Wartsila (formerly Whessoe)
LNG Tank Gauging Systems

Wartsila Tank Control Systems (formerly Whessoe S.A.) specializes in tank gauging systems for LNG and LPG applications. LNG has evolved into a major source of energy for the future, and Wartsila Tank Control Systems can supply your site with the only turnkey LNG tank gauging and storage management system available. Through Wartsila Tank Control Systems’ LNG Master (sold under license by Gaz de France), Warsila can offer dramatic cost savings through proper LNG stratification management.

Wartsila Tank Control Systems also manufactures unique "in-tank" LPG safety shutoff valves that insure that your safety shutoff valves remain intact and operational, even in the event of an accident that damages or destroys piping, valves and controls that are external to the tank.

LNG Tank Gauging and Management Systems

Safety

LNG is a "dynamic" liquid. If not controlled, it can generate a dangerous situation.

Inventory Management

Storage of LNG is a business. Exact data on mass contents are imperative.

Cost Control

Reliable, accurate data helps operators to take sound operational decisions that directly impact the business results.

Wartsila Tank Control Systems is the world's dominant supplier of LNG tank gauging systems, offering the only complete, turnkey LNG tank gauging solution available. LNG densities and temperatures, LNG liquid levels, tank temperature probes and LNG leak sensors are all monitored on a fully redundant "LNG Manager" communications platform providing full system information and management capabilities to the operators. "LNG Master", developed by Gaz de France, provides LNG stratification management and roll-over prediction that allows operators to utilise stratification as a tool to reduce LNG boil-off and dramatically reduce LNG storage operating costs!

LNG Master Stratification Management Software

Developed by Gaz de France to optimise the handling of LNG storage in terms of safety and cost reduction through:

• Prediction of LNG ageing
• Best assessment of LNG tank filling operations
• Prediction of stratification evolution and roll-over phenomenon
• Coupling of boil-off rate with the operating pressure and its variations
• Taking into account tank and site gas recovery and safety devices (compressors, flare, safety valves, rupture disk)
• Specification of operating scenarios for the pressure, unloading of carriers, site emission and LNG transfer between tanks
