Summary
An ROV technician received an electric shock while rerouting a tether, without injury. Energising the tether management system produced induced voltage in isolated conductors, while two earthing clips had become dislodged. The flash examines insecure earthing connections and recommends design improvements, high-voltage training and warning signage.
