When a ship sinks, the first priority of any rescuer is to actually locate the vessel in distress. It may seem easy, but in comparison to the size of an ocean, its not!
That's where an EPIRB comes in. An EPIRB is an Emergency Position Indicating Radio Beacon, and it is one of the most important pieces of safety equipment that is carried.
It transmits the location of the distress to satellites orbiting the earth, allowing rescuers to find you.
In this video, we take a look at how EPIRBs work, and see what you can do to make sure they work properly.

In June 2017, Queen Mary 2 rescued solo yachtsman Mervyn Wheatley from his disabled craft Tamarind in the Atlantic. Speaking to us later, he said Tamarind had taken on water after capsizing in the storm, and his EPIRB was triggered by falling into it (along with his previously dry socks!). He canceled that original distress call because Tamarind at first seemed salvageable, but upon realizing her steering gear was beyond repair he switched on the EPIRB manually. That call eventually brought QM2 alongside. If I recall, it was some 32 hours between his capsizing and rescue- quite the ordeal.

Great and informative video! I work for Washington State Emergency Management, (USA). We’re familiar with EPIRBs but any activations are handled by the US Coast Guard. We mostly get involved with similar devices-PLBs-Personal Locator Beacons and aircraft ELTs (Emergency Location Transmitters) during Search and Rescue (SAR) missions. Some devices have phone and text capability so you can communicate the nature of the emergency. A couple words of advice: First if you buy one of these devices enter your registration data as completely as possible. This improves the chances of being able to identify you, and contact you or a family member. Second, don’t “test” the device. As the video mentions, once the beacon is activated, it sends a signal to a Rescue Coordination Center, who will contact an agency like ours, and we in-turn will contact the county sheriff’s office. So you’ll end up getting at least three agencies spun-up over a false activation.

If you want to equip yourself with an EPIRB or PLB (personal locator beacon), make sure to pick a modern one with GPS. Standalone COSPAS-SARSAT will transmit your distress call, but is considerably inferior in getting a position fix both in accuracy and acquisition time. Due to the low number of COSPAS-SARSAT satellites, it can take up to an hour (if I remember correctly) to acquire a position fix. Also some of them are geostationary, which means accuracy is considerably lower in high latitudes. The worst thing you can have is an old beacon transmitting on 121.5 / 243 MHz - these are not received anymore at all. Another useful device for boating can be a SART, a Search and Rescue Transmitter, which will reply to radar signals and be directly visible on the radar screens of SAR units.

GNSS constellations of which GPS is one of several have been getting equipped with 406Mhz SAR receivers to receive the bacon's signals and eventually replacing some of the older SAR Sat's and its operational on some Galileo and some newer GPS Sat's now. Just to clear something up if the GNSS satellites around you aren't equipped with the 406 receivers but your beacon did have a GNSS receiver on it you would still be relying on the old LEOSAR and GEOSAR satellites to sent the GPS coordinates along with the usual coded signal to as GPS only transmits signals saying what the satellites position and the time the signal was sent towards the ground the GPS devices on the ground then uses several of the signals to figure out where it is they don't send any return signal for that so the GPS satellites require a separate receiver to be an actual part of the SARSAT network and that can only be added on the ground as a secondary payload before it's launched so only newer satellites are so equipped.

In case anyone wonders what happened to the Derbyshire that made it sink so quickly: The Derbyshire went through a Typhoon for 2 days with waves continuously crashing over the front of the ship, probably ripping off the covers of small ventilation pipes near the bow which resulted in the bow gradually filling with water over the course of the next two days. The bow dove deeper and deeper into the waves until eventually the crashing waves destroyed the hatch of the first cargo bay (which was filled with 157.000 tonnes of iron ore on that particular ride). The floods of water entered the cargo bays and quickly pulled the ship into the water. The waves started crashing further up the deck, eventually breaking through hatches 2, 3 4 and so on. That whole process cascaded down (or up) the vessel probably within seconds.

