The functions of an LNG terminal are:
reception, storage, regasification, supply of natural gas to the grid and the distribution of LNG.
Before an LNG carrier starts to unload, a detailed safety checklist is run through. The liquefied gas is pumped from the ship through an unloading installation and a short pipeline to storage tanks on land. A closed vapour return system ensures that there is no under-pressure or overpressure in the tanks. Unloading is efficient and safe.
The envisaged LNG storage tank consists of a metal inner tank and a concrete outer tank. An insulation layer between the two keeps the temperature at approximately -160° C. This ensures that virtually no vapour or condensation forms on the tank’s outer surface. All connections to the tank will be made via the roof so that the tank will not empty even in a calamity. This design is based of proven technology.
Regasification and transmission
After regasification of the LNG, the natural gas will leave the terminal via a undergrond pipeline connected to the gas transmission network or it could be used by the nearby industry. Since the LNG terminal is a closed system, no gas will be emitted into the atmosphere during normal operation.
Distribution of LNG
The distribution of LNG from the terminal to other receiving facilities can be performed via the truck loading facility and via vessels and barges which are (re)loaded at the jetty. A railcar loading facility could also be an option.
