Description
The present invention relates to a mobile water monitor, and more particularly, to a system and a method for designing the dimensions of each portion of a nozzle of a mobile water monitor so that a mobile water monitor can satisfy the radiometric and radial heights determined by IMO as performance requirements in international conventions .
Ship fires can be an obstacle to ship's ability to sink expensive ships and loaded cargoes and the lives and property of passengers and crew into the sea. It can be said that there is a great deal of artificial cases caused by natural ignition and carelessness of crew due to the characteristics of cargo. Ship fire has a slight difference depending on the cargo and the place where it occurs, but the fire spreads to the entire ship in an instant and stops the ship function.
Also, because of the characteristics that can not be easily supported from the land on the sea, which is isolated from the outside, ship fires cause huge loss of life and property. In particular, ships are made of steel with a high-speed structure, and fire suppression is a very difficult and dangerous task due to the walls and floors that are spread by the flames. Especially, when pier is pierced, it spreads to other vessels and the scale of fire can be developed into a large fire like land and building fire.
The SOLAS Convention on the Safety of Life, etc., stipulates the performance and arrangement of fire extinguishing equipment in order to ensure safety against fire in ships.
However, the conventional fire extinguishing apparatus is installed in the facilities inside the hull such as an engine room, a cabin, and a cargo hold of a ship, and a fire extinguishing system for protecting a container and the like installed in the open deck area of a container ship from fire is a fire hydrant and a fire extinguishing nozzle This is the only reality.

Container vessels that load more than five tiers of container in the open deck area (10) have been popularized recently due to the appearance of large container ships. Recently, 20,000 TEU container ships are planned to be loaded up to 11 tiers.
Mobile water monitors are required to be installed on vessels for the purpose of suppressing the fire by supplying digested water when fire occurs in the high-end (five or more stages) containers of such large container ships. IMO (4 sets) per container on vessels constructed on or after 1 January 2016 in accordance with the requirements of the International Convention for the Safety of Life at Sea.
However, the fire hydrants and fire extinguishing nozzles installed in the open deck area of existing container ships are intended to suppress the fire of the container loaded in the open deck area, but generally, fire extinguishing water can be supplied only to containers of 4 stages or less, It is difficult to apply to the open deck area of the recent large container ships where the container is loaded with more than 7 ~ 8 stages. Especially, it is difficult to meet the performance requirement newly redefined in the IMO international convention.
