Germany’s Siemens Energy has won a $40m contract to design and supply the power system equipment for a new natural gas liquids (NGL) train at Ruwais in Abu Dhabi’s Western Region.

The company was awarded the contract by the main engineering, procurement and construction (EPC) contractors on the project, South Korea’s GS Engineering & Construction and the UK’s Petrofac, Siemens said in a 20 July statement. The ultimate client on the scheme is state gas developer Abu Dhabi Gas Industries (Gasco).

The NGL train, the fourth to be built at Ruwais, is scheduled for completion in March 2012. Siemens will supply power and distribution transformers, high, medium, and low voltage switchgears and motor control systems.

The award comes almost exactly a year after the GS/Petrofac consortium was awarded the $2.1bn contract to build the NGL plant at Ruwais. The deal was announced on 16 July 2009.

The project is part of Gasco’s wider $10bn integrated gas development. Under the scheme, Gasco will transfer high pressure gas from the offshore Umm Shaif field to new onshore processing facilities at Habshan and Ruwais via Das island.
