About 56% of revenue will be in oil and gas, with nearly 20% in clean-energy work, says Simon Naylor, group president for the Americas. The Houston-based group will account for 42% of corporate employees and 47% of overall revenue. Naylor was in the same role for Amec since 2012; Amec CEO Samir Brikho assumes that role for the larger corporation. Foster Wheeler CEO Kent Masters leaves the firm but stays a non-executive director.
