Transcripción del abstract original del autor: Who doesnt́ know where BLNG is located? For those –hopefully few- amongst us, the Brunei LNG plant is situated in Lumut, in the Belait District of Brunei Darussalam, where its coastal plot and four km long jetty face North towards the South China Sea. The plant was commissioned in 1972 and has recently celebrated its 30th year of operation. BLNG is a joint venture between the Brunei Government (50%), Mitsubishi Corporation (25%) and Shell Group (25% - also Technical Advisor). BLNG is now in the middle of its second 20-year contract with customers in Japan and South Korea. In 1999 BLNG launched the Asset Reference Plan (ARP) campaign, which provides the technical and operational framework to stretch the lifetime of the plant with a third 20-year sales commitment till 2033 and to meet the aspiration of the BLNG shareholders for increased sales flexibility in the years ahead. Upon completion in 2008, the ARP will create maximum value from an aged but rejuvenated asset base, including an increase in its LNG production capacity of some 5 percent beyond its present production limits. Current gas reserves studies indicate good confidence that the additional (non-committed) feedgas, necessary for the 20-year extension period 2013-2033, can be secured. Meanwhile, expectations of significant new gas reserves being found in future deep-water exploration offshore Brunei have prompted initial studies into a plant expansion project with a new, world-class LNG train. This new LNG train (Train 6 or T6 for short) would add some 4 MM tpa to the BLNG production capacity and deliver continuing market growth in the Asia-Pacific region and a further contribution of BLNG to the sustainable development of Brunei Darussalam. In this paper the present BLNG plant configuration including major plant rejuvenation activities (ARP) are briefly discussed to set the scene for the main topic, a discussion of the technical options and challenges involved in an expansion of the BLNG plant with a state-of-the-art, sixth LNG train.
