What is shutdown management software?
Shutdown management software digitalises the entire shutdown lifecycle through a structured management operating system. It brings processes, responsibilities and information together, creating a central foundation for storing shutdown data, managing performance and driving continuous improvement.
What is SMSi?
SMSi is shutdown management software built for mining and heavy industry. It connects shutdown strategy through a major event calendar with readiness, field execution and post-shutdown improvement in one system, so leaders can see risk early, protect plant availability and reduce shutdown overruns.
What are the benefits of SMSi?
SMSi standardises how shutdowns are planned, prepared, executed and reviewed, helping teams apply proven practices consistently across events and sites. It brings shutdown data, progress and decisions into one place, gives corporate leaders clearer oversight and governance, and makes risks visible early enough to act. This helps teams reduce overruns, protect plant availability and improve each successive shutdown.
Who benefits from SMSi?
Shutdown managers, planners and schedulers can coordinate events and track readiness. Supervisors can report progress directly from the field. Maintenance and operations leaders can see emerging risks and make timely decisions, while executives can compare shutdown performance across events and sites.
What is Overall Shutdown Effectiveness (OSE)?
Overall Shutdown Effectiveness is the SMSi measure of how well a shutdown performed against its plan. It brings readiness, schedule, budget and scope performance into a single post-event score, giving executives one comparable number across events and sites. One global industrial minerals client lifted OSE from 61% to 97% over three years.
What return on investment can we expect?
Return depends on your shutdown frequency, event costs and current performance. Even a modest reduction in overrun hours can have significant value where lost production is costly. The SMSi shutdown ROI calculator estimates payback for your own operation using your shutdown data and operating assumptions.
How is SMSi implemented at a fixed plant?
We start by understanding your shutdown process, event calendar, team roles and reporting needs. We then configure SMSi for your plant, bring in the relevant event data, train users and support the team through its first events. The rollout is scoped around your existing ways of working and the size of your shutdown portfolio.
Does SMSi work offline on a mine site?
Yes. Supervisors can use the Supervision Plus mobile app to record work progress, delays and field evidence without a connection. Their updates synchronise when the device reconnects.
Who is behind SMSi?
SMSi is developed by IMMS, an Australian company based in East Brisbane, Queensland, with an active team operating out of Perth, Western Australia. Built by people with hands-on shutdown and asset management experience, SMSi reflects the practical needs of fixed plant teams and won the 2026 Queensland iAward in the Business and Industry category.
