Adgas feasibility study attracts two

16 December 2005
Two companies - the UK's Costain Oil, Gas & Process and Japan's Chiyoda Corporation - submitted technical and commercial bids on 10 December to Abu Dhabi Gas Liquefaction Company (Adgas)for a feasibility study contract to suggest strategic options for the replacement of its first two liquefied natural gas (LNG) trains on Das island by a single mega train with capacity of up to 8 million tonnes a year (t/y - MEED 4:11:05).

The six-month study - called operability and vulnerability of trains 1 and 2 - will involve carrying out a techno-economic analysis of the ageing production units and evaluating the best available technology for a new LNG train. The contract will be carried out in two phases.

Following extensive debottlencking, the Das island liquefaction plant - comprising three trains - has total capacity of 6 million t/y of LNG. Trains 1 and 2 were commissioned in 1977; train 3 started production in 1994.

Established in 1973 to convert gas extracted from Abu Dhabi's offshore oil fields, Adgas is a joint venture of Abu Dhabi National Oil Company (ADNOC - 70 per cent), Mitsui & Company of Japan (15 per cent), the UK's BP(10 per cent) and Totalof France (5 per cent).

Along with the proposed LNG expansion, Adgas also plans an upgrade of the existing production facilities. An award is due for the $15 million engineering, procurement and construction (EPC) contract to upgrade the filtration systems of its LNG trains. Four contractors submitted technical and commercial bids in late November for the contract.
