Energy and marine consultancy ABL has been appointed as marine warranty surveyor to support transportation and installation (T&I) operations for the construction of the Centre Manche 1 and Centre Manche 2 offshore grid connection in Normandy, France.
Centre Manche 1 and Centre Manche 2 are part of two offshore wind projects – Appel d’Offre 4 (AO4) and Appel d’Offre 8 (AO8).
They aim to contribute towards the French government’s ambition of allocating 1GW of offshore wind energy per year, from 2023 onwards.
Centre Manche 1 will connect the AO4 (1050MW) offshore wind farm and part of AO8 (200MW) to the 400 kV substation at Menuel through a 100 km long DC export cable.
Centre Manche 2 will connect the A08 offshore wind farm to the 400 kV substation at Tourbe via a 105 km long DC cable.
Both offshore substations will each have a capacity of 1.25GW.
ABL’s operations in France will act as marine warranty surveyor (MWS) for the transportation and installation campaign for the Centre Manche 1 and 2 offshore substations, the 100 km long DC export cable, and the three 2 km long interstation links.
The platforms will be sister topsides, with an estimated weight of 13,300 tonnes each, while the jackets will weigh approximately 7,000 tonnes each.
ABL’s scope of work will cover the technical review and approval of all T&I engineering documentation pertaining to warranted activities, participation to HAZID/HAZOP meetings, suitability surveys of the installation vessels, onshore and offshore attendances to approve the marine operations, and issue of certificates of approval.
Hugues Delanoue (pictured: left), regional managing director for ABL in Europe and West Africa, said: “Being selected for this project reflects our technical reputation in the French market, particularly for T&I work for France’s offshore wind projects, including bottom-fixed platforms and subsea cables.
“Further to this, our in-house team of marine and engineering consultants draw upon experience from more than 330 offshore wind projects globally.”
The company’s work will begin in the third quarter of 2024 and continue until project delivery in 2032.
