Open and redundant solutions for LNG inventory management

LNG tank gauging & operational safety

The Tankvision LMS inventory management system enables reli able, real-time LNG management. It has an open and redundant data system and is a multi-user system with remote access capability. • Rollover prediction software al lows you to visualize the changing temperature, density and strati fied layer thickness in a tank. The software predicts rollover and

enables upfront counter-measures. The change in boil-off rate and vapor pressure can also be visual ized with time. • The cool down and leak detec tion sensors, located around the base, sides and roof of the LNG tank are used to detect any abnormalities in the shell insula tion that may cause product leak. They are particularly used during the cool down and operation.

• Constant primary level measurement or redun dant operation with high precision Proservo level gauge • 24/7 plant safety with independent servo or radar gauges for high level alarm • SIL2/3-certified • Monitor density changes in different LNG layers with Level Temperature Density (LTD) gauges • Manage LNG gas boil-off with highly accurate pressure transmitters. Multi-point temperature measurement is used for cool down and leakage detection

A typical liquefied natural gas tank requires a range of instruments to measure liquid level and density, liquid and vapor temperature and pressure, skin temperature and more. For safe operation you must also make sure that two layers of different LNG densities are not rapidly mixing with the effect of releasing large amounts of gas – known as rollover. Ensure safe operation of your plant and the highest inventory trans parency with best-fit instrumentation for LNG storage tanks.
