Ethernet Pipe Profiling Sonar


As leading international marine engineers with inland, inshore and offshore capability, our clients often require us to profile flooded and silted shafts, tunnels, pipes and drains – often in hard to reach or toxic environments − for cracks, faults and other structural displacements.

The 1512 Ethernet Pipe Profiling Sonar fitted to our fibreoptic Seaeye Falcon ROV offers us a cutting-edge acoustic method to accurately profile the interiors of liquid filled pipes or boreholes over long tether lengths. This method does not require draining of the pipes as with camera surveys, therefore providing accurate quantified data which could not be obtained from a camera display alone.



The Ethernet Interface Unit connects to the host PC running under the Windows operating system. The Ethernet Interface has inputs for a cable payout encoder so that the distance travelled may be displayed to 0.1m resolution allowing accurate determination of where flaws exist in the pipe relative to the deployment position. The Ethernet Interface is powered from the AC mains supply and is electrically isolated from the supply generated for the underwater scanner.

This technical capability is especially valuable in Victorian and other subterranean brick-built environments where small, single brick movements can remain undetected by visual non-acoustic profiling equipment.

Features include: 

  • Real time continuous scanning over a full 360 degrees in 1 sec

  • Windows user-friendly software with Ethernet connection

  • Direct capture to hard disk for high resolution image save and restore

  • Dual tracking cursor for accurate on-screen measurements

  • Internal Pitch and Roll sensors

  • Quadrature cable counter interface

  • Built in 500m cable drive with fibre-optic system upgrade

  • Automatic profile detection and output in ASCII format for import into third party 3D modelling software.

With our Reach Robotics tooling increasing, we purchased the Bravo Hub to allow us to easily power, add and remove items with minimal reconfiguration time. Plus our Falcon is limited to one ethernet port on the multiplexer and very little space in the VJB to accommodate additional devices. The Bravo Hub contains a subsea switch allowing us to run multiple ethernet devices on the machine simultaneously via the single ethernet port.


We also own a Hydro-300 photogrammetry system for underwater 3D modelling requiring gigabit speed, and a 24V ‘Orphie’ low-visibility IP camera. The team at Reach made some custom modifications to our Bravo Hub, increasing the speed of the switch to Gigabit and giving us both 24V and 48V outputs; this sort of collaboration has certainly set Reach Robotics apart as a supplier.


With the Bravo Hub and tooling skid we now run our Blueview sonar, Orphie camera, Hydro-300 Photogrammetry camera, the Bravo-3, Bravo-5 and its accompanying IP wrist camera simultaneously at up to gigabit speed.
