DELUGE SUCCOUR is an efficient medical rescue system specifically designed to address urban flood disasters. It includes three primary components: a waterborne medical rescue vessel, a small water rescue transfer boat, and a near-shore material transfer station. This system features a modular structure that can be adapted to various rescue scenarios by separating and combining as needed. It effectively supports the four critical phases of flood disaster response: water rescue, emergency medical treatment, personnel transfer, and supply replenishment.
