INPEX CORPORATION (INPEX) announced that the Abadi LNG Project (hereinafter “project”) in the Masela Block in Indonesia has commenced Front End Engineering and Design (FEED) work for the project’s onshore LNG plant (OLNG) by awarding an OLNG contract package. This follows the project’s earlier FEED package awards* for floating production, storage and offloading (FPSO); subsea umbilicals, risers and flowlines (SURF); and the gas export pipeline (GEP). Consequently, the project has completed the awarding of all four FEED packages. The project is operated by INPEX Masela, Ltd., an INPEX subsidiary.
* Abadi LNG Project in Masela Block, Indonesia Commences FEED
The FEED work involves reviewing and defining the specifications of OLNG. The OLNG contract package consists of a “dual FEED” method involving two contractor consortiums that will work in parallel but separately to ensure a competitive environment is maintained. One consortium consists of PT JGC Indonesia (lead contractor) and PT Technip Engineering Indonesia, while the other consists of PT KBR Indonesia (lead contractor), Samsung E&A, Co. Ltd. and PT Adhi Karya (Persero) Tbk. In this method, FEED work and Engineering, Procurement and Construction (EPC) work will be awarded to the same contractor consortium, effectively assigning EPC work to the contractor consortium that delivers technically and commercially superior FEED services. The FEED work includes a scope related to carbon capture and storage (CCS).
The project’s annual LNG production volume is expected to reach 9.5 million tons, equivalent to more than 10 percent of Japan’s annual LNG imports. The project is expected to contribute to improving energy security in Indonesia, Japan and other Asian countries and generate a stable supply of low-carbon energy over the long term, based on its world-leading gas field properties and plentiful reserves enabling efficient development as well as the project’s CCS component.
INPEX expects the FEED work to contribute to the expansion of its natural gas and LNG business, and reduction of its own GHG emissions as outlined in INPEX Vision 2035 announced in February 2025. In addition, the project is expected to contribute significantly to the economic development of the eastern part of Indonesia in particular and help achieve Indonesia’s goal of reaching net zero CO2 emissions by 2060. INPEX is also committed to further strengthening its business in Indonesia and will continue to actively engage in this effort.
