Locations within machinery spaces — such as above main and auxiliary engines, fuel oil purifiers, boilers, burners, and incinerator burners — are primary areas of concern and high fire-risk zones.
To mitigate this fire risk, Category A machinery spaces containing oil-fired boilers or oil fuel units shall be fitted with fixed fire extinguishing systems (SOLAS II-2/10.5.1.1). Additionally, Category A machinery spaces with a volume exceeding 500 m³ shall be provided with an approved fixed water-based or equivalent local application fire-fighting system [SOLAS II-2/10.5.6.1].
Such fixed water-based local application fire-fighting systems are designed to provide rapid protection for the crew and affected machinery without requiring engine shutdown, personnel evacuation, or sealing of the fire-affected space.
