Leading experts in the production and supply of marine environmental monitoring systems Ocean Scientific International Ltd (OSIL) offer a wide range of adaptable dredge monitoring solutions to suit all budgets and application requirements, and have over 500 data buoy systems installed globally.

OSIL have a well-established reputation for providing cost effective, proven monitoring systems on time and within budget, and produce a full range of Dredge Monitoring equipment, including re-positionable and permanently moored buoys from 0.3m and upwards, standalone monitoring stations, water quality sampling and monitoring equipment, and analysis services. Manoeuvrable data buoy systems provide dredge operators with the added advantage of the ability to follow the dredge plume as works progress.


The basic buoy hull designs incorporate a stainless-steel sub frame with a moon pool for instrument protection, with a robust modular construction that facilitates shipping and ship and assembly on-site following delivery.

Data can be relayed directly from the monitoring platforms onto client’s servers using the most suitable telemetry systems available (which can include multiple/dual telemetry systems), and OSIL regularly integrate client’s existing sensors to further minimise costs.


OSIL have produced a large number of dredge monitoring networks for an extensive global customer base and are continually adapting and innovating not only product designs, but also customer support to ensure they can continue to provide the same high quality assistance with remote setup, video-based commissioning and online troubleshooting in support of installed systems.
