Extreme Value Analysis
Statistical estimation of rare events (waves, wind, water level) and their return periods, to size offshore structures against robust, defensible design criteria.

Designing against rare events
An offshore structure is built to withstand what almost never happens. Extreme value analysis estimates the intensity of rare events, such as the 50-year storm or the 100-year wave, from records that, by their nature, contain few of them. This is the heart of the doctoral expertise Analyzenn draws on, applied to your design criteria.
Our scope
- Univariate extremes: distribution fitting (GEV, GPD), threshold selection, return periods and confidence intervals.
- Multivariate and conditional approaches: combinations of variables (wind-wave, wave-level) for realistic load cases.
- Uncertainty quantification: sensitivity to method choices and sample length, clearly documented.
What you get
Justified design criteria backed by a transparent methodological note on assumptions and uncertainties, enough to defend your choices before a certification body and your own teams alike.
