Every crew member, accounted for.
Marriner Marine Technologies is developing MMT Sentinel, a man-overboard detection and crew-location system built for the realities of working vessels.
Overboard happens fast, and often unseen.
On a working deck, someone can go into the water during hauling, at night, in heavy weather, or with a short crew, and no one may notice for minutes.
Those minutes decide the outcome. We're building tools that give crews another way to know where everyone is, and to know sooner when someone isn't where they should be.
MMT Sentinel
Man-overboard detection and crew-location system
Crew awareness
Real-time status for each crew member wearing a device, shown clearly to the operator.
Faster alerts
Designed to flag a potential man-overboard event quickly, with audible and visual alerts on board.
Built for the deck
Developed with commercial fishing crews in mind and tested aboard a working vessel.
Development progress
Read development updates-
Prototype bench testing
First prototype hardware brought online and tested on the bench.
-
First vessel field test
Tested aboard a working commercial fishing vessel in real conditions.
-
Controlled validation
A formal validation session, followed by an independently validated performance improvement.
-
Vessel-scale development
Preparing for expanded trials aboard larger and more varied vessels.
Built with the people who work the water.
We want to hear from anyone who can help shape and test Sentinel in real marine environments.
