The one-time verification of the equipment should cover the following statutory requirements:
| Component |
|---|
|
Each ballast water management system (BWMS) manufactured under Coast Guard approval must have a nameplate which is securely fastened to the BWMS and plainly marked by the manufacturer |
|
Coast Guard approval number assigned to the BWMS in the certificate of approval present on the nameplate |
|
Name of the manufacturer present on the nameplate |
|
Name and model number of the BWMS present on the nameplate |
|
The manufacturer's serial number for the BWMS present on the nameplate |
|
The maximum allowable working pressure for the BWMS present on the nameplate |
|
The nameplate or lettering must be capable of withstanding the combined effects of normal wear and tear and exposure to water, salt spray, direct sunlight, heat, cold, and any substance used in the normal operation and maintenance of the BWMS without loss of readability. |
|
The nameplate must not be obscured by paint, corrosion, or other materials that would hinder readability. |
|
The BWMS allows operation to be initiated, controlled, and monitored by a single individual, with minimal interaction or attention once normal operation is initiated |
|
The BWMS meets recognized national or international standards for all related marine engineering and electrical engineering applications |
|
The BWMS Incorporates a continuous self-monitoring function during the period in which the BWMS is in operation |
|
The BWMS records proper functioning and failures of the system |
|
The BWMS records all events in which an alarm is activated for the purposes of cleaning, calibration, or repair |
|
The BWMS ss able to store data for at least 6 months and to display or print a record for official inspections as required |
|
In the event that the control and monitoring equipment is replaced, actions must be taken to ensure the data recorded prior to replacement remain available onboard for a minimum of 24 month |
|
Visual means of indicating (both on the BWMS and in a normally manned space) when the BWMS is operating, including a visual alarm activated whenever the BWMS is in operation for the purpose of cleaning, calibration, or repair. |
|
Audio and visual alarm signals in all stations from which ballast water operations are controlled in case of any failure(s) compromising the proper operation of the BWMS. |
|
Means to activate stop valves, as applicable, if the BWMS fails |
|
Suitable manual by-passes or overrides to protect the safety of the vessel and personnel in the event of an emergency. |
|
Means of automatic operation for BWMS installed in unoccupied machinery spaces, from the time placed on-line until the time secured. |
|
Any electrical equipment that is a component of the BWMS must be installed in a non-hazardous location unless certified as safe for use in a hazardous location. Any moving parts which are fitted in hazardous locations must be arranged in a manner that avoids the formation of static electricity. |
|
The OEM BWMS Manual availabe on board is the version as required by the USCG Type Approval |
|
The vessel's ballast water system must be provided with sampling ports arranged in order to collect representative samples of the vessel's ballast water. |
|
The BWMS influent sampling port is as close as practicable to the BWMS prior to treatment to determine concentrations of living organisms upon uptake |
|
The BWMS effluent sampling port is as close as practicable to the BWMS overboard outlet prior to the discharge point to determine concentrations of living organisms prior to discharge |
|
If additional sampling ports are installed they are located elsewhere as necessary to ascertain the proper functioning of the BWMS |
|
