Magtrack is an outstanding cable tracking system that can accurately detect cable positions, track a cable in 3D, show burial depth and pinpoint fault locations. It can be used on all subsea power and communication cables, carrying an AC current supplied by a tone generator or even the cable load current.
Lightweight and compact, the system is still very robust with titanium sensors and a subsea electronics module (SEM) in titanium and carbon fiber.
Each Magtrack system comes with 4 small sensors which integrate 3-axis fluxgate magnetometers and inclinometers for easy installation and highly accurate positioning.
The SEM processes data from all sensors and transfers raw and processed data to the surface vessel.
Magtrack data can be further processed in a survey system together with other relevant information, such as the position of a remotely operated vehicle (ROV) and data from other survey instrumentation.
The Magtrack system uses two pairs of small, highly sensitive sensors.
This provides significant benefits:
Thanks to its highly accurate sensors, Magtrack can sense even small changes in magnetic fields.
As most cable faults result in a change of its magnetic field, starting at the fault and continuing onwards, Magtrack can sense this change and pinpoint the fault location with great accuracy.
Trenching
Installed on a trencher, the Magtrack system is a reliable tool for:
Since the Magtrack system provides burial depth information during trenching,
it reduces the need for documentation by an additional ROV survey.
