Nautronix deploys NASnet array at Aasta Hansteen

Nautronix has announced that the NASNet^® array in Statoil’s Aasta Hansteen field is fully operational and awaiting first field construction. Last year Nautronix secured an order with Subsea 7 to supply 16 NASNet^® stations along with a wet-stored spare station and three additional MTrx beacons to provide QC capabilities.

Subsea 7 collected the full equipment spread in February, over three weeks earlier than scheduled, and the Subsea 7 construction vessel Havila Subsea was mobilised in Sandnessjøen, Norway on the 25^th February in preparation for the offshore installation. Despite challenging weather conditions in the Aasta Hansteen field, all 17 stations were successfully deployed to the seabed, tested and boxed-in (calibrated for position). The actual average installation time per station was less than six hours, which included calibration and testing.

Subsea 7 and Statoil said, “we’re very pleased with the progress and the positioning accuracies witnessed so far”. This is the first time NASNet^® has been used on a Statoil project in Norwegian waters, demonstrating Statoil’s desire to promote cost-effective technologies. The coming months will see the system working to its full potential. Mark Patterson, CEO for Nautronix says, “this is a key project for NASNet^®, and we are delighted to be working with Subsea 7 and Statoil. As the subsea industry looks to reduce costs, companies are looking at more cost effective and accurate acoustic positioning systems and, as a life-of-field system, NASNet^® delivers on both fronts.”
