The provision of high quality and reliable metocean data is fundamental for the success of marine projects. Daily as well as extreme conditions have to be taken into account to establish the design conditions. Marine operations likewise rely heavily on metocean data for predicting available weather windows. In essence all actors on the marine stage need this information. The need varies but may typically include for example time series and maps presenting hindcast and forecast of currents, sea surface heights, wave climate, temperature, salinity levels and stratification.
Monitoring systems
At DHI we have more than 40 years of experience with monitoring programs worldwide designed to collect the required data. DHI’s activities range from design and implementation of monitoring systems to data acquisition, transmission, analysis, display and storage. Monitoring systems are often integrated with forecast systems using DHI’s suite of numerical model
Hindcast
Design data is typically based on hindcasts, where meteorological data is used to derive wave conditions, sea levels and currents based on the wind and pressure data. Available hydrographic data is used to calibrate and validate the models and validated models are then applied to produce e.g. 50 years of hindcast data for subsequent statistical analysis.
Forecast
Key features of our coastal and marine water forecasting system include multi dimensional hydrodynamic and ecological models including advanced data assimilation routines, continuous calibration and validation of model results and comprehensive and custom web based presentation of relevant metocean data. This includes now-cast, hindcast and forecast information.
