OSIL SUPPLIES BUOY PLATFORMS TO JAN DE NUL

Ocean Scientific International Ltd. (OSIL) supplied eight buoy platforms to Jan de Nul Group platforms for environmental monitoring on dredging and renewables projects. The 1.2-meter (3.9-foot) buoy incorporates a variety of sensors with specialized seabed frames from different manufacturers including AML Oceanographic Campbell Scientific and Nortek.

OSIL said it worked closely with Jan de Nul on the design and the buoys are configured to quickly swap between Iridium UHF and GPRS telemetry methods depending on what systems are available at different locations.

Data from the buoy systems are emailed to Jan de Nul project workers. The low power telemetry solution provides a constant flow of data from the sensors while allowing remote control of measurement interval and data reporting schedules.

The buoys can be moored in a variety of water depths ranging from three to 50 meters (9.8 to 164 feet). The hull and top frame are manufactured from rotationally molded poly-ethylene with the hull being filled for added security. The top frame accommodates four solar panels a built-in radar reflector and a St. Andrews Cross that can fit a wide range of antennae light and met sensor combinations to suit requirements.
