Annex 1 Recommendation on performance standards for sound reception systems


1.1 Sound reception systems are acoustical electronic navigational aids to enable the officer on the watch to hear outside sound signals inside a totally enclosed bridge in order to perform the look-out function as required in the International Regulations for Preventing Collisions at Sea, 1972.

1.2 Sound reception systems should, in addition to the general requirements contained in resolution A.694(17), comply with the following minimum requirements.


2.1 Sound reception systems should be capable of:

.1 receiving sound signals from all directions in the audio band 70 Hz - 820 Hz;

.2 reproducing incoming sound signals acoustically inside the bridge;

.3 indicating the approximate direction of incoming sound signals to determine at least whether the sound signal being detected is forward or abaft of the beam and from which side of the ship it is being detected; and *

.4 suppressing unwanted background noise and allowing reception of meaningful sounds.


3.1 Incoming sound signals should be reproduced inside the bridge by means of at least one loudspeaker.

3.2 The volume should be adjusted by means of one volume control only. The volume control should be capable of being set so that the sound pressure level of an incoming signal only is at least 10 dB(A) above the bridge noise level.

3.3 There should be a display which gives a visual indication for at least 3 s of the incoming signals and their approximate direction.


4.1 The microphones should be installed in such a way that they are as far from noise sources in the ship as is reasonably practicable and wind induced noise and mechanical vibrations are reasonably reduced.

4.2 The display should be installed so that it is visible at least from the conning position.

4.3 The loudspeaker(s) should be installed so that incoming sound signals are audible at all positions inside the bridge.

*This may be accomplished by means of at least four microphones and separate reception channels.

Annex 3 Recommendation on performance standards for an integrated navigation system (INS)

1 Scope

1.1 The purpose of an integrated navigation system (INS) is to provide 'added value' to the functions and information needed by the officer in charge of the navigational watch (OOW) to plan, monitor or control the progress of the ship.

1.2 The INS supports mode and situation awareness.

1.3 The INS supports safety of navigation by evaluating inputs from several independent and different sensors, combining them to provide information giving timely warnings of potential dangers and degradation of integrity of this information. Integrity monitoring is an intrinsic function of the INS.

1.4 The INS aims to ensure that, by taking human factors into consideration, the workload is kept within the capacity of the OOW in order to enhance safe and expeditious navigation and to complement the mariner's capabilities, while at the same time to compensate for their limitations.

1.5 The function of passage execution in an Integrated Bridge System (lBS), as defined by the Organization , may be performed by an INS.

*Resolution MSC.64(67), Annex 1- Recommendation on performance standards for Integrated Bridge Systems

2 Application

2.1 These performance standards are applicable to any combination of navigational aids that provides functions beyond the general intent defined in the respective performance standards adopted by the Organization for individual equipment.

2.2 The purpose of these performance standards is to support the proper and safe integration of navigational equipment and information.

2.3 These performance standards define three categories of INS:

.1 INS(A) for systems that provide the minimum functional requirements of the INS including a consistent common reference system;

.2 INS(B) for systems that, in addition to the functional requirements of INS(A), provide the information needed for decision support in avoiding hazards; and

.3 INS(C) for systems that, in addition to the functional requirements of INS(B), provide the automatic control functions of heading, track or speed.

3 Definitions

For the purpose of these standards the following definitions apply.

3.1 Automatic control system - A control system that may include a heading, track or speed control system.

3.2 Consistent common reference system - A sub-system of an INS for acquisition, processing, storage and distribution of data and information providing identical and obligatory reference to sub-systems within an INS.

3.3 Integrated navigation system - An INS is a combination of systems that are interconnected to increase safe and efficient navigation by suitably qualified personnel.

3.4 Integrity - Ability of the system to provide the user with information within the specified accuracy in a timely, complete and unambiguous manner, and alarms and indications within a specified time when the system should be used with caution or not at all.

3.5 Multifunction display - A single visual display unit that can present, either simultaneously or through a series of selectable pages, information from more than one operation of a system.

3.6 Sensor - A navigational aid, with or without its own display and control as appropriate, automatically providing information to the INS.
