Underwater Navigation

Xylem is able to supply several forms of Electronic Navigation including AIS, Radar Beacons (RACON) and many forms of remote monitoring systems. AIS is becoming increasingly popular as it not only provides an electronic position report it can also provide monitoring data and can also transmit weather and hydrological data.


Systems may include sensors and equipment such as:

Meteorological measurements

  • Wind
  • Air temperature
  • Air pressure
  • Visibility
  • Precipitation
  • Relative humidity

Oceanographic measurements

  • Current speed & direction in many layers
  • Water level
  • Significant wave hight
  • Wide range of parameters available


  • Vented tide sensor
  • Oxygen sensor
  • Pressure sensors
  • Doppler current sensor (DCS)
  • Temperature sensor
  • Turbidity sensor

Data buoy

  • Wind
  • Air temperature
  • Air Pressure
  • Visibility
  • Precipitation
  • Relative humidity

SmartGuard datalogger

  • LAN, serial and USB via cable, AIS, VHF, GPRS
  • Aanderaa sensors
  • Most 3rd party sensors
  • Metadata stored and transmitted allowing full traceability

Safe Navigation

  • Current speed and direction in multiple depths from surface to seabed.
  • Continuous monitoring of vital parameters at sea and in air.
  • Real-time sea and air parameters are distributed by the AIS system.
  • Secure docking and improved cargo handling.
  • All information available in one real-time web display application.

Environmental Monitoring

  • Sediment movement and dredging planning.
  • Monitor ocean health and oxygen concentration.
  • Expandable platform for additional environmental parameters.
  • Data stored in SQL database for further analysis.
  • Dynamic tracking of oil spill pollution.
  • Critical information to stakeholders after natural disasters or accidents at sea.

Improve Port Efficiency

  • Provide Harbour Master with a complete real-time overview of conditions affecting traffic.
  • Historical data is valuable for research, science discharge permitting.
  • Full control of vital parameters when loading/unloading to achieve max efficiency.
  • Lower insurance cost against environmental, docking and operation damage.
  • Proof and documentation in insurance claims.
