The joint venture Ferrovial Construction and BEMO Tunnelling (Ferrovial BEMO JV) have secured the contract for National Grid involving the construction of a new 2.2km long high voltage (400kv) cable tunnel from Grain to Tilbury and including two 35m deep shafts (15m and 12m diameter respectively), headhouses and Cable Sealing End (CSE) compounds. The Grain to Tilbury project is a proposed electricity infrastructure upgrade, involving the replacement of the existing 1960s Thames Cable Tunnel beneath the Thames between Tilbury and Gravesend. The existing tunnel was built in 1969 and houses 400 kilovolt (kV) transmission cables as part of National Grid's high voltage transmission network. The existing tunnel is reaching the end of its useful life. Visit https://www.ferrovial.com/en/. 06/25
