Egis engineers participated in the design of three combined cycle gas-turbine power plants for EDF CIT (the thermal engineering section of France's electricity utility): at West Burton, in the United Kingdom and at Blénod (Meurthe-et-Moselle, France) and Martigues (Bouches-du-Rhône, France). They were commissioned in 2012.
Combining a gas-powered turbine and a steam turbine gives these units far greater energy efficiency (about one-third more) than that of a conventional coal-fired plant, and this with the same quantity of fuel at the start.
The main building is the turbine hall, a large metal construction housing the gas turbine base block and the steam turbine base block. Egis used several 3D design programs for the civil engineering of these facilities: TEKLA® for the drawings for the metal framework, HERCULE® and ROBOT® for calculations.
Egis provided the design for the foundations and for structures bearing static and dynamic (rotating machine) loads, built a complete model of the metal framework with the TEKLA software, and produced the drawings, construction details and quantities for the civil engineering, metal framework and roads and utilities.
