Thierry Pilenko has decided to retire as executive chairman of energy service giant TechnipFMC.
Chief executive Doug Pferdehirt will assume the role of chairman, effective May 1.
Mr Pilenko was appointed executive chairman in January 2017 to support the integration process following the merger between French firm Technip and US business FMC Technologies.

Mr Pilenko said: “It has been an honor and a privilege to lead the women and men of Technip during 10 years and to support the integration of Technip and FMC Technologies over the last 2 years.
“TechnipFMC is today a true leader in the oil and gas business and I am fully convinced that under Doug’s leadership, it has the skills, technologies, assets, and talents to continue driving the change our industry needs.
“I thank you all for your team spirit, dedication, and hard work which made the past 12 years the most amazing journey of my career.”
