Why Kolkata generates VT demand
Kolkata anchors eastern India's industrial corridor: IOCL's Haldia refinery and the petrochemical complex beside it downriver, Garden Reach's warship building, the Kolkata and Haldia port systems, and the Durgapur–Burnpur steel belt inland — an old industrial base whose ageing plant needs more examination, not less.
Every refinery inspection starts visual: external corrosion under insulation evidence, support and foundation condition, and internal vessel entry examinations that decide what the rest of the scope becomes.
Every class survey is anchored in visual examination — structure, coatings in ballast tanks, and the close-up surveys that scaffolding and rafting exist to enable.
Refractory, shell and structural condition assessment across furnaces and casters is visual work under severe access constraints.
Boiler internal inspections, casing and duct condition, and remote visual work in headers and drums set the volumetric scope for every outage.
What typically gets examined
In practice that means VT work across refinery and petrochemical equipment at Haldia, warship and commercial hulls at Garden Reach, port infrastructure and cargo gear, blast furnaces and mills in the steel belt, and legacy thermal power plant — with scope set by the damage mechanisms each asset actually runs, not by a standard menu.
Certification and acceptance in Kolkata
IBR governs the boiler stock, classification societies and naval rules the shipbuilding, and IOCL and SAIL their own agency approvals; personnel certification is ISNT (NCB) — whose national office sits in Kolkata — or ASNT where contracts import it.
Examinations themselves are performed to ASME Section V Article 9, AWS D1.1 visual acceptance for structural welds, and API 510, 570 and 653 in-service visual requirements. The evidence chain — technician certification current on the day, instrument and reference block calibration, and the procedure revision in force — travels with every report, because that bundle is what an audit actually checks.
Working with Atlantis in Kolkata
Atlantis delivers visual testing through inspection teams mobilised to site, working under Atlantis procedures with ASNT Level III oversight — we are straightforward that this is a mobilised model rather than a walk-in local office, because for planned inspection work that is usually the better arrangement anyway: the crew, procedures and equipment arrive matched to your scope. Read the VT service overview, see how results are recorded and retrieved, or tell us about the Kolkata scope and we will respond with an honest view on mobilisation.
