Mooring-Free Buoy



Mooring-Free Buoy

OSIL are offering a low cost re-locatable solution as an alternative to moored buoy systems for a diverse range of applications, including oil and gas projects, dredge monitoring, and environmental monitoring.

Incorporating a variety of instrumentation including a turbidity sensor, an ADCP, or a multiparameter sonde (that can be equipped with a range of sensors including DO, pH, hydrocarbons, etc.), the mobile buoy system can be programmed to keep station, patrol a specific area, or to follow a vessel (i.e. Dredgers) using state-of-the-art GPS technology.

Data can be relayed to a base station on land or on-board a vessel via GSM/GPRS, radio or satellite, and can also be set up to relay data to a live website to allow multiple users access.

Station-keeping algorithms allow the user to set the allowable radius of drift from the desired co-ordinate, or to specify a path or route for the buoy to follow, enabling users to, for example, equip a dredger with its own easily deployable, re-locatable, dredge monitoring system, that reports data in real time.
