Quantitative risk assessment techniques are increasingly being applied to facilities that involve (or are perceived to involve) hazardous processes. A fault tree analysis was performed for three standardized design classes of offshore plattforms to predict the frequency of the failure of the platform safety shutdown system (PSSDS) to mitigate such hazards as overpressure, fires, explosions, releases of flammable or toxic materials, vessel and compressor knockout drum overfill, and gas blowby. The analysis evaluated the logic processing units (LPU) (both electronic and pneumatic), end-devices and sensors, and calculated PSSDS unavailability in response to a challenge (covert fault). Platform risk was categorized through the assignment of specific consequence categories to each hazard type. A calculation of platform nuisance shutdown (overt fault) frequency as also performed. The fault tree models developed for the platforms provided the basis for sensitivity studies which examined a number of design and operations modifications. This provided a firm basis to the designer and to management for the definition of optimized design and operations schemes for the next generation of offshore platforms.
