Ashtead Technology underscores Sonardyne’s Fusion 2 LBL as the gold standard

Sonardyne’s leadership in underwater navigation and positioning has been further reinforced by a major new order for its Fusion 2 platform and 6+ technology from the global subsea solutions provider Ashtead Technology.

This investment increases Ashtead Technology’s rental fleet of Sonardyne Compatt 6+s to well over 1,000 units, underscoring Fusion 2 as the industry standard for subsea positioning and navigation.

By integrating Long BaseLine (LBL) and SPRINT INS into a single, streamlined platform, Fusion 2, supported by Sonardyne’s 6+ hardware, continues to redefine how offshore construction projects are executed.

Since its launch, Fusion 2 has been making operations easier, more accurate, safer and more efficient by unlocking efficiencies through techniques like Sparse LBL and SLAM calibration.

As well as Compatt 6+ and ROV Nav 6+ Ashtead Technology’s expanded fleet now includes SPRINT-Nav navigation systems, Nano transponders and RT 6 acoustic releases.

Together, these technologies form the most capable and compatible subsea positioning and navigation solutions available in their fleet, enabling the company to deliver unparalleled precision and efficiency to its customers.

“This investment underscores our commitment to providing customers with the most advanced subsea technology to support their critical offshore projects,” says Phil Middleton, Head of Survey & Robotics at Ashtead Technology.

“By expanding and upgrading our Sonardyne equipment pool, we’re not only enhancing our service offering but also reinforcing our position as a trusted leader in the offshore construction market. Precision and efficiency are at the heart of what we do, and these advancements ensure we continue to deliver exceptional value to our customers worldwide.”

“Fusion 2 represents five decades of pioneering innovation at Sonardyne, driven by our goal to make underwater operations simpler, safer and more efficient,” says Alan MacDonald, Head of Sales – UK, Europe and Africa, at Sonardyne.

“Ashtead Technology’s investment is a testament to the platform’s capabilities and its role in setting the gold standard for offshore operations. By adopting Fusion 2 and Compatt 6+, they are equipping customers with the tools needed to meet the demands of modern offshore operations with confidence. From subsea structure installation to pipeline monitoring, Fusion 2 enables safer, faster and more reliable offshore operations.”

Fusion 2’s advanced capabilities include full LBL support, real-time SLAM calibration for sparse arrays and wireless structure deflection monitoring.

These features significantly reduce transponder count, vessel time and operational costs while ensuring centimetric accuracy in subsea positioning.
