‘Mega-Structures’ To Provide Power

Six plug-and-play modules will power operations, gas compression for Abu Dhabi field; GE expands Italy construction facility

Posted on January 21, 2014

GE Oil & Gas has received a contract to provide a turnkey turbomachinery solution to Petrofac Emirates for the Upper Zakum UZ750 field in Abu Dhabi. Petrofac Emirates is the engineering, procurement and construction (EPC) contractor selected by developer ZADCO (Zakum Development Co.), an Abu Dhabi National Oil Co. subsidiary in which ExxonMobil and Japan Oil Development Co. also are shareholders.

The equipment will be delivered in the form of a stand-alone, plug-and-play “modules,” each weighing more than 1360 tonnes and measuring 44 m long, 20 m wide and 24 m high. The six structures – which will ship intact from GE’s construction facility in Avenza, Italy, to an artificial island located 80 km offshore of Abu Dhabi – will each house a turbogenerator train that will provide electric power to ZADCO’s oil production facilities on the island, including pumps and gas compressors.

The modules each feature a 43 MW GE 6B gas turbine and electric generators that are fully engineered, equipped, packaged and tested.

To support the ZADCO project, GE is investing more than US$12 million to expand the Avenza yard’s assembly and testing capabilities. When completed at the end of 2014, GE said the Module Construction Yard will cover 140 000 m2, almost four times its original size. The finished yard will have enough platform foundations to assemble 10 modules at the same time, the company said.

Following their assembly in Avenza, the modules will be shipped to Abu Dhabi in 2016.
