25 marquee operators across 21 countries trust VB Engineering with their Discrete Event Simulation engagements.
VB Engineering Discrete Event Simulation from the Doha operations entity. Country-native standards overlay. UPDA-licensed + CEng MIE signed. Native handover to Wistwin · the sister Industry 4.0 digital twin SaaS.
When the question is "what does this plant do under conditions A versus conditions B," discrete-event simulation gives a defensible answer. We build the models, run the experiments, and deliver evidence-grade analysis the Qatar operator can act on.
Across the QatarEnergy LNG mega-trains at Ras Laffan, the Mesaieed industrial base, and the North Field Expansion build-out, a validated discrete-event simulation is what turns a capex proposal from an argument into evidence. Qatar's industrial spine is QatarEnergy's LNG and gas-processing complex at Ras Laffan and Mesaieed, plus the petrochemical platforms (QChem · Qatofin · QAPCO). The North Field Expansion (NFE / NFS) is adding 49 MTPA of LNG capacity between 2026 and 2027, making the country the densest concentration of new LNG capacity globally. Ras Laffan is unique in the LNG world: a single mega-cluster operated by a single integrated owner. The brownfield engineering opportunity here is enormous because NFE adds capacity adjacent to the existing trains, and the existing trains all need re-baselining as the surrounding electrical environment changes.
Process is captured to BPMN 2.0 and ISA-95 conventions. Input data validated to ASTM E2476 / VV&A practice. Output statistics confidence-bounded; no single-run results in the deliverable. Where the operator references QatarEnergy Engineering Specifications (QGS / QP-STD) · IEC 60909 · IEC 61936 · IEC 60079 · IEEE 1584, the engineering reference layer aligns; the simulation methodology is invariant.
Where input data has measurement uncertainty (a recurring reality in Qatar brownfield plants), the deliverable includes sensitivity sweeps on the top input drivers so the operator sees which assumptions move the answer the most.
The FlexSim / AnyLogic / Simio model handed over with a run-book the operator's engineering team can use to run their own experiments. Where the operator subscribes to the Wistwin platform, the model integrates with the digital-twin layer directly.
Process flow captured on the live plant, walked with operations, modelled in FlexSim / AnyLogic / Simio. As-Is model validated against 4-6 weeks of historian data so the baseline matches reality before any what-if begins.
Steady-state throughput under base-case conditions, with bottleneck identification at the resource level. Where the bottleneck is constraint-stacked (two resources alternating as the constraint), the model surfaces this with utilisation curves rather than averages.
Capex options modelled side-by-side (debottleneck option A versus capacity-expansion option B versus operational-change option C). Each scenario reports throughput, utilisation, queue length, and Service Level confidence with bounds.
Random-failure modelling of the critical equipment fleet with MTBF / MTTR from the operator CMMS. Plant performance under cascading failure scenarios. The deliverable answers "how resilient is this plant" with a defensible number.
Three Qatar engagements (across QatarEnergy LNG, Mesaieed petrochem, and Qatalum) that show the pattern:
a 7.8 MTPA LNG train with 132 kV intake and electric-drive main refrigeration compressor.
The engagement: NFE adjacency demanded short-circuit reassessment of the existing trains; harmonic load flow + new MV switchgear coordination integrated with QatarEnergy AMS.
a polyolefins complex with 66 kV intake and 11 kV distribution.
The engagement: Insulation coordination after Kahramaa upgraded the 66 kV feeder switchgear; SPD selection + ground-grid reconciliation.
an aluminium smelter with 220 kV intake and pot-line rectiformer banks.
The engagement: Pot-line harmonic management at the PCC; tuned filter design + harmonic measurement campaign + QGS-format report.
