The V-LIFE effect is achieved by the application of a low voltage passivation signal to the faulty line which through an electro-kinetic and electrochemical process generates and sustains a solid precipitate at, and only at, the location or locations in the subsea circuit where seawater has ingressed.
The precipitate produced is electrically insulating and its propagation at the source of the fault results in an increase in the Insulation Resistance of the circuit often by more than 100x. V-LIFE is currently implemented on control systems supplied by six different OEMs. Widely used by 30 operators globally, V-LIFE is the leading alternative to subsea interventions.
