OSIL Water Quality Monitoring (Shearwater) Buoy 1.2m



OSIL’s Shearwater Buoy is a versatile instrumentation platform ideally suited for collection and measurement of oceanographic, meteorological (metocean) and water quality data parameters in inshore coastal areas, harbours and estuaries.

 

Instrumentation can be deployed anywhere from near surface to the seabed, and the Shearwater Buoys can be used as permanent or temporary platform. The buoys can be moored in a fixed position with either single point, dual point or compliant mooring (where required).

 

The system is supplied with a range of sensors that can specified by the customer. All buoys are fitted with solar panels, navigation/warning lights and other markings as necessary. A range of telemetry options are available (UHF/VHF, GSM, GPRS, Satellite), selected to suit both the location and application requirements. OSIL provide a complete data telemetry solution, including either desk top or web-based software packages to access the data.   


The buoys are 1.2 m in diameter, with a total buoyancy of 500 kg, and have a reserve buoyancy of 300 kg after fitting the equipment such as solar panels, battery packs and monitoring instrumentation, etc.

 

The OSIL range of buoys are manufactured using rotationally moulded polyethylene hulls, which are foam filled for added security. The hulls are constructed around a galvanised steel central structure, which has a large hole through the centre which allows the passage of instrumentation and cables from the tower down through the water column to the seabed. By  utilising a 'Moon Pool', instrumentation in the centre of the buoy is well protected from damage during deployment and operation.
