IPSs Tank Inventory System (TIS) provides a uniform approach for managing tank inventory information and single-window interface to all major gauging systems (e.g., Varec, Saab, L&J, Enraf).  TIS calculates, displays, and historically archives all level, volume, temperature, quality, operating state, and alarm data related to a tank and its contents.   TIS provides information to the operator to safely operate the tank, and to all other ROMSS and external operational and decision support systems.

TIS stores strapping tables, performs ASTM/API table volume & density corrections, estimates flow rate from level changes, continuously updates Time-to-Completion and Time-to-Limits, provides level & tank operational states & alarms, and generates standard tank detail, pool, and midnight inventory reports.  An optional EPA tank emissions module provides online monitoring, calculation, forecasting, & reporting.

TIS provides accurate, reliable, and accessible inventory and movement data management and reporting to facilitate improvements in:

• Planning, scheduling, & operation
• Mass balance reconciliation, yield accounting, & stock loss control
• Inventory accounting and cash flow management
• Spot & hedge market decision support
• Tank farm asset management (utilization & efficiency)
• Safety & environmental compliance and risk management
