Nautronix’s subsea positioning system for Aasta Hansteen

Nautronix, a provider of through water communication and positioning technology to the offshore industry, has secured an order to supply NASNet®, an underwater positioning system for Subsea 7.

The system will be used on the Aasta Hansteen field, which is located in the northern part of the Norwegian Sea approximately 300km west of Bodø, at 1,300m water depth. The field is developed by Statoil.

Nautronix will be supplying 16 Large Stations and 4 complete vessel systems which will go on hire in March 2015 for approximately 200 days and will be deployed for the first time in Norwegian waters where the water depth is significant and the weather conditions can be challenging.

NASNet® is a subsea positioning system which combines Long Baseline (LBL) and GPS concepts with the latest generation of signalling technology.

Nautronix says that the system employs a broadcast technique to provide true multi-user, accurate and reliable positioning in all water depths with no acoustic interference.

Mark Patterson, CEO for Nautronix, says “We are delighted to be supplying NASNet® to Subsea 7 and it is a significant order for Nautronix. This is the first time NASNet® has been in Norwegian waters and we are really excited about where this can take us. We have been focussing a lot of our efforts to win a major contract for NASNet® and this award is part of our strategic development within the company.”
