Our subsea asset monitoring systems are used for a wide number of low-cost, long endurance subsea monitoring applications. Operations can range from the simplicity of a single tidal gauge to the complexity of a large transponder network designed to monitor long-term trends in pipeline movement or seabed settlement. The autonomous functionality of the system enables it to operate for several years without human or system intervention. This removes the requirement and cost overhead associated with the presence of a surface vessel or subsea ROV throughout the monitoring period.
