On 19 June 2008, the cabinet approved the revision of the Master
Plan for Natural gas Transmission Pipeline System Project (Revision 3/B.E.
2544-2554) to be used as a framework for investment of 165,077 million baht in
the 14 projects of constructing Natural gas Transmission Pipeline System. The
Master Plan optimizes the capabilities of PTT Natural Gas Transmission Pipeline,
West and East Sides (including Pipeline from Nam Phong), rising from 3,680
million cubic feet per day (MMcf/d) (at actual heating value) at the end of
2007, to 6,980 MMcf/d (at actual heating value),together with three divided
phases of investment and the further investment in the Offshore Gas Spur Lines
Project
The First Phase of the Project:
- The Project of Compressor Unit Installation at Block valve West 7 (BVW#7) in
Kanchanaburi Province, was conducted to enhance the system’s capability in
receiving and transmitting natural gas from Myanmar up to 1,300 MMcf/d. The
project was complete in July 2006.
- The Project of Natural Gas Transmission Pipeline, Sai Noi-North Bangkok and
South Bangkok Power Plants, was executed to serve the demand of gas utilization
under the Project of the Combined Heat Power Plant, North and South Bangkok , as
well as that of private and transport sectors to reduce environmental pollution
in Bangkok Metropolitan and Vicinity. In response to those projects, PTT planned
to undertake a project to lay the 70-kilometer natural gas transmission
pipeline, 30 inch in diameter, linking the Natural Gas Transmission Pipeline
,Ratchaburi-Wang Noi at Sai Noi District to South Bangkok Power plant.
Meanwhile, the 10 km natural gas transmission pipeline, 20 inch in diameter, was
laid, from Bang Yai to North Bangkok Power Plant with capacity 480 MMcf/d. The
construction of Natural Gas Transmission Pipeline from Sai Noi to South Power
Plant was complete and commenced operation in the fourth quarter of 2006. The
project expanded to North Bangkok Power Plant and the Project of improvement of
North Bangkok Power Plant undertaken by the Electricity Generating Authority of
Thailand (EGAT) were scheduled to be simultaneously complete.scheduled to be simultaneously complete.
- The Project of Stand-by Compressor Unit Installation was undertaken by PTT at
the Region V Gas Pipeline Operation Division, Ratchaburi Province, to enhance
stability and flexibility in transmitting natural gas from Myanmar to natural
gas customers in the central region. The operational commencement took place in
early May 2006.
- The Project of Natural Gas transmission Offshore and Onshore Pipeline,No.3
- The Project of PTT Riser Platform Construction (PRP) was complete in early 2008.
- The Project of Laying Natural Gas transmission Offshore 418-kilometer Pipeline,
42 inch in diameter, from PTT Riser Platform to Rayong Province, , with optimum
capacity in transmitting natural gas of 700 MMcf/d., rising to 1,900 MMcf/d,
upon the installation of the Offshore Compressor Unit and operational
commencement of the natural gas transmission in early 2007
-
The Project of Laying Natural Gas transmission Offshore 200-kilometer Pipeline,
42 inch in diameter, from Arthit Gas Field to PTT Riser Platform, with optimum
capacity in transmitting natural gas of 1,500 MMcf/d. The project was finished
and commenced operation in early 2008.
- The Project of Laying Natural Gas transmission Onshore Pipeline, 36 inch in
diameter, 110-kilometer in length, from Rayong Province linking in parallel with
the Natural Gas Transmission Pipeline at the Compressor Station, Bang Pakong,
with optimum capacity in transmitting natural gas of 400 MMcf/d., rising to
1,200 MMcf/d upon the installation of the Onshore Compressor Unit and
operational commencement of the natural gas transmission in early 2006.
The Second Phase of The Project:
- The Project of Laying Natural Gas transmission Offshore Pipeline, 42 inch in
diameter, from JDA Gas Field to Arthit Gas Field, 95 kilometer in length, with
highest capacity in transmitting natural gas of 1,000 MMcf/d. The project was
complete and commenced operation in early 2008.
- The Project of Laying Compressor Installation Unit of Natural Gas Transmission
Offshore and Onshore Pipeline, No.3, to optimize the natural gas transmission’s
capacity. The Onshore Compressor Unit was completely constructed and commenced
operation in early 2007, while offshore one was expected to be complete by mid
2009.
- The Project of Laying Natural Gas Transmission Onshore Pipeline, 36 inch in
diameter, from Wangnoi District, Ayutthaya Province, to Khaeng Khoi District,
Saraburi Province, 80 kilometer in length , with optimum capacity in
transmitting natural gas of 510 MMcf/d, commenced operation at year-end of 2006.
- The Project of Enroute Compressor Installation Unit to boost the capacity of
Natural Gas Onshore Transmission from Wangnoi, as well as the Natural Gas
Offshore Transmission’s capacity from the Gulf of Thailand to Ratchaburi
Province and that of the Project of Natural Gas Transmission Pipeline, Sai
Noi-South Bangkok / North Bangkok, expecting to be complete by early 2010
- The Project of Natural Gas Transmission Onshore Pipeline, 42 inch in diameter,
from Rayong Province to Wangnoi District, Ayutthaya Province, 300 kilometer in
length, with the highest capacity in transmitting natural gas of 1,400 MMcf/d,
expecting to commence operation in early 2011.
The Third Phase of The Project:
- The Project of Compressor Installation on Natural Gas Transmission Pipeline
System, West Side, to optimize the capability of Natural Gas Transmission
Pipeline System, West Side, expecting to be complete in early 2012
Further Investment in the Offshore Gas Spur Lines Project :
- The Project of Offshore Gas Spur Line System, 18 inch in diameter, from the
annex of Arthit Gas Field, North, to the Natural Gas Transmission Offshore
Pipeline System, No.3, 40-kilometer in length, with the highest capacity totally
150 MMcf/d, expecting to be complete in mid 2008
- The Project of Offshore Gas Spur Lines , 24 inch in diameter, from the annex of
Chevron gas Field to the Natural Gas Transmission Offshore Pipeline System, No.
3, 45-kilometer in length, with the highest capacity totally 330 MMcf/d,
expecting to be finished in late 2010
- The Project of Offshore Gas Spur Lines , 24 inch in diameter, from the annex of
Bongkot Gas Field to the Natural Gas Transmission Pipeline System, No. 3, 50-
kilometer in length, with the highest capacity totally 200 MMcf/d, expecting to
be complete in early 2011
- The Project of Offshore Gas Spur Lines , 24 inch in diameter, from the annex of
Pailin Gas Field to the Natural Gas Transmission Pipeline System, No. 3,
40-kilometer in length, with the highest capacity totally 200 MMcf/d, expecting
to be complete in early 2012
