What is the primary function of drenching systems fitted on roll-on/roll-off (Ro-Ro) vehicle decks?

✓

Direct Answer

Option A: Provide rapid total-area water coverage to extinguish vehicle fires quickly

Ro-Ro decks present high fire risks due to fuel loads and vehicle density. Drenching systems, as required by SOLAS, provide high-volume, rapid-response water coverage across the entire deck area. This immediate deluge is designed to suppress fires quickly before they can spread to adjacent vehicles or structural bulkheads.
