Sonardyne’s Technology to Support Fugro’s Offshore Wind Operations

Sonardyne’s underwater positioning technology will support Fugro’s offshore wind operations in North America.

Leading geo-data specialist Fugro has chosen underwater positioning technology from Sonardyne Inc. for its upcoming offshore wind farm projects in North America

Fugro has ordered three Sonardyne Mini-Ranger 2 Ultra-Short BaseLine (USBL) underwater positioning systems, to support shallow water site characterization surveys, and a standard Ranger 2 for positioning geotechnical boreholes that will influence turbine foundation design and installation. In addition, Fugro has also ordered Wideband Sub-Mini 6+ (WSM 6+) and Nano transponders to fit to the underwater equipment it will be tracking with is new USBLs, including side-scan sonars and transverse gradiometer systems.   

Mini-Ranger 2 is ideal for nearshore operations using small vessels, moored barges and unmanned surface vessels and needing survey-grade positioning performance. It can simultaneously track 10 targets at very fast update rates, is quick to install and has an operating range of up to 4,000 meters. For this application, the Mini-Ranger 2 HPT 3000 transceivers will be mounted over-the-side of Fugro’s vessels to provide very shallow, high-elevation tracking, without losing positioning accuracy.   

Ranger 2 is Sonardyne’s highest performing USBL system, capable of simultaneous long range target tracking, dynamic positioning (DP) and subsea communications. It is being supplied to Fugro with an HPT 7000 Gyro USBL, which combines the vessel heading, pitch and roll data that’s critical to USBL system precision, with an acoustic transceiver – in a single housing. 

Using Gyro USBL means that owners can move their Ranger 2 between vessels of opportunity and avoid the need to undertake post-installation performance tests before subsea operations can begin, saving expensive vessel time.   

Char Franey, Sales Manager for Sonardyne in Houston, says, “Ranger 2 is a great fit for Fugro’s busy work program off the US East coast this summer. Investing in both Mini and standard Ranger gives them the flexibility to mobilize different size vessels for different tasks and have them working close to each other without causing interference. And because all versions of Ranger 2 use the same software, their crews will be able to easily switch between using the two systems.”
