Three Vinci subsidiaries have secured a £176m contract with National Grid to build a 190,000 cubic metre liquefied natural gas tank. The firms – Entrepose Contracting, Vinci Construction Grands Projets and Taylor Woodrow – will work together on the project to expand the capacity of the largest liquified natural gas terminal in Europe on the Isle of Grain in Kent. National Grid has awarded an engineering, procurement and construction (EPC) contract to the firms, with works due to run until 2025. Vinci said the full containment tank has a 9 per cent nickel steel inner tank with a pre-stressed concrete outer shell, which will be poured in-situ using slipforming. The French-owned contractor has been involved in the construction of around 20 liquified natural gas tanks worldwide over the past 15 years, three of which are still in progress. These include two 160,000 square-metre tanks in Russia and a 225,000 square-metre facility in Canada.
