General – Risk Assessment
Intertek announced the delivery of a comprehensive risk assessment for five offshore wind export cables in the North Sea and the Baltic on behalf of Danish transmission system operator Energinet.
These cables will connect offshore wind energy from the North Sea I, Kattegat, and Kriegers Flak II wind farms to the Danish mainland, reinforcing Denmark’s commitment to sustainable energy.
Intertek Metoc conducted an initial assessment of analysis of threats and assessed the related risks to the integrity of the subsea cables’ lifetime operation. Utilising bathymetric, geophysical and geotechnical route survey data provided by the client, along with vessel and fishing data, Intertek’s experts evaluated potential threats and their impacts along the cable routes.
The Cable Burial Risk Assessment also included recommendations for sufficient burial depths to mitigate identified risks, such as interaction with fishing gear or ship anchors, ensuring the long-term reliability and safety of the subsea cables.
As part of the work scope, Intertek Metoc provided a high-level Burial Assessment Study (BAS). This study evaluated various cable installation methods to determine the most effective approach for ensuring the cables’ protection and performance.
The BAS considered factors such as seabed conditions to determine the installation efficiency of various subsea power cable tools, providing a high-level strategy for cable installation.
