Forget Data Analytics! Here comes Video Analytics for Minimizing Fire Risks

The What?

Yes! Here is an interesting piece of information where Video analytics are being employed to identify any visible source of oil mist or spray which could ignite and cause a fire.

Gimme Some Background:

Oil leakage hitting hot spots on engines is the most common cause of engine room fires on board ships.  According to DNV GL statistics, more than 60% of all engine room fires have been initiated by a hot spot and of these fires over 50% have been caused by oil leakage. Fires caused by oil leakage are often more serious than fires caused by other factors.

The fire detection and alarm system activation and crew actions are, by their nature, a reaction to the event.  The fire has to take hold and therefore have caused damage before remedial action takes place.  At the very least an engine room fire will cause severe disruption to the operation of the ship.

Oil leakage fires are most likely to be caused by oil mist, which can be formed through minute leaks in pressurized oil lines or when oil hits a hot surface and boils generating a mist.  Detection at this stage would create a pre-alarm warning and remedial action could be taken immediately to stop a fire occurring.

Tell me How It Works:

Fike Video Analytics analyses video from off-the-shelf video cameras to detect visible oil mist/spray in early stages and provides an alarm with live video to the engine control room, bridge, or anywhere on the ship.  To achieve the fast response required to minimize potential fire risks, the video analytics uses visual imaging, artificial intelligence and a neural network for fast processing of information.  The software learns the cameras’ field of view and monitors for characteristics of oil mist or spray known to cause flame or explosion.

The system incorporates detection algorithms for smoke (oil mist or spray), flame, reflected light and motion.  The algorithms can be used independently or in any combination.  Each algorithm can be configured with detection/blocking zones, sensitivities, time delays, etc., to target detection.  A small number of cameras can cover a wide area, or complex environments typical of engine rooms.

The video can be recorded for post-incident analysis and use video streamed from existing, off-the-shelf cameras.

Where Can I use it?

For shipboard applications, video analytics are commonly used in the following areas:

  • Diesel Generators and Diesel Propulsion Engines
  • Oil Fired Boilers
  • Incinerator Room
  • Purifiers and fuel modules
  • Emergency Diesel Generator
  • Auxiliary Emergency Diesel Generator
  • Mooring Deck

The use of video analytics is now a proven solution for engine room fire protection as well as other shipboard applications.  A camera network combined with video analytics creates a highly efficient means for rapidly detecting oil mist, a precursor to a potential fire or explosion.  The system can be monitored by shipboard personnel and linked to automation and safety management systems, allowing critical time to take action before disaster occurs.
