ClassNK certification for Sea Sentry wash water monitoring

The company said that this certification provides assurance to shipowners and operators that its Sea Sentry system provides accurate and robust data to demonstrate compliance with IMO Annex VI wash water discharge regulations.

“For those taking the decision to invest in scrubbers, it is critical that vessel operators work with knowledgeable experts to receive the training they need to operate new systems,” said Dr Brian Phillips, managing director of Chelsea Technologies Group.

“Achieving ClassNK certification is a significant step in our commitment to obtaining type approval for all of our monitoring systems, offering our customers the assurance that our systems meet the utmost standards in quality, accuracy and operational efficiency.”

Crucial monitoring

Dr Phillips said that whilst the payback period is relatively short, scrubbers are a costly capital expenditure and so it is crucial that compliance with environmental regulations can be proven.

All varieties of wet scrubber systems use wash water which must be monitored at all times to avoid discharges that may exceed regulations and damage the environment.

Sea Sentry provides a fully autonomous wash water monitoring system, which monitors both the water inlet and outlet of wet exhaust gas scrubber systems.

The system has the ability to accurately measure the polycyclic aromatic hydrocarbon, absorbance, turbidity (to ISO 7027: 1999), temperature and pH of scrubber washwater. It can monitor open-loop, closed-loop and hybrid scrubber systems.
