For brownfield Sinopec integrated refining-petrochem complexes in China: throughput modelling, bottleneck analysis, utilisation forecasting, and what-if scenario evaluation, all on validated DES models with documented input data and confidence intervals.
Across the Sinopec and CNPC integrated refining-petrochem complexes, the Yangtze River Delta chemicals corridor, and the Guangdong EV-battery processing cluster, a validated discrete-event simulation is what turns a capex proposal from an argument into evidence. China is the world's largest industrial electrical engineering market by volume but the work shape is unusual: most facilities are recent (2005-2020 vintage) and operate under the GB / GB/T national standards, which interoperate with IEC. The brownfield retrofit opportunity is concentrated in the petrochemical complexes (Sinopec · CNPC · CNOOC), state-owned power generation, and the EV-battery and rare-earth processing build-out. China's industrial estate is younger than the West's but rapidly accumulating brownfield retrofit demand. The state-owned operators are running multi-year safety-improvement programmes that require comprehensive electrical-system re-baselining. Multinational JVs accelerate this by requiring international-standard documentation alongside the GB-compliant package.
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 GB 50054 (Code for design of low-voltage distribution) · GB 50217 (cable selection) · GB 50058 (hazardous-area · IEC-aligned) · GB/T 50063 (electrical instruments), the engineering reference layer aligns; the simulation methodology is invariant.
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 China 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.
Three China engagements (a Sinopec refining-petrochem complex, a Xinjiang upstream gas-gathering field, and a Guangdong gigafactory) that illustrate the working pattern:
an integrated 12 MTPA refining-petrochem complex with 110 kV intake and 10 kV distribution.
The engagement: Multinational JV demanded IEEE 1584-2018 arc flash baseline alongside the GB-compliant electrical-safety regime; bilingual Mandarin-English deliverable.
a gas-gathering field with 35 kV ring main and dozens of wellhead substations.
The engagement: Field-wide coordination drift over the network expansion; mass relay setting reset + arc flash recalculation + bilingual labels.
a 50 GWh battery cell manufacturing plant with 110 kV intake and 10 kV distribution.
The engagement: First-of-kind plant arc flash baseline against international standards; DC arc flash methodology for battery formation lines integrated with AC distribution.
