SIMOPS Planner
Plan Simultaneous Operations: build a matrix of permitted operations (MOPO) marking every activity pair Go / Restricted / Prohibited, list planned activities with time windows, and flag clashes before they happen. Seed it from an oil & gas, construction, marine or aviation template. Saved on your device; export CSV, PNG or JSON.
Open SIMOPS Planner →What is the SIMOPS Planner?
A free tool for planning Simultaneous Operations (SIMOPS) — where two or more activities run at the same site and time, such as a drilling rig working next to a live production or pumping station. Build a Matrix of Permitted Operations (MOPO) that marks every pair of activities as Go, Restricted or Prohibited with the controls each restricted pair needs, then list the activities you have planned with their time windows so the tool can flag any clash before it happens. Seed it from a built-in oil & gas, construction, marine or aviation template, or start blank. Everything is saved on your device and runs offline. It is a planning aid, not a live monitoring or permit-approval system.
How to use SIMOPS Planner
- Pick a template — Choose an industry template to pre-fill the activity list and default compatibility rules, or select Blank / custom to build your own.
- Set up the operation — Enter the operation name, location, SIMOPS controller (the single point of accountability) and date so the exported plan is properly headed.
- Tune the MOPO matrix — Click any cell to cycle the two activities between Go, Restricted and Prohibited. Add or remove activities to match your site.
- Add the required controls — For each Restricted or Prohibited pair, write the controls or mitigation needed — for example continuous gas monitoring or a dedicated fire watch.
- List planned activities — Add each planned activity with its type, area, start and end time. When two overlap in time and their types are Restricted or Prohibited, the Clash check flags them with the required control.
- Export — Use the Download menu to save the plan as CSV, a PNG image, or a re-importable JSON file you can reopen or share.
Frequently asked questions
What is a MOPO?
A Matrix of Permitted Operations. It cross-references every pair of concurrent activities and states whether they can run together (Go), only with controls (Restricted), or never (Prohibited). It is the core control document for any SIMOPS.
How does the clash check work?
It compares the start and end times of your planned activities. When two overlap in time and their activity types are marked Restricted or Prohibited in the matrix, it raises a clash and shows the required control, so conflicts are visible before work starts.
Can I use it for industries other than oil and gas?
Yes. The engine is generic and ships with oil & gas, construction, marine and aviation templates plus a blank one. You can rename, add or remove activities and rewrite every rule, so it fits any SIMOPS.
Is my data uploaded anywhere?
No. Everything is worked out and saved entirely in your browser, and stays on your device between visits. Export a JSON file if you want a backup or to share the plan.
Does it replace a permit-to-work or live monitoring system?
No. It is an offline planning aid for building the matrix and spotting clashes early. It does not approve permits, track live status or read sensors — those belong to your site's control-of-work systems.
Tips
- Name a SIMOPS controller (single point of accountability) in the setup so the exported plan shows who can stop either operation.
- Give every planned activity a start and end time — the clash check only fires on activities that overlap in time.
- Write real, specific controls on each restricted pair (gas monitoring, fire watch, exclusion zone) so the clash cards are actionable, not just a colour.
- Export the JSON to back up or hand over a plan, and the PNG or CSV for the SIMOPS pack and the daily coordination meeting.
