Integrated REAV-60 USV and Syncro ROV system aims to deliver lower-emission, cost-efficient shallow-water subsea surveys
Leading innovator in Uncrewed Surface Vessel (USV) technology HydroSurv and Norwegian subsea technology and operations company BeyonC have finalised an agreement to deliver a REAV-60 USV configured for the deployment and operation of BeyonC’s advanced Syncro pipeline survey ROV. The collaboration represents a significant step toward a scalable, low-emission operating model for shallow-water subsea survey operations.
The integrated USV-ROV system is designed to address one of the industry’s growing challenges: how to survey expanding subsea cable and pipeline infrastructure more frequently, more efficiently and with less reliance on conventional crewed vessels. By combining HydroSurv’s commercial-duty uncrewed surface platform with BeyonC’s purpose-built Syncro ROV, the companies aim to deliver high-quality subsea data while reducing cost, emissions and offshore personnel exposure.
BeyonC AS, a Norwegian subsea technology and ROV specialist, has developed Syncro specifically for safe, repeatable and high-efficiency survey operations in shallow-water environments. Together, the companies have developed a bespoke Launch & Recovery System (LARS) to integrate Syncro into the REAV-60 surface platform. The agreement was finalised during Oceanology International 2026 in London, following completion of the initial design engineering.
Configured as a dedicated uncrewed host platform, HydroSurv has integrated a tether management winch and a system architecture that enables coordinated positioning between the USV and the ROV. The 2026 updates to the REAV-60 are designed to support precision station-keeping, automated ROV following and real-time connectivity between Syncro and the remote operating team, enabling controlled, repeatable and high-resolution pipeline and subsea cable surveys.
For BeyonC, the collaboration forms part of a clear commercial strategy to industrialise shallow-water subsea survey. The company estimates that the addressable market for recurring pipeline and subsea cable survey represents a NOK 5 billion opportunity, with an estimated need for approximately 70 operational Syncro systems to provide sufficient survey capacity across existing and expanding infrastructure.
By removing the need for conventional crewed support vessels in many shallow-water scenarios, the integrated robotic survey solution has the potential to reduce vessel day rates, cut emissions and make repeat survey of critical infrastructure commercially viable at scale. This is particularly relevant as subsea cable networks and pipeline infrastructure continue to expand, while operators face increasing pressure to document asset integrity, reduce operational risk and lower the carbon intensity of offshore operations.
David Hull, Founder and CEO of HydroSurv, said: “Working in partnership with BeyonC, this project demonstrates what can now be achieved with mid-size USVs in support of inspection-class ROV operations. Syncro has been developed with a clear focus on specific shallow-water inspection requirements, and that clarity translates well into an integrated system. By combining this ROV with a commercial-duty surface platform, we’re able to deliver the stability, control and repeatability needed for reliable deployment without reliance on conventional vessels. It’s a practical example of how uncrewed systems are starting to take on defined operational roles within subsea inspection.”
Morten Hegdal, CEO of BeyonC AS commented: “Subsea survey is entering a new phase. Capacity, cost and emissions now matter just as much as technical capability. We believe the market needs a more scalable way to survey shallow-water cables and pipelines, and Syncro has been developed for exactly that purpose. Integrating Syncro with HydroSurv’s REAV-60 gives us a platform that can move ROV-based survey beyond conventional vessel operations and towards a repeatable, lower-risk and commercially scalable model. For BeyonC, this is an important step in building the survey capacity we believe the industry will need in the years ahead.”
Building upon BeyonC’s early trials positioning the ROV with a small USV, the introduction of launch and recovery capability takes Syncro from remote positioning towards a complete uncrewed survey concept. The preliminary design phase began in December 2025, and construction of the REAV-60 has commenced, with the hulls expected to be completed in May 2026.
The collaboration reflects a shared ambition to accelerate the transition towards safer, more efficient and more sustainable subsea survey operations. As demand for repeat survey of cables and pipelines increases, HydroSurv and BeyonC aim to demonstrate how integrated surface and subsea robotic systems can deliver commercial survey services at scale.
