Fixed Interlocks

TIS Tank Inventory System

• Uniform approach to managing gauging systems (Varec, Saab, L&J, Enraf, HTGs..)

• Strapping table database

• ASTM/API table volume & density corrections

• Flow-rate calculations from level changes

• Level & tank operational states & alarms

• Standard tank detail, pool, & midnight inventory reports

• EPA (AP42) tank emissions calculation module

OMM Order & Movement Management

• Management, real-time monitoring, & reporting for all orders/movements.

• Bridges work & data flow gaps between marketing, planning & scheduling, operations, & accounting.

• Handles all standard tank, unit, pipeline/dock/rack terminal movement categories, including blending operations, and other complex orders

• Sets TIS stop gauges & operational states

• Calculates/validates input & volume/ weight moved calculations based on all available meters & gauges

• Composition tracking (TCT), quality integration (TQI) modules & ownership management modules

OMM Dock Receipt/Shipment Balance

MAB Material Accounting Balance

• Extension of TIS & OMM designed for the inventory/yield accountant

• Review, balance, & close accounting data for a defined date range

• Identify volume & mass imbalances for specific areas, products, owners, or equipment

• Validate/correct TIS/OMM data

• Introduce gain/loss/rebrand transactions manually or use proportional reconciliation function

• Perform daily fenceline balance & control check instrument vs. custody transfer measurements prior to full refinery reconciliation

MAB View Interface

Significant Imbalance

TIS/OMM/MAB ErrorSolver Yield Accounting Integration

• Midnight Inventories

& Compositions (all tanks, caverns, pits, piles, & lines )

• Midnight Cut-Off

Movement Volumes & Weights (all receipts, internal transfers, blends, & shipments; w/ custody transfer measurements where available)

Offsites Operations Management & Yield Accounting

●Best Practices:

●Streamlined business processes and

integrated work/data flow between

scheduling, operations, & accounting

●Real-time tank inventory and movement

operations monitoring applications

●Operations validation of field instrument vs.

custody transfer measurements

➢ Accounting balance depending upon

anything other than effective

operations tools suffers from GIGO
