The Imenco Nautronix NASDrill RS925 is an advanced subsea acoustic positioning system combining long baseline (LBL) and short baseline (SBL) operating modes. It is designed specifically to meet the dynamic positioning (DP) reference requirements of ultra-deepwater drilling vessels by providing independent LBL and multiple SBL outputs to the DP system up to 1Hz.
The NASDrill vessel systems are acoustic positioning and tracking systems developed to meet the demanding requirements of the drilling and DP sensor markets. The systems utilise acoustic digital spread spectrum (ADS2) signalling technology, providing reliable and robust acoustic positioning in deepwater and challenging environments. NASDrill USBL is an advanced ultrashort baseline (USBL) acoustic positioning system which accurately measures and displays the position of a surface vessel relative to subsea beacons or locations. It is designed to meet the positioning requirements of drilling operators relating to well, riser and remotely operated vehicles (ROVs) providing reliable acoustic riser angle data. At Imenco, we know that the safe operation and reliability of our acoustic positioning products are important to our clients. As a result, we provide vessel system upgrades in order to manage obsolescence and benefit from the latest digital technology.
