Fire Safety Analysis of the Polar Icebreaker Replacement Design. Volume 3. Part 2
1987
Richards, Robert C.
This report documents the developmental application of the Ship Fire Safety Engineering Method(SFSEM) to the fire safety analysis of the Polar Icebreaker Replacement(PIR) design. The passive and active fire protection were analyzed in the integrated framework provided by SFSEM for every compartment on the PIR. Conventional fire protection engineering was employed whenever information necessary for SFSEM was not available. Recommendations for alternative solutions to fire safety discrepancies and guidelines for fire protection systems on the PIR are provided. Five levels of fire protection were found in the PIR design. Passive fire protection is the most significant factor in meeting fire safely objectives. The major improvement recommended for passive fire protection is to subdivide the boiler room. Refinements are recommended for active fire protection systems but the most significant recommendation is for improved and integrated automatic fire detection. With these changes fire safety of every compartment is well within the fire safety objectives established. Smoke control was identified as the area where the most significant gains could be made in fire protection and life safety. The Ship Fire Safety Engineering Method proved to be an effective method for integrating the five levels of fire protection on the PIR. An extensive data base was developed which will greatly facilitate future ship fire safety analyses. Output from SFSEM would be very useful in damage control planning. Volume 3 presents fire safety summaries for each compartment and its barriers. Keywords: Ship fires; Ship safety.
