Chelsea Technologies Group has installed an improved version of its Sea Sentry wash water monitoring system on board a major bulk carrier, to monitor a newly installed SOx scrubber system.
The CTG Sea Sentry is described as a proven wash water monitoring system which monitors both the sensor inlet and outlet of wet exhaust gas scrubber systems.
To comply with International Maritime Organization (IMO) environmental regulations, global shipping is required to meet specific exhaust gas emission levels. One method of doing this is to clean emissions before release using an exhaust gas scrubber system. 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. The CTG Sea Sentry confirms that the wash water is within acceptable limits and thus protects the environment from high levels of contamination in exhaust-gas scrubber wash water discharge.
Sea Sentry is a turnkey solution which measures polycyclic aromatic hydrocarbon fluorescence, turbidity (to ISO 7027: 1999 International Standard), temperature and pH. A touch screen display provides a flexible user interface and data is relayed to a main control system via an ethernet connection. Sea Sentry is ideal for both new ship builds (as in the case of the recent installation on the bulk carrier) and retrofit installations. It is fully compliant with the requirements of Resolution MEPC.259(68) for exhaust gas cleaning washwater and has a Statement of Compliance from DNV GL.
“Providing water quality monitors for Exhaust Gas Cleaning Systems expands our existing capability in the supply of in-line monitoring systems to the maritime sector,” said Stephanie Lavelle. “This is a natural extension to our business supplying FerryBox environmental systems for commercial vessels and ships of opportunity.”
