Dutch owner Vroon has clinched a three-year charter extension for an anchor-handler in Thailand.
The 65-bp VOS Ares (built 2012) has been kept on by PTTEP, it said.
This commits the ship until at least June 2022.
The unit operates as a production-support vessel, forming part of PTTEP's core fleet.
It has "performed well for PTTEP in the Bongkot field since October 2018," Vroon said.
