Sailbuoy ASV Platform with Aanderaa Smart Sensor Suite

By utilizing the power of the Aanderaa Smart Sensor Suite and the wind and solar driven "Sailbuoy" from Offshore Sensing, a new cost-efficient easily handled autonomous platform has been developed. The Sail buoy Water Quality Monitor (WQM) is designed for easy handling during shipment, deployment, data collection and recovery. The Sailbuoy WQM has been extensively field-tested and demonstrated excellent long-term monitoring.

Sailbuoy ASV Platform with Aanderaa Smart Sensor SuiteOne of the more innovative examples of an Autonomous Surface Vessel is the robust and simple to operate "Sailbuoy". Able to navigate the open ocean, the Sailbuoy operates on wind and solar energy meaning it's capable of several months self-sustained exploration. The vessel uses satellite communication for remote programming and data review.

Xylem has partnered with Offshore Sensing to offer a range of sensors for the Sail buoy platform.

  • Easy to deploy – requires no crane
  • Requires very little training to pilot
  • Long-term stability
  • Low total cost of ownership – no yearly cost beyond data transmission costs

Sensor Payload

  • The Sailbuoy features the latest in sensor technology and antifouling
  • Oxygen is monitored with the world-leading Oxygen Optode from Aanderaa complete with multi-point calibration for 1.5% accuracy
  • Aanderaa pCO2 Optode, the smallest, most low power CO2 sensor available for ocean research is used
  • Conductivity, temperature, turbidity, and chlorophyll smart sensors can be mounted depending on need

Aanderaa Oxygen Optodes

The AADI Oxygen optode was the first and only to measure dissolved oxygen for years without drift - now it is one of the fastest!
The Oxygen optode is designed to measure absolute oxygen concentration and % saturation. The optode can be used from streams to deep sea, from fish farms to waste water and from polar ice areas to hydrothermal vents. The lifetime-based luminescence quenching principle offers the following benefits

Aanderaa Conductivity Sensor

Real-time integrated calculation of salinity, density and sound of speed
Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring the electrical conductivity of seawater. Conductivity is a key parameter for in-situ measurements of several fundamental physical properties of seawater.

Aanderaa Turbidity Sensor

Detects infra-red light scattered by particles suspended in water
This measurement is known to have a good correlation to the amount of suspended matter in water and can be used to monitor e.g. sediment, algae or particle pollution. The sensor generates an output voltage proportional to the turbidity or suspended solids. The low power consumption makes it ideal for applications where battery drain is a concern.
