Recovering the Electrical Integrity of Subsea Circuits.

V-LIFE is a preventative and active ‘healing’ solution for low Insulation Resistance (IR) caused by water ingress.

The most common cause of subsea electrical failures is the ingress of water into the cable insulation, which decreases the Insulation Resistance (IR) and may produce short circuits or leakage to the earth. These faults often lead to loss of power and/or communications to subsea equipment and potentially halt production from subsea wells.

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. For over a decade, V-LIFE has been helping operators around the world to avoid costly umbilical replacement, mitigate loss of production, and maximize asset yield by extending the life of subsea control systems. Widely used by 30+ operators across six continents, V-LIFE is the leading alternative to subsea interventions.

Used to delay early field abandonment.

Increasing Low Insulation Resistance.

The V-LIFE effect is achieved by the application of a low voltage passivation signal, which generates and sustains a solid precipitate at the location(s) 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 200x.

A V-LIFE application involves the installation of a V-LIM line insulation monitor (the hardware) and enabling its V-LIFE passivation signal by uploading 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.

Providing a 200 Times IR Increase for Operator in the Gulf of Mexico

In this case study, discover how V-LIFE was used to avoid a threat to the continued production of a subsea production control system, resulting in a 200 times increase in insulation resistance (IR) within a week. Six months later, the channel continues to provide strong and consistent IR results; providing a value-added solution.
