Sonardyne and AMOG Partner on Integrated Subsea Asset Monitoring Service for Offshore Energy Infrastructure

Underwater technology specialist Sonardyne has signed a memorandum of understanding with advanced engineering company AMOG to deliver a complete subsea asset monitoring service for offshore energy infrastructure operators, combining Sonardyne's underwater monitoring, positioning, and communication technologies with AMOG's engineering assessment expertise. The partnership is already working on a near real-time mooring monitoring system for a European floating offshore wind project, with the combined solution targeting floating offshore wind and oil and gas moorings, pipelines, and risers.

 

Strategic Rationale for the Partnership

 

The MoU brings together two complementary capabilities that address different but interdependent elements of subsea asset integrity management. Sonardyne contributes the hardware and data acquisition layer through its underwater sensing, positioning, and communication systems, while AMOG contributes the engineering assessment methodology needed to translate raw monitoring data into actionable operational intelligence. The combination addresses a persistent gap in how subsea asset monitoring is delivered to operators, who have historically received sensor data and engineering assessments from separate providers without a structured framework for integrating the two into a coherent operational picture. The single end-to-end solution model reduces the coordination burden on operators and creates clearer accountability for the quality of insight delivered.

 

Observer Technology and Edge Analytics

 

Central to the offering is Sonardyne's Observer wireless intelligent subsea asset integrity monitoring solution, which features high and low-frequency motion monitoring capability alongside third-party sensor integration and internal edge analytics. The edge analytics capability is commercially significant because it enables data processing to occur at the sensor rather than requiring all raw data to be transmitted to surface systems or shore-based servers for analysis. Processing at source reduces bandwidth requirements, improves the timeliness of anomaly detection, and supports more reliable monitoring in environments where communication windows are intermittent. The wireless architecture reduces the installation complexity associated with cabled monitoring systems and supports more flexible deployment across varied subsea infrastructure configurations.

Engineering Assessment and Operational Insight

 

AMOG director Hayden Marcollo, who specialises in moorings and vortex-induced vibration engineering and analysis, has framed the combination of high-quality subsea data processed at source with advanced engineering assessments as a pathway to more actionable near-real-time insight into the condition and behaviour of critical subsea infrastructure. The ability to detect anomalies earlier, improve understanding of loads and motions, and make more informed decisions around inspection, maintenance, and integrity management represents a meaningful improvement over existing approaches that rely on periodic physical inspection supplemented by limited real-time monitoring. For operators managing ageing offshore assets where life extension is commercially attractive, the combination of continuous monitoring data and rigorous engineering assessment provides the evidence base needed to support safe and defensible decisions about extended operational life.

 

Floating Offshore Wind Application

 

The partnership is already engaged on a near real-time mooring monitoring system for a European floating offshore wind project, providing an early operational reference that strengthens the credibility of the combined offering in a growing market. Mooring system reliability is one of the most critical determinants of floating wind project economics, and the ability to monitor mooring behaviour continuously and to assess the condition of chains, connectors, and anchoring systems in near real time provides operators with a substantially improved integrity management framework. As floating offshore wind moves toward commercial scale deployment, the demand for robust subsea monitoring and engineering assessment services is expected to grow, and early positioning in this segment provides both companies with a differentiated capability at a pivotal stage of market development.

 

Implications for Subsea Asset Life Extension

 

The life extension application of the combined monitoring and assessment service is commercially relevant across the broader offshore energy sector, where the economics of continued production from mature assets frequently depend on the ability to demonstrate structural and mechanical integrity beyond original design life. Continuous monitoring data from Observer, combined with AMOG's engineering analysis of loads, fatigue accumulation, and structural behaviour, provides operators with a more rigorous and defensible basis for life extension decisions than periodic inspection alone. The reduction in unplanned downtime associated with earlier anomaly detection further strengthens the commercial case for integrated monitoring, since production interruptions on floating production systems and floating wind platforms carry very high opportunity costs.
