During dredging and marine engineering projects, it is often required to closely monitor the effect of the works on the environment. For example, a dredging project may be close to a coral reef, or a new port may be constructed near fish farms or pristine beaches.

Waves, currents, tide and weather are very important for all work at sea. If waves get too high or wind gets too strong, it may be necessary to interrupt a dredging project or to interrupt construction work. Knowledge of currents is necessary for maneuvering, to determine forces on constructions and to predict the spreading of fumes and pollution.

In most cases, a number of monitoring buoys and/or poles will be strategically placed at the site. These stations provide continuous monitoring of typically:

  • Water quality: conductivity, turbidity; dissolved oxygen, pH, PAR
  • Sea state: waves, current
  • Weather: wind speed & direction, visibility, temperature, humidity

Observator can deliver complete integrated monitoring systems from sensor to desktop software for managing the acquired data. These systems include sensors, power, telemetrics, buoys, platforms and processing software.