EPIRB sends signal to cospos sarsat whichever is in LOS. And then it gives the hexadecimal code to LUT. Then LUT gives position to MCC. MCC then sends the information to nearest MRCC. Then MRCC decided whether the SAR will go or the vessel in the vicinity of EPIRB will go.

I imagine that this can actually a benefit. Any unpowered survival craft (life rafts - which also automatically deploy when the ship is submerged rapidly, check out CN's video on them!) will be drifting with the currents as well, which will direct rescue efforts towards the survivors. Additionally, the units can be tethered to powered life-boats or life-rafts to keep them from going too far, if you had some time before your vessel went down.

Rich H I highly doubt the ocean somehow acts as part of the antenna system considering that water is a fantastic absorber of almost all radio waves except ELF, or extremely low frequency, which is not what GPS satellites use
@JNDlego57
@JNDlego57 3 жыл бұрын
Rich H Then please do explain how the ocean water acts as part of the antenna system. EPIRBs send their signals at 406MHz and 121.5MHz. When underwater, submarines use ELF, or extremely low frequency, which is only between 3 and 30 Hz. Not MHz, but Hz. ELF is able to travel roughly 120 feet deep into saltwater while barely having enough bandwidth to transmit a few words per minute. This is because any higher radio frequencies are able to travel mere inches in water. So unless you can somehow explain it, there is no way the ocean water can contribute to the transmitting/recieving ability of the EPIRB.

I have two questions: Why don't planes carry one of these? And for how long the batteries last? Do they need to be changed for every trip?

ELTs are the version of these for the aviation industry the FAA, transport Canada and EASA states requires them on board most aircraft Registered with them or flying within their airspace IIRC I'm not sure on other countries and no they don't need to be re charged don't think any of the different beacons have rechargeable batteries at all they do have expiry dates on the batteries that you to change them by and should change them after the beacon gets used.

How does the test setting work without actually sending out the signal to the satellite?
@peter_smyth
@peter_smyth 4 жыл бұрын
My guess is it has a little status light to show that it's on. Maybe they have a way of transmitting a test signal that gets relayed to the beacon's owners without triggering a rescue operation.
@tgm9991
@tgm9991 2 жыл бұрын
Pretty sure it sends a signal that the satellites are programmed to recognise and to just discard and don't relay and it will light up on the EPIRB to say it was transmitted. 406 beacons until just last year and only the very newest ones on the market never knew if any signal was ever received by anything so knowing it can sent a signal is all the test needs to check.

If using an EPIRB is a distress signal how can the vessels in vicinity detect that you have activated it?
@vollelektrolysierer5773
@vollelektrolysierer5773 3 жыл бұрын
First of all, the MRCC handling the rescue can put out an area or general call to all ships in the vicinity of the EPRIB using radio or satellite communication, letting them know of the distress. In addition to the 406 MHz satelitte signal, most EPIRBs send a weaker signal on 121.5 MHz for vessels and aircraft to home in on. Some come with an intergrated radar transponder (SART), that will show a distinctive signal on the screen of nearby vessels when hit by their radar beam.

Some, like the one I have on my boat, also transmit an AIS signal, which will be picked up by any vessel with an AIS receiver.

The ship wouldnt need to flood each and every compartment simultaneously in order to sink. If one were to capsize with a breached hull, it could sink in seconds and it would slowly fill with water as it goes down.

Roll on roll off ferries have a lovely huge open vehicle deck that can be easily filled in seconds and such ferries have done down real quick in the past. Vessels have literally split in two in rough seas as well well in the past that'll do it real quick too. Physics can be a a cunt like that sometimes

They transit a signal on 121.5Mhz the international aviation emergency frequency which can be used to locate the beacon by aircraft with the required equipment other aircraft will hear a siren sound every few seconds or so on 121.5mhz if they are monitoring it.
