Abu Dhabi Gas Industries (Gasco) is expected to float the tender for the $1bn expansion of its Integrated Gas Development (IGD) in the summer after the front-end engineering and design (feed) study is complete.
US engineering group Fluor was awarded the feed for the project in 2012 and is expected to complete the work in the coming months.
Gasco completed the initial $11bn IGD project in 2013. The development allows Gasco transfer 1 billion cubic feet a day (cf/d) of high-pressure gas from the offshore Umm Shaif field via Das Island to new onshore processing facilities at Habshan and Ruwais.
The proposed expansion will see an additional 200-400 million cf/d of offshore gas processed onshore.
The engineering, procurement and construction (EPC) phase is expected to be tendered in three separate packages: offshore development; Das Island to Habshan offshore pipeline; and Ras al-Qila to Habshan onshore pipeline.
The IGD is part of Abu Dhabis significant investment programme to boost gas supplies to meet growing demand.
The emirate expects to complete the $10bn development of the onshore Shah sour gas field early in 2015, while a second sour gas development is planned at the Bab field.
