The ocean wave and current climate characterization is a backbone instrument for the Marine Renewable sector. 

The expansion of coastal HF Radar ocean observing networks worldwide together with increasing capabilities of ocean model forecasting are setting new standards in relation with oil spill trajectory confirmation and prediction.  HF Radar provides high-resolution views of the surface currents in near real-time that are valuable in providing real-time and historical data.  When combined with modeled winds and tidal analysis methods, however, HF Radar can also provide oil trajectory nowcasts and short-term forecasts.  As a consequence, marine information systems and services are increasingly including these value-added data products into response operations.

CODAR Ocean Sensors is the world leading HF Radar manufacturer having at present more than 400 operative references. CODAR SeaSonde HF radar technology is a non-contact sensor that remotely measures high quality real-time ocean currents maps and waves parameter. CODAR SeaSonde HF radar is the only proven technology that provides you with years of real-time data over large coverage areas, with ranges of up to 200 km. As a complement to SeaSonde HF Radar the PORTUS by QUALITAS marine information system provides added value tools, data fusion and other integrated products that improve the quality of the measured data and help manage and take the most out of this information.

The QUALITAS Remos range of SeaSonde centered services include all activities that are needed to provide highest quality marine information over the years and are performed following ISO 9001 and ISO 14001 procedures. Our services start with consultancy works such as detail system implementation planning and permit management, we include the equipment delivery & installation and commissioning and finally, we many times end up providing efficient HF Radar operation services over the years. The activity is carried out by a specialized experienced international team of persons that work in partnership with CODAR Ocean Sensors Ltd and the end customers applying best world practices being an active member of the world leading HF Radar technical support network that exists around SeaSonde technology.

 HF radar applications to Marine Renewables

General knowledge of the complex tidal currents of the ocean where marine renewable fields are to be installed, and how they interact with waves, is extremely limited.

The design and development of marine renewable devices requires a clear understanding of the environment and its resulting imposed loading on such structures. Marine Energy Converters (MEC) require to withstand specific environmental loadings and their moorings and foundations in turn require unique characteristics. The combination of wave and current loading is of particular importance, especially for moored tidal energy convertors (TECs) where such combinations can impose high cyclic loading. The understanding of the interactions of waves and currents is a key to identify the hydrodynamic implications of rotors for moored TECs. HF radar provides full, archived mapping, day and night ocean currents and waves data in real time.
