The Orion underwater utility survey system brings the power of model-based processing to cable and pipeline Depth of Burial (DOB) surveys.
The method is based on the optimization of data from multiple sensors against a physical model of the magnetic field expected from a utility line carrying an AC tone (actively applied or passively present). System accuracy is estimated and presented in real-time.
Magnetic field distortion due to co-linear underwater conductors can occur when multiple pipelines share a right of way, or multiple wind farm power cables are closely spaced at landfall. The Orion system self-identifies these errors and presents them as confidence intervals on the measured Depth of Burial.
In the 4 or 6 sensor configuration, Orion can decouple this distortion from the target pipeline or cable, resulting in a more accurate Depth of Burial estimate, with an improved confidence interval.

Precise Data Collection in Adverse Conditions
Specifically designed for work in less-than-ideal circumstances on small survey boats and inflatable watercraft, the HYDROTRAC™ II offers compact portability and the confidence of knowing you’re using a proven Odom product.
It is completely waterproof and comes equipped with the same advanced features you’ve come to trust and depend on in Odom echo sounders.
Underwater Pan & Tilt units with absolute positional feedback & low backlash harmonic drives
3000m rated, oil compensated, compact & rugged Moves in both axis simultaneously.
High accuracy 1° or 0.1°absolute positional feedback Telemetry or voltage control.
Anodised aluminium or stainless steel housings Integral mounting bracket.
Optional ‘splat-cat’ mounting bracket and pole mount interface plate for multibeam sonar application.
The Signature500 ADCP is designed for flexibility. It measures current profiles at up to 8 Hz sampling frequency. It can also measure direct vertical velocity profiles, wave height and direction, and acoustic ranging to ice. The center beam also functions as a biological echosounder, enabling high-resolution measurements of biomass in the water column. All these features can be combined using Nortek’s patented concurrent mode technology.
DeepWater Buoyancy understands the value of data recovery, as well as, ADCP technology, oceanographic operations and what it takes to supply products that ensure success.
Manufactured from high-performance DeepTec® syntactic foam, adjustable urethane and UHMW instrument clamps, and 316L stainless steel and titanium hardware, DeepWater Buoyancy’s ADCP Buoys are designed to outperform and outlast conventional mooring flotation.
