A 30% chunk of the deal is contingent upon TNEI's senior management staying with the company.

UK-based TNEI is a specialist consultancy for the renewables sector and has about 50 staff in Newcastle and Manchester.

Managing director Martin Barnes says: “As part of the Petrofac group, we see great potential both to provide broader services to TNEI’s customers and to help Petrofac build a strong, technically-competent service to the wind renewables sector.
