed. Fifteen platforms are examined involving both ‘component’ and ‘system’ overall assessments. A component approach is identified to have the right level of simplicity. It is described and its practical implementation discussed. Its accuracy is compared with the results of a full system analysis.
