Tangguh LNG is moving forward with expansions plans. The Tangguh Expansion Project will add a third LNG process train (Train 3) and 3.8 million tons per annum (mtpa) of production capacity to its existing facility, bringing total plant capacity to 11.4 mtpa. The project also includes two offshore platforms, 13 new production wells, an expanded LNG loading facility, and supporting infrastructure.
The Tangguh facility is located in Teluk Bintuni Regency, Papua Barat Province of Indonesia and consists of offshore gas production facilities supplying two 3.8 mtpa liquefaction trains that have been in operation since 2009. Tangguh is operated by BP Berau Ltd. (100% owned by BP) with two other wholly-owned BP subsidiaries – BP Muturi Holdings B.V. and BP Wiriagar Ltd. – giving the company a 37.16% share in Tangguh LNG.
The Tangguh Expansion Project will play an important role in supporting Indonesia’s growing energy demand, with 75% of the Train 3 annual LNG production sold to the Indonesian state electricity company PT. PLN (Persero). The remaining volumes are under contract to Kansai Electric Power Company in Japan, the other foundation buyer for Train 3.
The Tangguh Expansion Project will also bring a positive contribution to Indonesia and the Papua Barat Province starting in 2016, supporting economic growth and providing 10,000 jobs over the project period.
GE Oil & Gas was awarded the contract to supply gas turbine-driven compressors for Train 3. The low pressure/medium pressure mixed refrigerant (MR) string will include one horizontally split centrifugal compressor for low- pressure MR and one barrel type centrifugal compressor for medium pressure MR, driven by a GE MS7001EA gas turbine, and a helper/starter steam turbine. The propane/high pressure MR string will include one horizontally split centrifugal compressor with side streams for propane and one barrel centrifugal compressor for high pressure MR, driven by a GE MS7001EA gas turbine, and a helper/starter steam turbine. GE Oil & Gas will also supply heat recovery steam generator for each of the two strings.
The components of the turbo compressor strings will be manufactured at GE facilities in Greenville, South Carolina, USA and Florence, Italy, where the train will by assembled and load tested.
GE provided the original equipment for Trains 1 and 2 when the plant was first established.
According to GE, Train 3 will be fully digitally-enabled, including advanced sensors and monitoring capabilities, to allow continuous equipment care to safely maximize availability. The equipment will be ready for shipment to Indonesia in mid-2018.
Indonesia is one of the leading suppliers of LNG in the region and one of the fastest growing economies in the world. Energy consumption grew 3.9% in 2015, having nearly doubled over the last 15 years. The majority of the gas produced by the third liquefaction train will provide energy for the Indonesian domestic market.
