An arrangement in a fire water system, especially for an offshore platform, wherein the system comprises one or more fire water pumps (6) connected through a pipe system (2-5) to a number of deluge valves (812) coupled to associate with pipe stretches leading to respective fire sections. The arrangement comprises a distribution manifold (2) having an upstream side (3) which is in open connection with the fire water pumps (6) and with a buffer tank (7) for water, and having a downstream side (4) connected to the deluge valves (12) which are coupled to said pipe stretches, and there is also provided a gas supply means (10) connected to the buffer tank (7) and having a pressure which is sufficient to see to it that the water pressure at the upstream side of the distribution manifold does not sink below a predetermined level after activation of the deluge valves (12). The distribution manifold (2) and the deluge valves (12), preferably also the buffer tank (7) and the gas supply means (10), are arranged as an integrated unit within a delimited area which may advantageously be constituted by a container (1).
