Offshore Survey Solutions for UXO Search and Cable Tracking


SENSYS offshore solutions are scalable for tethered, but ROV mounted effective seafloor investigations to survey and measure seabed for buried UXO or infrastructure.


The high sampling Fluxgate Magnetometer allow a seamless digital seafloor map to interpret for and detect suspicious objects and infrastructures.


Precise data matters to keep missions efficient, safe and properly documented.

To be sure offshore

Clients have incredible costs for operating vessel and crew offshore. Failure and going back to harbour is not an option. SENSYS offshore survey equipment needs to be and is more reliable than ever. We are your trusted partner!

Offshore Survey Campaigns

With the industry expanding into Offshore areas to generate alternative energy by wind farms, tidal power plants or the expansion of oil–conveying systems, the industry faces two major challenges. On one side an UXO clearance must be made before the laying of cable lines, installing basement and pylons for infrastructure. On the other hand, regular maintenance needs to be performed after the installation and commissioning of equipment to monitor dumping, disposal of objects on the routes or their displacement.



SENSYS Offshore Survey Solutions

SENSYS provides a range of survey systems installed on ROVs or mounted behind ROTVs or directly towed/tethered by vessel. The MX3D UW forms a compact, but scalable system using a small submersible data acquisition unit placed inside the ROV or ROTV to supply the sensors with power, gather measurement values and provide them with a fast Ethernet connection to the ROVs MUX or similar. As the SENSYS FGM3D Fluxgates are such small and light weight, they can be mounted in the most hydrodynamic way, adding no impact to buoyancy.


4 kHz Data Density for in-depth Data Analysis

Sampled with up to 4kHz and digitized by an 24Bit ADC, the MX3D UW generates a seamless track of measurements beyond fastest survey speed. At the same time, the SENSYS solutions are power savers, cost efficient and the system is intuitive to set up with no calibration needed as well as doing the data recording whilst operation. SENSYS ensures a complete tool box from recording, processing to interpreting the data to give instant feedback during the campaign making a spot or local area investigation as short and effective as possible.

The MX3D UW is integrated into the ROTV system MAGRAY as well as mounted to the SEARACK frame designed for ROV operations. If divers comes into game, SENSYS offers the DBL15 with a gradiometer probe to hold and an audible feedback forwarded to the divers head phone. With an optional data recording, documenting any diver operation is as simple as never before.
