Rivertrace Ltd products

By utilising the “Smart Cell” Detector Array Technology, developed by Rivertrace, the OCM analyses all three oil types (HFO, Diesel and Emulsions) simultaneously without the need for re-calibration. A manual cell cleaning device is included as standard to easily enable routine maintenance. Optical cell fouling is recognised as a leading cause of monitor malfunction or incorrect reading. By simple operation of the manual cleaning device, the “Smart Cell” remains in optimum operating condition. Replacement calibrated measuring cells can be purchased for easy change over on board the vessel and calibration check kits enable the crew to demonstrate the monitor is within factory calibration to PSC Surveyors. The Smart Cell Bilge Alarm is readily available as a 5ppm version if required. It can also be tailor made for Hazardous Environments (Zone 1 & 2) as an Exd system with Auto Clean, all enclosed in an explosion proof cabinet.

The SmartSafe ORB (oil record book) Bilge overboard Security System was developed in response to our customers` worldwide requests and requirements. This system records the oily water discharge process of any Oil Water Separator (IMO - MEPC 60.33 or 107.49) thus avoiding the common mistakes of manual entries and log variations in the oil record book. These errors are an easy target for Port State Control and other Marine Enforcing Agencies.

The Oil Discharge Monitoring Equipment (Smart ODME) has been designed to provide means of monitoring, recording and controlling the ballast discharge for crude oil, product and chemical tankers including ICE class vessels. This system is modular in construction and does not require the usual pump/motor bulkhead penetration as used on older systems. The Smart ODME includes all components required to meet MEPC 108(49) and the latest MEPC 240(65) for Bio Fuels, effective 1 January 2016. The Smart ODME incorporates a ‘simulation mode’ to aid system demonstration to PSC surveyors, is designed for ease of retrofitting, operation, installation and maintenance. Discharge limits are set at 30 litres of Oil per nautical mile or 1 / 30,000 of the previous cargo for slop and wash water discharges.

With the IMO’s 2020 global sulphur cap fast approaching, a popular solution to ensure compliance is to install an exhaust gas cleaning system (EGCS). For this, wet scrubber systems use wash water to remove the pollutants from the exhaust gas. Therefore the wash water being discharged must be monitored at all times to ensure it is within the limits set by the regulating body. There are IMO regulations for water quality parameters including Polycyclic Aromatic Hydrocarbons (PAHs), pH and turbidity prior to discharge into the ocean.

Principle of Operation: The monitor measures particulates in the sample stream on a continuous basis by passing the process fluid through a proprietary photo optical measuring cell developed by Rivertrace. Using a combination of optical recognition algorithms and light intensity it is possible to differentiate between Oil particles, Gas/Air Bubbles and Solid particulates in the range 1-500 microns. Flow and particulate characteristics can be visualised live via the 7” display.

The “OCD Xtra” combines multiple light wavelengths with multiple sensor technology, to measure oil accurately in the range 0-200 ppm, even in the blackest of produced water. Multiple oil types are automatically compensated for by sophisticated algorithms. The multi – parameter display shows the sample’s oil content, pressure and a graphical average of the last 4 hours oil readings. The last 7 days readings are stored in ROM and can be accessed from the help menu. The OCD Xtra has the ability to adjust the calibration settings against laboratory analysis on site. Full on screen help is available to guide the operator during set-up and maintenance routines.

By utilising the “Smart Cell” Detector Array Technology, developed by Rivertrace, the monitor accurately analyses the quality of the sample stream and outputs the turbidity value in nephelometer turbidity units (NTU) Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles. A manual cell cleaning device is included as standard to easily enable routine maintenance and prevent Optical cell fouling which is recognised as a leading cause of monitor malfunction or incorrect reading. By simple operation of the manual cleaning device, the measuring cell remains in optimum operating condition.

The OCD CW is a low cost solution for simple cooling water monitoring applications, designed for monitoring engine cooling water and fresh water systems. The system is widely used in refineries and power stations when discharging their cooling water to local rivers and the sea. Boiler condensate can also be monitored with the addition of a cooler. With solids discrimination up to 50ppm the OCD CW provides repeatable accurate monitoring and can also be used in industrial waste water applications.

The working principle is a capacitive measurement operating on absorption of water in oil. The physical measured value is % Humidity. New oil has the ability to hold a certain amount of dissolved water. The maximum water amount oil can hold is called “saturation point”. Above the “saturation point” free water will fall out which can cause corrosion inside of the engine. The “saturation point” is influenced by temperature and other different factors like the composition of oil mineral or synthetic, formulation of additives and will change during the lifetime of the oil. The Water in Oil Sensor (WiO) is not measuring free water or emulsion, which is detectable by regular Water in Oil test kits, it measures the absolute water content in oil.
