A passive tracking and survey tool used on live AC or unipolar DC cables that are powered.

The Artemis sensors are set to look for 50/60 Hz or a harmonic from the live power transmission (residual in AC phase imbalance, or from AC-DC conversion).

Unlike alternative technologies on the market, Artemis uses a model-based technique looking at the 3D magnetic field properties to estimate the centre of the target/ magnetic field. This approach handles arbitrary slant angles much better, meaning the performance of the system is maintained even if the ROV moves off the cable.

Artemis Toned

Passive tracking/survey with the same configuration as Artemis Live

but used on cables with no or little power, or bipolar DC cables.

A tone is applied at the end of the cable (substation, turbine, etc.), and the Sensors set to look for the specific low-frequency AC tone.
