Massive integrated gas development in Abu Dhabi

Abu Dhabi has launched the tendering process for the long-awaited onshore portion of its massive integrated gas development (IGD), which is aimed at significantly boosting the emirate's offshore gas production.

The objective of the multi-billion-dollar development is the production and transfer of more than 700 million cubic feet a day of high-pressure gas from the offshore Umm Shaif and Khuff reservoirs to new processing facilities at Habshan and Ruwais onshore.

A total of 25 local and international engineering, procurement and construction contractors have been invited to submit prequalification applications by 29 February for the five main onshore packages.

Four of the packages fall under the responsibility of Abu Dhabi Gas Industries Company (Gasco). The fifth will be tendered by Abu Dhabi Gas Liquefaction Company (Adgas).

Gasco's contracts are: package 1, covering the Habshan 5 gas processing plant; package 2, covering the Habshan plant's offsites and utilities element, including water and nitrogen provision; package 3, covering a fourth natural gas liquids (NGL) recovery train at Ruwais; and package 4, covering liquefied petroleum gas storage tanks at Ruwais.

Adgas's contract involves the construction of process units and utilities on Das Island, including a gas dehydration and compression facility.

In addition, Gasco is prequalifying local contractors for three civil works contracts, covering early works and non-process buildings at Habshan, and early works at Ruwais. A pre-tender meeting for all of the work will be held on 17 February.

The IGD's offshore portion is expected to be tendered later, with the work handled by Abu Dhabi Marine Operating Company (Adma-Opco). It covers the installation of a platform to be built adjacent to the Umm Shaif super-complex, and an associated gas transfer pipeline to Das island.

The additional gas from Umm Shaif and Khuff will be used as feedstock for industrial processes, as well as power generation requirements in Abu Dhabi and the northern emirates. The IGD project is also expected to deliver more than 10,000 tonnes a day (t/d) of NGLs and more than 4,000 t/d of sulphur. The whole project will take about four years.

The front-end engineering and design (FEED) contractor on the IGD is the US' Fluor Corporation. The US' KBR is the project management consultant for the FEED phase. Source
