Recover the Electrical Integrity of Subsea Circuits.
V-LIFE is a preventative and active ‘healing’ solution for low insulation resistance caused by water ingress.
The most common cause of subsea electrical failures is the ingress of water into the cable insulation, which decreases the IR and may produce short circuits or leakage to earth. These faults often lead to loss of power and/or communications to subsea equipment and have the potential to halt production from subsea wells.
It has also been demonstrated that prolonged operation of subsea power circuits with particularly low Insulation Resistance can lead to the loss of copper from the conductor at the fault site which in turn can lead to the complete loss of operability of the system. Before V-LIFE became available expensive subsea fault-finding interventions and the replacement of cables, equipment and umbilicals were the only solutions to this problem.

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.
A V-LIFE application involves the installation of a V-LIM line insulation monitor (the hardware) and the enabling of its V-LIFE passivation signal by the upload of a software config file. V-LIM and V-LIFE can typically be installed and commissioned within 2 to 3 shifts offshore. The installation work is all topside. No subsea intervention is required.
Additional support is provided as part of the V-LIFE service in the form of condition reports, trend analysis and engineering recommendations.
V-LIFE is currently implemented on control systems supplied by six different OEMs. Widely used by 40 operators globally, V-LIFE is the leading alternative to subsea interventions.
Be V.SMART.
Be V-LIFE READY.
To ensure your system is V-LIFE ready, simply install one of our advanced insulation monitoring products V-LIM, V-LIM2 or V-SLIM; to provide enhanced monitoring; with increased visibility of the health of your subsea control system. You’ll also be future-proofing your system’s integrity with the ability to switch on V-LIFE to prevent faults and avoid risk to production and unplanned intervention.
Together, these solutions ensure systems are V-LIFE ready, with PlatformVi providing system health insights, tracking trends, quick decision-making and enabling automated IR recovery; allowing operators to prevent faults and actively maintain cable integrity.
