1 INTRODUCTION
The growth of the gas turbine application in recent decades has been brought about most significantly by four factors:
1- Metallurgical advances that have made possible the employment of high temperatures in turbine components (especially turbine blades) and the combustors.
2- The cumulative background of aerodynamic and thermodynamic knowledge (especially from aircraft and spacecraft industries).

Future LNG plants would be "all aero-derivative" driven or "all electric" driven. Practical notes and latest developments on LNG refrigeration compressor train design, driver selection and optimization are discussed. Useful notes and new technologies on "all electric" solution and associated power plant are also described.
Torsional analysis

Amin Almasi
A comprehensive torsional analysis should be carried out for a complex compressor string. Various modes of torsional vibrations should be extracted and analyzed. Complicated combinations of effects in various steady state and transient operating cases should be considered. Complete practical notes and latest achievements on torsional design, train arrangement, component selection, coupling sizing and vibration studies are described.
