Athens-based Consolidated Contractors Company (CCC) has won a contract to construct onshore facilities for Qatar’s Barzan gas field development.

The engineering, procurement and construction (EPC) contract was awarded to the company by Japan’s JGC, and is estimated to be worth $330m, according to a source close to the project.

JGC is the main contractor for the onshore package of the project, valued at around $1.7bn. The ultimate client for the project is RasGas, a joint venture between state-owned Qatar Petroleum (QP) and US energy major ExxonMobil.

The contract obliges CCC to complete construction work relating to piping fabrication and erection, civil works, steel structure erection, equipment erection, electrical and instrumentation installations, painting and insulation.

JGC is constructing two gas processing trains, each with a capacity of 850 million cubic feet a day (cf/d), to be completed by 2013.

Barzan is a response to increasing domestic demand for power, which is generated from gas. It is the last extraction project to be approved by the Qatari government, and moratorium on further production is in place.

The project scope has grown fourfold from the initial target for the 1.7 billion cubic feet a day (cf/d) first phase, with plans now in place for six gas trains to be developed in three phases by 2015. Aside from phase one, a second phase will deliver 2 billion cf/d and a third up to 2.5 billion cf/d.
