V-LIFE is proven technology, installed by 18 operators worldwide and acts as both a preventative and active 'healing' measure of low insulation resistance caused by water ingress.


The most common cause of subsea electrical failures results from the ingress of water into the cable insulation. Such failures may produce short circuits between conductors and/or current flow from live conductors to earth. Subsea interventions to replace cables, equipment or even umbilicals have been the only solution to this problem.

The V-LIFE acts as both a preventative measure and an active 'healer' to low insulation resistance. By deploying an electro-kinetic and electrochemical process, the V-LIFE can minimise and mitigate the effect of water ingress into the insulation. It is a standalone device that can be readily retrofitted into topside equipment or provided as a function of the V-LIM. The V-LIFE also monitors the insulation resistance, voltage and current of the subsea umbilical with high accuracy and can display the IR graphically in real time giving a visual indication of the effectiveness of the system. Online data recovery allows Viper to optimise the configuration data and provide regular integrity reports.

Key Benefits

  • Reverses the effects of water ingress into electrical cables and equipment
  • Can extend the life of failing umbilicals
  • ‘Buys time’ whilst a new umbilical is procured
  • Used instead of installing a new umbilical
  • Can be used to postpone field abandonment
  • Can increase technical margins to allow additional wells to be added
  • Can rejuvenate other subsea distribution equipment and components 

Five Years of V-LIFE


Key facts

  • Installed by 18 operators globally
  • V-LIFE increases the insulation resistance of the umbilical and subsea electrical distribution system
  • The V-LIFE continuously monitors the line and provides data on its operation and its condition
  • Can be proactively fitted by installing the V-LIM, line insulation monitoring device and V-LIFE activated when required
  • Operational since July 2012, the deployments have shown significant improvement in insulation resistance after just a few months use and have been stable since
  • A scientific breakthrough
