Denmark's Orsted said on Tuesday that its finance and operations chiefs were stepping down with immediate effect after the offshore wind farm developer earlier this month reported large financial losses.
The search for successors to Chief Financial Officer (CFO) Daniel Lerup and Chief Operating Officer (COO) Richard Hunter will begin immediately, Orsted added.
"Orsted, along with the rest of the industry, is experiencing a challenging and volatile business environment," CEO Mads Nipper said in a statement.
"The board of directors and I have agreed with our current CFO and COO that we need new and different capabilities," he said.
The offshore wind industry has found itself in a perfect storm of rising inflation, interest rate hikes and delays in the supply chain struggling to cope with growing demand.
Orsted, the world's largest offshore wind developer, on Nov. 1 scrapped two U.S. offshore wind projects, flagging $5.6 billion in related impairments after delays, partly due to vessel availability, meant costs soared.
At the time of canceling the projects, Nipper said the company had invested a significant amount in the most advanced project, Ocean Wind 1, and that this had been the wrong decision.
Rasmus Errboe, who has been with Orsted since 2012 and runs the company's European operation, will serve as interim CFO.
"Together with the finance team and the group executive team, Rasmus Errboe will lead the work on supporting Orsted's capital structure and long-term commitment to its credit rating," the company said.
Board member Andrew Brown, who has executive experience from Shell and Portugal's Galp, was appointed interim COO, Orsted said.
The company's financial guidance and expected level of investment for 2023 is unchanged, it added.
Orsted shares were little changed, up by less than 1%, at 1142 GMT.
Separately on Tuesday, German utility RWE announced an 82% jump in profits for the first nine months of the year on strong performance at its commodity trading business and from its gas-fired power plants.
The company said contracts it had signed for its U.S. offshore wind projects were secured recently and were therefore more reflective of current costs.
