Significant Dredge Monitoring Network for OSIL

Leading global environmental monitoring systems manufacturer Ocean Scientific International Ltd (OSIL) has been awarded a significant contract for the international supply of a network of dredge monitoring buoys.

 

OSIL’s reputation for providing cost effective, proven data buoy systems on time and within budget was a significant factor in the award.  Other contributing factors included the ability to feed the data from the buoy directly into the client servers via Iridium Short Burst Data (SBD), and the ability to use the clients existing sensors to help minimise costs.

 

The Tern buoy hull design incorporates a stainless steel sub frame with a moon pool for instrument protection, and its modular manufacture makes the buoy easy to ship and assemble on-site following delivery. The twelve buoys are set up to communicate via Iridium SBD with an onboard GSM option to further reduce operational costs when the buoys are moved closer inshore as the project progresses.

 

These buoys will join a large number of existing OSIL dredge monitoring networks, with well in excess of 500 data buoy systems now installed worldwide. The OSIL buoys have proved highly successful due to their robust nature and small, manoeuvrable size enabling dredging operators to follow the dredge plume as the works progress.

OSIL buoy for EU-funded coastal erosion project

Global marine systems manufacturer Ocean Scientific International Ltd (OSIL) have supplied a  data buoy platform to the “ORION” joint research and development centre for use as a real-time monitoring station on an EU-funded project managing coastal erosion.

 

The Harmonized Coastal Corrosion Management Framework for Enhancing the Implementation of the Integrated Coastal Zone Management Protocol (HERMES) project required a platform with the ability to record a full profile of water column currents, tidal variations, wave parameters (significant wave height, wave period & propagation direction) & estimated suspended particulate matter (SPM) concentrations, with the data transmitted to a base station on land in real time, complete with software to analyse and process the data with a graphical display.

 

The OSIL Tern buoy offers a high visibility platform with a GPRS communication system ideally suited to the installation location given the proximity to the shore and a popular wreck diving site. The robust buoy is equipped with a seabed mounted Nortek AWAC to provide three-dimensional current profiles in cells with thicknesses from 0.25 to 4m. The ADCP is additionally furnished with a Prolog board for internal wave processing, and it can also be used to estimate suspended sediment loads by correlating the acoustic back scatter intensity to a site specific suspended sediment calibration.

 

The base station software provided by OSIL gives the end users extensive control over the data displayed from the monitoring buoy, highlighting OSIL’s ability to tailor individual buoy systems to meet specific project requirements.
