When a production facility shuts down for scheduled
or unscheduled maintenance, alterations, or inspections,
Willda Group has a complete range of integrated services
to provide cost-effective, practical support, including :

Shutdown Maintenance
  • Engineering/project management
  • Hydrotesting
  • High-pressure water jetting
  • Camera inspection
  • Flange management (including hydraulic bolt torquing and tensioning)
  • Flange machining
  • Process drying
  • Nitrogen Purging
  • Nitrogen/Helium Leak Testing


By integrating all the above-related services into a single integrated solution, the use of a small team of multi-disciplined personnel, with the capability to perform all maintenance operations required for a shutdown, can substantially reduce man-hours, accommodation requirements, travelling and logistical costs, thereby considerably reducing the total cost of a shutdown.



  • Reduced down-time, allowing optimisation of production
  • Enhanced overall safety through elimination of risks related to transfers and poor communication
  • Reduced costs
  • Reduced workforce therefore less bed space requirements
