Why Fetch AZA is perfect for your operations

Your Fetch AZA system offers a comprehensive solution transforming your ocean monitoring operations across multiple applications, including environmental surveys, seabed deformation monitoring and low-cost in-situ ocean surveillance. Unlike traditional pressure sensors, which suffer from drift over time, the Fetch AZA technology autonomously recalibrates in-situ.

A unique control system periodically cycles the pressure sensor from ambient seabed pressure to near-zero, enabling comparison to a highly accurate low-pressure reference sensor for calibration. The reference sensor is never subjected to ambient pressure and is accurate to changes of less than a millibar, or about 1cm of head of water.

The sensors are low power, allowing for long endurance deployments, and provide time-stamped data, which is often critical to your commercial or scientific objectives. With their in-built data storage and high-speed modem capacity, they can support your data collection and harvesting using a wide range of other Sonardyne and third-party sensors (High precision temperature and sound velocity as well as inclination) and are compatible with any Sonardyne 6G equipment, including Ultra-Short BaseLine (USBL) systems and modems.

For science

These capabilities have created an instrument that revolutionises seabed measurements across ocean science and the commercial sectors. Scientists can now undertake measurements, critical to understanding tectonic processes, at a resolution they’ve never been able to achieve before.

For business

In the commercial sphere, Fetch AZA meets upstream production companies’ long-term goals of measuring 1 cm/year of vertical movement across their energy fields. These fine-scale measurements provide a powerful tool for proactive reservoir management throughout their lifecycle. This is a key enabler for maximising economic recovery.

Its remote capabilities represent a significant operational advantage, as data can be retrieved using Uncrewed Surface Vessels (USVs) from over-the-horizon locations, eliminating the need for expensive crewed vessels and reducing your costs, personnel risks and environmental impact.

This combination of remote operation, sustained accuracy, and precise repeatability makes the Fetch AZA an ideal choice if you are seeking a reliable, cost-effective ocean monitoring solution.
