Equinor chief financial officer Lars Christian Bacher has resigned after almost three decades with the Norwegian state-controlled energy giant.
Bacher will exit the role from 1 November but will remain employed by the company until 31 May next year.
He is being replaced as chief financial officer by Svein Skeie, who is currently senior vice president for chief financial officer performance management and control.
Bacher, who joined the then-Statoil in 1991, said of his impending exit: "After almost 30 years of exciting challenges at Equinor, it is time to look ahead at new opportunities outside the company.
"I am thankful for the interesting roles that the company has given me over the years."
Chief executive Eldar Saetre - who is himself on the way out the door next month after an earlier-disclosed management change that will see Anders Opedal step into the role - said Bacher had "successfully delivered in his important operative leadership roles" at the company.
"As a member of the corporate executive committee for more than eight years, first as the head of the international business, and in the past two years as chief financial officer, he has helped shape and strengthen the company.
"I have greatly appreciated our close collaboration, and wish Lars Christian all the best for the future."
Bacher held various positions at Statoil and Equinor, including offshore installation manager on the Norne and Statfjord fields, as well as senior vice president of Gullfaks operations and the Tampen area.
He oversaw the merger process with Norsk Hydro and was country manager for Statoil in Canada before being named executive vice president for development & production international in 2012.
He was named chief financial officer in August 2018.
Skeie joined Statoil in 1996 and has held several leadership positions within finance, business development and economic analysis.
"With his long-standing experience from the chief financial officer area and other leadership positions in the company, he is highly respected both in and outside Equinor," Saetre said of Skeie.
