MOB Guardian

MOB Guardian was developed as a twenty-first century aid to sea safety, designed to help save the lives of fishermen at sea. MOB Guardian provides safety cover for both the fishing vessel and individual crew members. When at sea, MOB Guardian connects with the RNLI Operations Room. The fishing boat sends automatic updates of its position at hourly intervals, if contact is lost the shore-side system automatically tries to re-establish contact. If contact cannot be established with the MOB Guardian unit, the RNLI operations room is alerted and they confirm if the boat is at sea. If so details are passed to the Coastguard, who accept it as a Search and Rescue (SAR) alert.

MOB Guardian was designed to help save the lives of fishermen at sea.
In addition, each crew member wears a personal safety device (PSD), which communicates constantly with the base unit. If a crew member falls overboard the communication link is broken and the base unit sounds a very loud klaxon aboard the fishing vessel. The base unit displays the range and bearing back to the GPS position of the man overboard incident and automatic alerting to the RNLI via the Iridium satellite system in less than three minutes.

 

The benefit of fitting MOB Guardian is that the RNLI can pass the last known position, course and speed of the fishing boat to the Coastguard who will initiate a SAR mission.

How it Works

As soon as the fishing vessel goes to sea, MOB Guardian uses the Iridium SBD service to connect with the RNLI operations room. The RNLI system then expects the MOB Guardian unit to automatically update its position at hourly intervals. If contact is lost, the shore-side system automatically tries to re-establish contact. If contact cannot be established with the MOB Guardian unit, the RNLI operations room is alerted to confirm if the boat is at sea, if so details are passed to the Coastguard.

The Personal Safety Device (PSD), worn while working on deck, is constantly in radio contact with the base unit. If a crew member falls overboard, it breaks the PSD’s radio link and triggers an on-board alarm and the RNLI operations room is automatically alerted of the life-threatening event. Details are passed on to the Coastguard, who accept it as a Search and Rescue (SAR) alert.


Tech Specs & Features

MOB Guardian provides safety cover for both the fishing vessel and its individual crew members. As soon as it goes to sea, MOB Guardian connects with the RNLI Operations Room.

Vessel visibility
1. The MOB unit sets a safety 'geo fence' around the vessel while it is moored in port or visiting a port.
2. When the vessel passes through the 'geo fence' the MOB unit starts sending hourly reports with its position to the RNLI operations centre.
3. The MOB Guardian system looks for the vessel every hour and waits for the vessel's 'we're safe' report.
4. If the vessel fails to send its 'we're safe' report the system sends an alert and the RNLI operations centre investigates.
5. If contact cannot then be made with the vessel the 'alert' is passed to the Coastguard for action.

Individual crew
1. As soon as the MOB Guardian unit is powered up, the personal safety devices (PSDs) are operative.
2. Each crew member takes a PSD from the unit and either wears it around their neck or places it in their pocket.
3. If a crew member falls overboard, submersion of the PSD will cause it to lose contact with the unit.
4. The MOB Guardian unit sounds an alarm almost immediately onboard, to alert other crew members.
5. After 2 minutes, the alert is automatically transmitted to the RNLI Operations Room, with a GPS position of the man overboard incident. The coastguard coordinates a rescue.
