LNG Manager

LNG Manager monitors and displays real-time, tank detail information (level, temperature, density, trends), alarm events and summary (periodic or on-demand reports), and information for shutdown alarms. It uses different standard databases for volume correction calculation. It allows access to maintenance menus in order to configure connected gauges and transmitters.

LNG Expert

The LNG Expert^® software is based on Gaz de France's LNG Master. It continuously monitors data and calculates the expected evolution of the stratifications (if any). LNG Expert:

• Predicts stratification and roll-over phenomena.
• Facilitates operations for LNG storage tanks.
• Displays tank level, layer height, average density and temperature per layer.
• Indicates the status of the plant’s safety devices.
• Generates automatic alarms in case of roll-over, without any operator intervention.

It detects the occurrence of a roll-over within the next 30 days (configurable from 1 to 30 days), showing the operator the:

• Tank where roll-over is expected.
• Remaining time to roll-over.
• Predicted boil off gas (BOG) level during roll-over.
• Predicted pressure (rise) during roll-over.

It handles all grades of LNG, and automatically calculates their actual chemical composition.
