Nautronix has secured an order from HHI, Korea to supply a NASNet^® DPR (Dynamic Positioning Reference) System which will be used on the Bollsta Dolphin drilling rig.

NASNet^® DPR is the ultimate position reference system for Dynamic Positioning; it also has the benefits of the well-known NASNet^® subsea acoustic positioning system and can be used either within pre-installed field-wide NASNet^® arrays, or as a localised positioning system. 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 4000m.

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, comments: “We are very pleased to have been awarded this contract to supply a NASNet^® DPR system, this is the first time it has been used on a drilling rig and we are really excited about where this can take us. It is a great testament to our technology, products and the investment Nautronix has made and I am delighted that such a well-known and respected company such as Dolphin Drilling and HHI have chosen NASNet^® DPR.”
