A Deck Integrated Fire Fighting System, or DIFFS, is a critical component of any helideck, as it helps to prevent and mitigate the risk of fires on offshore platforms and vessels. A DIFFS consists of a network of water and foam-based fire suppression systems that are integrated into the helideck structure itself.
Common key features of a DIFFS is as follow:
- Automatic fire detection and suppression: A DIFFS includes sensors and sprinkler systems that are strategically placed around the helideck, which can automatically detect and extinguish fires as they occur
- Manual firefighting capabilities: A DIFFS also includes hand-held hose reels and fire extinguishers that can be used by trained personnel to fight fires as needed.
- Water and foam-based fire suppression: A DIFFS typically uses a combination of water and foam to suppress fires. The foam helps to create a barrier between the fire and the fuel, which can help to prevent the fire from spreading.
- Integration into helideck structure: A DIFFS is typically integrated into the structure of the helideck, which allows it to be easily accessed and used by trained personnel in the event of a fire.
- Remote monitoring and control: A DIFFS may also include a remote monitoring and control system, which allows the system to be remotely activated and controlled from a central location. This can be especially useful in emergency situations where quick action is needed.
Typical of common components of a Deck Integrated Fire Fighting System, or DIFFS is as follow:
- Sensors: A DIFFS typically includes sensors that are strategically placed around the helideck to detect fires as they occur. These sensors can be activated by heat, smoke, or other indicators of a fire.
- Sprinkler systems: A DIFFS may include a network of sprinkler systems that are activated when a fire is detected. The sprinkler systems can release a combination of water and foam onto the fire to suppress it.
- Hand-held hose reels: A DIFFS typically includes hand-held hose reels that can be used by trained personnel to fight fires as needed. The hose reels can be connected to the DIFFS’s water supply and are typically equipped with nozzles that can release a steady stream of water onto the fire.
- Fire extinguishers: A DIFFS may also include fire extinguishers that can be used by trained personnel to fight fires as needed. The type of fire extinguisher used will depend on the type of fire being fought (e.g., Class A, Class B, Class C).
- Remote monitoring and control system: Some DIFFS systems may include a remote monitoring and control system, which allows the system to be activated and controlled from a central location. This can be especially useful in emergency situations where quick action is needed.
