Deluge systems

Deluge is an open nozzle system, meaning ALL nozzles in the protected area are released simultaneously. When the deluge system is triggered, a massive amount of water is released very quickly, making it an extremely effective way to extinguish fire. When coupled with the SemSafe system, your facility's critical interior and exterior spaces are safeguarded against fire damage.

The four broad types of deluge protection include:

  • Area protection
  • Equipment protection
  • Structural protection
  • Water curtain
Deluge systems-1

All our deluge skids are designed according to the latest regulations and customer requirements and with strict focus on working environment and accessibility during operation and maintenance. 

We can design the complete deluge system including nozzle arrangement and hydraulic calculations.

SemSafe

Water Mist System

Advantages of our SemSafe Water Mist System:

  • Ready for re-use immediately after a fire - no expensive refilling costs after use.

  • Considerably less costly than some systems using gas.

  • As effective as gas systems with no negative impact on the environment.

  • Very low water consumption unlike low or medium pressure systems.

  • Fine water mist causes little or no damage to even electrical equipment.

  • The mist cools area and so prevents re-ignition.

  • Downtime is kept to a minimum following a fire.

  • The pump unit takes up little space and needs no special room or safe storage.

  • Easy and fast installation is possible, due to small pipe size and low system weight.

Safe and reliable

Helideck firefighting systems

We can provide a full range of helideck firefighting:

  • Foam concentrates
  • Foam monitor
  • Dual agent fire extinguishing 
  • Deck integrated firefighting (DIFF)

Nitrogen generation system - N2

Nitrogen is an indispensable component in a number of processes. Most commonly, nitrogen is used to create an inert environment for preventing explosions and for fire safety and to support transportation and transfer of hydrocarbons. Additionally, nitrogen is used for pipeline testing and purging, cleaning technological vessels and cleaning liquefied gas carriers and hydrocarbon storage facilities.

Common markets are:

  • Offshore
  • FPSO (Floating, Production, Storage and Offloading unit)
  • Drill ships and rigs
  • Power solutions marine
  • Chemical tankers
  • LNG/LPG - Liquified Natural Gas carriers/Liquified Petroleum Gas carriers
  • PSV (Platform Supply Vessels)
Fixed Gaseous System

Inert gasses are used to extinguish fires in flammable liquids and also in electrical equipment

  • All inert gasses are found naturally in the atmosphere.
  • They are harmless to personnel at the design concentration
  • There are no toxicological factors associated with the use.
  • Inert gasses can be used to extinguish fires in almost all flammable materials.
  • Suitable for extinguishing fires in flammable liquids and is not electrically conducting and therefore excellent for extinguishing fires in electrical equipment.
  • Extinguishing with inert gas means reducing the oxygen content within a room to the point at which fire can no longer burn (typically to 12-13 % oxygen)
  • No compromising of the safety of individuals present (amount of oxygen in the air we breathe is approx. 21%).
Dual agent fire extinguishing system

SemDual: Protecting helicopter landing areas according to Norsok standard S-001

  • Foam is the only proven fire fighting system against fire on heli-decks. Our systems are certified according to international standards.
  • SemDual is a manually operated unit, discharging dry chemical powder and AFFF foam.
  • It is built for the protection of a helicopter landing area according to Norsok standard S-001.
  • In operation, the dry chemical gives a quick knock down of the fire, and the water/AFFF foam mix gives cooling and a sealing surface to prevent re-ignition.
  • SemDual is connected to the firewater ring main system via a standard flange connection.
  • Correct mixing of foam is achieved through an in-line inductor.
