Fugro Deploys Uncrewed Vessel for Viking Link Survey
The 18-meter Blue Eclipse vessel is conducting an environmental survey along the 765-kilometer subsea interconnector.
Updated on Oct. 27, 2026 in Utilities
Fugro is using an uncrewed surface vessel to survey the Viking Link, an undersea electricity interconnector capable of transmitting 1.4 GW of power. The mission involves assessing 193 specific transects along the route, which spans from the UK to Denmark.
Why it matters
The survey monitors the physical condition of the interconnector, which is vital for maintaining the stability of the high-capacity link between the Bicker Fen and Revsing substations. Ensuring the integrity of this infrastructure supports reliable cross-border energy transmission.
The Viking Link provides a 1.4 GW capacity connection between UK and Danish electrical grids. The survey is capturing data across 193 distinct transects, each measuring 100 meters in length.
The players
Fugro
Fugro is a global geo-data specialist that provides site characterization and asset integrity solutions for the energy and infrastructure sectors.
The details
Controlled from a remote operations center in Aberdeen, the 18-meter Blue Eclipse vessel executes the survey across the North Sea. The operations cover a distance from the UK nearshore at Mablethorpe to the offshore limit near the UK/Netherlands border.
Timeline
The Viking Link interconnector was officially inaugurated in April 2024.
A formal Notice to Mariners for the survey was issued on October 8, 2026.
Survey operations began on October 22, 2026.
The survey is scheduled to conclude on November 10, 2026.
Market Landscape
This activity follows the established maintenance cycle of the Viking Link interconnector. It demonstrates the utility industry's shift toward remote, automated asset monitoring to reduce human risk and operating costs on critical cross-border energy infrastructure.
The survey ensures the continued reliability of the 1.4 GW electrical link that helps stabilize energy supply across European markets. Regular inspections like these are essential to preventing long-term service outages that could impact electricity pricing for end users.
The takeaway
The deployment of autonomous vessels for deep-sea infrastructure inspection represents a broader industry pivot toward increased operational efficiency. By leveraging remote operations centers, companies can perform critical maintenance tasks more frequently and with higher safety margins.
