BNWAS Class/Flag Requirements

 Quite often the regulations coming out of the IMO are open to interpretations and in these cases the different classification societies may view the regulations in slightly different ways. Having more than one variation of the rules can be very confusing, especially if not all of your fleet are classed with the same society.

The table below shows you information on each of the classification societies and the rules which they apply to their Type Approvals.

LR accepts the use of reset arrangements based on the detection of movement for vessels where Flag Administrations accept the use of them.  

However, LR does not accept the use of reset arrangements based on the detection of movement for vessels with the additional optional ‘NAV1’ or ‘IBS’ class notations.

ClassNK does not issue a Type Approval of its own. 

However, they do accept a Type Approval certificate issued by the Authorities and Flag States and also accepts MED certificate as an equivalent of the Authorities.

 Flag Authority Requirements

 

Flag Authority Key Information
Bahamas Maritime Authority (BMA)

The BMA stance on PIR as a reset method for BNWAS had previously been that they were not acceptable.

However following a review of the performance standards of Intelligent PIR and review of IMO NAV 55/20/2 and 55/21 papers, they are now of the view that 'Intelligent' PIR are acceptable.   

Estonian Maritime Administration

The Estonian Maritime Administration has outlined the minimum requirements of systems installed prior to 1st July 2011 in order to be recommended for exemption.

German Flag Authority

For a number of years Germany has required that all ships with a keel laying date after 1st January 1988 have to be equipped with a fixed installed 'Bridge Watch Alarm'.

Moreover, the national performance standard for that equipment is considered to be 'equivalent' but not identical with the standard adopted by the IMO.

Therefore, the German Administration referring to SOLAS Regulation v/19.2.2.4 has decided that all ships under German Flag with a construction date prior to 1st July 2011 and already equipped with a fixed installed 'Bridge Watch Alarm' in accordance with the German national requirements do not need to update their equipment to the new BNWAS in accordance with the new SOLAS requirements.

Greek Flag State

In principal the Greek Flag Administration requires the proposed BNWAS to comply with the IMO Resolution MSC.128 (75). This means that the relevant BNWAS has to be type approved in accordance with the IMO Resolution MSC.128 (75) and the International Standard IEC 62616.

Further to the above, the Greek Flag State doesn’t have any objection to accept a BNWAS to be equipped for reset functions with Infrared Motions sensors and also manual ‘push-button’ devices in order to be in compliance with the requirements of IMO MSC.128 (75) / para. 4.1.3.3. 

Marshall Islands - 

The Administration will accept BNWAS installed before 1 July 2011 that do not meet  MSC.128(75) provided:

  1.  The system is manufactured for marine service;
  2. Audible alarms or visual indicators are provided in the wheelhouse and on the bridge wings; and 
  3. Second and third stage audible alarms are raised in locations deemed appropriate by the Classification Society of the vessel.

 

A BNWAS installed after 1 July 2011 must be Type approved to meet the full requirements of MSC.128(75).

BNWAS, regardless of when installed, fitted with motion detectors to serve as the reset function must meet the following additional requirements:

  1. The sensors cover only the area of the bridge forward of any bridge curtains;
  2. The area of the bridge covered by the motion sensor does not include bridge chairs, unless the chair is integral to the primary conning position, such as in a cockpit style operating position; and
  3. Moving bridge curtains will not reset the BNWAS.

Maritime and Port Authority of Singapore (MPA)

MPA Singapore have issued a circular (No.21 of 2010) that directs those with Singapore vessels to the performance standards as set out in MSC.128(75).

MPA Singapore hold the view that PIR motion detectors are not acceptable as a method of resetting the BNWAS.
