Introduction: The IMO Committee approved the draft amendments to the SOLAS Regulation that requires the mandatory carriage of a bridge navigation watch alarm system for the subsequent adoption at the MSC 86. (Amendments to the SOLAS Reg. V/19 ‐ Carriage requirements for a bridge navigational watch alarm system) Background: A bridge watch alarm system is a device which triggers an alarm if an Officer on Watch (OOW) becomes incapable of performing the OOW’s duties. IMO had adopted the performance standard as MSC. 128 (75) and there are ships which have already installed the equipment on a voluntary basis. Currently, there are two types, i.e., one which requires the watch officer to press a button in an interval (if he fails to do so, it triggers the alarm), or another, which detects movements of the watch officer, using the motion sensor technology. (So far as the sensor finds movements of the watch officer the alarm will not go off). Application: The draft amendments stipulate as follows: 1st July 2011 on or after for all new builds of 150 gt or over ‐ (keel lay base) Ships constructed prior to 1st July 2011 will have to fit the BNWAS by the 1st survey after: 1st July 2012 for cargo ships of 3000 gt or over and all passenger ships. 1st July 2013 for cargo ships of 500 gt or over but less than 3000 gt. 1st July 2014 for cargo ships of between 150 gt or over but less than 500 gt. These requirements also apply to ships not engaged on international voyages. Extract from MSC128 (75) 4.1.2 Operational sequence of indications and alarms 4.1.2.1 Once operational, the alarm system should remain dormant for a period of between 3 and

12 min (Td). 4.1.2.2 At the end of this dormant period, the alarm system should initiate a visual indication on the

bridge. 4.1.2.3 If not reset, the BNWAS should additionally sound a first stage audible alarm on the bridge

15 s after the visual indication is initiated. 4.1.2.4 If not reset, the BNWAS should additionally sound a second stage remote audible alarm in

the back‐up officer’s and/or Master’s location 15 s after the first stage audible alarm is initiated.

4.1.2.5 If not reset, the BNWAS should additionally sound a third stage remote audible alarm at the locations of further crew members capable of taking corrective actions 90 s after the second stage remote audible alarm is initiated.


Page 10 of 40 Iss.1/Rev.5 09.08.10

4.1.3 Reset function 4.1.3.1 It should not be possible to initiate the reset function or cancel any audible alarm from any

device, equipment or system not physically located in areas of the bridge providing proper look out.

4.1.3.2 The reset function should, by a single operator action, cancel the visual indication and all audible alarms and initiate a further dormant period. If the reset function is activated before the end of the dormant period, the period should be re‐initiated to run for its full duration from the time of the reset.

4.1.3.3 To initiate the reset function, an input representing a single operator action by the OOW is required. This input may be generated by reset devices forming an integral part of the BNWAS or by external inputs from other equipment capable of registering physical activity and mental alertness of the OOW.

4.1.3.4 A continuous activation of any reset device should not prolong the dormant period or cause a suppression of the sequence of indications and alarms.

4.1.4 Emergency call facility

Means may be provided on the bridge to immediately activate the second, and subsequently third, stage remote audible alarms by means of an ‘Emergency Call’ push button or similar.

Indications and Operation:

Monitor and Alert Panel (MAP): Controls: RESET AND TEST Touch Pad. PUSH FOR EMERGENCY Touch Pad. Visual and Audible Indications:

• SYSTEM ACTIVE = Timer is activated. • SYSTEM FAULT = Fault detected. • BRIDGE ALERT = 1st Stage Alarm. • OFFICER ALERT = 2nd Stage Alarm. • CREW ALERT = 3rd Stage Alarm. • Audible alarm for all 3 stages of alarm. • Both ‘RESET and TEST’ and ‘PUSH for EMERGENCY’ pads are illuminated when power applied. • Night Illumination level controlled by the light sensor LDR.

