The Durgapur-Asansol belt has plants commissioned in the 1960s still operating - alongside 2010s modernisations of the same plants. The drawing-set divergence between commissioned reality and as-operated reality is among the highest we see anywhere in the country. Brownfield as-built reconciliation here is not a service line - it is the first step before any meaningful PSS or risk study can be signed.
Brownfield Digital Engineering is not a service line - it is a posture. Below are the four decision-pillars the Durgapur practice carries.
Plants commissioned in the 1960s have had 50 years of modifications. No drawing-set survives. We LiDAR-capture the plant footprint at 6 mm registered accuracy, reconcile to a defensible engineering reality, and hand that back as the foundation for any subsequent study.
220 kV intake. 11 kV reticulation. 415 V utility. 50-year vintage on the bones, 2010s gear at the modernised bays. We model the full system in ETAP with cross-vintage coordination rules applied.
Eastern chemicals processing facilities are HAZOP-triggered by every modification cycle. We run HAZOP, LOPA, SIL studies under IEC 61511 + IEC 61882 with the OISD overlay where applicable.
Plants in the Raniganj coalfield belt have intermittent fuel supply risk. We run reliability analysis under IEEE 493 with stochastic fuel availability profiles.
A Chartered Engineering practice is defined by the standards it commits to. The Durgapur practice signs against the following codes, with the appropriate industry overlays applied per engagement.

VB Engineering(R) India Pvt. Ltd. operates a single Brownfield Digital Engineering practice. The seven disciplines below are delivered from the Durgapur office with CEng MIE FIE signature from the Hyderabad HQ.
IEEE 1584-2018 Arc Flash incident energy, Load Flow + Short Circuit, Protection Coordination, Transient Stability, Harmonics, Insulation Coordination, Motor Starting, Reliability, DC Arc Flash. ETAP, DigSILENT PowerFactory and PSCAD model build + audit + reconciliation.
Read the practice ->Tripod + drone capture across plant footprint at 6 mm registered accuracy. Pointcloud-to-CAD pipeline. Pre-LiDAR engineering brief and post-capture quality control owned by the practice. Handover-ready for Wistwin where the operator opts in.
Read the practice ->LiDAR-powered productized as-built. P+ID, isometric, GA, equipment layout, process and electrical drawings reconciled to plant reality. Drawing-set restored to a single source of truth. Ready for capex and shutdown planning.
Read the practice ->FlexSim discrete event simulation for manufacturing flow, terminal logistics, mining haulage, healthcare patient flow, airport passenger + baggage flow. Decision-grade animated models that surface the bottleneck before the capex commitment.
Read the practice ->HAZOP, QRA, LOPA, SIL, Bowtie, Consequence modelling. Aligned to IEC 61511, IEC 61882, IEC 60079, OISD-aligned for refining + petrochem scope. Independently reviewed and regulator-ready.
Read the practice ->5-year NFPA 70E recertification retainer. Annual training cycle. Bilingual labelling. PPEAI enforcement layer. Audit-ready handover packs for plant, insurer and regulator review. Recertification windows tracked from the day labels are installed.
Read the practice ->The 5-stage arc flash compliance program. Assess + Label + Train + Enforce + Renew. Delivered across 6 countries. The flagship Brownfield Digital Engineering productized service.
Read the practice ->CEng MIE India practice lead drafts the deliverable against the standards stack. Project file maintained from kick-off.
An independent Principal Reviewer (CEng MIE FIE MIET) who has not been part of the engagement team signs the deliverable. Two-sign discipline. Structural firewall.
Documentation handed back at audit-grade quality - regulator-ready, insurer-ready, capex-committee-ready. Project file archived.
Brownfield engineering on a plant commissioned in 1962 is a different discipline than brownfield engineering on a plant commissioned in 2002. The Durgapur practice is built around the 1960s-vintage reality. LiDAR is non-negotiable. As-built reconciliation is the foundation. PSS and HAZOP studies signed on un-reconciled drawing-sets are not defensible.
Three illustrative engagements with operator names withheld. Technical figures are representative of multiple engagements in the West Bengal regional delivery zone.
LiDAR-captured 4 production halls + 220 kV switchyard. Drawing-set restored to a single source of truth. Full protection coordination re-derived against the reconciled SLD. CEng MIE signature.
Transient stability and harmonics analysis under DigSILENT PowerFactory for a coal-fired unit feeding the eastern transmission corridor. Damping verified bounded. Harmonic filtering recommendation issued.
IEC 61511 + IEC 61882 process safety review across 4 production units. 3 LOPA-derived SIL 2 instrument loops. As-built drawing reconciliation completed in parallel.
A Chartered Engineering practice is defined as much by what it refuses as by what it delivers. These are the four lines we hold.
Scope drives the proposal. Every engagement is scoped per facility and quoted in writing within 5 business days. There is no rate card on this site.
Photographs that appear on engineering pages are real plant work the practice has been part of. We do not synthesise refinery skylines or fictional control rooms to look impressive.
Every drawing, study and report that leaves the practice carries two signatures - the drafting Practice Lead and an independent Principal Reviewer. This is not negotiable.
If the scope changes mid-engagement, we re-scope and re-quote. Hidden scope creep is not how a Chartered Engineering practice operates.
The Durgapur delivery zone covers the following industrial clusters and corridors. Engineering work is scoped per facility - travel to site, plant access discipline and shutdown-window coordination are all part of the engagement.
Tell us the service, the operational decision and the timeline. A practice lead will respond with a written scoping note within one business day.
Each office is tuned to the industrial cluster it serves. Click any city for regional context, technical pillars and selected engagements.
