OSIL’s Inshore Monitoring Buoy is a cheap, quick and easy way to ensure constant and immediate data collection when other systems are out of action, or where an environmental situation requires immediate monitoring (such as the potential release of hydrocarbons).

The buoy is designed for quick deployment in sheltered coastal and inshore areas. Its size and weight make it ideal for one person to handle in the field, and its single point mooring makes for easy deployment and recovery. These data buoys are well suited to mobile dredge plume monitoring as the buoys can be picked up and re-positioned wherever dredging activity is taking place.

Manufactured using a rotationally moulded polyethylene hull, the Inshore Monitoring Buoy is built with a central structure designed to safely accommodate sensors, such as a multiparameter sonde, turbidity sensor, or similar instrument, while providing protection from collision damage.

The Inshore Monitoring Buoy carries up to four 14W solar panels with battery back up, and a GPRS enabled data logger. Weighing 35 kg and having a total length of 1.8m, this buoy is easy to handle and deploy.
