Monitoring environmental conditions is an essential requirement for dredging operations.
OSIL offer a range of sensors (e.g. turbidity, flow), platforms (e.g. databuoys, moorings), and sampling equipment (e.g. corers, grabs) together with analytical services to provide turn-key field systems.
Increasing focus on efficiency and emergency response has lead to a greater demand for real-time monitoring of environmental factors such as waves, currents and tides. Tighter controls on pollution have placed higher demand on the quantity and quality of analyses of water and sediment, and many of these data can now be provided in real-time. Real-time marine measurements can be made available, securely, via the internet, GSM network or radio transmission. Ocean Scientific International Ltd (OSIL) has been involved in supplying a wide range of monitoring and measurement systems for ports and harbours throughout the UK, Europe and the Middle East.

Ocean Scientific International Ltd (OSIL) has been involved in supplying a wide range of monitoring and measurement systems for coastal areas throughout the UK, Europe and the Middle East.
Monitoring waves and tides can often be an essential component in maintaining safe working conditions at sea. OSIL offer a range of instruments and systems to monitor waves and tides in nearshore, coastal and offshore applications. Systems installed include real-time tidal data in ports and harbours and wave height and direction monitoring around floating oil platforms.

Ocean Scientific International Ltd (OSIL) has been involved in supplying a wide range of monitoring and measurement systems for offshore installations throughout the UK, Europe, the Middle East and West Africa.
Seabed sampling equipment includes box corers, gravity corers, piston corers and grabs. A range of multiple corers can provide samples with an undisturbed sediment/water interface and the new vibrocorer samples coarse grain sand and gravel sites. Water sampling devices include single or multiple remote operating bottles. The rectangular midwater trawl (RMT) provides an opening and closing net system for the collection of mid-water plankton and nekton.
Currents can be measured in the sea from the surface to the seabed using a range of instrumentation from OSIL. Acoustic Doppler Current Profilers (ADCP) are accurate, reliable and easy to use. Sideways looking ADCP can monitor channels as narrow as 0.5 m and as wide as 120 m from a single point source. An HF wave radar system is available from OSIL which can continuously monitor surface currents from the shore out to 200 km.
Determination of water quality in the marine environment requires specialised instrumentation. OSIL offer a range of individual sensors and systems for the measurement of hydrocarbons, pollutants, chlorophyll, salinity, dissolved oxygen, pH, redox, turbidity and nutrients. Water sampling devices are also available.
We offer a range of meteorological sensors for operation in harsh environments. Parameters measured include wind speed and direction, temperature, humidity, barometric pressure and rainfall. Digital display units and data handling can offer easy-to-read presentation of meteorological conditions from offshore and onshore locations.
Conductivity, Temperature and Depth (CTD) devices are widely used in marine scientific measurement for in-situ measurement. OSIL staff are highly experienced in this field and offer a comprehensive range of CTD products together with full service, repair and calibration facilities. Sound Velocity (SV) measurements play an important role in the calibration of sonar equipment. OSIL offers state-of-the-art sound velocimeters which provide the highest accuracy sound speed data.
Salinity is one of the most measured parameters in oceanography and is used widely in marine chemistry, physics and biology. The quality and comparability of salinity data worldwide depends largely on the widespread use of IAPSO Standard Seawater and a high precision laboratory salinometer or in situ CTD instrument.
