SCRUBBER WASHWATER MONITOR CERTIFIED BY DNV GL

Thursday, January 16, 2020 

UK-based water quality monitoring technology company Rivertrace has received a statement of compliance from DNV GL for its Smart ESM exhaust scrubber washwater monitor.

The system monitors the washwater from wet scrubber systems used to remove pollutants from ships’ exhaust gas in order to ensure it meets IMO regulations for water quality parameters prior to discharge to the ocean.

Rivertrace’s Smart ESM, already used onboard several vessels, measures and records the regulated water quality parameters PAH, turbidity, temperature and pH, on open-loop, closed-loop and hybrid scrubber systems. The system enables ship operators to monitor washwater water quality parameters in real time at both the inlet and outlet, supporting continuous compliance within IMO washwater discharge limits.

The newly received DNV GL statement of compliance certifies that the monitoring system operates with an acceptable accuracy for measurement of the various parameters within the ranges required by MEPC 259(68). This, says the company, offers further assurance to scrubber manufacturers and the wider industry that the Smart ESM is reliable, robust and provides accurate monitoring of washwater while a scrubber is in operation. The certification indicates that ships operating scrubbers are monitoring their washwater in line with regulatory limits, ensuring that washwater constituents discharged to the ocean are within strict regulatory limits as to not damage the marine environment.

Mike Coomber, Rivertrace MD, said: “We welcome this latest stamp of approval from DNV GL for our SMART ESM technology. It further demonstrates our commitment to providing reputable equipment for washwater monitoring that ship operators can use in their quest for clean shipping. Rivertrace’s long history in the market and expertise in Oil in Water Quality Monitoring means that our customers can rest assured that our technology is well certified, fit for purpose and will provide ultimate monitoring accuracy.”
