In the event of a spontaneous outbreak of fire in a ship, it is necessary to secure sufficient time for the safe evacuation of the personnel on board and for the crew to engage in fire extinguishing activities. Fire spread prevention designs are to be developed to sufficiently take care of the requirements of an ever increasing number of light weight vessels, such as high speed crafts made by aluminum alloys, which are highly prone to develop ruptures when exposed to the high temperature of a marine cell fire. The performance assessment of such designs should be settled down immediately, with special emphasis on the faultless design of fire preventive partitions, bulkheads and ceilings. This paper makes an investigation of the threshold conditions and characteristics of the problem of the spread phenomena of cell fires enhanced by ruptures and holes broke open on the partitions and structural members on light weight vessels by using a mathematical model which gives the combustion characteristics. The relationships between the critical fire spread conditions and the governing factors which are, the point of rupture of structural member, the thickness of the fire preventive insulation and the fire load, are clarifired through the results of the numerical calculations.
