New research highlights the need for an integrated approach to offshore data cables
The deployment of offshore data cables requires stronger coordination and closer alignment with energy infrastructure projects in the North Sea. This is the key conclusion of the report Data Cables: From Spatial Pressure to Strategic Coordination, conducted by Arcadis and Pondera on behalf of the Sea Cable Coalition.
Data cables are critical to the Netherlands
International data cables form the backbone of the digital economy. They connect the Netherlands to the rest of the world and support economic growth, innovation, scientific research, information security and strategic autonomy. At the same time, Dutch demand for data traffic is growing by approximately 35% annually. Without further expansion of digital infrastructure, the Netherlands risks losing its position as Europe’s leading digital gateway.
Opportunities for better coordination
The North Sea and coastal zone are becoming increasingly crowded. While energy infrastructure is already supported by a national strategy with clear planning and coordination, data cable development remains largely market-driven. The study shows that closer coordination between energy and data cable projects could improve the use of scarce space, reduce costs and accelerate permitting procedures.
According to the researchers, reusing existing infrastructure, cable corridors, survey data and permitting processes could contribute to a more efficient rollout of new connections. At the same time, limited coordination between energy and data infrastructure projects remains a significant challenge. Current plans for offshore energy infrastructure are already largely fixed, making short-term integration difficult.
The greatest opportunities for collaboration lie in the coastal zone and at cable landing points. Here, spatial planning, surveys, permitting procedures and construction activities could potentially be coordinated and organised jointly.
From spatial pressure to strategic coordination
To unlock these opportunities, Arcadis and Pondera propose a two-track approach.
The first track focuses on policy integration, central coordination and clear ownership, ensuring that digital infrastructure receives a full and equal place in spatial, economic and strategic decision-making.
The second track consists of pilot projects and practical quick wins that can provide valuable experience with the combined deployment of energy and data cable infrastructure.
For the Sea Cable Coalition, the report underlines the importance of a national vision for international data cable connectivity. Only through timely coordination and an integrated approach can the Netherlands maintain and strengthen its position as a leading digital hub.
