ARC

ARC Marine signed an agreement on 4 December 2025 with the OranjeWind joint venture of RWE and TotalEnergies to supply 66 nature-inclusive Reef cubes for the OranjeWind offshore wind farm (Hollandse Kust West VII) in the Dutch North Sea. The cubes will be deployed around eleven of the project's 53 turbine foundations, creating an estimated 1,440 square metres of new artificial reef habitat in addition to the bulk scour protection provided by the rock placement campaign. Each Reef cube is approximately 1.5 metres tall and weighs about 6,000 kilograms, manufactured from low-carbon recycled materials certified as safe for the marine environment. The cubes incorporate cavities, textures and shell material designed to promote settlement of native species — particularly cod and native oysters — and are intended to remain in place throughout the operational life of the wind farm. The supply forms part of OranjeWind's broader system-integration and biodiversity programme alongside the wider scour protection works being executed by Jan De Nul. The press release does not disclose contract value, delivery schedule, or which specific eleven turbine positions will receive the cubes; deployment timing is aligned with the project's offshore construction phase which began in 2026.