Key Switch Position: OFF ‐ SYSTEM ACTIVE is off. AUTO ‐ BNWAS in standby the SYSTEM ACTIVE will lazy flash, 6 seconds on and 2 seconds off. AUTO ‐ BNWAS is active then SYSTEM ACTIVE will be permanently lit. MANUAL ‐ SYSTEM ACTIVE will be permanently lit. BRIDGE ALERT, OFFICER ALERT and CREW ALERT: These are cancelled and reset by the PIR detecting movement in the bridge area, or by pressing the RESET AND TEST pad on the Monitor and Alert Panel (MAP) or the WATCH ALERT RESET pad on the Remote Acknowledge Panel (RAP). During the dormant period pressing the RESET AND TEST pad on the MAP will briefly illuminate both the RESET pads and the BRIDGE ALERT indication to acknowledge the action. Pressing the WATCH ALERT RESET pad on the RAP has the same result. EMERGENCY CALL: Press and hold the PUSH FOR EMERGENCY pad for a minimum of 1.5 seconds. This will initiate the alarm sequence at the OFFICER ALERT stage but disables the PIR, and then proceeding as per the normal time line sequence. Note! That only by pressing the RESET AND TEST pad on the MAP or the WATCH ALERT RESET pad on the RAP will cancel the emergency call as the PIR will have been disabled. BRIDGE ALERT TEST: Press the RESET AND TEST pad for a minimum of 1.5 seconds. The BRIDGE ALERT is initiated for as long as the touch pad is held pressed. SYSTEM ACTIVE & SYSTEM FAULT indications are also lit. The OFFICER ALERT and CREW ALERT are temporarily disabled to prevent any alarm off the bridge.

LDR


Page 12 of 40 Iss.1/Rev.5 09.08.10

Remote Alert Panel (RAP): Controls: WATCH ALERT RESET Touch Pad. Visual and Audible Indications:

• WATCH ALERT RESET pad is dimly illuminated when power applied.

• Visual indication for all 3 stages. • Audible alarm for all 3 stages of alarm. • Night Illumination level controlled by light

sensor LDR on the MAP. BRIDGE ALERT, OFFICER ALERT and CREW ALERT: These can also be acknowledged and reset by pressing the WATCH ALERT RESET pad on the RAP. During the dormant period pressing the WATCH ALERT RESET pad on the RAP will briefly illuminate WATCH ALERT RESET pad to acknowledge the action. Watch Alert Panel (WAP) 2nd & 3rd Stage Alarms: Controls: None Visual and Audible Indications Only:

• SYSTEM ACTIVE = Timer is activated. • WATCH ALERT = 2nd or 3rd Stage Watch Alarm. • Audible alarm for 2nd or 3rd Stage Watch Alarm.

WATCH ALERT: This can only be acknowledged and reset by attending the bridge and pressing the RESET AND TEST pad on the Monitor and Alert Panel (MAP) or the WATCH ALERT RESET pad on the RAP.

Operation:

Once the MEU has been configured the cover and padlock in place the Captain is to switch the system into the required MODE and remove both the padlock and MODE selection keys and keep them in a secure place to prevent any unauthorised changes or tampering. ALERT sequence without Acknowledgements: Once operational, the Bridge Navigational Watch Alarm System (BNWAS) will remain dormant for a period of between 3 and 12 min (Td). At the end of this dormant period (Td), the BNWAS will initiate a visual indication only on the bridge i.e. the RESET AND TEST pad and the BRIDGE ALERT indication will flash on and off for 15 seconds. If within this 15 second period (Td +15sec) the BNWAS is not acknowledged, the system will additionally sound the 1st stage audible alarm on the bridge only for a further 15 seconds.

If the 1st stage alarm is not acknowledged (Td +30sec), the BNWAS will advance to the 2nd stage remote alarm condition where the OFFICER ALERT/WATCH ALERT which is an audible and visual alarm in the designated Officer’s and/or Master’s location. If the 2nd stage alarm is not acknowledged (Td +120/210sec), the BNWAS will advance further and go into the 3rd stage remote alarm condition where the CREW ALERT/WATCH ALERT which is an audible and visual alarm at locations where crew members can be alerted to take corrective actions. If the 3rd stage alarm is not acknowledged (Td +240/420sec), the BNWAS will advance further and go into the 4th stage remote alarm condition where there is a Dry Contact Closure which can be used to activate the SSAS, send an Email through the S.E.A.S. or put the engine into safe mode.

UNACKNOWLEDGED ALARM TRANSFER sequence: BNWAS detects an UNACKNOWLEDGED alarm, and ENABLEs the TRANSFER. When an unacknowledged alarm arrives and is transferred, the EMERGENCY Call is immediately initiated and the system goes straight into the alarm sequence at the 2nd stage or the OFFICER ALERT (Td +30sec). Pressing a BNWAS RESET touch pad on the MAP or RAP clears the emergency request mutes the audible alarm & disables further transfers. This disabling is necessary to prevent triggering the emergency call whilst the bridge is manned. The BRIDGE ALERT on the MAP and RAP will continue to give the visible alert until all alarms are acknowledged at their source equipment. If a new unacknowledged alarm arrives whilst transfer is disabled the new alarm will not trigger a new BNWAS audible alert as a member of the ships staff is/are in attendance on the bridge. In the event of the NMEA data flow stopping by the source equipment being switched off a timeout of 32 seconds is used to clear that particular alarm status.

