ALERT2 Man-Overboard Alarm System™ versus AIS

There is a lot of hype about an AIS (Automatic Identification System) device as being the solution of a Man-Overboard Alarm device. The truth is, an AIS device is not necessarily the best solution for a Man-Overboard (MOB) situation because of the lag-time associated with its technology. The ALERT2 Man-Overboard System is all about knowing a MOB has occurred in seconds, the greatest chance of rescue is from the vessel the MOB fell from. Here are the differences:

At this point the ALERT2 is already transmitting to ALERT2 Receiver.Luckily MOB is alert and now above the waves. MOB looking at surroundings trying to get barrings. Hopefully not panicked, MOB needs to remember how to activate AIS.
What is happening on vessel? (+20 sec.)ALERT2 Receiver howls and crew take action to search for MOB. If the boat has ALERT2 Receiver wired for engine kill, the boat has stopped moving.If MOB is successful, AIS is turned on. If first attempt fails, other manual activation may be required. Once activated AIS searches for GPS coordinates.
Search & Rescue (+30 sec.)Crew on vessel are looking for a visual of MOB. Once sighted, a crew member will lock-on to MOB as others begin rescue.Once GPS coordinates are located, the transmission to AIS-enabled receiver receives broadcast. Furthermore, the AIS icon may appear on the chart plotter as a vessel, not a MOB – so crew may still not be aware of person overboard.
1 minute has passedVessel traveling 6 knots has separated 600 feet from MOB! ALERT2 MOB has either been sighted or ALERT2 Portable Direction Finder is able to home in on signal.Because of lag-time, MOB will probably no longer be in sight. All rescue will be dependent on following GPS coordinates.
3 minutes have passedWith transmission of alarm automatic, evasive action has commenced and rescue is well on way.In reality rescue is probably just beginning.

When Mere Seconds Count

There are a dozen products on the market that are identified as fall-overboard locator beacons. Our product, the ALERT2 Man-Overboard Alarm System™ has two functions that differentiate from the other fall-overboard locator beacons on the market.

For a vessel moving 6 knots, a person who has fallen overboard will drift 100 feet in 10 seconds, 600 feet in 60 seconds. In between that 10 and 60 seconds, even on a clear day, they are no longer visible to the crew on the boat they just fell off of. When time is of the essence, ALERT2 is far superior to the other fall-overboard locator beacons.

Coast Guard Releases Towing Industry Safety Data from 1994 – 2014

In 2014 there were four crew fatalities, which is the lowest number on record. Three of the four were a result of crew-members falling into the water. In the past 20 years, 72 fatalities have been a result of falling into water. Emerald Marine Products is glad to see that the number has been reduced over the years, thanks to better prevention and heightened awareness. On average, three fatalities a year occur due to falling in water. In the past eight years, an average of 15 fall into water accidents occur each year, of which six tend to be serious (if not fatal) occurrences.

Though AIS Is Required, It May Not Be the Best Solution for Your Safety

The ruling, “Vessel Requirements for Notices of Arrival and Departure and Automatic Identification System”  becomes effective March 2. However, you have until March 1, 2016 to install the AIS.

AIS or Automatic Identification System is now required on all vessels 65 feet or longer. Primarily for the benefit of being able to identify boats in the area, AIS has also been touted as a life-saving technology with fall-overboard (FOB) awareness and location of person who fell overboard using GPS technology embedded in the AIS device. However, the truth is that AIS is not the best solution for FOB awareness or for that matter, the location of the person who fell overboard.

Why Is a Water Rescue Training Dummy Named Oscar?

For over one-hundred and fifty years, vessels worldwide have used flags to communicate important messages regarding safety and other related matters to passing ships. The “O” flag is part of the International Code of Signals used for Man-Overboard (MOB) occurrences. Vessels may communicate a MOB situation using the phonetic pronunciation of “O” by calling out “Oscar” so the receiver clearly understands the speaker is communicating “O”. Since Oscar has become synonymous with MOB, it only made sense for our water rescue training dummy to be called “Oscar”. However, you can call our product anything you like, as long as you respect the powerful tool that it is. For further information about OSCAR Water Rescue Training Dummy or other maritime life-saving products contact Emerald Marine Products.
