Water sprinkler systems are designed to supply water to the sprinkler heads: to extinguish fires in rooms with explosive and flammable substances, and to cool water, cool decks, bulkheads, and shafts.

Schematic diagrams of sprinkler and water irrigation systems

The sprinkler system can be activated automatically or manually.
When the sprinkler insert of an automatic system is exposed to the heat of a fire, it decomposes. This opens the supply of fresh water from the pressure vessel (hydrophore) to a specific sprinkler, which begins to spray it on the heat source.
The sprinklers on the handheld system are constantly open and the system is not constantly filled with water. For the manual sprinkler system to operate, water must be added to the system or section of the system by manually opening the valve.
The sprinkler system consists of:

                           Centrifugal pump;
                           Connection to water fire protection system;
                           Connection to marine compressed air system;
                           Fresh water tank;
Hidrophoreore;
                           Pressure relay;

Other similar water-spraying fire-extinguishing systems

  • The water irrigation system for extinguishing fires in rooms with low air temperature, where flammable or explosive substances (crystals) are stored, as well as in place of insulation of Class A structures, i.e. cooling of exits from machine room shafts, room exterior surfaces.
  • The water barrier system is used to form continuous water barriers to stop the spread of flame and to cool the ship's hull structures.
  • The water spray system is analogous to the sprinkler system, except for the type of spray heads and the layout of the piping. This system is used for the protection of cargo pipelines and cargo tanks on open sections when carrying highly refrigerated gases (e.g. liquefied natural gas), as well as for the control of cargo handling stations and collectors.
  • Water curtain system is used to prevent the spread of fire through several vertical fire zones and to protect the watertight door from deformation during a fire.
    NOTE: Fine-sprayed water (in the form of mist) creates an oxygen-saturated environment in the room and extinguishes the fire.
