Project Profile
Value: US$2.42 billion
Location: From the gas reserves in the Thai-Malaysia joint offshore development area to
Songkhla in Thailand
Length: 323 kilometres
Trans Thailand–Malaysia Gas Pipeline (TTM) is a gas pipeline linking suppliers in Malaysia to consumers in Thailand. It is a part of the Trans-ASEAN Gas Pipeline project The Trans Thailand Malaysia (TTM) gas pipeline and separation project was instigated in February 2000 to transport and process natural gas from the gas reserves in Malaysia\'s joint development area (JDA). The JDA is approximately 255km east of Songkhla Province in the Gulf of Thailand and covers an area of 7,250km². The TTM project consists of the Gas Pipeline Project and the Songkhla Gas Separation Plant (GSP) Project geared to making LPG. The Malaysia-Thailand Joint Authority (MTJA) was established in 1990 to oversee and plan joint activities relating to development of the JDA. Thailand and Malaysia shared the costs of the US$2.42 billion, 255km pipeline to transport the gas to Thailand, where it is processed at the new GSP to be built on the coast at Chana. The final stage in the network is a further 93km pipeline extension to the border to link into the Malaysian Peninsular Gas Utilization pipeline at Changlun in Kedah.
The pipeline consists of three offshore and onshore sections. The first section consists of a 55km length, 28in diameter pipeline connecting the offshore block A-18 and block B-17 gas reserves in the JDA. The second section is 277km long and consists of a 34in diameter offshore gas pipeline designed to withstand 2,080psig (pounds per square inch gauge) pressure with a maximum transmission capacity of 1,020mmscfd (millions of standard cubic feet of gas per day), which is to be laid from block A-18 to the gas separation plant in Songkhla. The third section of the pipeline is 96.5km overland from the GSP and will connect with the Malaysian PGU III pipeline system (gas grid). This section of the route consists of a 36in diameter pipeline designed to withstand 1,000psig pressure with a maximum transmission capacity of 750MMSCFD. An eight inch diameter pipeline capable of transmitting 1,166t/day of liquid petroleum gas will also run parallel to the main natural gas pipeline from the gas separation plant to Prai Depot in Malaysia. The JDA\'s gas reserves will last for between 14 and 22 years. The pipes have been designed to have an operational life of at least 40 years to ensure they will be operable for the full length of the project.
