Battery-powered subsea HPU for autonomous monitoring and control system

In order to monitoring the twist, tension, and torsion in the cables connected to an abandonment and recovery hook, as well as to control the opening and closing of this hook, Allseas approached Seatools with a request for a monitoring and control system.
As no cables for power and data transmission were allowed, Seatools had to develop an autonomous system. We met this challenging requirement by powering the system with a battery-powered subsea HPU, while acoustic modems enabled data communication.
