CableFish

CableFish® is a low cost, low risk solution for monitoring submarine cable installation. The system operates effectively in shallow or high flow environments, conditions in which ROVs are rendered ineffective. CableFish®  can be operated in automated mode, such that it will automatically maintain a set altitude above the seabed.  The system is controlled and monitored via a PC connected via an ethernet connection.  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 adjusted to suit a wide range of cable sizes.  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.
