The Maritime Safety Committee at its 92nd session adopted Resolution MSC.350(92) with amendments toSOLAS coming into force on 1 January 2015. The amendments to SOLAS Chapter V now set a clear timeschedule for the implementation of a BNWAS for ships built before 1 July 2002.
Time schedule for the required BNWAS is set as follows:
1) passenger ships irrespective of size, not later than the first survey after 1 January 2016;
2) cargo ships of 3,000 gross tonnage and upwards, not later than the first survey after 1 January 2016;
3) cargo ships of 500 gross tonnage and upwards but less than 3,000 gross tonnage, not later than thefirst survey after 1 January 2017; and
4) cargo ships of 150 gross tonnage and upwards but less than 500 gross tonnage, not later than the firstsurvey after 1 January 2018.
Administrations may exempt ships from the requirement when such ships will be taken permanently out ofservice within two years after the implementation date.
| The term “first survey” means the first annual survey, the first periodical survey or the first renewal survey whichever is due firstafter the date specified or any other survey if the Administration deems it to be reasonable and practicable, taking into account theextent of repairs and alterations being undertaken. |

Administrations may exempt ships constructed before 1 July 2002 from the requirement when such ships will be taken permanently out of service within two years after the implementation date.
The vessel is already equipped with a BNWAS. Can I use it?
According to Resolution MSC.282(86), a BNWAS installed prior to 1 July 2011 may subsequently be exempted from full compliance with the standard adopted by IMO at the discretion of the Administration. Special advice or requirements by the Flag State Administration should be observed.
Where should I install the reset push buttons?
According to the performance standard MSC.128(75), 5.1.4 reset facilities should only be available in positions on the bridge providing proper lookout. Means of activating the reset function should be easily accessible from the conning position, the workstation for navigatingand manoeuvring, the workstation for monitoring and the bridge wings.
Is it necessary to install reset facilities on the bridge wings?
Reset facilities on the bridge wings should be installed if the bridge wing is defined as a workstation, i.e. if it is possible to observe all relevant external and internal information and control the manoeuvring of the ship.
Is it necessary to connect the BNWAS to the VDR?
According to the Code on Alerts and Indicators, Resolution A.1021(26), implemented on 18 January 2010, the BNWAS first-stage audible alarm and the malfunction of, or power supply failure to, the BNWAS are classified as a mandatory alarm. The BNWAS should be connected to the VDR on ships whose keel is laid on or after 18 January 2010.
Is it necessary to connect the status “activated” from autopilot to the BNWAS?
According to Resolutions MSC.282(86) and MSC.350(92), the BNWAS should be operational whenever the ship is underway at sea. A status from the autopilot is not required. A connection to the GPS or speed log is not allowed.
May I combine the second and third stage alarm?
According to MSC.128(75), 4.1.2.6 in vessels other than passenger vessels, the second and third stage remote audible alarms may sound in all the locations mentioned in 4.1.2.4 and 4.1.2.5 at the same time. If the second stage audible alarm is sounded in this way, the third stage alarm may be omitted.
Can I use the general alarm system for sounding the third alarm?
The audible alarm for the third stage should be easily identifiable by its sound and should indicate urgency. The sound should clearly differ from the fire alarm, general alarm, etc.
