THAILAND has completed the first phase of its $1-billion, third gas transmission line, and the pipeline has begun commercial operations. The project, which comprises 424km of 42-in line offshore and 5km of 42-in and 110km of 36-in line onshore, will deliver 250m cuft/d of gas from Chevron Exploration & Production’s Erawan gasfield in the Gulf of Thailand to Bang Pakong, east of Bangkok.
The deliveries augment gas transmitted from the gulf fields through PTT's two 20-year-old transmission lines that are operating at their capacity limits of 1,800m cuft/d, officials of the state-controlled PTT said.
Construction of the second section of the new transmission line – 334.5km of 42-in pipeline – is 6-9 months behind schedule and will be completed in first quarter of 2008.
It will connect the Erawan field with the Arthit gasfield, and extend into Block A-18 of the Malaysia-Thailand Joint Development Area in the southern part of the gulf. Completion of this second stage will raise gas throughput volume in the third pipeline by 500m cuft/d to its maximum capacity of 750m cuft/d.
PTT also plans to install a gas-compression facility at the Erawan field to raise the third gas line's total throughput capacity to 1,900m cuft/d in 2010, when additional supplies from fields in the southern gulf become available.
