3、quirements intended to prevent the onset of a fire. However, even with all the preventative measures taken, shipboard fires still occur. Therefore, the proper design, installation and operation of the vessels fire-fighting systems are critical to the safety of a vessel and the personnel onboard. Sin

4、ce fire-fighting systems are so critical, the designs and arrangements of such systems should be carefully evaluated for compliance with the ABS requirements by the designer and ABS Engineering staffs. These Guidance Notes have been developed to assist in a better understanding of the ABS requiremen

5、ts for such systems. They are intended to provide a general overview of ABS requirements that should be considered during technical plan review activities. These Guidance Notes also examine the basic scientific fundamentals of fire, as appropriate for a proper understanding and application of the AB

6、S requirements. Accordingly, this document should be considered as general guidance only and the technical reviews of fire-fighting systems should verify compliance with all ABS Rules applicable to the specific vessel involved. Note: Rule references in these Guidance Notes (e.g. 4-7-2/1.1.1, etc.) a

7、re typically to the requirements found in the ABS Rules for Building and Classing Steel Vessels, unless noted otherwise. Scope The scope of this document is limited to the review of ABS requirements considered during the technical plan review of active fire-fighting systems onboard ABS-classed vesse

8、ls. Passive fire protection arrangements, such as structural fire protection, as well as fire detection systems, are outside the scope of this document. Fire-fighting systems of offshore facilities and installations are also outside the scope of this document. The review of fire-fighting systems for

9、 the International Maritime Organizations (IMOs) International Convention for the Safety of Life at Sea (SOLAS) requirements is also not within the scope of this document. However, in many cases, the ABS Rules for fire-fighting systems either incorporate or directly reference IMO SOLAS fire-fighting

10、 system requirements. Accordingly, within the discussions of the ABS requirements for various fire-fighting systems, related “interpretations” of the associated SOLAS requirements, as developed by the International Association of Classification Societies (IACS), are identified. These IACS interpreta

11、tions are called Unified Interpretations (UI). As an IACS member, ABS is obligated to apply these UIs as appropriate interpretations of the SOLAS requirements, unless directed otherwise by the Flag Administration. Interpretations provided in the UIs should be considered when conducting technical pla

12、n reviews. Note: Development of appropriate Unified Interpretations and revision of existing UIs is an ongoing effort within the IACS Working Parties. Therefore, attention is directed to the latest edition of the IACS UI being available on the website http:/www.iacs.org.uk/index1.htm. In addition to

13、 the IACS UIs, IMO MSC Circular 847, “Interpretations of Vague Expressions and other Vague Wording in SOLAS Consolidated Edition 1997 Chapter II-2,” also provides guidance regarding SOLAS fire-fighting system requirements. Many of the MSC Circular 847 interpretations are based upon the IACS UI inter

14、pretations, while others provide revised or additional interpretations of the SOLAS requirements. A number of the MSC Circular 847 interpretations have been included in the SOLAS 2000 consolidated edition. Consequently, these requirements were also incorporated into the ABS Rules. However, since the

15、 MSC Circular 847 interpretations identify useful information and guidance relative to certain Rule requirements, “selected” IMO MSC Circular 847 interpretations have also been identified. Note: Regarding classification requirements, MSC Circular 847 interpretations which are not included within SOL

16、AS have not necessarily been officially adopted by ABS and should only be applied as directed by the ABS Technical Consistency Department. Further, MSC Circular 847 interpretations may not be mandatory for any particular Flag Administration, except for those incorporated within SOLAS. Member Governm

17、ents are only invited to use the annexed interpretations as guidance, and therefore, specific instructions from the ABS Regulatory Affairs Department should be obtained regarding the application of these interpretations on behalf of any particular Administration. iv ABSGUIDANCE NOTES ON FIRE-FIGHTIN
