Wave & current buoys

TRIAXYS Buoy

Measuring waves and currents is an important field of study for a variety of applications, including safe and secure waterway navigation, offshore renewable energy, weather forecasting, and scientific research.

TRIAXYS™ Directional Wave Buoy

The TRIAXYS™ Directional Wave Buoy is a precision instrument incorporating advanced technologies that make it an easy to use, reliable and rugged buoy for accurate measurement of directional waves.

  • TRIAXYS-Directional-Wave-Buoy1The TRIAXYS™ sensor unit is comprised of three accelerometers, three rate gyros, a fluxgate compass, and the proprietary TRIAXYS™ Processor.
  • The TRIAXYS™ provides continuous wave sampling, support for any telemetry, up to 10 Hz motion sampling and up to 32GB (>5 years) of data logging capacity.
  • The TRIAXYS™ Sensor also uses the WatchMan500™ controller, which is the core technology used in other AXYS monitoring systems.
  • The TRIAXYS™ Directional Wave Buoy is solar powered.
  • The TRIAXYS™ is easy to handle during deployment and can be rolled off a ship deck without any concern for sensor damage due to spinning.
  • The TRIAXYS™ can also withstand extreme temperatures as its sensor is not subject to freezing.
  • The TRIAXYS wave buoy can be configured with AIS Aid to Navigation to broadcast buoy position and weather information to local vessel traffic
  • TRIAXYS™ buoys have been deployed in waters from 10 to 300 meters.
  • Standard mooring configurations specially designed for wave buoys are available for water depths up to 300m.

TRIAXYS™ with Currents Buoy

The TRIAXYS™ with Currents Buoy measures both directional waves and a 3D water column profile of ocean currents in real time. The buoy is based on the proven TRIAXYS™ Directional Wave buoy platform, but has been modified to allow the integration of a current profiler in a downward facing configuration.

  • Uses custom Nortek Aquadopp & Teledyne RDI Workhorse ADCP’s and has a modular design allowing for ADCP swapping and easy replacement
  • The ADCP provides current speed & direction from user configurable sample periods in up to 128 layers of the water column
  • Provides continuous wave sampling, support for any telemetry, up to 10 Hz motion sampling and up to 32GB (>5 years) of data logging capacity.
  • The WatchMan500 processor integrates sensor systems and provides onboard data processing, data logging, telemetry, and diagnostic/set up routines.
  • Power is derived from 4 rechargeable batteries connected to solar panels
  • Standard mooring configurations specially designed for wave and current buoys are available for water depths up to 300m.
  • A variety of telemetry options are available, including UHF/VHF, Inmarsat IsatData Pro, Iridium and HSPA Cellular.
  • Can be configured with AIS Aid to Navigation to broadcast buoy position and weather information to local vessel traffic

TRIAXYS™ Mini Directional Wave Buoy

The TRIAXYS™ Mini Directional Wave Buoy is a precision instrument incorporating advanced technologies that make it an easy to use, rugged, and economical buoy for accurate measurement of directional waves. This small (0.6m diameter) and lightweight (60kg) buoy is easily deployed by two people from virtually any size of vessel.

  • TRIAXYS-Mini-Buoy.jpgProvides continuous wave sampling, support for any telemetry, up to 10 Hz motion sampling and up to 32GB (>5 years) of data logging capacity.
  • Uses TRIAXYS™ Next Wave II sensor, comprised of three accelerometers, three rate gyros, a fluxgate compass, and the proprietary TRIAXYS™ Processor.
  • The WatchMan500™ payload integrates sensor systems and provides onboard data processing, data logging, telemetry, and diagnostic/set up routines.
  • Wave and sea surface temperature data are collected, processed and logged on the buoy and then transmitted via telemetry to a base station hosting AXYS Data Management System software.
  • Standard mooring configurations specially designed for wave buoys are available for water depths greater than 150m.
  • A variety of telemetry options are available, including UHF/VHF, Inmarsat IsatData Pro, Iridium and GPRS/HSPA.
