The V-SLIM is the subsea deployed node in a V-IR System that identifies and locates electrical faults
With current subsea architectures, subsea power and communications are distributed from a single umbilical to many subsea control modules, each acting as a power consumer and communication node. The electrical distribution network comprises many electrical cables and connectors all configured in a multi-drop layout with multiple 'spurs' or 'legs'.
Currently there is no way of monitoring the electrical integrity of each of these cables and connectors individually, and if there is a failure then the only way of fault finding is through intensive intervention and part replacement until the fault disappears. Such an approach is very costly and is reactive only.
The V-SLIM enabled electrical flying leads are installed at strategic subsea locations, and any associated degradation of the subsea electrical distribution network can be measured and located with analytics. The patented V-SLIM measurement technology does not rely on any in-line electronics or switches. The lines being monitored pass straight through the unit.
Communication between units and to topside are accomplished using either:
• Viper V-NET line to earth interface
• SIIS level 3 Ethernet interface.
Host system communications are unaffected. When a fault occurs its location is evident without the need for diver or ROV operations.
An external diver deployed V-WAND is available as an alternative data recovery and firmware update option.
