CO₂ System

Extinguishing fires in enclosed spaces requires solutions that can be deployed quickly and effectively with minimal risk to the environment and equipment.
The Survitec High Pressure CO₂ Fire Extinguishing System (Survitec CO₂ system) is a total flooding system for enclosed spaces. The system, proven to be fast and effective, has been supplied to hundreds of vessels worldwide.
The system can be applied on merchant marine and offshore structures, as the design is in accordance to SOLAS and IMO MODU Code. In addition, it is approved by all major classification societies.

KEY FEATURES

  • Options of manual or pressure operated cylinder top valves to quickly discharge the CO₂ gas
  • No requirement for electrical power, water or machinery to release the gas
  • The system is equipped with alarm devices which will pre-warn the crew to evacuate the protected space
  • A safe release delay function to ensure the safety of the crew
  • Sequential release design provides optimised protection to the enclosed space

BENEFITS

  • A cost effective solution for optimal system performance, keeping both installation and operational costs low
  • The system is available on rack modules to save installation time and cost
  • Quick discharge reduces potential cost of damages
  • Minimal and easy maintenance keeps operational costs low

TECHNICAL INFORMATION

SYSTEM DESCRIPTION AND CONFIGURATION

The cylinder bank and manifold are stored in a well-ventilated and insulated room. The pressure operated valves are connected to the manifold using flexible high-pressure hoses. From the main distribution valves, a piping system is used to distribute the gas to the discharge nozzles which are placed uniformly throughout the protected spaces. The top valves can be operated both pneumatically and manually. When releasing the system, the main distribution valve opens. The pilot

gas to the pressure operated cylinder top valve is delayed for a specified time. After the delay, the cylinder top valves open and the gas is discharged through the piping into the protected space. The valves can also easily be opened manually.  CO2 is highly suffocative, and the protected space must be evacuated before any CO2 is released. The Survitec CO2 system is designed with a pre-alarm system and a time delay function to allow the evacuation of the hazard area and avoid danger to the crew. The system can be complemented by the NFF XFlow LAFF system to provide total fire protection for the engine room. Local systems for paint lockers and galley ducting are available and smoke sampling systems for cargo holds can also be incorporated in the CO2 system package.

Extinguishing fire using CO2 

CO2 gas suffocates fire by reducing the oxygen content, thereby breaking the combustion chain. It is a colourless, non-corrosive gas that causes no chemical reaction to metals, electrical equipment or oil. The gas makes no mechanical damage to applied surfaces and leaves no residue to clean up. It is compressed to liquid state in high pressure cylinders for storage and it can be stored for an indefinite time.
