Hybrid AUV Completes Depth of Burial Survey for Offshore Wind Farm
Bay in water depths ranging between 12m and 28m. The WTG’s are connected by 161 inter array cables which total circa 147km in length. The worksite is known for high subsea currents, so any solution had to cope with current up to 2kts.Modus mobilized its HAUV-2 system, equipped with Optimal Ranging Orion Cable Tracking System and dual head R2Sonic 2024 Multibeam Echosounder, on the chartered DP2 vessel “Noordhoek Pathfinder”. The inherent power and stability of HAUV-2 provides unrivalled high current workability and the system operated throughout the local tidal cycle
ORION Boosts STR’s Portfolio
Subsea Technology and Rentals (STR) added Optimal Ranging’s ORION pipe and cable tracker systems to its selection of underwater detection systems. ORION is Optimal Ranging’s new flagship product for Underwater Utility surveying. Extending LIBRA’s Fieldsens technology ORION now includes MultiSens and is available at STR in two, four and six sensor configurations. ORION is rated to a depth of 2,000m, suitable for near-shore and deep-sea ROV survey and mountable on other platforms such as a sled or wing. ORION is compatible with leading hydrographic survey
MMT Performs Cable Survey for Statnett
; MMT conducted the cable inspection and position survey by M/V Stril Explorer using the Work Class ROV Kystdesign Supporter. In Rombaken it was a challenging survey for the ROV with almost vertical slopes on both ends of the fjord. The cable tracking system used was the ORION system by Optimal Ranging. It was the first time MMT used the system on HVAC cables and the system showed good positioning horizontally and promising results vertically. ”We work together with Optimal Ranging on developing functionality to track multiple cables simultaneously for future projects
