Floating Storage and Regasification Unit (FSRU) for natural gas supply

Abstract

The aim of this Master thesis is the study of Floating Storage and Regasification Unit (FSRU) in order to supply Natural Gas (NG) to end users. In this context the structure of the dissertation is as follows. Chapter 1 introduces Floating Storage and Regasification Units (FSRUs) where Liquefied Natural Gas (LNG) is regasified in order to be distributed to end users. We identify the advantages and disadvantages of these units compared to the corresponding liquefied natural gas onshore terminals. In Chapter 2 we focus on the description and analysis of the processes that take place in FSRUs, from the transfer of liquefied natural gas to the unit, its storage, its regasification and its delivery to the end user. In Chapter 3 we attempt to outline the basic design of a floating unit with storage and regasification capabilities, designing the process flow diagram, simulating two cases of different delivery pressure of natural gas, analyzing the mass-energy balances, identifying the equipment required and examining the safety issues of the station, staff and environment. Finally, the most important key advantages of FSRUs are summarized and the current situation for FSRUs in Greece is presented.
