Wind Energy – Inter Array Cables
Inter-array cable installation is now in full progress at the East Anglia Three offshore wind farm, marking another significant milestone in the delivery of one of the UK’s largest renewable energy projects.
The cable-laying vessel (CLV) Seaway Aimery commenced installation works in January, deploying inter-array cables that will connect the wind turbines to the offshore converter platform. The operation is currently supported by the vessel Seaway Moxie, with two additional vessels scheduled to join the campaign around 27 February to further accelerate progress.
The walk-to-work (W2W) vessel Windea Clausius, alongside Seaway Moxie, will deploy specialist personnel and equipment to the wind turbines and offshore substations via a motion-compensated gangway system.
Meanwhile, Grand Canyon 3 will undertake inter-array cable trenching and burial operations to ensure long-term protection and reliability of the subsea infrastructure.
Prior to mobilizing for East Anglia Three, Seaway Aimery was engaged in cable installation activities at the Revolution Wind offshore wind project in the United States.
The vessel departed the U.S. for Europe in December 2025 to support the UK development.
Located approximately 69 kilometers off the coast of Suffolk, offshore construction at East Anglia Three began in April 2025 with the installation of the first of 95 monopile foundations.
The 1.4 GW wind farm will feature 95 Siemens Gamesa 14+ MW turbines and is scheduled to achieve initial operations in the fourth quarter of 2026.
Once operational, East Anglia Three will play a pivotal role in strengthening the UK’s renewable energy capacity and advancing the country’s transition to a low-carbon energy system.
