From array design to deployment support, data harvesting and processing, we provide you with a full subsea monitoring service.
Measuring millimetric movement matters
When your operations, assets and income stream are all based subsea, monitoring their movement, and that of the environment around them, matters.
Whether it’s seismic activity, pipe, riser or mooring movements, seabed deformation, or currents, temperature and turbulence around your assets, timely, reliable monitoring data can inform your operations, help to avoid accidents and save you money.

Seabed and seismic
Developed over more than a decade and in use globally by the energy sector, our ‘game-changing’ seabed deformation monitoring technologies offer critical new understanding of seafloor movement and its impact on installed structures and reservoirs, including those used for carbon storage.
What our tech can do for you
•10 Years – Long-term unattended deployment and monitoring of the seabed
•USV or AUV – Remote data acquisition for safer, greener survey operations
•9,000 bps – Fast and robust communications performance
•6000 m – Working depth, perfect for deepwater operations
Similar to seabed deformation, seismic movement monitoring is important for your ocean science and energy operations. Measurement of tectonic plate movements can inform scientific research and alert energy operators to potential hazards.
Currents
The water around your assets can affect their performance and longevity. Currents, temperature, turbidity and chemical composition can all play a part. Monitoring, whether short or long term, can inform your operational decision making. Developed using our decades of experience, our Origin acoustic doppler current profiler (ADCP) provides you with reliable, accurate and timely current and wave data. It’s built in acoustic modem gives easy access to data and rechargeable batteries give greater deployment lengths and quick turnaround redeployments.
During your operations, you can gather and transmit your logged data wirelessly, using our sixth generation (Sonardyne 6G®) acoustic communications platforms onboard unmanned surface vessel (USV) or autonomous underwater vehicle (AUV) platforms or from any crewed vessels using or Ranger 2 systems or Dunker 6 transceiver.
Structure and Pipeline
SMART delivers comprehensive subsea monitoring capabilities in a single, easily deployed instrument designed for extended offshore campaigns. This low-power system combines advanced data logging, onboard processing, and acoustic telemetry to provide real-time insights into the health and performance of your critical structures, pipelines, and risers. Customizable sensor configurations and ROV-compatible mounting options ensure seamless integration with your specific infrastructure requirements.
The system’s sophisticated onboard processor analyses data at source, converting high-bandwidth sensor inputs into actionable intelligence while smart power management maximizes deployment duration. Data transmission is flexible—retrieve information via industry-leading Wideband 2 acoustic telemetry operating at speeds up to 9,000 bps, or utilize high-bandwidth optical links for larger datasets. With configurable measurement intervals adjustable during deployment and dual redundant storage for secure data archiving, SMART provides the precision monitoring intelligence needed to optimize your offshore asset management strategy.
Wellbore monitoring
Acoustic Data Logger delivers reliable, long-term wellbore monitoring backed by over 30 years of proven field performance. This robust system reads multiple gauges at predefined intervals, securely stores data within corrosion-resistant super duplex stainless steel canisters, and transmits information acoustically on-demand to surface vessels. Compatible with both IWIS and non-IWIS gauge cards from leading manufacturers, the logger operates for up to three years at standard sampling rates, with extended deployments easily supported through external battery packs.
Engineered for versatility and durability, the system is ROV-portable to 3,000 meters depth, making it ideal for both short-term well appraisals requiring frequent readings and multi-year permanent installations on wellheads. Our latest 6G and Wideband 2 acoustic technology enables rapid, accurate retrieval of large data volumes at surface. For suspended or abandoned wells, our high-availability acoustic modems integrate seamlessly with third-party monitoring solutions, including electromagnetic and through-casing technologies, ensuring continuous data access throughout your well’s lifecycle.
Fetch
Fetch pressure monitoring transponder (PMT) instruments are subsea sensor logging nodes that measure long-duration seafloor movement, laterally and vertically. Fetch PMTs can take hundreds of thousands of highly precise, stable geodetic observations over long periods of time; safely log the data to internal memory; and, on command, wirelessly transmit it up to the surface.
With the addition of our in-situ pressure sensor calibration capability, Ambient-Zero-Ambient (AZA), we address the inherent drift that pressure sensors experience over time. That means your instruments can remain on the seabed, and generate accurate data, for up to 10 years – without any need for periodic retrieval for recalibration.
SMART – Asset monitoring and analysis transponder
SMART brings together low power electronics, data logging, subsea data processing and acoustic telemetry into a single, easily deployed instrument that’s suitable for a wide range of long duration, remote monitoring campaigns across energy and scienc.
• Battery options to support campaigns in excess of 10 years
• Can be deployed and recovered using ROV
• 3,000 m standard depth rating; options for 7,000 m
• Onboard logging and processing of data; offloaded acoustically on demand
• Built on our low power 6G hardware platform and Wideband 2 digital signal architecture for reliable acoustic performance in noisy conditions
Origin ADCP
Our Origin family of ADCPs represent the latest in cutting edge underwater profiling technology. Able to analyse mean currents, waves and turbulence, and integrate with external sensors to provide pH levels, temperature and other data, Origin delivers comprehensive, reliable and timely data sets for your underwater operations.
With on-board Edge data processing and built-in acoustic modems, Origin can also process and deliver your data in almost real-time. Available in two models, Origin 65 for deep water profiling and Origin 600 for near and inshore waters, there is an Origin ADCP to suit your operation.
Acoustic Data Logger
Built on more than 30 years of successful installations, Acoustic Data Loggers provide you with the power to read multiple gauges at predefined intervals, securely store the received information within the unit, then transmit it acoustically through the water column to the surface on-demand.
