CableFish®

CableFish® is a low cost, low risk solution for monitoring submarine cable installation. The system is designed to operate in up to 6 knots of tidal flow.  In these conditions cable installation is notoriously difficult and ROVs are rendered ineffective. CableFish®  uses instruments mounted on a cable mounted carriage and a fibre optic umbilical to provide video and GPS coordinates of the cable touch down point in real time.  The system can be readily adapted to operate from most cable installation vessels.  It can also be easily modified to accommodate a wide range of sensors. Call us to discuss how CableFish®  can be used to support your submarine cable installation operations.       CableFish
