Noble Corporation has selected acoustically-aided inertial navigation technology from Sonardyne for its ultra-deep water drillship Noble Globetrotter I.
The Marksman DP-INS system is being used to provide a high integrity, independent subsea position reference for the vessel’s GE DP3 dynamic positioning (DP) system.
Built in 2011, the Noble Globetrotter I is smaller than a conventional drillship but has the same operational capacity.
The equipment supplied to Noble Corporation included Sonardyne’s vessel-fitted inertial sensor and bridge software. Although DP-INS is compatible with HPR systems from other manufacturers, for this installation, it was interfaced with Noble Globetrotter I’s existing Sonardyne acoustic reference system using the same bridge workstation.
“We’re delighted that Noble has once again chosen to invest in our technology to support their vessel positioning and drilling activities,” said Dan Zatezalo, technical sales manager at Sonardyne in Houston.
