What MIQA is
Mechanical integrity is a programme, not a binder
MIQA (Mechanical Integrity and Quality Assurance) is the element of Process Safety Management that ensures equipment containing hazardous energy or hazardous chemicals stays suitable for its intended service throughout its life. The vocabulary comes from OSHA 29 CFR 1910.119(j) and the CCPS guidelines on mechanical integrity systems; the obligation it describes exists in every jurisdiction, including India's Factories Act, MSIHC Rules, IBR and OISD regimes.
Industry loss analyses consistently attribute close to half of large property losses in process plants to mechanical integrity failures: piping that thinned quietly, relief systems that were never tested, repairs made with the wrong material. None of these are exotic failure modes. They are what happens when inspection, testing and quality assurance run on memory instead of a programme.
TCR Advanced delivers MIQA as a service because most Indian plants, and nearly all small and medium scale chemical and petrochemical units, cannot justify an in-house integrity cell. What they can justify is a programme sized to their actual risk, executed by an organisation that has spent 26+ years investigating what happens when integrity fails, backed by NABL accredited laboratories (TC-6739, TC-13053) and NADCAP accredited materials testing (AC7101).

The programme
Six elements of a working MIQA programme
Every element below is a deliverable, not a slogan. Together they are what an auditor means when they ask to see your mechanical integrity programme.
Written procedures
Inspection, testing and maintenance procedures for every covered equipment class, written for the technicians who execute them, controlled the way a 17025 laboratory controls its methods.
Trained people
Personnel trained on the procedures and the hazards of the process. TCR Advanced's Evolve training division qualifies plant teams alongside its own ASNT-qualified inspectors.
Inspection & testing to RAGAGEP
Intervals and techniques set to recognised and generally accepted good engineering practice: API 510 for vessels, API 570 for piping, API 653 for tanks, IBR for boilers, with documented results every time.
API 510 · 570 · 653 · IBR
Deficiency management
Every finding tracked from discovery to close-out. Where a deficiency cannot be corrected immediately, a Fitness for Service assessment per API 579-1 defines the safe operating window until it is.
Quality assurance of new work
New equipment, fabrication, installation and repairs verified against design specification: material certificates, welder qualification, PMI per API RP 578, hydrotest and repair records per ASME PCC-2.

Spare parts and materials QA
Maintenance materials and spares verified as suitable for the service before they go on the shelf, so a stainless line never gets a carbon-steel spool in an emergency at 2 a.m.
Why now
The regulator, the insurer and the asset are all asking the same question
India's process industry is expanding at both ends: world-scale complexes on one side, and thousands of small and medium chemical, petrochemical, agrochemical and pharmaceutical intermediate plants on the other, many of them running equipment well into its second or third decade. The statutory net around them is tightening from every direction: competent-person examinations of pressure plant under the Factories Act and state rules, safety audits and reports under the MSIHC Rules 1989, IBR 1950 for boilers, SMPV(U) Rules 2016 for pressure storage, and OISD standards across oil and gas. Insurers have moved the same way, pricing premiums against demonstrated integrity programmes rather than clean loss histories alone. Multinational customers now audit their Indian suppliers against PSM expectations as a condition of business.
A working MIQA programme answers all of them with one consistent set of records. That is the practical case. The deeper case is the one TCR Advanced has documented across 10,000+ failure investigations: nearly every catastrophic equipment failure we have examined announced itself first, in a thickness reading nobody trended, a relief valve nobody tested, a repair weld nobody inspected. MIQA is the discipline of hearing the announcement.

The service
How a MIQA engagement runs
Sized to the criticality of your equipment, not the size of your company. A single-boiler specialty chemical unit and a full petrochemical complex get the same discipline at different scales.
Walkdown and criticality assessment
Site walkdown, document review and consequence screening produce the MIQA register: which equipment is covered and why.
1
Gap assessment against the six elements
Your current procedures, records, training and QA practices assessed against OSHA 1910.119(j), CCPS guidance and the applicable Indian statutory requirements.
2
Inspection and test plans
Equipment-specific plans to API 510, API 570, API 653, API 576 and IBR, with techniques, locations, acceptance criteria and intervals stated, and RAGAGEP referenced for each.
3
Execution by accredited teams
Field NDT, in-situ metallography, PMI per API RP 578 and laboratory verification delivered by TCR Advanced's own NABL accredited teams (TC-6739, TC-13053). No subcontracted uncertainty.
4
Deficiency close-out and FFS bridge
Findings tracked to closure. Equipment with damage gets a Fitness for Service position per API 579-1 so you know what can safely run and for how long, in writing.
5
Documentation, and the AiOM option
The full programme handed over as audit-ready documentation, or carried live on the AiOM platform with RBI, IOW and RLA working on top of the same records.
6
MIQA is the programme. AiOM is the platform that runs it.
Plants that want the programme on a digital spine carry the same registers, plans and records into AiOM (Asset Integrity Optimization and Management), with Risk Based Inspection, Integrity Operating Windows and Remaining Life Assessment working on top.

Questions plants ask us
MIQA, answered
MIQA stands for Mechanical Integrity and Quality Assurance. It is the element of Process Safety Management, defined in OSHA 29 CFR 1910.119(j) and elaborated in the CCPS guidelines, that keeps process equipment fit for duty throughout its life: written procedures, trained people, inspection and testing at intervals set to recognised and generally accepted good engineering practice (RAGAGEP), correction of deficiencies, and quality assurance from fabrication through spare parts.
Pressure vessels and storage tanks, piping systems including their components and valves, relief and vent systems and devices, emergency shutdown systems, controls including monitoring devices, sensors, alarms and interlocks, and pumps. In Indian plants, IBR-registered boilers and PESO-regulated storage are covered under their statutory regimes within the same programme.
The MIQA vocabulary comes from OSHA's PSM rule, which does not directly apply in India. The obligations behind it do: the Factories Act 1948 and state factory rules require periodic examination of pressure plant by competent persons, the MSIHC Rules 1989 require major accident hazard units to demonstrate safe systems, IBR 1950 governs boilers, PESO and SMPV(U) Rules 2016 govern pressure storage, and OISD standards govern the oil and gas sector. Insurers and multinational customers increasingly audit against PSM expectations regardless of jurisdiction. A MIQA programme is how a plant satisfies all of these with one consistent set of records.
Yes, because the programme is scaled to the criticality of the equipment, not to the size of the company. A typical SME chemical plant engagement starts with a criticality register and a first-year inspection and test plan for the equipment whose failure would actually hurt: reactors, boilers, storage of hazardous chemicals, relief systems. TCR Advanced executes the inspections with its own NDT and laboratory teams, so the plant does not need to hire an integrity department.
MIQA is the programme; AiOM (Asset Integrity Optimization and Management) is the platform that runs it. Plants that start with a standalone MIQA service hold their registers, plans and records in audit-ready documents. Plants that adopt AiOM carry the same MIQA content on a digital spine with Risk Based Inspection, Fitness for Service, Remaining Life Assessment and Integrity Operating Windows working on top of it.
