Annual Shutdown Planning India: Format and 15-Day Plan
An annual shutdown is the yearly planned stop of a plant, and it is planned around statutory items such as renewal of the boiler certificate under the Boilers Act, 2025 and confined space and pressure plant duties under the Factories Act, 1948.
How MaintWiz helps: Annual shutdowns need scope, permits and records ready for inspection. The MaintWiz shutdown module gives plant teams one plan for scope, schedule, permits, spares and execution, from the first work package to close-out. See the module · Get the data sheet

Vocabulary
What do annual shutdown, capital overhaul and statutory shutdown mean in India?
Annual shutdown, capital overhaul and statutory shutdown are plant terms rather than defined legal terms: an annual shutdown is the yearly planned stop, a capital overhaul is a large overhaul of major equipment, and a statutory shutdown is a stop made to carry out a legally required inspection.
Read the five boxes left to right and note that customer supply is arranged before the stop begins, not after it. The two examples show how a plant keeps dispatches going, from stock or from a second plant. Use the same order when you set your own notice date and cover target.
| Step | What happens |
|---|---|
| Notify | Disclose the shutdown to the stock exchanges |
| Build cover | Build finished-goods or clinker inventory |
| Stop and work | Run the planned stop |
| Serve customers | Supply from inventory, or from another plant |
| Restart | Return to production |
| Example: Saurashtra Cement | 24-day kiln shutdown from 21 July 2026; inventory covers dispatches |
| Example: Tatva Chintan | November 2023 annual shutdown; reserve stock plus the Dahej plant for urgent orders |

India: the Occupational Safety, Health and Working Conditions Code, 2020 came into force on 21 November 2025 and subsumes the Factories Act, 1948. The Act sections quoted on this page now have corresponding duties in the Code, and the Centre and the states are still issuing rules under it, so confirm the current rule for your state before you plan work. 5,6
| Term | How it is used | Status |
|---|---|---|
| Annual shutdown | A planned stop of a plant, usually once a year, for maintenance and statutory inspection | Plant usage; no legal definition found |
| Capital overhaul | A large planned overhaul of major equipment such as a boiler or turbine in a power plant | Plant usage |
| Statutory shutdown | A stop made to carry out an inspection or test that a law requires | Plant usage; the requirement itself sits in the law that applies to the equipment |
| Boiler passing | The boiler being inspected and its certificate renewed | Plant slang, not a term in the Boilers Act; see the boiler page |
I searched for authoritative definitions of these terms in Indian law and found none, so the meanings above describe usage. What is legally required is set out for each kind of equipment, as the next section shows. See shutdown vs turnaround vs outage and the types of shutdown guide for how the words are used elsewhere.
Statutory table
What is a statutory shutdown in India?
A statutory shutdown is a shutdown executed to meet a legal inspection or safety duty. For most Indian plants the main duties are the boiler certificate under the Boilers Act, 2025, pressure plant and confined space duties under the Factories Act, 1948, and the state rules that supplement them. 1,3
| Equipment or activity | Law and provision | What it says | Source |
|---|---|---|---|
| Boilers | Boilers Act, 2025, sections 12 and 13 | The certificate authorizes use for no more than twelve months in the main case (twenty-four for a narrow economiser and unfired boiler case); when it ends, the owner applies for renewal and the competent person inspects within fifteen days of the application | Boilers Act 2025 |
| Boilers: in force | Gazette notification of 30 April 2025 | The Central Government appointed 1 May 2025 for the provisions of the Act to come into force | Boilers Act commencement notification |
| Boiler repairs | Boilers Act, 2025, section 10 | Repairs only with, among other conditions, certified welders, a boiler repairer where there are no in-house facilities, approval by a competent person, and safety of persons working inside ensured by the measures the regulations specify | Boilers Act 2025 |
| Pressure plant (factories) | Factories Act, 1948, section 31 | Effective measures must keep pressure plant within its safe working pressure; state rules govern examination and testing and vary by state | Factories Act 1948 |
| Confined spaces | Factories Act, 1948, section 36 | No entry to a confined space where gas, fume, vapor or dust is likely to be present unless a competent person certifies in writing that it is reasonably free, or the person wears breathing apparatus with a rope held outside | Factories Act 1948 |
| Portable lights | Factories Act, 1948, section 36A | Portable electric lights above 24 volts are restricted in such spaces | Factories Act 1948 |
| Hazardous processes | Factories Act, 1948, Chapter IVA (sections 41A to 41H) | A chapter on hazardous processes, with section titles covering disclosure of information by the occupier, the occupier's specific responsibility, emergency standards, permissible exposure limits, workers' participation and the right to warn of imminent danger; the text of these sections was not read for this page | Factories Act 1948 |
Software
How can software help with an annual shutdown in India?
Software can hold the job list with its statutory basis, the certificate dates and the schedule together, so mandatory jobs are visible and protected when the scope is trimmed.
Also see boiler shutdown in India.
What the shutdown module covers
- Preventive maintenance scheduling shared with the shutdown module, so certificate and inspection dates are visible before the freeze
- Gantt chart with the critical path and float
- Work packages with owner, crew, dates and permits
- Permits and isolations from ePTW on each work order
- Import and export with Excel and Microsoft Project XML, with interoperability with Primavera P6
- Reports and tables behind the charts export to Excel

