Maintenance & Turnarounds

What this service is

Mechanical, welding, and piping support during scheduled and emergency plant shutdowns. We work under your turnaround structure — plugging into existing daily briefings, permit-to-work systems, inspection regimes, and outage schedules — without asking the turnaround manager to rebuild their process around us.

This is what we’re built for. Our portfolio is heavy on turnaround work because it’s the mode Nordic main contractors deploy us in most often: tight window, clear scope, documented handover, move on to the next site.

Scope

Typical turnaround scope we execute:

• Piping removal, replacement, and tie-in welding
• Pressure equipment repair — drums, columns, heat exchangers, reactors
• Furnace tube work (where access permits)
• PSV line modification and replacement
• Blowdown line work
• Feedwater and steam system repair
• Line flushing, cleaning, pressure testing
• Equipment installation and tie-in (new units into operating lines)
• On-the-clock weld repair of identified defects

Scope we do not run alone (coordinated):

• Mechanical equipment disassembly and reassembly (typically the plant’s mechanical contractor)
• Electrical and instrumentation isolation/reinstatement (plant E&I)
• Insulation removal and re-application (insulation contractor)
• Plant operations isolation and de-isolation (plant ops)
• Final commissioning and start-up (plant commissioning team)

We focus on what we’re best at — welded mechanical work — and integrate cleanly with the rest.

How we integrate into your turnaround

1. Pre-mobilization briefing — we receive scope, drawings, isometrics, WPS package, and HSE induction material 2–4 weeks before the outage start
2. Welder-to-scope matching — our welding coordination maps qualified welders to each line class and submits the matrix for client review
3. Mobilization — crew arrives on or before outage start, pre-inducted on plant-specific HSE
4. Daily integration — we attend daily turnaround meetings, submit daily progress, attend permit-to-work briefings
5. Continuous QC — welds documented as they’re produced, not after the fact
6. Handover — test pack, weld map, traceability delivered on outage end, ready for client commissioning

Our crews are set up to match Nordic turnaround rhythm — early morning starts, structured daily safety briefings, permit-based work, logged interventions. We don’t have to be trained in any of that when we arrive.

Codes and standards

• ISO 3834-2 — Welding quality framework across all weld scope
• EN 13480 — Metallic industrial piping for repair and replacement
• ISO 45001 — Safety management system framework
• PED 2014/68/EU — Pressure equipment where applicable
• ASME B31.1 / ASME B31.3 — Where plant operates to ASME codes
• Plant-specific specs — we adopt your WPS library, your WPQRs, your inspection and test plan

HSE integration

Turnaround work happens on live sites with live risks. Our HSE approach aligns to ISO 45001 and integrates with client systems:

• Permit-to-work — we work under plant PTW. Our supervisors are certified or inducted to plant PTW requirements before deployment.
• Hot work permits — issued per plant procedure, with fire watch, extinguisher, and exclusion zone per spec
• Confined space entry — trained crews for vessel entry, with atmospheric monitoring and standby personnel
• Working at height — certified for the national standard of the country we operate in
• Client HSE codes — we adopt and brief crews on client-specific codes such as INEOS SHE (for INOVYN projects) or plant-specific codes at St1 and other sites

For detail see our HSEQ page.

Why main contractors bring us onto turnarounds

Three reasons, from what our partners tell us:

1. We don’t need management. A main contractor running a turnaround doesn’t have spare capacity to micromanage a subcontractor. We arrive with our own welding supervision, documentation discipline, and integration habit.
2. We deliver on sequential windows. Our three consecutive St1 campaigns are the proof — we don’t disappear between shutdowns. If you have the next window scheduled, we can be on it.
3. Our welders are qualified, not improvised. Every welder deployed to a turnaround has a valid EN ISO 9606-1 qualification matched to the WPS for the specific scope. No substitutions mid-job.

Frequently asked

What’s the shortest outage window you’ve worked on? Two weeks. On short windows we maximize welder-to-supervisor ratio and bring pre-qualified welders only, so zero time is lost to qualification testing after mobilization.

Can you mobilize on short notice for emergency work? Yes, with lead time as short as 1–2 weeks for small crews. Emergency mobilization depends on welder availability at the moment of request — our welding coordination publishes a rolling availability view to our main contractor partners on request.

Do you handle turnaround work outside Sweden/Finland/France? Our current portfolio is Sweden-heavy with campaigns also in Finland and France. We’re open to adjacent European markets (Norway, Denmark, Germany, Benelux) on a project basis — let’s discuss scope.

How do you handle WPQR gaps when a client specifies a material we haven’t welded before? Gaps are identified in the RFQ phase. If new procedure qualification is required, we can either run it against our lead time or use a main contractor’s qualified WPS under their welding coordination. Either model is honest and we tell you upfront.

What’s your shutdown-versus-project mix? Most of our 2024–2025 work has been turnaround-based. The Stegra prefabrication campaign is the exception — a scheduled, non-outage fabrication project. We’re comfortable in both modes.
