Table 1 – List of BWTS Monitoring & Control Devices

Device Purpose

Monitoring Devices

Magnetic Flow Meter

Measures motive water flow. This is one of the parameters the PLC uses to achieve proper dosage.

Pressure Transmitter

Measures vacuum in the reactor column. This is one of the safety parameters that verify that the system is operating properly.

Ultrasonic Flow Meter

Measures ballast water flow. This is one of the parameters the PLC uses to achieve proper dosage.

ClO2 Optical Analyzer

Measures ClO2 co ncentration in the solution delivery line. This is used as verification that the system is producing the desired amount of ClO2.

Control Devices

Variable Frequency Drives

Controls the chemical dosage pumps by altering the frequency on the pumps’ power supply. These are in turn controlled by the PLC to achieve proper dosage.

Electronic & Pneumatic Valves

Segregates the BWTS from the ship’s water systems in the event of ship’s power loss.

-System (OIT) Error Codes -Alarms & Conditions -Resetting Alarms & When to Contact Ecochlor The following is a list of the Ecochlor® BWTS alarms:

Vacuum Signal: This alarm detects if the vacuum transmitter is operating properly. It can also detect a severed connection from the PLC to the instrument.

Unit Startup – Flow: Upon entering startup mode, the system is given a user settable time to reach flow conditions. If flow conditions are not met, the system will go back into a standby mode and give an alarm.

Unit Startup – Vacuum: Upon entering startup mode, the system is given a preset time to reach proper vacuum conditions. If vacuum conditions are not met, the system will go back into a standby mode and give an alarm.

Chemical Pump Fault: This alarm will shut down the unit if the pump detects a chemical pump (sulfuric acid or Purate®) fault.

Water Flow – Low: This first-level alarm is typically used as a “warning” to alert the operator that motive water flow is below optimum levels.

Water Flow – LoLo: This second-level alarm is typically used to shutdown the reactor if the motive water flow is well below optimum levels.

Vacuum – Low, –10”Hg to –5”Hg: This first-level alarm is typically used as a “warning” to alert the operator that the reactor is approaching atmospheric pressure.

Vacuum – LoLo, –3Hg: This second-level alarm shuts the system down if the reactor pressure reaches –3”Hg.

Vacuum –Decomp 25%: This alarm is used to shutdown the system when a pressure spike is detected by the pressure transmitter.

PLC Hardware Alarm: The PLC continuously monitors its status and will activate an alarm if any error is detected with the PLC hardware, not the Operator Interface Terminal (OIT).

Efficiency – Low Site specific: This alarm is OPTIONAL and can be used with an optional analyzer. It can either give a warning or shutdown the system if the calculated system efficiency is below set-point.

Efficiency – Low Average: This alarm is OPTIONAL and can be used with an optional analyzer. It can either give a warning or shutdown the system if the thirty-minute average calculated system efficiency is below set point.

Other Features:

Manual Stop The manual stop button stops the chemical feed pumps and shuts off the booster pump to the system (if booster pump control is routed through the PLC). If the button is energized, the machine will not re-enter run mode until the button is pulled out and the subsequent notice message is acknowledged. Manual stop buttons can be placed at multiple locations as needed based on the ship’s design and ballasting SOP.

Data Logging The OIT displays a complete alarm history with time/date stamping of each alarm event. Ecochlor is now designing data logging capabilities into all systems to facilitate compliance monitoring. The data that is collected can include many parameters associated with ballasting and specific ballasting events. Essentially this data is only limited by the hardware available in the ship’s systems to generate a signal to input into the data logger.
