1 Case Studies in Compressor Reliability and Efficiency LNG plant in China and pipeline compressor station in Turkey rely on Siemens solutions

2 Technologies to provide benefitting gas transport Infrastructure related transportation costs Topology and distance define the method The most economic and efficient way to transport natural gas is a pipeline under pressure. While liquefied natural gas (LNG) provides more flexibility than pipeline natural gas (PNG), it bears large fixed costs (Visiongain, 204). Figure compares the cost per energy over distance of gas transported by pipeline (PNG) with the one by ship (LNG). For distances below 3,000 miles, transportation by pipeline is more feasible while for larger distances, transportation by ship becomes more cost-effective. $/MMBTU Gas transportation costs 0 500,500 2,500 3,500 4,500 5,500 Comparison of the cost of transporting gas via line as opposed to using LNG; it assumes a tcf/year (Source: ENI)

10 Our pipeline compressor package offer intrinsic reliability and serviceability The compressor rotors consist of three-dimensional impellers shrunk-on to forged steel shafts, both made from highly corrosion resistant stainless steel. Rotor spacer and stub shaft are not required, eliminating the risk of failure of these components. Siemens forged steel leads to lower the possibility that one of these small components creates a major problem. Our compressor end cover is secured with bolts whereas others compressor plate is secured by means of shear ring design. Siemens approach with bolts provides the benefit of easy access of service. Savings compared to shear ring design to open and close end cover. Solid-shaft rotor Pipeline
