Helix Energy to Work on Ørsted’s Hornsea 3 Offshore Wind Farm
Helix Energy’s marine contracting business unit, Helix Robotics Solutions, has secured a contract from Seaway7, the renewables unit of Subsea7, to bury inter-array cables at Ørsted’s Hornsea 3 offshore wind farm in the UK.
The project, managed from Helix’s Aberdeen offices, involves burying all 192 inter-array cables spanning approximately 500 km in total.
The company intends to deploy the construction support vessel Grand Canyon III equipped with the T1500 jet trencher, the i-Trencher trenching system, a work-class remotely operated vehicle, and related survey services.
The contract duration is estimated to exceed 300 days and is set to commence in the third quarter of 2026. While the contract value remains undisclosed, Scotty Sparks, Helix’s executive vice president and chief operating officer, described it as one of the company’s largest trenching agreements.
The Hornsea 3 wind farm, positioned 160 km off the Yorkshire coast, boasts a capacity of 2.9 GW, making it the largest individual offshore wind farm to date. It will elevate the total capacity of the Hornsea offshore wind zone to 5.4 GW.
