HydroSurv has announced the sale and delivery of its latest REAV-25 uncrewed surface vessel (USV) to Skanska Norway AS, marking a significant milestone in Skanska’s expansion of uncrewed survey capability for infrastructure projects across the country.

Skanska is a leading civil engineering and construction company with a substantial portfolio of works spanning inland waterways, ports and harbors, and coastal environments. Supporting the successful delivery of these projects is Skanska’s in-house survey and inspection unit, where the REAV-25 will play a key role in strengthening inland hydrographic survey operations.

The USV will be primarily deployed to deliver high-resolution bathymetric surveys using a Norbit iWBMS multibeam echo sounder, supporting the design, construction and long-term maintenance of infrastructure located over, under and alongside the water. The acquisition reflects Skanska’s growing adoption of uncrewed technologies to improve data availability, operational efficiency and safety, while reducing the environmental footprint of survey activities.

Designed for zero-emission day operations, the REAV-25 is a sheltered-water, multipurpose USV capable of supporting a wide range of hydrographic and environmental data collection campaigns. The vessel is equipped with twin 2.5 kW rim-driven thrusters, minimizing the risk of entanglement or damage during shallow-water operations, and is powered by a 6-kWh lithium battery system enabling full-day endurance. As a commercial-grade platform, the REAV-25 features HydroSurv’s Virtual Watchkeeper Vessel Control System (VCS) alongside the Dynautics Spectre autopilot.

David Hull, Founder and CEO of HydroSurv, said: “We’re extremely proud to have been selected by Skanska to support the delivery of this new REAV-25 USV for survey operations in Norway. The portability and flexibility of the platform allows rapid mobilization and the repeatable collection of high-quality survey data, aligning well with Skanska’s operational and project delivery requirements.”

Stuart Duncan, Team Lead (Seabed Mapping & Inspection) at Skanska Survey Norway AS, said: “We contacted several companies and looked at various USV solutions in this now crowded workspace, but HydroSurv really shone as a company that Skanska felt it could do business with. We have been impressed throughout this process and look very much forward to receiving and working with our REAV-25. The compact vehicle is ideal for our current area of growth, and moving personnel from the field to the office will make us far more competitive to our clients.”

The USV, named Saga, will complete trials in the UK in March 2026 and is expected to enter operational service with Skanska in Norway in early spring.
