Fugro has completed a six-month seabed survey of the route for the 1.4GW Viking link, which will connect the UK and Danish electricity systems.
The work started in March last year in Danish waters, and crossed the southern North Sea through German and Dutch territorial waters, before ending in the UK.
Fugro collected water depth and sediment data using a multibeam echosounder, a side scan sonar, magnetometer, pinger and sparker over the full corridor length of the link.
Offshore and nearshore geotechnical surveys included vibrocore and cone penetration testing, as well as benthic investigations.
The company also used a remotely operated vehicle to identify and locate subsea assets, such as cables and pipelines that cross the proposed Viking route, and measure the burial depth of the assets.
Viking is a joint venture between the UK’s National Grid and Denmark’s Energinet.
Work on the 630km link, which would connect Revsing in Denmark to Bicker Fenn in the UK, is scheduled to start in 2018 and be complete in 2022.
