Sonardyne delivers acoustic positioning simulator to Brazilian training facility

Offshore staff

YATELEY, UKSonardyne Brasil Ltda. has supplied equipment that simulates acoustic positioning operations on dynamically positioned (DP) rigs and ships to GE Power Conversion for its new training school in Macaé.

The Sonardyne Marksman hardware and 6G Sim software will be used to provide student DP officers with an understanding of the role acoustic positioning has in assisting a vessel to remain in a specified location while underwater operations are being conducted.

The Marksman system calculates a vessel’s position relative to an array of transponders deployed on the seabed. The technique is known as long and ultra-short baseline (LUSBL) and it provides an accurate and highly stable position reference for DP vessels where remaining in a specified location is a critical operational requirement.

The Sonardyne equipment now installed at GE’s Macaé facility includes a Navigation PC running the Marksman LUSBL application, along with 6G Sim, a software application that simulates an array of transponders on seabed transmitting signals up to the surface. The system has been interfaced with GE’s C-series DP desk.
