Riser Profiling System

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.

Up to 10 DPTi transponders are deployed up the riser. Each transponder is fitted with the following sensors:

-High-resolution dual axis inclinometer

-Water temperature

-Pressure and depth

-Optional single point Doppler current meter (speed, direction)

At a user-defined update rate, inclination, current speed and direction, pressure, temperature measurements are requested from

each transponder. The transponders reply using Sonardyne's Wideband 2 acoustic signals to the vessel's acoustic transceiver. All data is processed, logged and displayed graphically and numerically on the topside computer software for instant analysis by the operator. The operator can also set an alarm to activate when the calculated riser angle exceeds a predefined limit.

The Riser Profiling System supports Sonardyne's new 6G® product family, Sonardyne Wideband® 2 acoustic signal technology and previous generation positioning components.

Also available from Sonardyne is a Marine Riser Angle Monitoring System (MRAMS). This uses a pair of DPTi transponders fitted to a BOP and riser lower flex joint to prevent critical bending.
