摘要：

The failure data available for power, navigation, propulsion and steering systems onboard LNG carriers, during critical manoeuvres in the final harbour and berth approach phase, are often accompanied with a high degree of uncertainty. For this reason the use of conventional probabilistic risk assessment methods may not be well suited. The approach described uses fault tree analysis to calculate the fuzzy probability of systems failure. The risks associated with failure events are determined by combining their occurrence likelihood (probability) and possible consequences to produce a risk ranking.
