Underwater technology specialist Sonardyne has introduced Observer, a new monitoring system designed to provide real-time integrity intelligence for offshore energy infrastructure.
Observer integrates high and low frequency motion and position monitoring with in-built analytics and wireless communications. By delivering live data on asset behavior, the technology allows operators to identify and address environmental challenges — such as pipeline expansion, contraction, and flow-induced vibration — before they escalate into significant failures. This proactive approach aims to lower operational risk, reduce intervention costs, and extend the functional life of subsea assets.
Built to operate at depths of up to 3,000 meters, the unit is ROV-deployable and capable of interfacing with a wide range of third-party sensors. The hardware is designed for long-term placement, with a deployment life of up to 10 years. It is intended for use across the entire water column, covering infrastructure including pipelines, risers, moorings, umbilicals, and wellheads.
Frank Rose, Business Development Manager – Subsea Asset Monitoring at Sonardyne, stated, “Observer shows asset integrity managers how their subsea assets are really behaving, not how they hope they are, with an easy to deploy solution that provides high quality data. Observer changes that with an off-the-shelf, versatile and user configurable product. It reveals asset behaviour, in real time, without adding operational complexity. This gives operators the confidence to act early, reduce risk and avoid the unexpected downtime that have long challenged offshore operations.”
The system is user-configurable, allowing asset managers to maintain direct control over parameters, while data offloading remains available on demand through Sonardyne’s established underwater communication protocols. Drawing on five decades of subsea expertise, the company developed the tool to provide teams with the visibility required to make informed choices regarding safety and operational continuity.
The technology is making its debut at the Subsea Tieback Forum & Exhibition in New Orleans this week at booth #329. It will also be featured at Oceanology International in London the following week, where the team will be present at stand F300.
