INOVYN — Chemical Plant Shutdown Support
Client: Cj Consulting AB (main contractor) Site: INOVYN chemical facility, Sweden End operator: INOVYN (INEOS Group) Industry: Chemical Plants · Process Industry Period: September 2024 Services: Maintenance & Turnarounds · Pipeline Installation · Equipment Installation · Industrial Welding
Context
INOVYN is part of INEOS — one of Europe’s largest chemical producers. Like all major chemical sites, their facilities run on rolling shutdown programmes, where plant operations are interrupted for inspection, repair, and equipment replacement under strict safety-critical conditions.
Chemical plant shutdowns are among the highest-risk work environments in industrial contracting. Live sites, residual chemical inventory, hot work restrictions, rigorous permit-to-work systems, and the INEOS SHE framework — a company-wide safety management standard that explicitly extends to contractors working on behalf of INEOS.
For MIDAS, this project was the test of two things: our ability to deliver under a specific client SHE regime, and our ability to run welded scope on a chemical site where the consequence of error is materially higher than elsewhere.
Scope
Delivered across the September 2024 shutdown window:
- Replacement of process equipment
- Welding of tie-in piping to existing lines
- Installation of new piping systems in support of replaced equipment
- Full integration into the main contractor’s daily shutdown programme and INEOS SHE requirements
The specifics of what was replaced and where are subject to client confidentiality. What we can speak to is how the work was executed.
Approach
Chemical shutdowns have a different rhythm than refinery turnarounds. The scope tends to be more contained in space but denser in permit overhead. Every weld needs a hot work permit. Every line needs de-isolation verification. Every crew movement is logged.
Our approach:
- Pre-mobilization briefing with Cj Consulting AB on scope, SHE requirements, and integration into INEOS procedures
- Crew induction on the INEOS SHE standard — our welders arrived pre-briefed on the specific safety framework
- Daily integration into the main contractor’s toolbox talks and permit-to-work meetings
- Welded scope execution per WPS, with visual inspection and documentation throughout
- Handover of test pack and weld records to the main contractor at window end
The key delivery was respecting the rhythm of a chemical shutdown — not treating it like any other welding job. Our crew integrated cleanly, produced the required output, and closed out without extending the window.
Outcome
The INOVYN campaign was MIDAS’s first project under the INEOS SHE regime. It established that our welding crews can operate under a major chemical producer’s contractor safety framework and deliver on a short, dense shutdown window. That matters for any future INEOS or comparable chemical-industry work, where SHE integration is not negotiable.
It’s also the basis for our “chemical plant experience” claim elsewhere on the site — a claim we’d never make without a real project behind it.
