Arcadis

Arcadis Nederland BV was awarded a marine consultancy contract by Belgium's transmission system operator Elia together with Denmark's Energinet for the offshore route development of the TritonLink hybrid HVDC interconnector. The scope covers the section from the Danish energy island, through the Modular Offshore Grid 2 (MOG 2 / Princess Elisabeth Island) in Belgian waters, including the route to the Belgian shore and landfall in Belgium; the cable connections from the Danish energy island to the Danish onshore landfall are excluded from this package. Arcadis's mandate spans route development, permit planning, and support throughout consultation activities up to the project's final investment decision (FID), as well as support during route survey and sampling-campaign preparation and implementation. The award positions Arcadis as the long-running marine-consenting and route-engineering advisor for the Belgian-led leg of the project, which has the longer offshore route (approximately 773 km BE-island compared with around 140 km island-DK). The contract was announced on 1 August 2023, when TritonLink was being targeted for commissioning in the early 2030s. The commissioning horizon has subsequently slipped to 2036 at the earliest following an August 2024 statement from Danish Climate and Energy Minister Lars Aegaard, and to a further uncertain horizon following Elia's June 2025 decision to drop the original HVDC contract for Princess Elisabeth Island and develop an "alternative concept" for the next phase of the Belgian offshore energy hub.
