Designed by Fathoms in consultation with UKAEA, Dounreay, to detect buried radiological particles in ground 50m below the sea surface, TROL (Tracked Remote Offshore Logging) is the world's first tracked robotic system capable of delivering gamma spectroscopy in real-time, the genesis of which developed from Fathoms diving and undersea systems technology. This short article examines how an integrated approach to science and technology can be managed through quality processes to deliver superior solutions.

The tracked ROV (Remote Operated Vehicle) is designed specifically to meet the challenging demands of real-time subsea particle detection. Positioning of the vehicle by the ultra-short baseline acoustic system was integrated with the surface support vessel's differential GPS navigation system to produce accurate positions of detected particles.
