Former Atkins chief executive Keith Clarke is the latest high-profile appointment to the firm set to build the world’s first tidal lagoon power plant in spring 2015.
Mr Clarke has been named as non-executive chairman of Tidal Lagoon Swansea Bay plc.
Former chief executive of Laing O’Rourke Australia Steve Hollingshead joined the £850m project as construction director in June.
Mr Clarke was formerly executive vice-president of Skanska AB as well as chief executive of Trafalgar House Construction and then Kvaerner Construction.
He was chief executive at Atkins for eight years until 2011, when he handed over to Uwe Krueger.
He said: “This is an extremely exciting project whose time has come. It will set the standard for a new kind of energy infrastructure and has truly global implications.
“It is the right project at the right time for me and I am relishing the prospect of getting back into major project delivery and building a best-in-class team.”
Tidal Lagoon Swansea Bay chief executive Mark Shorrock said: “We want the Swansea Bay Tidal Lagoon to establish a blueprint for a series of tidal lagoons that allow the UK to harness its incredible range resource.
“Keith understands the challenges of building large infrastructure and the climate imperative to do so in a low-carbon manner. And he has grown exceptional teams to achieve exceptional results. He’ll be a huge asset for us.”
