PTT Pcl, Thailand’s largest oil and gas company, said it had chosen Chansin Treenuchgron as next CEO in place of Tevin Vongvanich, who will retire later this year.

Chansin, 57, will take up the company’s helm on Aug. 31 after Tevin reaches the compulsory retirement age of 60. Chansin will have a term of 20 months, PTT said in a statement.

Thai state-owned enterprise law requires employees retire at the age of 60.

Chansin, who joined PTT in 1982, is currently the company’s ​chief technology and engineering officer. He also served as senior executive vice president for company’s petrochemicals and refining business unit.

PTT Chairman Piyasvasti Amranand said the board unanimously voted for Chansin’s appointment.

Chansin’s expertise in technology is in line with the company’s plan of using disruptive technologies to seek new businesses, Piyasvasti said in a statement.
