Sonardyne’s Riser Profiling System provides operators with a wireless real-time vertical profile of current speed and direction, temperature and inclination of risers deployed from drilling or production vessels. The system can be used stand alone or integrated within Sonardyne’s Marksman acoustic positioning system which is used as a Dynamic Positioning (DP) reference.

Riser sensor data is measured by Sonardyne’s latest 6th Generation (6G®) DPTi transponders clamped onto the riser during deployment, or installed via ROV. The information is transmitted wirelessly using proven acoustic telemetry up to a transceiver on the vessel, eliminating the need for expensive umbilical cables to fitted up each riser.
