The company bought qedi from its owner-managers for £33m and paid £29m at closing, with the balance to be paid over the next two years.

Amec chief operating officer Neil Bruce said that this acquisition strengthens Amec’s project delivery capability across its key sectors and supports the Vision 2015 strategy.

"Our capability, geographic coverage and customer relationships, combined with qedi’s specialist technology and expertise, provide us with the ability to deliver integrity across the whole life-cycle of a project for our customers," Bruce said.

Headquartered in Aberdeen, qedi provides ‘technical integrity’ project delivery services to international oil companies in the UK, Gulf of Mexico, Middle East, the Caspian and Australia.
