Fire Detection for Offshore Substations
Industry | Renewable Energy
Wind turbine fires can occur due to lightning strikes, which are more common due to the turbine’s height, as well as its exposed high-altitude location. Another significant percentage of fires are caused due to mechanical or electric malfunctions. As the turbine’s nacelle contains up to 200 gallons of flammable hydraulic fluid and lubricants, and the nacelle itself is made from flammable resin and glass fiber, the risk of ignition is high. This risk is increased by the presence of internal insulation that may be contaminated by oil deposits. Fire prevention solutions for offshore substations need to cater for these specific conditions. Learn more about how to mitigate these risks by implementing fire detection for offshore substations.
Electrical equipment, such as capacitors, transformers, generators, electrical controls and transmission equipment all have the potential to catch fire, as do Supervisory Control and Data Acquisition (SCADA) systems. Loose or broken electrical connections or overloaded electrical circuits are also a cause for concern.
Braking systems are also a high fire risk, as they may overheat. In this process, hot fragments of brake material may break off and become combined with expelled hydraulic fluid from ruptured hydraulic hoses. Hydraulic pumps and connections can also fail, allowing the fluid to ignite when it meets a hot surface.Â
Challenges
Due to the many fire risks present, a flame detection system is a critical component of every wind turbine configuration. Systems must be able to detect and suppress flames at the earliest stage, before a large fire erupts.
Fire Detection for Offshore Substations
Industry | Helipads
The main risk associated with helipads is the outbreak of fire and subsequent damage in case of an accident or incident occuring within its immediate vicinity. The key aim is to save lives in such an event.
The fire and rescue service requires survivable conditions, to rescue and provide escape routes for injured persons.
Challenges
Flame detection and suppression systems must detect flames rapidly to prevent a catastrophic fire.
