Request shutdown planning supportHow the calculation works
The planner contains 8 editable shutdown tasks (lockout, cleaning, dismantling, inspection, repair, reassembly, idle test, start-up and handover). Each task has a duration in hours, a track (1–3, representing parallel crews) and a team size. The critical path is the longest track total; labour cost = duration × team × hourly rate; downtime cost = critical path × downtime cost per hour.
Example: with all 8 tasks on one track, the shutdown lasts 36 hours. Moving one 4-hour task to a second track shortens it to 32 hours.
Frequently asked questions
What is the critical path?
The longest sequential chain of tasks, which determines the total length of the shutdown.
How can I shorten a shutdown?
Split tasks onto parallel tracks, prepare materials and spare parts in advance, and lock out the machine early.
Does the calculation include contingencies?
No, it is a baseline plan. Add a time buffer according to the age of the machine and the risk of the work.

Methodology and limitations
Methodology based on standard industry calculations and Maintest’s practical industrial experience. This tool provides a planning estimate and does not replace project-specific engineering assessment. This tool is a screening and planning aid developed by Maintest. Results are indicative and depend entirely on the figures and answers you enter. They are not an engineering calculation, a safety assessment or a substitute for the manufacturer’s instructions, applicable standards or professional judgement. Weights, benchmarks and default values are Maintest planning assumptions and can be adjusted to your situation. Do not use this tool as the only basis for safety-critical decisions such as lifting, electrical work or lockout procedures.
