Singapore-based Federal said Gunanusa had been given the go-ahead by PTTEP to proceed with Lots 1 and 2 of the offshore development valued at about US$305 million.

Lot 2 - which was confirmed on 7 October - comprises two wellhead platforms, associated pipelines and tie-ins. The value of Lot 2 is about US$150 million, said Federal.

Work on Lots 1 and 2 will be carried out concurrently, and the completion date is in the second quarter of 2018, added Federal, which said it also supports Gunanusa in terms of procurement, management and other ancillary support services for Zawtika.
