Sembcorp Industries has hired Contact Energy's chief financial officer to take on the same role in its organisation.
Mr Graham Cockroft will take up the position on Sept 3, the rig builder announced yesterday before the stock market opened.
He will replace Mr Koh Chiap Khiong, who is now heading the group's utilities business in Singapore, South-east Asia and China.
Mr Koh has also been named Sembcorp's chief transformation officer.
Mr Cockroft has been Contact Energy's chief financial officer for the past six years, a job he took up after being the New Zealand integrated energy company's chief operating officer.
He also spent almost two decades at BG Group in various senior strategy, business development and operational roles, primarily in Britain and South America, Sembcorp said.
Sembcorp chief executive Neil McGregor said Mr Cockroft was picked after an extensive global search.
"I am confident that Graham will be a great asset to our senior management team, with his strong international experience, finance background and deep understanding of global gas, renewables and merchant and retail power markets," Mr McGregor said.
He also expressed appreciation for Mr Koh's work as chief financial officer over the past eight years.
"With our business facing a dynamic environment with changes in regulatory environment, market demands and fuel mix, Chiap Khiong has now stepped up to the challenge of leading our key utilities markets of Singapore, South-east Asia and China to deliver performance and growth," Mr McGregor said.
"As chief transformation officer, he is also overseeing our efforts to strengthen our organisation and capabilities to support our strategy."
