The requirements of contemporary society for energy is constantly increasing in the last decade. Important sources of energy such as oil and coal, are becoming less and less attractive because of the sudden price increases and the existing environmental consequences.Nevertheless, natural gas, and more specifically the Liquefied Natural Gas (LNG), comes to fill the ever increasing demands of modern society and to meet the growing global energy demand. It has proven to be cost effective, attractive from of Environmental terms, easy to use and is a dominant choice for energy production. On a global scale, the most important way of natural gas transport is carried out in gaseous form via pipelines. However, the transportation of liquefied natural gas by ship LNG is, perhaps, the fastest growing energy transportation system in the world, due to innovative solutions in international logistics and the constant technological developments concerning liquefied natural gas. The subject of this thesis is the supply chain energy sources via LNG tankers. In the first chapter are presented the natural gas, the liquefied natural gas, the historical background, the properties and the use of LNG, its situation on the global market, and the Greek fleet.The second chapter describes the technical characteristics of LNG Tankers, their evolution in construction, the types of LNG tanks, the manufacturers, design elements of LNG tankers, the life cycle of an LNG Tanker and the construction requirements.Subsequently, the third chapter analyzes the supply chain of liquefied natural gas, and more specifically, its stages, the security policies that must be implemented, the safety regulations in Greece, the types of contracts and costing in LNG chain. The last chapter performes a case study concerning the Liquefied Natural Gas Terminal in the Adriatic, the economic benefits, the configuration of LNG prices and a SWOT analysis for the LNG industry. This study is completed with the conclusions derived from the literature review and the literature.
