Samenvatting:
This paper summarizes the results of a small benchmark exercise that wasconducted as part of the EU-sponsored project European Wind Turbine Standards
(EWTS-II). One of the objectives of the subproject 'Quantification of Failure
Probabilities' was to derive guidelines for the collection of data and for
the estimation of parameters to be used for quantitative safety and
reliability analyses of wind turbines. The preliminary guidelines set out
were finalized on the basis of the benchmark results. The benchmark case
consisted of a model of a hypothetical design, as defined and used in a
previous EWTS-1 subproject 'Assessment of Wind Turbine Safety: Recommended
Practices'. The model includes only one initiating event potentially leading
to (catastrophic) overspeed of the wind turbine. The accident sequences were
modelled with 3 event trees, 4 fault trees, and about 30 component failure
modes (so-called basic events). 8 refs.
