BG GROUPCoatings Consultant
For over 21 years, Gaurav Changawala has stood between steel and corrosion — safeguarding reactors, columns, coke drums and heat exchangers on the world's most demanding Oil & Gas, refinery and petrochemical projects. Seven promotions at L&T Heavy Engineering. Today, as Founder of BG Group of Paint & Coating Consultant, he brings that mastery to clients across the globe.
Two stories, one page — the making of an industry expert, and the rise of the consultancy he now leads.
Like a great coating system, a great career is applied one deliberate layer at a time — surface prepared, each coat inspected, nothing left to chance. This is the story of how a campus-selected Diploma Engineer from Surat became one of India's most trusted names in industrial surface treatment.
“With over twenty years of surface treatment and corrosion experience, I want to apply my skills and knowledge of effective surface treatment to lead my team and exceed every goal — developing my leadership while supporting my people with everything I know about coating trends.”
Campus-selected into Larsen & Toubro Heavy Engineering, Hazira, as a Diploma Engineer Trainee — starting on the fabrication shop floor, supervising shifts on HDS reactors for Fluor and EO reactors for KBR.
Moving into coating, heat treatment and scaffolding, he turns theory into instinct — hands-on with epoxies, zinc, PU and MIO, managing 90+ workmen while learning that in pressure vessels, "good enough" does not exist.
BGAS-CSWIP Painting Inspector Grade 2, NACE CIP Level I, then NACE CIP Level II (No. 20438) — joining a select global community of certified inspectors, while introducing Thermal Spray Aluminium at L&T Hazira.
As Head of Surface Treatment & Coating, he owns the lifecycle end to end — estimation, procedures, planning, execution, inspection — delivering ~140 equipment a year and mentoring the team beneath him.
Fireproofing introduced to Heavy Engineering. FRP linings for Hassiyan, Dubai. Peel-off preservation coatings. Water-based ceramic coating. Benchmark records in acid cleaning. The ITER nuclear fusion project's pickling and ultrasonic cleaning of 60,000+ components.
Russia (2014 & 2016) to rescue erected VCC reactors for TOYO/TAIF-NK. Malaysia (2018) for KBR/LOTTE's K-COT converter. Dubai (2020) for GE's Hassiyan water-box lining. Every trip, a coating problem solved on foreign soil.
As Coating Technical Expert leading ~200 equipment a year and 400 contract workmen, he builds online surface treatment systems, quality modules, dashboards — and pioneers AI-assisted coating estimation delivering 90% right-first-time inputs.
After 18+ years at L&T, he founds BG Group of Paint & Coating Consultant — NACE inspection, client representation and consulting for Technip Energies, Praj, Afcons, Zeeco, Heatex and more, on projects from INEOS to BP NZT UK and LNG Canada.
A Post Graduate Program in Corrosion Management & Technology from IIT Ropar caps two decades of practice with formal mastery — and sets the stage for the next chapter: digitising the coating industry itself.
How education, certification and experience compounded into leadership — and then into enterprise.
From campus trainee to Coating Technical Expert to founder — every step certified, inspected and delivered.

The story begins in Surat ? 85.29% in SSC (2000) and HSC from St. Xavier?s (2002): a strong science foundation and the curiosity about how things are made that would define a career.
End-to-end command of the surface treatment and protective coating value chain — from the first blast to the final sign-off. The cross-section on the right is more than a diagram: it is the philosophy. Every layer matters. Every micron is measured. Every system is engineered for the environment it must survive.

