Deep will use hydrographic and geophysical techniques to determine the level of seabed cover above the cables and identify objects and seabed features that could pose a risk to their integrity. Where required, selected findings will also be visually inspected to provide additional information for assessment.
The resulting data will provide an accurate and up-to-date picture of the condition of their offshore cable infrastructure, supporting TenneT’s ongoing monitoring and maintenance activities, early identification of potential issues, and continued compliance with applicable permit requirements.
Maarten Abbenhuis, COO of TenneT, said, “As we continue to connect more offshore wind farms to the high-voltage grid and install more interconnection cables between countries, offshore transmission plays an increasingly important role in the energy infrastructure. Regular monitoring is essential. Periodic surveys allow TenneT to assess conditions along its cable routes, monitor changes over time and identify potential risks, all to prevent outages. The monitoring services of Deep will play an important role to maintain the high reliability standards of the offshore grid infrastructure.”
“We are proud to contribute to the safe and reliable operation of TenneT’s offshore grid,” says William Waggeveld, Commercial Director at Deep. “Regular monitoring is an essential part of managing subsea infrastructure, and this project allows us to put our survey expertise to work on assets that are critical to the Dutch renewable energy system.”
The project forms part of Deep’s activities in offshore hydrography and geophysics, supporting the inspection, maintenance, and management of critical marine infrastructure in the renewable sector.
