In these studies a detailed analysis of site specific data (including measurements if available) is performed to support engineering design and field operations. They provide a range of MetOcean and environmental parameters, derived using state of the art methods.
Deliverables are MetOcean design criteria at one or several locations. Extremes (independent & associated) are provided at requested return periods, optionally split by directions or seasons. Additionally, fatigue and environmental data can also be produced, tailored to Client’s requirements.
They typically include:
- Extreme wind, wave, water levels and currents at requested averaging periods
- Vertical wind profile definition
- Calculation of NSS (Normal Sea State), SSS (Severe Sea State), and ESS (Extreme Sea State)
- ISO-compliant maximum wave height and crest elevation
- Wave spectral analysis
- 2D and 3D I-FORM contours (Hs vs. Tp, Hs vs. Tp & Wind Speed,)
- Associated extremes (Hs-Wind Speed, Hs-Current, Wind speed-Current, etc)
- Split of cyclonic and non-cyclonic conditions as appropriate
- Measured time series gap-filling (by means of Radial Basis Function)
- Profile characterization or selection of representative cases (by means of Maximum Dissimilarity or K-Means Algorithms)
- Fatigue data (frequency distributions, percentage exceedance, misalignment tables, roses, etc)
- Individual waves
- Wave and flow numerical modelling as appropriate
Such studies typically take around 2-8 weeks.
