Jan De Nul to Carry Out 'Industry's First' Simultaneous Multi-Cable Installation for TenneT

By MGN EditorialMarch 14, 2026 at 12:06 PM

Belgian offshore contractor Jan De Nul plans to install three subsea power cables simultaneously, a first-of-its-kind project for the offshore energy sector.

In a significant development for the offshore energy industry, Belgian contractor Jan De Nul has announced plans to carry out the 'industry's first' simultaneous multi-cable installation project for TenneT, the Dutch-German transmission system operator. According to an article published by Offshore Energy, Jan De Nul will install three subsea power cables as part of TenneT's offshore grid expansion plans in the North Sea. This innovative approach marks a departure from the traditional practice of installing cables sequentially, which can be time-consuming and resource-intensive. 'By installing the cables simultaneously, we can significantly reduce the overall project duration and increase efficiency,' said a spokesperson for Jan De Nul. 'This is a game-changing development that showcases our commitment to driving innovation in the offshore energy sector.' The project is expected to commence in the coming months, with Jan De Nul utilizing its specialized cable-laying vessels and advanced installation techniques to execute the simultaneous multi-cable installation. This approach is expected to set a new benchmark for the industry and pave the way for more efficient and cost-effective offshore grid development in the future. 'TenneT's grid expansion is crucial for the continued growth of offshore wind power in the North Sea,' said the Offshore Energy article. 'Jan De Nul's innovative solution will help accelerate this process and support the region's transition to renewable energy.' The successful completion of this project could have far-reaching implications for the offshore energy industry, potentially inspiring other contractors to explore similar approaches to cable installation and grid development. As the global demand for renewable energy continues to rise, innovative solutions like this will be essential for meeting the industry's evolving needs.
