The three cryogenic tanks have a total capacity of 570,000m3 and form part of a larger project for an LNG storage and regasification terminal. Bouygues Travaux Publics will be responsible for constructing the external walls of the tanks in post-tensioned concrete, as well as their foundations. Each tank will be 91m in diameter and 50m tall, making them among the largest ever built.
Use of an on-site ready-mix concrete plant will reduce noise and traffic caused by concrete trucks.
The contract was signed with Dunkerque LNG, a subsidiary of EDF. Work will begin early next year and will last three and a half years. Some 350 people will be involved in peak periods, 100 of them hired locally.
The major project marks the return of Bouygues Travaux Publics to the LNG cryogenic tank market. Previous projects include tanks in Ras-Laffan, Qatar, in 1996 and Damiette, Egypt, in 2004.
