A new technology for the rejuvenation of subsea umbilicals and distribution equipment with insulation resistance degradation.
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 developed by Viper Subsea, 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.
