Fire Protection for the Marine Industry

At sea, safety requirements for ships are of the utmost importance. This also applies to fire protection measures. After all, in the event of fire, rapid escape is usually impossible and the prompt arrival of help from outside cannot be expected.

In light of the various types of fire risks which exist on board ships, specific solutions are necessary for the space or object to be protected in order to ensure optimal fire protection on board.

Areas that deserve special attention include machine rooms and rooms with electrical and electronic devices, such as control rooms and switch cabinets. In the event of a fire, the failure of machines or devices on board a ship at sea can have fatal consequences. In such risk areas, fire suppression systems must put out fires quickly and residue-free, in order to ensure that sensitive equipment is not damaged.

If you’re building a new vessel or retrofitting an existing one, the best fire protection decision you can make is to select a Gielle Marine Fire Suppression System with Novec 1230 fluid. 

GL Novec 1230 Marine Fire Suppression System designed for use with 3M Novec 1230 fire protection fluid is engineered to provide clean, fast, people-safe protection for applications requiring a “green” solution to fire suppression. The system includes detectors, a control unit, agent storage cylinders, piping and discharge nozzles. The system is computer calculated to provide system discharge within 10 seconds. 

Here’s why:
Life Safety. Novec 1230 fluid, like halon 1301 and other halon replacements, works by interrupting the fire on a molecular level, not by taking oxygen from the protected space. It is one of the preferred fire suppression agents for protection of shipboard spaces where crew or other occupants may be present. 

Environmental. Novec 1230 fluid has an ozone depletion of potential of zero and the lowest global warming potential of any clean agent available making Novec 1230 fluid the natural choice for customers concerned about the environment.

Marine Approvals. Gielle Marine Fire Suppression Systems with Novec 1230 fluid are approved for use in marine applications such as machinery spaces and flammable liquid storage areas by major regulatory agencies.

Weight and Space. Gielle Marine Engineered Systems weigh less and take up less space than either carbon dioxide or water mist systems, so they provide more fuel-efficient solutions to shipboard fire protection with more room for revenue-generating cargo or passengers.

General description
GL Novec 1230 Marine Systems with Novec 1230 fluid are used to suppress fires in specific hazards or equipment where an electrically non-conductive agent is required, where agent cleanup creates a problem, where extinguishing capability with a low weight is desired and where the hazard is normally occupied.

GL Novec 1230 Marine Systems with Novec 1230 fluid are intended to protect spaces containing the following hazards:
• Class A: Surface type fires; wood or other cellulose-type material
• Class B: Flammable liquids
• Class C: Energized electrical equipment

3M Novec 1230 fire protection fluid
Novec 1230 fluid is a fluoroketone developed specifically by 3M for fire protection use. It is a compound of carbon, fluorine and oxygen (CF3CF2C(O)CF(CF3)2). It is colorless, low-odor and electrically non-conductive. It suppresses fire by a combination of chemical and physical mechanisms without affecting the available oxygen. 

This allows personnel to see and breathe, permitting them to leave the fire area safely.  Novec 1230 fluid is approved for use in occupied spaces by the U.S. EPA. Marine regulations require that personnel are evacuated before system discharge.

Novec 1230 system hardware
Novec 1230 fluid is stored in steel cylinders superpressurized with nitrogen to 25-bar (360 psig).  The cylinder valve assembly is equipped with a supervisory pressure switch connection for monitoring cylinder pressure.

A pressure gauge and a safety disc are fitted to the valve in accordance with DOT requirements. Other system components include mounting brackets, control heads, pull stations, pilot cylinders, flex hoses, discharge delays, sirens, check valves, nozzles, etc. System controls can be configured to comply with all marine regulatory requirements.

One of the advantages offered by NovecTM 1230’s high boiling point is that it produces a very low vapour pressure, enabling it to be transported in lightweight totes or drums as opposed to steel pressurised containers. This allows NovecTM 1230 to be readily air freighted and as both initial filling and recharging operations are possible by simply pouring the fluid into containers, prior to superpressurising, the filling operation is far simpler than with traditional high pressure gases.

The system piping design is accomplished with Gielle flow calculation software, which performs the complex flow calculations necessary to achieve agent distribution with a discharge time of ten seconds or less.


There's a distinct advantage in handling a liquid agent-one that isn't pressurized and doesn't have a high vapor pressure at room temperature. 3M Novec 1230 fire protection fluid has a boiling point of 49°C (121° F). It can be shipped safely and effectively, without any restrictions, by air at a moment's notice in bulk quantities. In the shop, Novec 1230 fluid is easier to use than pressurized gas. Simply transfer the fluid from the container to the system cylinder, using a simplified closed loop process to avoid contamination. Then, superpressurize the cylinder with nitrogen.

The product is ideal for use in total flooding applications, localized flooding systems, directional spray type applications and may be used in portable extinguishers for specialized applications. But in addition to the conventional methods of super-pressurization using nitrogen, 3M Novec 1230 fire protection fluid also lends itself for use in pump applications because it is a liquid.

Replacing halon with novec 1230 fluid
3M Novec 1230 fire protection fluid is a next-generation halon alternative designed to balance industry concerns for performance, human safety and the environment, which makes Novec 1230 fluid the first option to non-sustainable technologies:

•Zero ozone depletion potential
•5-day atmospheric lifetime
•A global warming potential of 1

Its low acute toxicity, combined with high extinguishing efficiency, give 3M Novec 1230 fire protection fluid a significant margin of safety, even at relatively high extinguishing concentrations. This makes Novec 1230 fluid ideal for occupied spaces including engine and pump rooms, paint lockers and communication and control centers

3M Novec 1230 fire protection fluid offers a number of important advantages over other clean agents and CO2 in marine applications.

Its low acute toxicity, combined with high extinguishing efficiency, give Novec 1230 fluid a significant margin of safety, even at relatively high extinguishing concentrations, making Novec 1230 fluid ideal for occupied spaces including

This environmental profile is unmatched by any other halogenated agent, and helps make 3M Novec 1230 fire protection fluid today's long-term solution for protecting your high value assets.

The Gielle Marine System is the most optioned system as a Halon replacement system. Often, the system can be dropped into existing pipework reducing retrofit time and costs.

Despite having a high boiling point, NovecTM 1230 is able to be effectively vapourised over a wide range of hazard temperatures.

It is therefore available to protect most hazards traditionally protected with Halon 1301 and will be particularly important in Marine applications and others where high margins of safety and long term sustainability are considered to be crucial features.

The physical properties of each halon alternative determines how much agent is required to provide an equivalent level of protection. NovecTM 1230 will require approximately twice as much agent by weight as the equivalent halon system, although end use design concentrations will be similar, resulting in minimal increases in storage space for the containers.

Existing pipework may need to be replaced or supplemented, although the exact requirement for any particular system can only be determined after a detailed review of the existing installation.
