applied acoustics provides subsea positioning and acoustic technologies for unexploded ordnance (UXO) detection and seabed survey operations supporting offshore construction projects. The company’s systems assist in identifying UXO and other seabed anomalies ahead of offshore infrastructure installation.
UXO surveys are a key part of offshore development activities including offshore wind farms, subsea cable routes, and port expansion projects. Buried military munitions and other subsea hazards can present risks to construction activity, making accurate positioning and imaging data essential for locating and identifying potential threats.
To support these operations, applied acoustics combines vessel-towed sensors with magnetometers, gradiometers, and side-scan sonar systems to create a detailed picture of the seafloor. The company’s technologies are suitable for both shallow-water and deep-water survey operations.
Pyxis INS + USBL and Nexus 2 systems provide accurate underwater positioning through features including MiQ bi-directional telemetry, Multi-Fire common interrogate capability, and Sigma 2 digital spread spectrum transmission technology.
Pyxis INS + USBL
Pyxis INS + USBL combines applied acoustics’ USBL technology with an advanced inertial navigation system (INS), creating an inertially aided Ultra Short Baseline system capable of highly accurate subsea tracking with survey-grade performance.
Nexus 2 Max, Model 2698.
The system is suited to offshore survey applications requiring reliable underwater positioning and tracking performance.
Nexus 2 Max, Model 2698
The Nexus 2 Max, Model 2698, is engineered for rapid deployment and straightforward operation while incorporating a number of enhancements over the original Nexus 2 system.
Key features include:
- UDP inputs for vessel sensor data including GPS, gyro, and MRU
- Enhanced serial protocol support for RS485, RS422, and RS232
- NTP time synchronization and data interpolation capabilities to improve data quality
- Up to four responder outputs
- PPS Out and Sync In
- Remote access and control functionality
- Diver charts and reporting
Acoustic Positioning Beacons
applied acoustics manufactures a range of acoustic positioning beacons covering shallow-water through deep-water applications. The portfolio includes compact micro beacons for restricted environments as well as seabed beacons for operation in deep, noisy, and challenging subsea conditions.
MiniPod Positioning Systems
The MiniPod range provides GNSS-based positioning capability for operations within challenging transition-zone environments.
Geophysical Survey Systems
applied acoustics’ geophysical survey systems are engineered for marine survey operations requiring high data quality, operational flexibility, and dependable performance.
The company’s portfolio includes boomers, sparkers, hydrophones, seismic streamers, CSP energy sources, and sub-bottom profiling software designed for geophysical, engineering, and geotechnical survey applications.
Offshore Survey Applications
applied acoustics technologies are used across offshore renewables, port and harbour surveys, and UXO survey operations. The company also supplies CSP units, sparkers, hydrophones, and the HYPACK® SBP Workstation.
