An accurate characterization of offshore wind resource horizontal variability is a key for layout optimization. 

Offshore wind farm: key issues

Wind measurements offshore are tremendously difficult and costly. Although, because of these high costs and the lack of flexibility, the current market trend is moving towards the use of LIDARs mounted on buoys, maintaining these is also very difficult, especially during bad weather. Consequently, LIDAR downtime may lead to extremely undesirable data blackouts and the consequent penalties involved. This is where modeling comes into its own. 

Offshore wind resource assessment

Small differences in wind speed may result in very significant differences in power production. The use of mesoscale models has become a must during several stages of offshore wind farm development. Both mesoscale derived high-resolution wind resource grid files (Vortex-FARM) and high-resolution time series (Vortex-LES) at each turbine location can be of great use when analyzing relevant topics in offshore wind resource assessment such as wakes, curtailment issues or sector management, without having to resort to physically installing wind measurement apparatus.
