SMART ESM – Exhaust Scrubber Washwater Monitor

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.

Rivertrace is an ISO 9001 Quality-Assured Company and market leader in Oil in Water Quality Monitoring, with over 30 years’ experience and your partner to ensure that the wash water discharged from your exhaust gas cleaning systems is compliant with the global regulations on discharge.

SMART PFM 107 OIL IN WATER MONITOR

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.

Oil concentration, pressure, temperature and oil alarm status are displayed on an HD touchscreen. Oil concentrations, alarms and fault log are stored within the system to comply with the reporting requirements of IMO resolution MEPC.107(49) and can be downloaded onto a pc via LAN or USB for further analysis.

The SMART PFM 107 offers a choice of auto cleaning methods to ensure the accuracy is maintained at all times. The cleaning is fully automatic and operates whenever it senses contamination of the optical windows.

SMARTSAFE ORB (Oil Record Book)

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. This is often seen as an easy target for Port State Control and other Marine Enforcing Agencies.

In its simplest form the Smartsafe ORB will utilise the ships GPS and records the process of the bilge water discharge. The base unit documents the vessel’s time/date/latitude and longitude of the start and stop of the discharge process. The event summary is displayed on the control screen for easy viewing and is used to annotate the oil record book.

This data can be downloaded to a PC, printed or emailed using the built-in email application.

The Smartsafe ORB has sufficient memory to store three years of typical discharge records.

OPTIONAL COMPONENTS
GPS & INTERFACE MODULE : Where the ships GPS is not able to be used, in cases where there are no spare outputs for example, Rivertrace can provide a stand-alone NMEA 0183 GPS and Interface module that connects directly into the Smartsafe ORB.
FLOW METER & SECURITY CAGE : Adding a tamper proof electronic Flow Meter to the Smartsafe ORB enables the exact amount of water discharged to be measured which gives the following advantages:- Volume of actual Oil discharged overboard can be calculated and recorded utilising the PPM reading from the OCM.
SECONDARY DIVERTER VALVE & TAMPER PROOF SECURITY CAGE : To increase the overall security of the system to prevent accidental or malicious discharge or separator bypass, a secondary diverter valve with position feedback can be installed after the standard IMO diverter valve.

This secondary valve is controlled solely by the Smartsafe ORB and will immediately be closed should a malfunction or malicious act be detected.

SEPARATOR INTERFACE MODULE : In cases where the Smartsafe ORB is installed in the Engine Control Room and the signals from the OCM or Separator are not compatible, a separator interface module is required. This converts any signals from any OCM and any Oily Water Separator into a compatible signal for the Smartsafe ORB. This also enables the Smartsafe ORB to be retrofitted to any vessel irrespective of the type of equipment fitted.
PRINTER : By adding a printer to the system the summary discharge log can then be printed at the end of each discharge and attached to the manual Oil Record Book, avoiding potentially costly manual entry errors.

SMART BILGE 15PPM OIL CONTENT MONITOR

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.

APPLICATIONS

  • MEPC 107(49) Bilge Water Discharge.
  • Rig Slop Tank Discharge.
  • Air Cooler Drains Overboard Discharge.
  • Oily Water Separator Discharge.

FLOWSWITCH

The flowswitch option has been designed to ensure that bilge water is flowing through the measuring cell when in monitoring mode. An error is shown on the display if there is no flow.
The flowswitch monitors the flow of water through the cell. This ensures that the flow cannot be shut off accidentally or maliciously. In case of no flow, the Smart Bilge will close the overboard discharge valve.

AUTOCLEAN

The autoclean option has been designed to ensure that the measuring cell glasstube is kept free from fouling. Cell fouling is recognised as a leading cause of monitor malfunction. Fitting the Autoclean removes the need for the ship’s crew to remember to clean the cell manually.
