Asker, 15 July 2021: Argeo was contracted for a planned electrification project for a major Norwegian O&G customer. More than 120km-long corridor survey was performed by Argeo using Autonomous Underwater Vehicle (AUV) in less than a week. Performance per 12 hr missions with more than 70 line kilometres proves the efficiency of the technology compared to traditional ROV surveys. With water depth ranging from a few tens of meters to 600 meters in the surveyed area, 20- to 50-cm resolution bathymetric maps along with 5 cm-resolution HiSAS imagery and backscatter mosaics provide exceptional support in underwater construction projects such as laying of cables and pipes, anchoring etc. High-quality digital elevation models integrated with sub-bottom profiling provide valuable 3D-information about the surveyed corridor allowing to make sound decisions for geotechnical tests and further construction operations.

Mr. Trond F. Crantz, CEO of Argeo commented as follows:
“I’m very pleased with the exceptional results from this project, which is a testament to the brilliant skills of our GEO-team and yet again proves to our demanding clients how very accurate digital models of a project can save millions of Dollars in the later design and construction phase. The efficiency from unmanned autonomous acquisition through a streamlined data management workflow proves our concept of Faster, Better and Greener solutions at a lower cost for our customers and we have more exiting news to be released during our Q2 presentation on the development of this very promising technology.”
