Companies are preparing for Abu Dhabi Gas Liquefaction Company (ADGAS) to tender the engineering, procurement, and construction (EPC) contract for a revived package that forms part of a project to expand its Integrated Gas Development (IGD).

Formal expressions of interest in the project have been submitted and the contract is expected to be tendered in the fourth quarter of 2017, according to industry sources.

The project includes adding two booster compression trains, three dehydration trains and two amine-based fuel gas treatment units – as well as associated facilities.

It is estimated that it the EPC contract for the project will be worth around $1bn.

At least ten companies have submitted formal expressions of interest ahead of the contract being tendered.

These include:

The package was originally tendered in March 2015 as one of five packages that formed the Integrated Gas Development Expansion project.

Commercial bids for the EPC contract were submitted in December 2015, but the project was subsequently put on hold and the contract was never awarded.

All of the other packages are currently in the execution phase.

The other packages are:

The expansion project was designed to increase capacity so an additional 200-400 million cf/d of offshore gas could be processed onshore.

Gasco completed the initial $11bn IGD project in 2013.

The original IGD project allowed Gasco to transfer 1 billion cubic feet a day (cf/d) of high-pressure gas from the offshore Umm Shaif field via Das Island to onshore processing facilities at Habshan and Ruwais.