Across three business units — Refinery & Petrochemical, Heat Transfer, and Nuclear — he owned every link of the surface treatment chain. This is what that actually means.
Study the tender and every governing specification; raise technical queries at the earliest stage; work out the coating system from spec, operating parameters, preservation and transportation needs; cost each system per sq.m of raw material and labour — including acid cleaning — and carry the cost break-up and feasibility for every single equipment to management approval.
Work with Design and project teams on vessel parameters; take paint-manufacturer inputs on systems and performance; embed every testing parameter into the procedure; walk the client through procedure and ITP in pre-job and pre-inspection meetings; record and close every MOM point alongside document approval.
Six-month advance departmental planning across RPV, HTE and Nuclear BUs; convert project lists into sq.m and order paint and abrasive; secure dehumidified sheds, blasting slots and priorities; and take extra care with the special processes — fireproofing, TSA/Zn, FRP, shot peening, glass flake lining, and acid or ultrasonic cleaning.
Get the work done through subcontractors while coordinating TPIs and clients — LRIS, BV, EIL, DNV; enforce British, SSPC, NACE and ISO standards; run every abrasive from shot and garnet to glass beads, and every system from inorganic zinc silicate to solvent-free epoxies by International, Jotun, Carboline, PPG, Hempel and Sherwin-Williams; monitor weather before and during application; execute pickling & passivation; own permits, protocols and timely handover.
Post-2018, structured data runs the department: online surface-treatment requests with finance and quantity approvals, quality modules quantifying contractor rejection rates, scaffolding dashboards, and a live vendor-rating system. AI estimation reached 90% right-first-time inputs, with non-contact DFT gauges, motion-sensor deadman switches and laser cleaning in the pipeline. And when responsibility itself changed — centralising purchase, subcontracting and stores in 2014, restructuring into Technical, Execution and Payment verticals in 2019 — he led the change rather than resisting it.
Brought Thermal Spray Aluminium to Heavy Engineering, then scaled it — 22+ refinery equipment for KNPC, robust process control proven on LNG Canada and IOCL Bathinda, and applicator qualification for ExxonMobil USA.
Established passive fire protection capability in Heavy Engineering and completed 10 projects for ExxonMobil and Worley — a brand-new product line built from procedures up.
Implemented peelable preservation coatings for SS and blasted-TSA surfaces, first-ever water-based ceramic coating for gasification projects, and glass-bead blasting as a pickling alternative.
Built online surface-treatment, inspection-quality and scaffolding modules with live dashboards, vendor-rating analytics — and AI-based coating estimation reaching 90% right-first-time inputs.
Process lead for pickling & passivation of the ITER Vacuum Vessel and ultrasonic cleaning of 60,000+ In-Wall Shield components through an 8-stage process — nuclear-fusion-grade cleanliness.
Set company benchmark records: acid cleaning scaled from 84 to 446 sq.m per shift, 94 sq.m/shift blasting & painting, 35,000 psi ultra-high-pressure water jet cleaning, and EO reactor tube ID blasting with PLC control.

"Corrosion never sleeps — so quality can never rest. Every micron of a coating is a promise made to the people who depend on that asset. My job is to keep that promise."
To extend the life of critical industrial assets through uncompromising coating quality, deep technical knowledge and honest, independent advice.
A coating industry where every procedure is digital, every inspection is transparent, and every asset owner gets the protection they paid for.
Integrity in inspection. Precision in execution. Generosity in sharing knowledge. Respect for every person on the shop floor — the cultural transformation he led at L&T began with exactly this.
This portfolio tells two intertwined stories. One is a man’s journey from trainee to industry expert. The other is what he built with it — a coating consultancy that pairs deep refinery expertise with a genuinely modern digital presence, and that clients now describe, in their own words, as honest, expert and reliably “On Time In Full.”
After 18+ years protecting the world’s most demanding pressure vessels at L&T Heavy Engineering, Gaurav Changawala saw the same gaps repeat across the industry: coating knowledge locked inside a few experts, procedures reinvented on every project, and quality decided too late. BG Group was founded to close those gaps — putting an independent, certified expert on the client’s side of the table.
Empowering businesses with innovative solutions and revolutionising industries through expertise in surface treatment, refinery equipment care, certifications and customised coatings — with excellence, efficiency and customer-centricity driving success in a digital era.
