Pulp & Paper

The challenge

Paper mills are continuous-process facilities. They run 24/7 for months or years between scheduled outages, and when they come off-line for maintenance, every hour counts. The operating rhythm is unforgiving: the outage plan specifies the window, and the plant expects to be back in production on schedule regardless of what unexpected scope emerges mid-job.

Mill work adds specific challenges: high-temperature process equipment, corrosive pulp and chemical handling, large mechanical installations integrated with process piping. A welding subcontractor working in a mill needs the discipline to deliver within the window, the adaptability to handle emergent scope, and the safety integration to work around adjacent operating equipment.

What we deliver

• Equipment replacement — dismantling of obsolete units, installation of new equipment with welded tie-ins
• Piping modification and repair — process piping, steam, condensate, and utility lines
• Welded structural support — hangers, racks, and supports for new or replaced equipment
• Shutdown campaign execution — integrated into the mill’s outage programme

Standards and codes

• ISO 3834-2 — welding quality framework
• EN 13480 — metallic industrial piping
• EN 1090-2 — structural steel execution for supports
• ISO 45001 — safety management
• Plant-specific HSE codes and permit-to-work systems

Operating mill integration

Paper mills are typically partially operating even during outage windows — one line down, others running. This means our crews work with active hot work permits, exclusion zones, and adjacency awareness. Our approach:

• Pre-mobilization plant-specific HSE induction
• Daily toolbox talks with the main contractor’s safety lead
• Tight coordination with mill operations on isolation and de-isolation
• Clean handover of completed tie-ins with full test pack documentation

Why mill operators and main contractors bring MIDAS on

• Operating mill experience — Arctic Paper 2025 campaign
• Welded tie-in discipline — test pack per spool, traceability per weld
• Nordic main contractor integration — AK Serisė UAB partnership
• Flexibility on scope that emerges mid-outage
