SEAWATCH Metocean Buoys and Sensors

The SEAWATCH Wind Lidar Buoy represents the next generation of multi-purpose buoys tailored for the renewable energy industry. The buoy accurately measures the speed and direction of wind across the diameter of wind turbine rotors, whilst sensors record oceanographic parameters such as ocean waves and current profiles. 

Applications

The SEAWATCH Wind Lidar Buoy is a cost-efficient way to measure wind data at heights of conventional offshore wind turbines for wind resource assessments and engineering design criteria.

• Collects data for wind resource assessments and/or for engineering design criteria
• Ocean wave height and direction
• Ocean current profiles from the surface to the seabed
• Meteorological parameters
• Measurement of other oceanographic parameters

The SEAWATCH Wavescan buoy is a versatile instrumentation platform ideally suited for the collection and measurement of oceanographic, meteorological (metocean) and water quality data. Designed to provide less drag and large buoyancy, the Wavescan Buoy is suitable for severe environmental conditions, large water depth and remote locations or areas with strong current forces. It’s innovative “wells” for subsea sensor mounting, ensure easy servicing and maintenance.

Applications

• Offshore design and operations
• Meteorological and climatological studies
• Suitable for deepwater operations
• Harbour monitoring
• Coastal engineering
• Scientific studies
• Wave energy studies
• Maritime traffic control
• Water quality control studies

The SEAWATCH Midi 185 is a medium size discus shaped general purpose monitoring buoy suitable for measuring oceanographic and meteorological (metocean) parameters in harbours, lakes, reservoirs and coastal areas. The Seawatch Midi can be used as a marking/navigation buoy, consisting of high visibility red, green or yellow lights as per IALA recommendations, or as link station providing power/communication to subsea modules.

Applications

• Harbour and coastal monitoring
• Monitoring estuaries and large rivers
• Lake/reservoir monitoring
• Offshore design and operations
• Wave energy studies
• Maritime traffic
• Water quality studies

The SEAWATCH buoy is a multi-sensor data buoy capable of measuring wave height and direction, ocean current speed and direction, meteorological parameters, sea surface temperature, salinity and temperature and salinity profiles. The buoy is vertically stabilised giving low pitch/roll motions and is ideal for making current, wind and ocean wave measurements.

Applications

• Harbour and coastal monitoring
• Water quality control studies
• Wave and wind energy studies
• Meteorological and climatological studies
• Coastal engineering
• Maritime traffic control
• Scientific studies
• Offshore design and operations

The SEAWATCH Mini II buoy is a robust, economical and flexible buoy that measures a range of oceanographic parameters for harbours and coastal areas.

Applications

• Harbour and coastal monitoring
• Coastal engineering
• Offshore design and operations
• Scientific studies
• Wave energy studies
• Maritime traffic control

The SEAWATCH Deep Sea Module (SDSM) is designed specifically for the detection of tsunamis and can be fitted to existing SEAWATCH systems or be an integrated part of new systems.

The SDSM consisting of a pressure sensor, a processor, batteries and an acoustic modem, is located on the seafloor. The SDSM is mounted to a bottom anchor using an acoustic release. This enables easy recovery of the unit when the batteries are drained after approximately one year of operation. The SDSM is released for retrieval by the acoustic release.

The Fugro Wavesense is an Inertial Sensor that measures the motion of a buoy floating on the ocean surface. The outputs of the sensor are a time series of 3-dimensional buoy motion and wave parameters like height, period and direction along with a number of other parameters. The sensor is integrated with our datalogger GENI 3 and can therefore be directly interfaced to a number of sensors and communication devices.

The GENI 3 is a robust data acquisition unit for operation in remote locations. Powered only by batteries, it features a high-end 32-bit processor, large internal storage capacity and a proven operating system and modular C++ application software to ensure software reliability.