Unacknowledged Alarm Transfer Interface A.T.I.

NMEA Alarm The BNWAS A.T.I. on receiving an $--ALR,,,,V, sentence will initiate the alarm sequence at the OFFICER ALERT stage then proceeding as per the normal time line sequence.

ALR ‐ Set Alarm State Local alarm condition and status. This sentence is used to report an alarm condition on a device and its current state of acknowledgment.

Time of alarm condition change, UTC

Acknowledging the alarm at the offending equipment will change the Unacknowledged field in the $--ALR,,,,A, sentence and once received the BNWAS will reset. After 32 seconds the BNWAS will also reset if the ALR message times out.

Acknowledging the unacknowledged alarm at the BNWAS will mute the audio alarm and step back from the OFFICER ALERT to a silent BRIDGE ALERT. When the $--ALR,,,,A, sentence is received or the ALR message times out after 32 seconds the BNWAS will reset. Dry Contact Alarms The BNWAS A.T.I. on receiving an alarm signal will also initiate the alarm sequence at the OFFICER ALERT stage then proceeding as per the normal time line sequence.

BNWAS detects an UNACKNOWLEDGED alarm, and ENABLEs TRANSFER. When an unacknowledged alarm arrives and is transferred, the EMERGENCY Call is immediately initiated and the system goes strait to the 2nd stage OFFICER ALERT. Pressing a BNWAS RESET touch pad on the MAP or RAP clears the emergency request mutes the audible alarm & disables further transfers. This disabling is necessary to prevent triggering the emergency call whilst the bridge is manned.

The BRIDGE ALERT on the MAP and RAP will continue to give the visible alert until all alarms are acknowledged at their source equipment. If a new unacknowledged alarm arrives whilst transfer is disabled the new alarm will not trigger a new BNWAS audible alert as a member of the ships staff is/are in attendance on the bridge.

In the event of the NMEA data flow stopping by the source equipment being switched off a timeout of 32 seconds is used to clear that particular alarm status.


Page 24 of 40 Iss.1/Rev.5 09.08.10

NOTE! ONLY at the source (an ARPA for instance) can an unacknowledged alarm be acknowledged. Any source MUST have its own facility to: Output the unacknowledged‐alarm by ALR message or contact closure. Output acknowledgement with a new ALR message or by opening its contacts. AP unacknowledged alarm ALR data may be input via the AP port. Concerning the unacknowledged‐alarm transfer interface: By default the A.T.I. is always fitted and the data input port SK7 on the MEU must not be used. GPS data is input on port DATA 1 of the A.T.I. It is conceived that some existing equipment would have an instant‐alarm output but no provision for a delayed unacknowledged‐alarm output. That is, the contacts close the instant the equipment generates an audible alarm , and if connected to the A.T.I. then the BNWAS would give a most undesirable immediate 2nd stage OFFICER ALERT not giving the Officer On Watch to investigate the cause of the alarm. The KW909‐FM Alarm Transfer Interface can be programmed to provide a 30 second delay to any channel by pre programming the EPROM, and so give the OOW time to investigate and acknowledge the alarm.


Page 25 of 40 Iss.1/Rev.5 09.08.10

Fault Conditions: System is in STBY when the ship is in Motion: If the system is in standby mode and

• A speed above 3 knots from the GPS is detected. • Or the Autopilot is energised (Active $‐‐HTC or HTD message). • Or the autopilot is indicated to be active at “Autopilot active” input port the alarm sequence

is to be initiated.

PIR Fault: Under normal operational conditions the PIR will keep the system in a non alarm condition. Should any of the PIR fail or there is a break in the cable, after 20 minutes will cause the system to give a SYSTEM FAULT. Loss of SOG from the GPS: If the system is in Automatic mode and the SOG is enabled the loss of the $GPVTG data will after 20 minutes cause the system to give a SYSTEM FAULT. RESET Touch Pads: If any of the RESET touch pads are constantly closed or shorted then after a 20 minute period the alarm sequence will be initiated. Low Battery and Loss of AC: The BNWAS is powered by the ships main power supply. The system is battery backed and in the event of a power loss will indicate a SYSTEM FAULT and will also maintain the EMERGENCY CALL facility for a minimum of 6 hours. Wire Security Loop: If the Wire Security Loop is cut to remove the padlock the BNWAS will initiate a SYSTEM FAULT and also tag the Tamper field in the NMEA sentence for VDR recording.
