TGS selects Exail Gaps M7 USBL system to optimize offshore geophysical surveys

The Gaps M7 is a pre-calibrated USBL positioning system with an integrated Inertial Navigation System (INS), delivering precise subsea positioning from ultra-shallow waters to depths of 7,000 meters. 

With a 200° acoustic aperture, it enables true horizontal tracking for high-accuracy positioning, making it ideal for TGS’s demanding offshore surveys. Lightweight and pre-calibrated, the Gaps M7 ensures fast deployment, minimizing downtime and streamlining survey workflows. Its rugged design guarantees stable performance in harsh offshore conditions, supporting TGS in acquiring high-quality geophysical data while reducing project costs.

“We needed a solution that would provide reliable, precise and high elevation tracking of our magnetometer and sidescan sonar,” said Anders Landbø, Director Maritime Performance and Projects at TGS. “After testing other USBL system without satisfaction, we tried Gaps and then decided to invest in this solution as it exceeded our expectations, offering ease of use and exceptional performance. Its pre-calibrated setup and high accuracy in shallow waters have significantly improved the efficiency and reliability of our offshore operations, and we are confident it will continue to enhance our geophysical surveys.”

“We are excited to support TGS with the Gaps M7 USBL system,” said Carl Trollet, Regional Sales Manager at Exail. “This collaboration reinforces Exail’s position as a trusted partner for offshore operations. Delivering the precision, reliability, and efficiency needed to meet the complex challenges of subsea tracking, Gaps M7 will help TGS continue to push the boundaries of geophysical surveys in the most demanding environments.”
