One of Abu Dhabi's three LNG trains on Das Island is to be shut down for maintenance for up to 50 days in November this year, amid efforts to develop the site’s ageing facilities.

The announcement came courtesy of the Abu Dhabi National Oil Company (ADNOC)'s LNG subsidiary ADGAS.

The company plans to shut down Train 3, the largest of the three units with an LNG production capacity of 4 million tonnes per year (tpy). The other two trains have a capacity of 2 million tpy each.

Efforts to develop new parts of Abu Dhabi's large gas reserves for domestic consumption have been slow, as much of them are highly sour and require innovative and expensive technologies to commercialise them. As the current downturn subsides, domestic demand for gas in both Abu Dhabi and neighbouring Dubai will have to be catered for.

The company is also studying suggestions from Japanese engineering contractor Chiyoda Corp. concerning how the old LNG facility could be maintained, with either a thorough overhaul of the two oldest, smaller trains or their replacement by one new 4-million tpy train.
