101
•
The operator is able to control all BWTS functions through a single control unit;
•
The control unit automatically monitors and adjusts optimal treatment dosages or
intensities, or other aspects of the BWTS, and/or provides control signals to the ballast
water system of the vessel to properly provide the necessary treatment;
•
The control unit provides a continuous self-monitoring function when the BWTS is in
operation;
•
The control unit includes a tamper-proof or tamper-evident recording device, located in a
position easily accessible to the person in charge of the BWTS, that provides the operator
the parameters listed below during ballast water treatment while continuously logging the
data:
o
Proper functioning and status of all the services needed for the operation of the
BWTS;
o
All parameters necessary to ensure the proper operation of the BWTS;
o
Status of the valves present in the BWTS, including those leading to overboard
discharge;
o
Total quantity of ballast water treated;
o
Ballast water treatment rates;
o
Alarm conditions;
o
Date and time of start and end of the treatment operation;
o
Ballast operation monitored (upload, discharge);
o
Calibration and maintenance events;
o
Other system events of interest;
o
Relevant and necessary measurement information required for control and
monitoring operation of the BWTS;
o
Meter and sensor accuracy to measure the suite of parameters appropriate and
necessary for control of the BWTS, representing the actual value of the
parameters being monitored within 10% despite the presence of contaminants
normally expected in ballast water and the operational environment of the BWTS;
o
Diagnostics to enable the local operator to check the functioning of the electrical
and electronic circuitry, as well as the calibration of meters and sensors according
to the manufacturer’s specifications;
o
An emergency manual override function to be used in the event of failure of the
control unit;
o
Audio and visual alarms and a recording in the event there is discharge of any
effluent or a component failure whenever the control unit is not fully operational;
and
o
The capability to print reports and logged data, as applicable, or stored
electronically with printout capability, upon the following events:
§
The BWTS is started
§
The BWTS is stopped
§
An alarm condition develops
§
Normal conditions are restored
§
Manual override is engaged
