Chelsea Technologies Group Ltd (CTG) has announced the installation of the new version of its Sea Sentry, which will be used to monitor a newly installed SOx scrubber system on board a bulk carrier.

The CTG Sea Sentry is a wash water monitoring system which monitors both the sensor inlet and outlet of wet exhaust gas scrubber systems. It is a turnkey solution which measures polycyclic aromatic hydrocarbon fluorescence, turbidity (to ISO 7027: 1999 International Standard), temperature and pH. The system includes a touchscreen display user interface, and data is relayed to a main control system via an ethernet connection.

Sea Sentry is designed to be used by both newbuilds - 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.

To comply with International Maritime Organization (IMO) environmental regulations, shipowners and operators are 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 is used to ensure that the wash water is within acceptable limits and thus protect the environment from high levels of contamination in exhaust-gas scrubber wash water discharge.

"We have to date supplied monitoring systems globally to the marine industry's leading providers of Exhaust Gas Cleaning Systems, and are pleased to announce the recent installation of the new improved Sea Sentry on board a major bulk carrier to monitor a newly installed SOx Scrubber system," said Stephanie Lavelle, CTG's Maritime Sales Manager.

"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. This is a natural extension to our business supplying FerryBox environmental systems for commercial vessels and ships of opportunity," added Lavelle.
