INPEX Corp. has begun front-end engineering and design (FEED) of its 9.5-million tonne/year (tpy) Abadi LNG project in Masela block, offshore Indonesia. FEED work is being carried out under multiple contracts: one each with PT Technip Engineering Indonesia and PT Saipem Indonesia for the project’s floating production, storage, and offloading (FPSO) vessel and two with PT Worley SEA Indonesia covering the natural gas export pipeline from the FPSO to the shore-based LNG plant and the project’s subsea, umbilical, riser, and flowline system, respectively.
The FPSO 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.” In this method, FEED work and engineering, procurement, and construction (EPC) work will be awarded to the same contractor consortium, effectively assigning it to the contractor consortium that delivers technically and commercially superior FEED services, according to INPEX. INPEX intends to use the dual FEED method for the LNG plant as well.
INPEX Masela Ltd., an INPEX subsidiary, operates the project. The company is targeting a 2027 final investment decision on Abadi LNG. Its partners are PT Pertamina and Petroliam Nasional Berhad (Petronas), holding a combined 35% interest.
The project will also supply 150 MMcfd of gas to the local market. Masela block holds roughly 10 tcf of recoverable gas reserves.
