Fire main


A sea water supply system for fire hydrants. It consists of sea inlets, suction piping, fire pumps and a distributed piping system supplying fire hydrants, hoses and nozzles located throughout the vessel. Each vessel is to be provided with at least two main fire pumps. If the arrangements for the two main fire pumps are such that a fire in one space can put both main fire pumps out of service, an emergency fire pump is required to be provided.
