Nautronix to supply its NASDrill RS925 positioning system to Rowan’s third new ultra-deepwater drillship
has been awarded another
contract to supply NASDrill RS925 deepwater acoustic positioning system, for
Rowan’s third new ultra-deepwater drillship.
The vessel will be constructed at
Hyundai Heavy Industries shipyard in Ulsan, Korea and will be based on a
Hyundai Gusto P1000 design. It will be completed in the fourth quarter of 2014.
Nautronix says it received this order
through a well-known Norwegian DP supplier who is supplying their Dynamic Positioning
System on the vessel.
It’s the third order that the
marine technologies solutions company has received for the Rowan fleet,
Nautronix says. Vessels one and two are equipped with Nautronix’s NASDrill
Nautronix says its NASDrill RS925
system has been designed specifically to meet the requirements for a reliable,
stable DP and position reference system for demanding offshore operations, in
particular deepwater drilling vessels.
NASDrill RS925 combines the two
most accurate deepwater acoustic positioning technologies — Short Baseline and Long Baseline — to calculate multiple independent position
solutions providing reliable, repeatable input to the vessel DP system; with
SBL mode providing accuracies of 0.15 percent slant range and LBL mode
providing accuracies up to 1m RMS independent of water depth.
“We are delighted to be supplying Rowan Companies,
Inc. with their third NASDrill RS925 positioning system for their new vessel,”
said Mark Patterson, Nautronix CEO, in a company press release. “This clearly
demonstrates Rowan’s confidence in our NASDrill product.”
As with all Nautronix leading
commercial acoustic systems, NASDrill RS925 utilizes Nautronix proprietary ADS2
(Acoustic Digital Spread Spectrum) broadband signalling technology which has
been proven with over ten years of successful subsea operations, to provide
superior accuracy, repeatability and reliability for dynamic positioning of
vessels during deepwater drilling operations.
