Sonardyne to support AUV programme

Sonardyne Asia Pte. Ltd’s marine robotics technology has been selected to help navigate a new autonomous underwater vehicle (AUV) that was developed by PTT Exploration and Production Public Company Limited (PTTEP) and Kasetsart University (KU).

The PTTEP-KU joint programme ordered one of Sonardyne’s SPRINT inertial navigation systems (INSs) and Syrinx Doppler Velocity Log (DVL) that will be integrated on a 4000 m rated, long endurance AUV that is being built for applications such as pipeline maintenance and oil spill detection.

Sonardyne’s SPRINT technology makes use of aiding from data sources including acoustics, DVL and pressure sensors to improve the accuracy, precision and integrity of subsea vehicle positioning over long distances.

As part of this research programme, KU will be the first academic institution in the region to own Sonardyne’s new, third generation SPRINT, which supports dual gyrocompass and INS operating modes, allowing AUV pilots and survey teams to utilise its navigation output simultaneously.

Syrinx DVL provides tightly integrated beam level aiding for SPRINT, even if one or two DVL beams are unavailable. It is able to operate at altitudes up to 50% higher than conventional 600 kHz DVLs with the high resolution performance of a 1200 kHz DVL, all whilst navigating over undulating and challenging terrain of any type.

Commenting on the order, Daniel Tan, Regional Sales Manager for Sonardyne in Singapore, said: “The marine robotics team at KU are designing a vehicle that will be capable of conducting pipeline inspections over distances of 100 km without any external position aiding. Reliable, survey grade navigation data will be essential to the success of its missions and this is where our all-in-one acoustically-aided INS solution comes in. SPRINT and Syrinx are proven to deliver class leading performance – as good as a fraction of a metre over many kilometres travelled.”
