Gas quantity verification and commercial reconciliation for energy operations.
Accurate gas measurement at fiscal metering points, across transfer interfaces, and through storage, processing, and distribution systems. FUTUREGAZ applies structured measurement and reconciliation methods to reduce ambiguity where commercial and regulatory exposure is highest.
A 0.1% measurement error on a 100,000-tonne LNG cargo can represent millions of dollars in settlement exposure. Measurement uncertainty, calibration status, and calculation methodology are not procedural matters — they determine commercial outcomes.
What this covers
Custody transfer support
Verification of fiscal metering for LNG and natural gas transfers. Covers ultrasonic and Coriolis meter review, tank strapping verification, quantity calculation per GIIGNL Custody Transfer Handbook, and independent check against Ship's Figure and Shore Figure totals.
Boil-off gas (BOG) calculation
Quantification of boil-off gas across storage, laden voyage, and regasification phases. Natural BOG rate calculation, forced vaporisation accounting, reliquefaction credit, and comparison against contractual allowances.
Mass balance reconciliation
End-to-end balance across loading, transport, and discharge. Identifies metering discrepancies, instrument drift, and unaccounted losses. Structured to ISO 6578 LNG measurement procedures and GIIGNL guidelines.
Calorific value and energy calculation
Gross and net calorific value (GCV/NCV) per ISO 6976. Wobbe index calculation for interchangeability assessment. Energy content reporting for gas chromatograph-based quality analysis at custody transfer points.
CNG / LNG truck fuelling verification
Delivered quantity verification and reconciliation for CNG and LNG truck fuelling operations. Covers metering accuracy, dispenser calibration review, delivery records, and commercial settlement checks — including operator programmes such as Shell's LNG truck network.
Loss and operational reconciliation
Identification and quantification of measurement losses across production, transmission, and distribution systems. Structured loss reconciliation aligned to commercial contracts, regulatory requirements, and audit readiness.
Why measurement accuracy matters
Measurement uncertainty has a direct commercial and regulatory cost. At scale, small errors compound into significant exposure.
Custody transfer disputes
Unresolved differences between ship and shore figures, or between buyer and seller metering, lead to invoice disputes, arbitration, and contractual penalties.
Non-traceable metering records
Metering records without documented calibration traceability or methodology fail regulatory audit and cannot support emissions or energy reporting claims.
Unaccounted losses
Without structured mass balance, losses through flaring, venting, instrument leakage, or metering error accumulate undetected — affecting both financial and environmental performance.
Truck fuelling delivery gaps
CNG and LNG dispensing operations without verified metering create delivery shortfalls, contract disputes, and inaccurate carbon reporting against cleaner-fuel claims.
Industries and applications
LNG terminals
Import and export terminals, regasification plants, and floating storage and regasification units (FSRUs). Covers ship-to-shore transfer, tank measurement, and send-out metering.
CNG / LNG truck fuelling
Commercial fuelling stations and private fleet operations using compressed or liquefied natural gas. Delivered quantity checks, dispenser calibration, and reconciliation against bulk supply.
Pipelines and gas infrastructure
Transmission and distribution metering stations, custody transfer points, interconnectors, and network balance measurement for gas grid operations.
Offshore platforms
Production metering, gas lift measurement, flare and fuel gas accounting, and fiscal metering for export pipelines and shuttle tanker loading operations.
Gas distribution
Entry and exit point metering, district metering area balancing, and network loss reconciliation for gas distribution system operators.
