6G & Wideband 2
These unique technologies help make SMART smart; delivering long endurance, intelligent asset monitoring and secure data delivery.
Made for you
Nearly all asset monitoring surveys are unique in their requirements. SMARTs can be engineered to meet your project's exacts needs and budget.
SMART delivers the precision, reliability and flexibility you need for analysing short and long-term trends in structures, pipelines, spoolpieces and risers such as creep, bending and strain.
With a wide range of sensor options available, we can configure a system to meet the specific monitoring needs of your offshore assets.
A typical survey includes multiple SMARTs deployed on the structure under investigation; PLET, pipeline, template or riser. Our service includes designing and fabricating custom brackets to mount SMARTs onto your infrastructure – including making them ROV-friendly to enable fast and efficient installation and removal.
SMART includes digital and analogue inputs which can be configured to connect to multiple data sources. Internal sensors are available for motion measurement including; accelerometers, angular rate sensors and inclinometers, along with standard and high precision pressure and temperature sensors. External sensors that can be interfaced include; pressure sensors, strain gauges and ADCPs. For more bespoke applications, custom interfaces can be created to link to instruments from corrosion monitors to vibration measurement tools.
Onboard data logging and analysis
A low power data logger is a key ingredient of SMART, enabling data received from external and internal sources to be securely archived using dual redundant storage. Where SMART goes beyond existing products, is in its ability to process raw data subsea to provide value added functions.
Onboard SMART is has a highly capable processor which can run sophisticated user specified algorithms, as well as simple data analyses such as Min/Max/Mean statistics and thresholding for alarms and critical event reporting. By reducing high bandwidth sensor data to small, critical packets, SMART enhances users’ knowledge of the subsea world. By efficiently managing power consumption, long deployment times can be achieved from the internal battery pack.
SMART uses our trusted Wideband 2 acoustic telemetry module for seafloor to surface communications. Operating in the Medium Frequency (MF) or Low Medium Frequency (LMF) band, there are options for omni-directional and directional transducers with high output powers for use in deep water and in challenging acoustic environments.
Utilising Sonardyne Wideband 2 advanced spread spectrum coding, SMART can transmit stored data at rates up to 9,000 bps to topside transceivers and modems including HPT 5000, Modem 6 Dunker 6.
Alternatively, SMART can be coupled via an Ethernet connection to a BlueComm high bandwidth optical communication link enabling larger quantities of data to be ‘harvested’ from ROV, AUV or USV. All logged data can be downloaded from safe storage via Ethernet when the unit is recovered.
The software to run your network of SMARTs is fully configurable and can run either on our Marine Computer or on a third party computer connected via a Sonardyne Surface Interface Unit (SIU). Users can choose to run standard software, which provides acoustic link configuration, diagnostics and a command interface to the SMART, with data passed on to third party software.
This option is attractive if analysis and display software is already available for the application or where the SMART is providing a wireless backup to a cabled system. Alternatively, our custom projects teams can adapt the standard platform to provide you with software that meets your specific requirements for managing and displaying data, including now remote, over-the-horizon command and control.

Deepwater data analytics – asset monitoring at the edge
Thousands of kilometres of pipeline, flowline, and interconnecting spool pieces are installed on the world’s sea and ocean floors. Monitoring and maintaining these vast networks of pipes can be challenging. Explore how Oceaneering provided the analytics they needed to monitor these pipes using our SMART technology.
Trendsetter Vulcan Offshore uses a SMART solution to monitoring wellhead fatigue
A reduction in subsea wellhead fatigue life was prevented through the use of a BOP Wellhead Fatigue Mitigation System supported by our Subsea Monitoring, Analysis and Reporting Technology (SMART). By enabling drilling operations using larger BOPs on older wellheads, operators are able to extend production and field life cost-effectively.
