25 marquee operators across 21 countries trust VB Engineering with their Discrete Event Simulation engagements.
VB Engineering Discrete Event Simulation from the London channel partnership. Country-native standards overlay. CEng UK (EngC) + IET MIET 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 UK operator can act on.
Across the Humber refining cluster, the Grangemouth petrochem complex, the Manchester-Slough data-center belt, and the Teesside chemicals corridor, a validated discrete-event simulation is what turns a capex proposal from an argument into evidence. The UK industrial electrical engineering market combines an aging but extensive refining and chemicals base (Grangemouth · Stanlow · Pembroke · Humber), the North Sea offshore decommissioning and electrification pivot, a fast-growing data-center build-out across London and Manchester, and a brownfield-only manufacturing base in the Midlands and Northeast. HSE enforcement under the Electricity at Work Regulations 1989 is the regulatory backbone. The UK's industrial estate is largely 30-50 years old. There is essentially no greenfield refining or chemicals capacity coming on. The growth is data centers, EV manufacturing, and decommissioning the offshore base · and all three are brownfield engineering, often on heritage industrial land.
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 BS 7671 (IET Wiring Regulations · 18th edition) · BS EN 60909 (short-circuit) · BS EN 61936 (HV) · BS EN 60079 (hazardous area) · BS EN ISO 14001 (environment), the engineering reference layer aligns; the simulation methodology is invariant.
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.
Where input data has measurement uncertainty (a recurring reality in UK 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.
Three UK engagements (a Humber refinery, a West-London hyperscale data center, and a Teesside chemicals plant) that show the pattern:
a 200,000 BPD refinery with 132 kV intake and 1970s-vintage 6.6 kV switchgear.
The engagement: HSE Improvement Notice on arc flash hazard control; full plant IEEE 1584-2018 baseline + BS 7671 conformance retrofit + DSEAR alignment.
a 40 MW Tier-III colocation with N+1 paralleled UPS and 33 kV utility intake.
The engagement: Insurer-driven arc flash baseline before policy renewal; harmonic measurement + protection coordination + IEEE 1584 study against BS 7671.
an organic chemicals plant with Zone 1 hazardous-area bays and 11 kV distribution.
The engagement: DSEAR Risk Assessment renewal demanded reconciliation between the hazardous-area dossier and the as-installed equipment; LiDAR walk-through + Zone-by-Zone update.
Buyer questions we hear consistently across HSE Improvement Notice, DSEAR Risk Assessment, and BS 7671 conformance conversations:
