Asian Refiners Eye Inspection Overhaul as India Demand Growth Lifts Turnaround Stakes
New analysis argues risk-based inspection could halve turnaround scope at Asian refineries, with India's demand trajectory raising the cost of extended outages.
Risk-based inspection programmes can cut refinery turnaround scope by as much as 50%, according to analysis published Monday (2026-08-31) on Asian Power, which linked the methodology to growing operational complexity across Asian energy infrastructure.4
The claim carries particular weight for Indian refining. Nayara Energy's 2026 scheduled turnaround at its Vadinar complex in Gujarat, India's second-largest single-site refinery, drew in more than 34,000 personnel and around 480 pieces of heavy equipment, including 180 cranes, according to the company. Turnarounds at that scale are expensive, logistically demanding, and carry real supply risk for downstream fuel networks.1,2
Nayara said it completed the maintenance and upgrade programme without disrupting fuel supplies across its distribution network. The Vadinar case illustrates the scale of what is at stake. At a facility of that size, a 50% reduction in scope, if realisable, would represent a meaningful compression of downtime, contractor costs and the organisational burden of mobilising tens of thousands of workers.1
Risk-based inspection shifts the logic of plant maintenance from calendar-driven checks to data-led prioritisation, directing engineering resources toward components with the highest demonstrated integrity risk rather than applying uniform schedules across all assets. The Monday (2026-08-31) analysis argued the approach allows operators to combine inspection findings with field observations to build a dynamic picture of asset condition over time.4
The same report referenced the Tengiz field in Kazakhstan as one of the operating environments where such methodologies face greatest pressure. A complex sour gas processing site holding approximately 26 billion barrels of oil and gas reserves, Tengiz ranks among the world's most technically demanding upstream facilities and points to the kind of assets where inspection scope decisions carry the heaviest consequences.4
India's refining sector faces growing demand pressure regardless of inspection methodology. The Monday (2026-08-31) Asian Power piece flagged India's oil demand trajectory as a structural driver alongside Indonesia's production ambitions, which the report pegged at potentially reaching 1 million barrels a day by 2030. ICE Brent crude front-month was at $90.88 a barrel as of 2026-08-31 12:49 UTC.4
Asia's energy infrastructure investment story extends beyond hydrocarbons. The region accounted for 74.2% of global renewable capacity additions in 2025, adding 513.3 gigawatts to bring total installed capacity to 2,891 gigawatts, or 56.1% of the global total, according to WTW's Renewable Energy Market Review 2026. That scale of build-out creates its own inspection and asset-integrity demands, particularly as offshore and remote infrastructure increasingly replaces conventional crewing arrangements.3
The practical gap between the 50% scope-reduction claim and what operators achieve in the field remains unquantified. Nayara's Vadinar turnaround was conducted under a conventional schedule, and the company has not disclosed what share of work was driven by risk-prioritised inspection versus fixed maintenance intervals. For Indian refiners managing ageing assets against rising domestic demand, the next major turnaround cycle will test whether the methodology's ambitions survive contact with plant-level execution.1,4
