Metocean Moorings


GEOxyz provides high precision Acoustic Doppler Current Profiler (ADCP’s) and Wave measurements for estuary, coastal and offshore applications. Acoustic Doppler devices use sound waves and the Doppler effect to measure velocity fluctuations underwater, and can do so several times per second. Currents can be measured not only close to the instrument itself, but also some distance away, as well as simultaneously at many points along the way.

Currents in rivers, estuaries or at sea are a dynamic and often unpredictable and sometimes dangerous phenomenon. GEOxyz can set out mooring posts to record and analyse the currents to determine how they would affect your project. Our models can be used to understand the environment and to design ports and their protective structures.

If you were to look at the distribution of energy for waves you would see considerable variability. A significant amount of this energy is found in the wind waves. These are the waves that engineers and scientists are primarily interested in when they study wave measurements. The local sea state is composed of waves with different amplitudes, periods and directions. Understanding this is the first step towards making accurate wave measurements.

Waves are random, and therefore measuring waves requires sampling over a period of time that will best represent the complete sea state. The resulting time series of the raw measurements is not particularly useful from a practical standpoint, and therefore needs to be processed to yield parameters that can broadly, yet accurately, characterize the sea state. The most common wave parameters describe 

Wave Height
 - The vertical distance between crest and trough. 

Wavelength - The horizontal distance between successive crests or troughs. 

Wave Period - The time it takes for one complete wave to pass a particular point. 

Wave Frequency - The number of waves that pass a particular point in a given time period.

LiDAR buoy


Our LiDAR Buoy's main mission is to measure wind with the highest accuracy possible in all weather and ocean conditions that can be encountered on an offshore wind farm to reduce the resource assessment uncertainty.

Our buoys measure wind, wave and currents parameters as well as a wide range of physical data from the marine environment.

Our buoys' design includes a standard central part and various appendices that adapts its hydrodynamic behaviour to a specific site or region of the globe. It has been designed to be transported in standard containers which simplifies its shipment to all continents by boat or truck.
