Golar LNG has named a successor to outgoing finance chief and long-time figure Graham Robjohns.

Callum Mitchell-Thomson, a 21-year veteran of JP Morgan, will take over the role 20 April with Robjohns staying on until the end of the month.

"On behalf of the Board and staff at Golar LNG we thank Graham for his long and valuable service to the company and wish him well in his future endeavours," said Golar LNG chief executive Iain Ross.

"We welcome Callum into Golar and look forward to benefitting from his broad Finance and Banking background as the company moves forward."

The New York-listed gas carrier owner said Mitchell-Thomson had spent his carrer at JP Morgan advising companies in energy, utilities and infrastructure on mergers and acquisitions and capital markets transactions. He served as co-head of energy, utility and infrastructure investment banking in Europe, the Middle East and Africa for a decade and was the head of corporate finance there for three years.

He holds both bachelors and masters degrees from the London School of Economics.

Robjohns had been with Golar LNG for 20 years.

"I feel the time is now right for a change and for me to seek new challenges outside Golar," Robjohns said in announcing his departure last October. "I wish the company well and look forward to seeing it flourish."

During the announcement, Robjohns was said to be focusing on "structural opportunities" for Golar Partners.

Then, Golar LNG was nearing a spin-off for its LNG shipping fleet and was expected to be completed by the end of 2019.

Instead, the deal fell apart in late November.

In February, Ross said "good progress" was being made on the spin-off efforts.

In late trading Tuesday, Golar LNG shares were up $2.57, or 31.06%, to $10.86.
