Hydrodynamic and Dynamic Model of Liquefied Natural Gas Transportation System

A comprehensive hydrodynamic model for a liquefied natural gas (LNG) tank of a Floating Storage and Regasification Unit (FSRU) regasification terminal operating in transport mode was presented. The model is validated using technical data that characterize real-life technological regimes of LNG regasification process in the Floating Storage and Regasification Unit (Klaipeda LNG Terminal, Lithuania). During the start-up period, (hydro-) dynamic processes were studied as LNG is pumped from the storage tank to the intermediate buffer tank (suction drum). This mathematical model is released with a particular software package using Fortran programing language (MICROSOFT VISUAL STUDIO package) and MATLAB R28a. The main idea was to investigate high-speed processes and their influence on hydrodynamic and dynamic processes and obtain energy losses in the pipe system.
