RNE provides project management, engineering and design services including process, mechanical, piping, civil and structural engineering for oil, gas and petrochemical process plants.
Kentz said it will pay the purchase price of £10m over the next four years.
Kentz Group CEO Hugh O’Donnell said that RNE has built an impressive market presence in the oil, gas, petrochemicals, metals and mining market sectors in South Africa.
"By bringing the experience of RNE together with Kentz’s presence in a broader number of sectors we are now well positioned to offer an expanded range of niche EPC solutions to a wider client base throughout Southern Africa," O’Donnell said.
