Fires occurring on offshore oil platforms and large oil storage tanks are classified among the most dangerous categories due to their level of complexity. During such incidents, the release of toxic gases and exposure to extreme temperatures significantly complicate intervention efforts. In many cases, firefighting vessels and other technical equipment are unable to approach the flame-engulfed platform even at a safe distance.

When developing the fire safety concept for such facilities, one of the most effective methods for open areas is the use of dispersed water — namely water mist or fine water spray technology. The system предусматривает the installation of pipeline networks equipped with numerous spray nozzles along the perimeter of the facility. Through high-capacity pumps, water is delivered under high pressure to this peripheral sprinkler network.

Once a fire detector is activated, the pressurized water triggers the sprinkler mechanism. The water stream is then atomized into fine droplets, forming a dense and homogeneous mist layer. This mist rapidly envelops the entire area and surrounds the fire source. Within a short period, a thick water cloud forms above the site, effectively isolating the flame from contact with air.

Oxygen is an essential element of the combustion process. As the flame draws in oxygen, it simultaneously encounters the water particles moving in the same direction. This interaction results in intense vaporization, and the generated steam layer restricts oxygen access to the fire seat. The continuous discharge of water mist and steam reduces oxygen concentration, suppressing combustion within a short time and creating conditions for complete extinguishment.

In industrial environments where other extinguishing agents are ineffective or difficult to apply, the water mist method has proven highly efficient. Moreover, the use of water as the primary agent makes this technology economically viable and widely applicable. On offshore platforms, the system can operate continuously by directly utilizing seawater, providing an additional logistical advantage.

In modern applications, dispersed water systems are equipped with intelligent, rotating nozzles. These nozzles adjust for wind direction and speed, ensuring targeted and precise mist distribution. Since strong winds can intensify flames and weaken the vapor layer, directional water flow is critically important. Smart nozzles guide the water spray toward the required direction, preventing wind from strengthening the fire and maximizing the effectiveness of the suppression process.
