V-LIFE is a preventative and active 'healing' solution of low insulation resistance caused by water ingress.

Problem

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. Historically, subsea fault-finding interventions and the replacement of cables, equipment or even umbilicals have been the only solution to this problem.

Solution

V-LIFE operates as both a preventative measure and active ‘healer’ of insulation. The topside installed V-LIFE enabled V-LIM deploys an electro-kinetic and electrochemical process which minimises and mitigates the effect of water ingress into the insulation and increases the IR of the system. 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 recommendations.

V-LIFE is currently implemented on control systems supplied by five different OEMs. Widely used by 18 operators globally, V-LIFE is the leading alternative to subsea interventions.

Key Benefits

  • 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
  • V-LIFE “finds” the points of water ingress, no diagnostics required.
