Nautronix to Supply DPR System for Dolphin Drilling Rig
Nautronix has secured an order from HHI, Korea to supply a NASNet Dynamic Positioning Reference (DPR ) System which will be used on the Bollsta Dolphin drilling rig.
NASNet DPR is a position reference system for Dynamic Positioning that also features the benefits of the NASNet subsea acoustic positioning system and can be used either within pre-installed field-wide NASNet arrays, or as a localized positioning system. According to Nautronix, the system provides robust mitigation against many of the risks associated with both acoustic and satellite positioning systems, allowing multiple users to benefit simultaneously from the same array with no risk of interference. NASNet DPR uses cutting edge acoustic technology combined with a user-friendly interface to provide high speed position updates and stable positioning in water depths up to 4,000m.
Graeme Murray, Managing Director of Dolphin Drilling said, “We are delighted to be using a NASNet DPR system on our new build, the Bollsta Dolphin. Dolphin Drilling is very supportive of this new technology and sees the significant advantages it can give to our customer. The system will give us fast one way, multi user acoustic positioning which will give us real opportunities to expand our subsea capabilities and redundancy for any loss of GPS due to scintillation.”
Mark Patterson, CEO of Nautronix pointed out that this contract marks the first time the NASNet DPR system has been used on a drilling rig.
