From as early as 2003, Tractebel has been supporting the Autoridad del Canal de Panama (ACP) with the expansion of the Panama Canal to accommodate Post Panamax vessels, which are 48.5 m wide and 386 m long. Tractebel was the technical leader of the Consorcio Post-Panamax (CPP) which grouped the different partners who participated to this project. The expanded Panama Canal was inaugurated in June 2016.
