The bearing component comprises an external cylindrical member having an outer bearing surface and an inner cavity, and internal cylindrical member, arranged in the inner cavity of the external cylindrical member and substantially coaxial thereto. The external cylindrical member and the internal cylindrical member form a gap therebetween. A resilient damping feature is arranged in the gap.

The method is used for uniforming temperature in a shaft supported by a fluid bearing during rotation of the shaft; a journal portion of the shaft is located inside the fluid bearing; at least one passage is provided inside the shaft at least along the journal portion so to cross it; at least one flow of heat-exchange fluid is established in the at least one passage; the method allows to overcome the problems due to the 'Morton effect'. A bearing system implementing the method is advantageously used in a turbomachine.

A drive system for driving at least one compressor is described. The system comprises a gas turbine configured and arranged for driving the compressor. The gas turbine has a hot end and a cold end. A load coupling for connection of said gas turbine to the compressor is arranged at hot end of the gas turbine. An electric motor/generator arranged at the cold end of the gas turbine. The electric motor/generator is electrically connected to an electric power grid and is adapted to function as a generator for converting excess mechanical power from the gas turbine into electrical power and delivering the electrical power to the electric power grid, and as a motor for supplementing driving power to the compressor.
