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.

Increases IR Without Subsea Intervention.

Recovers Multiple IR Failures Throughout The System.

Extends The Life of Failing Umbilicals and Electrical Distribution Equipment.

‘Buys Time’ Whilst a New Umbilical Is Procured.

Used As An Alternative to Installing New, Costly and Long-Lead Time Umbilicals.

Used To Delay Early Field Abandonment.

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.
