David Walker has been appointed as chief executive officer of DNV Kema.

Walker, who will replace Thijs Aarten, who has decided to pursue opportunities as an independent advisor in the global energy transition, joins from the position of chief strategy officer for the DNV Group.

Walker has more than 30 years of international experience covering the entire energy value chain. He started his career as a geologist for Amoco, before moving into operations and then major capital project management, the latter for BHP Billiton.

He joined DNV in 2007 to further develop its energy business, which at that time consisted of clean energy as well as oil and gas. He then moved into the role of chief strategy officer within the DNV Group, where he played an integral role in the acquisition of the majority shareholding of KEMA.

“DNV KEMA has an important role to play in the future of energy – helping our customers build environmentally and economically sustainable businesses in today’s tough economic and risk realities,” said Walker. “I look forward to working alongside the 2,300 competent, innovative and committed people of DNV KEMA to make this happen.”

At the same time, Aad van den Bos will be appointed chief financial officer.

Both Walker and Van den Bos will be based in DNV KEMA’s headquarters in Arnhem, the Netherlands.
