NjordIC said it has secured a contract to provide full-scope unexploded ordnance (UXO) consultancy services for the Doordewind 1 and 2 grid connection system to be commissioned by Dutch transmission system operator TenneT.
The work will cover survey preparation, offshore survey operations and geophysical data analysis along an export cable route of around 112 kilometres offshore, as well as a further 14 kilometres through the Wadden Sea, the company said.
Under the contract, NjordIC will act as an independent UXO consultant and CS-OOO A-scope holder for TenneT. Its role includes overseeing surveys across beach, tidal, nearshore and offshore areas and delivering all documentation in line with CS-OOO requirements.
The scope of work also includes the processing and interpretation of raw magnetometry data and the production of master target lists to support safe installation of the export cables.
NjordIC said its recently established remote data centre will be used to handle high volumes of survey data, helping to reduce false positives and meet project deadlines ahead of Dec. 31, 2026.
“Doordewind 1&2 is a major project within the Dutch offshore grid programme,” said Erik Wildeman, co-owner and UXO consultant at NjordIC. “We are proud to contribute our specific UXO expertise to the safe, controlled, and efficient delivery of this critical infrastructure.”
The Doordewind projects form part of the Netherlands’ wider offshore grid expansion to support the integration of large-scale offshore wind capacity into the national electricity system, TenneT has said.
