In 2008, the WTI Crude Oil Index reached a maximum level of USD 130/bbl and the LNG spot price was 25 USD/MMBTU. An LNG price as high this would appear to support a trend toward investment in new LNG Liquefaction Plant projects. However, an abundance of FIDs in new projects was not seen; in fact, the number of FIDs was very limited. The principal reasons have been the inflated plant cost and uncertainty of future economics as the balance of supply vs demand for the energy, especially the LNG trade. Baseload LNG projects require a very large amount of investment for exploration/production, upstream facilities including submarine pipelines and the LNG liquefaction plant itself. Projects are organized as joint ventures or a multi-shareholder group from the standpoint of risk-sharing and it is difficult to achieve the common direction required for the project to smoothly proceed. Meanwhile, numbers of small/medium gas wells/ reservoirs remain stranded and are not developed for economic and/or technology-based reasons. In order to contribute to solutions for this business area and to break through the current inactive market, a small/ medium size LNG liquefaction plant with the clear concept of "SPEED-REPEAT-COMPACT" is proposed by LNG super-builder JGC and Top LNG Process Licenser APCI. A brief explanation and target is provided.
