Underpinned by our wave and hydrodynamic modelling expertise, our coastal and marine forecasting services combine global and regional wind and wave forecasts with high resolution local wave transformation (e.g. SWAN, TOMAWAC and ARTEMIS), hydrodynamic models (e.g. TELEMAC 2D/3D) and response models. This ensures that the timescales and the areas covered by our forecasts are as precise as possible, so that decisions can be made using information which is genuinely site-specific, and include regular updates and warnings relevant to the constraints of the particular site and operation.
In the case of a typical offshore wind farm forecast, for example, the forecasts of the metocean conditions are supplied on a customised and secure website with forecasts updated up to four times a day. The forecasts show the variability in conditions across the development area, and warnings are given when predicted conditions exceed the defined safe operating thresholds. In situ measurements, when available, can also be presented to confirm the accuracy and confidence in the forecasts.
We work with the UK Met Office and a range of other suppliers of offshore forecasts such as the European Centre for Medium-Range Weather Forecasts (ECMWF) who provide the boundary conditions to our local area high resolution forecast models.
