Fugro has completed the seabed survey for the Viking Link. The Viking Link, a joint venture between the UK’s National Grid and Denmark’s Energinet, is a proposed 1,400MW high voltage direct current electricity link, which passes under the North Sea, from Revsing in Denmark, to Bicker Fenn in the UK. The interconnector will enable more effective use of renewable energy, access to sustainable electricity generation and improved security of electricity supplies.
Water depth and sediment data were collected using multibeam echosounder, side scan sonar, magnetometer, pinger and sparker over the full corridor length of the link. Offshore and nearshore geotechnical investigations included vibrocore and cone penetration testing. A remotely operated vehicle (ROV) was deployed to identify and locate subsea assets, such as cables and pipelines that cross the proposed Viking Link route, and measure the burial depth of the assets. The ROV also recorded video and multibeam echosounder data. To identify the ecological environment, Fugro carried out benthic investigations including grab samples and photography. Construction on the Viking Link project is planned to start in 2018 and is planned to be operational by 2022.
