ARCHIE Bethel, one of Scotland’s leading engineering executives, is set to take charge of sector heavyweight Babcock International. The London-based group said Mr Bethel will succeed Peter Rogers as chief executive on 31 August. Mr Bethel has led Babcock's marine business, at Rosyth in Fife, since 2004. He has been a main board director since 2010. Babcock said Mr Bethel had overseen the successful growth of the division from a £273 million business in 2004 to a £1.6 billion business, whilst reinforcing its reputation of being trusted to deliver increasingly complex engineering programmes. Mr Bethel started his career as an engineer in the oil and gas industry and went on to hold senior roles in the sector before becoming chief executive of Scottish Enterprise Lanarkshire. Prior to joining Babcock he was chief operating officer at Motherwell Bridge. Mr Rogers will retire on 31 August following 13 years in post.
