The Fifth Gas Transmission Pipeline Project (Phase I, II and III) is a gas pipeline in Thailand.

Location

The proposed pipeline would run from Rayong, Thailand to Sai Noi, Nonthaburi, while passing through Chonburi, Chachoengsao, Prachinburi, Bangkok, Pathumthani, and Pra Nokorn Sri Ayudhaya. The exact route appears on p.14 of a September 2016 TRC Corporate presentation on the project.

Background

The pipeline project is expected to cost 99 billion baht ($2.8 billion) and is expected to be completed in 2021. Rayong is the receiving port for Thailand’s LNG imports and is located adjacent to the country’s only re-gasification plant.

Phase-I of the project included 150 kilometers long pipeline and supporting facilities, and was reportedly completed in March 2020. Phase II includes 200 kilometers long pipeline from the tie-in point at Phanomsarakarm district of Chachoengsao to the existing gas pipeline network at Sai Noi Nonthaburi. In 2018 PTT signed a contract with JSC OGCC KazStroyService (KSS) for construction of Phase II. As per PTT's Annual Report 2021, the pipeline segments till the control station 5.8 in Chachoengsao had been commissioned.

The pipeline was commissioned in May 2024.
