The tranport of natural gas by pipeline from gas fiel tothe town or industrial sites in most case is impossible, so there is need to transport LNG by ship. At the terminal of arrival a regasification process of LNG, which is liquefied near well-head, returns it back to gas state before its transport in the pipelinenetwork. This paper deals with the results of feasibility studies on ventures based on an appropriate thermo-economic analysis of improved cycles (CHP Cycles: the top Cycle is a convevtional Gas Turbine open Cycle fed by natural gas and the bottom Cycle is an improved Gas Turbine closed cycle working with Helium or Nitrogen gas). The analysis shows the convenience and the profitability of the processes proposed. A careful analysis of the technology involved was also performed, this last is based on cryogenic equipement of improved design used in the regasification process.
