PIPELINE AND SPOOL PIECE MOTION MONITORING

Processing raw sensor data subsea and wirelessly supplying only critical information to the surface from a subsea asset is at the heart of our SMART systems. SMART (Subsea Monitoring, Analysis and Reporting Technology)
integrates a number of technologies to provide long-endurance monitoring of subsea infrastructure, including pipelines and spool pieces.

SMARTs can record a wide range of acceleration and angular rate in all axes. Processing this information subsea, and comparing it with customer-defined thresholds, ensures only the most important subset of information is relayed to the surface. Each unit can accommodate a wide range of sensors, such as pressure, temperature and strain gauges, to provide a one-stop remote monitoring solution.

BUCKLING, WALKING OR CREEPING

Buckling, walking or creeping of subsea infrastructure (mainly pipelines and termination assemblies) is caused by variations in the temperature and pressure characteristics of their multiphase contents. The impact of this undesired behaviour can be continually monitored using our Autonomous Monitoring Transponders (AMTs); low-power, long endurance automatic ranging systems that, when mounted on structures subject to movement, can range to a static reference array on the seabed and calculate any movement to subcentimetre-level accuracy.

Data collected can be readily sent through the water column using our highly reliable Wideband acoustic communication protocols, to a Dunker 6 transceiver mounted on a remotely operated vehicle (ROV), autonomous or unmanned underwater vehicles (AUV/UUV), manned vessel or autonomous surface vessel (ASV).

HIGH BANDWIDTH OPTICAL COMMUNICATIONS

SMART systems can be supplied with integrated BlueComm free space optical communication modems for those monitoring applications where large volumes of data need to be transferred. BlueComm can transmit data at rates in excess of 10 Mbps, making it possible to transfer large volumes of data faster using much less power, when compared to acoustic through-water telemetry.
