Tanks Inventory Information System


It is necessary to know the plant’s present resource levels before executing the production plan. gomsTIMS™ provides the detailed information in real-time on the plants’ tanks farm inventory by interfacing with the plant’s Automatic Tanks Gauging (ATG) system and other modules in an integrated system, such as blending control, custody transfer, planning and scheduling of material movement, etc.


Tanks Inventory Management System (gomsTIMS™) can be used very effectively for:

  • Custody Transfer
  • Estimation of Hydrocarbon Losses
  • Plant Inventory Calculations
  • Liquid Assets Management
  • Compliance with Local environmental regulations
  • Blending of products and crude oil


  • Online real-time information of plant inventory for material movement
  • Planning and scheduling of tank farm activities and maintenance
  • On-line and off-line tank farm reports for management and operations
  • Online Management and accounting of multi-customer products inventory


  • Configuration & Security
    • Multi-level user access security and individual user configuration and access control
    • System configuration by tank farm engineer and individual customization of user preferences by operator
    • Import tank parameters from Excel worksheets for data initialization.