Job list
What should an annual shutdown job list format contain?
An annual shutdown job list should have nine columns: ID and tag, description, source of the job, statutory basis, trade and hours, duration and predecessors, permit and isolation, materials and tools, and status with an owner.
A free Excel file for this page: India annual shutdown format and boiler checklist (.xlsx).
| Column | What to enter | Why |
|---|---|---|
| ID and equipment tag | Unique job ID and the tag of the equipment | Links the job to asset history |
| Job description | What will be done, in one line | Reviewable scope |
| Source of job | Statutory, preventive, breakdown carry-over, modification, opportunity | Separates mandatory from optional work |
| Statutory basis | The law or inspection that requires it, if any | Protects statutory jobs from being cut |
| Trade, crew and hours | Craft, headcount, estimated hours | Feeds resource loading |
| Duration and predecessors | Days and the jobs that must finish first | Builds the critical path |
| Permit and isolation | Permit types and isolation points | Safety planning |
| Materials and tools | Parts, with stock or order status, and special tools | Readiness |
| Status and owner | Open, ready, in progress, done; named owner | Daily control |
Freeze the list at a set date and control additions. See shutdown scope management and the work package guide.
Worked plan
How do you plan a 15-day annual shutdown?
Plan a 15-day annual shutdown of a chemical or process plant backward from the restart date: the chain of inspection, repair and reinstatement sets the critical path, utilities and the rest of the plant fit around it, and statutory inspections are fixed hold points. 4
For sugar mills see sugar mill off-season maintenance; for chemical plants see chemical plant shutdowns.
| Days | Process units | Utilities and the rest of the plant | Control point |
|---|---|---|---|
| 1 to 2 | Stop feed, de-inventory, cool, flush and purge | Stock cover confirmed; utilities isolated section by section | Lockout and isolation verified |
| 2 to 3 | Blind and isolate; gas-free tests | Contractors mobilise; scaffolding and cranes ready | Confined space entry permits issued |
| 3 | Open columns, reactors, vessels and exchangers | Storage tank and effluent plant jobs start in parallel | Gas-free certificate before entry |
| 4 to 5 | Inspect vessels, columns, exchangers and piping; thickness readings | Pump, compressor and agitator overhauls start; relief valves out for testing | Findings logged by a competent person |
| 6 to 10 | Repairs, exchanger bundle cleaning, catalyst change-out, lining repair | Electrical, instrument and calibration jobs in parallel; relief valves tested and refitted | Repairs approved; welders certified |
| 11 to 12 | Close up; remove blinds in the planned order | Rotating equipment aligned; loops checked | Blind list reconciled; foreign-object check |
| 13 | Leak and tightness test; nitrogen purge | Utilities lined up; control system checks | Pre-startup safety review |
| 14 to 15 | Light-off and line-out | Quality release; packing and dispatch restart | Start-up authorised |
The plan illustrates how a chemical plant's annual stop is sequenced. Duration varies by plant, so use your own history as the benchmark. For the critical path calculation see critical path and float; for a boiler-led stop see boiler shutdown in India.
Confined space
What does the Factories Act require for confined space entry?
Section 36 of the Factories Act, 1948 bars entry to a confined space where gas, fume, vapor or dust is likely to be present unless a competent person certifies in writing that it is reasonably free of them, or the entrant wears breathing apparatus with a rope held outside. 3
Section 36A restricts portable electric lights above 24 volts in such spaces. 3 State factory rules vary and add detail such as permit forms; use your site's entry permit system. See permit to work during a shutdown.
Boiler certificate
What does the Boilers Act, 2025 require for the boiler certificate?
Under sections 12 and 13 of the Boilers Act, 2025, the boiler certificate authorizes use for no more than twelve months in the main case (twenty-four for a narrow economiser and unfired boiler case); when it ends, the owner applies for renewal and a competent person inspects within fifteen days of the application. 1
Section 10 allows boiler repairs only on conditions that include certified welders and approval by a competent person. 1 The Central Government appointed 1 May 2025 for the Act to come into force. 2 Plan the inspection, repairs and renewal into the shutdown schedule; see boiler shutdown in India for the boiler-led plan.
