| Engine/Turbine Systems |
On vessels, drilling rigs, platforms and industrial
plants, suppression systems are installed to extinguish fires which may
occur, usually Class B combustibles. These systems are usually required
by the local regulatory body. The type of agent and amount may vary between
regulatory bodies. Presently the European community is requiring the removal
of all Halon 1301 systems in offshore applications by 2003.
Different design standards are used depending on the extinguisher medium.
The NFPA standards are typically used, however in the offshore market there
is also SOLAS to consider and in Europe most countries use the EN standards.
Depending on the requirements, there can be a significant cost impact from
one standard to the next.
Some of the agents Advantage has experience with for suppressing fires
in engine rooms and turbine generators are listed below: |
| Halon 1301 (both low and high pressure systems) |
Inergen (150 bar, 200 bar, and 300 bar) |
| Carbon dioxide (both low and high pressure systems) |
Argon systems |
| FM-200 (both low and high pressure systems) |
Water mist (low, medium, and high pressure systems)
|
| FE-13 Systems |
Foam (both medium and high expansion) |
|
| When designing these systems, the following
information is needed: |
| Preferred extinguishing medium (carbon dioxide,
FM-200, FE-13, Inergen, Argon, water mist or foam) |
Location (flag state, body of water, country,
state, or county)
Regulatory agent (classification society, governmental body,
local fire authority, insurance agency) |
| Dimensions of the space (length, width, and height) |
| Application (vessel, drilling rig, platform,
or industrial plant) |
|
| |
| Engine Shutdown Systems |
Engine shutdown systems are used in the Gulf of Mexico to conform with
Code of Federal Regulation requirements.
|
| Fire Water Sprinkler Systems |
Industrial fire water sprinkler systems are typically deluge systems
used for exposure protection.
|
|
| Galley/Kitchen Hood Systems |
Galley/kitchen hood fire suppression systems are required for nearly
all commercial cooking hoods and for galley hoods on offshore installations.
The term galley hood is typically associated with marine
facilities while kitchen hood is typically associated with
commercial facilities.
In the United States commercial kitchens require protection of the hood,
the plenum area behind the filters, the duct, and the appliances under
the hood in accordance with NFPA 17A. The accepted standard by all USA
manufactures is the Underwriter Laboratories test standard commonly
referred to as UL 300. The shift to the new UL 300 test standard came
about as a result changing to a more energy efficient appliances and
a shift from using animal fats to vegetable fats to cook with.

| Vent Snuffing Systems |
Vent snuffing systems are usually installed in applications where vents
or flares are used to dispose of waste products in the oil production
process. Typically found on offshore platforms, these systems are often
employed as a safety measure to either extinguish a flame or to purge
the lines associated with the flare and vent lines, out of service.
Unlike the design guidelines for other systems, which are found in the
NFPA Standards, guidelines for these systems are found in the US bureau
of Mines or the American Gas Association. The quantity of extinguishing
or inerting agent is usually based on a reduced flow of the vent for
a given gas, usually 10% of the maximum flow rate. Nozzles are located
10 feet from the end of the flare and sized to provide a specific extinguishing
agent flow rate.
When designing vent snuffing systems, we need only the following
information:
| Preferred extinguishing medium (carbon dioxide,
nitrogen, dry chemical, or water) |
Maximum vent flow rate |
| Elevation at the end of the flare end above extinguishing
system |
Distance between flare end and extinguishing
system |
|
Systems can be configured for either automatic or manual release. They
have been designed with a reserve system and control valves to permit
purging any one of several flares where multiple flares are present.
Our designs include cylinder racks suitable for open deck installations
and single point lifting. Where cylinders are exposed to the environment,
an overhead shield can be provided.
