Always monitor your LNG storage
Liquefied natural gas terminals need to both handle and store multiple grades of LNG, and boil-off means, the chemical composition of any stored LNG is in constant flux. Therefore, it is vital to monitor the possible development of stratification, and to be warned of any unstable stratifications that might occur.
instruments to prevent rollover
It is vital that LNG tanks have precise instruments that measure variations in temperature, density and levels. Incoming LNG can be of widely varying quality, and there is always the key risk of stratification of the LNG, which can evolve into ‘rollover’ with severe consequences.
Land-based tanks that store liquefied natural gas are an expensive investment, and it is essential that they remain fail-proof.
