Liquefied Natural Gas (LNG)

Liquefied natural gas (LNG) is the main product produced by Brunei LNG.

Natural gas is mostly supplied by Brunei Shell Petroleum (BSP) which operate three major offshore fields. The largest is South-West Ampa field, about 10 kilometres off Kuala Belait. The other producing fields are Fairley and Gannet. In 1999, natural gas is also supplied to Brunei LNG by Total (a BBJV company) from Jamalul Alam and Maharaja Lela fields. As of August 2003, BSP has a new gas field (Egret) producing to Brunei LNG.

The other product produce at the BLNG plant is Liquefied Petroleum Gas (LPG), which is bottled into canisters and sold as domestic cooking gas.


There are five liquefaction trains, each capable of processing 9700 m³ of gas per day. This gives an annual plant capacity of around 7.2 million tonnes of Liquefied Natural Gas (LNG). The LNG is stored in specially designed tanks prior to shipping by dedicated tankers to the customers in Japan and the Asian region. Part of the feed is conditioned and exported to the Department of Electrical Services (DES) power plants located in Lumut and near the state capital, Bandar Seri Begawan.

Liquefied Petroleum Gases (LPG) is produced as a by-product. The LPG is used in the LNG process and is bottled in the Bottling plant for domestic sales by BSM.

LNG Chain

Gas Supplier

A complex network of platforms off Brunei Darussalam’s coast produce gas, compress it where necessary, and pipe it to LNG plant at Lumut.

Most of the gas for LNG comes from three fields in Brunei Shell’s western area of operation, South – West Ampa, Fairley and Gannet. Beginning 1st April 1999, gas to BLNG will come from Jamalul Alam and Maharaja Lela fields of BBJV.

Gas Liquefaction

At the LNG Plant on the coast of Lumut five liquefaction trains remove impurities from the gas, dehydrate it and cool it to its liquid state at -162°C when it occupies one six hundredth of its volume as gas.

LNG Shipping

LNG is delivered to customers every two or three days, over 14-day round trips, including one-day loading in Lumut, six days sailing to Japan and another day unloading before the six-day return leg.

The vessels measuring 147,000m3 – 154,800m3 are managed by Brunei Gas Carriers Sdn Bhd.

LNG Customers

Brunei Darussalam’s LNG is delivered to terminals near Tokyo and Osaka, Japan’s two largest cities. It is regasified to be used as city gas, and for electricity generation. Brunei Darussalam accounts for 15% of Japan’s LNG imports.
