Shutdown Inspection Services for Industrial Projects

Dilenza provides shutdown inspection services for industrial plants, facilities and assets requiring qualified welding and coating inspectors during shutdowns, turnarounds, outages, maintenance campaigns and major repair programs.

These projects often compress significant volumes of work into a limited period. Inspection resources must therefore be technically suitable, available when required and capable of operating within demanding project schedules.

Dilenza provides inspectors for defined shutdown activities, temporary full-time assignments, multiple shifts and larger inspection teams according to the technical scope and project schedule.

  • Welding & coating specialists

    Qualified inspectors aligned with the technical scope

  • Intensive project schedules

    Day shift · Night shift · Extended hours · Multi-inspector teams

  • Repair and maintenance support

    Inspection from preparation through final verification

  • Worldwide coverage

    Europe · Middle East · Asia · Africa · Americas

Shutdown reality

Inspection When Every Hour Matters

Shutdowns and turnarounds operate differently from normal production.

  • Equipment is taken out of service.
  • Maintenance, repairs, replacements and modifications may occur simultaneously.
  • Several contractors may work across different areas.
  • Inspection points can arise rapidly.
  • Schedules are compressed, and delays can affect the planned return to operation.

Inspection coverage therefore needs to be defined before the shutdown begins and remain flexible enough to follow the actual work.

Dilenza supports welding and coating inspection during these critical project windows with qualified inspectors selected according to the required technical activities, qualifications, schedule and location.

A shutdown is temporary. The consequences of the work performed during it are not.

Two disciplines

Welding and Coating Inspection During Shutdowns

  • Shutdown Welding Inspection

    Shutdown programs frequently involve welding activities associated with maintenance, repair, modification and equipment replacement.

    Depending on the project scope, Dilenza welding inspectors may support:

    • Welding procedure review
    • Welder qualification verification
    • Material traceability
    • Joint preparation
    • Fit-up inspection
    • Welding surveillance
    • Preheat and interpass monitoring
    • Welding parameter verification
    • Visual welding inspection
    • NDT witnessing
    • Weld repair inspection
    • Dimensional verification
    • Final inspection
    • Welding documentation review

    Typical shutdown welding activities can involve:

    • Process piping
    • Pressure vessels
    • Heat exchangers
    • Boilers
    • Storage tanks
    • Structural steel
    • Supports
    • Skids
    • Equipment modifications
    • Replacement components
  • Shutdown Coating Inspection

    Shutdowns can also create a limited window for protective coating repairs, refurbishment and recoating.

    Dilenza coating inspectors may support:

    • Surface-condition assessment
    • Surface-preparation inspection
    • Surface cleanliness
    • Surface profile
    • Environmental-condition monitoring
    • Coating-material verification
    • Application surveillance
    • Wet-film thickness
    • Dry-film thickness
    • Holiday testing
    • Adhesion testing
    • Repair inspection
    • Final coating verification

    Typical applications can include:

    • Tanks
    • Piping
    • Structural steel
    • Process equipment
    • Marine structures
    • Industrial equipment
    • Corrosion-damaged areas
    • Repaired steelwork

Suitability

When Shutdown Inspection Support Is Needed

  • Major Planned Turnarounds

    Large plants may require several inspection professionals during scheduled maintenance and equipment overhaul periods.

  • Welding Repair Campaigns

    Inspection may be needed throughout preparation, repair welding, testing and final acceptance.

  • Equipment Replacement

    New piping, vessels, structural components or fabricated equipment may require inspection during installation.

  • Coating Repair and Refurbishment

    Shutdown access can provide the opportunity to inspect and restore protective coating systems that cannot be serviced during normal operations.

  • Temporary Increase in Inspection Workload

    Internal quality teams may require additional qualified resources during the shutdown period.

  • Multiple Work Fronts

    Parallel maintenance areas may require several inspectors to maintain adequate technical coverage.

Compressed schedules require inspection that is prepared before the work accelerates.

Coverage

Shutdown Inspection Coverage Models

  • Single Specialist Inspector

    Suitable for a defined welding or coating scope within a limited project area.

  • Full-Time Shutdown Inspector

    A dedicated inspector attends throughout the planned shutdown period.

  • Multiple Inspectors

    Several inspectors may be required where multiple work fronts operate simultaneously.

  • Day and Night Shift Coverage

    Where work continues around the clock, inspection can be structured around separate shift requirements.

  • Welding + Coating Team

    Separate qualified professionals can support welding and coating activities occurring within the same shutdown.

  • Rotational Coverage

    For extended or remote shutdown projects, rotational arrangements may be appropriate.

Preparation

Planning Inspection Before the Shutdown

Effective inspection support should ideally be defined before the outage begins.

Key information includes:

  • Technical Scope

    • Equipment involved
    • Expected welding activities
    • Expected coating activities
    • Repair scope
    • Inspection points
    • Applicable standards
  • Inspector Requirements

    • Required certifications
    • Industry experience
    • Site approvals
    • Safety qualifications
    • Language requirements
  • Project Schedule

    • Shutdown dates
    • Working hours
    • Shifts
    • Expected peak workload
    • Number of work fronts
  • Documentation

    • ITP
    • Repair procedures
    • Welding procedures
    • Drawings
    • Coating specifications
    • Inspection procedures
    • Acceptance criteria
  • Reporting

    • Daily reporting
    • Shift handovers
    • Observation escalation
    • Repair tracking
    • Final documentation

Early planning allows inspection resources to be aligned with the actual shutdown workload rather than reacting after work has already started.

Compare

Shutdown vs Short-Term Inspection

  • Short-Term Inspection

    Best suited to a defined limited assignment without the operational intensity of a plant shutdown.

  • Shutdown Inspection

    Best suited when:

    • A plant or asset is temporarily taken out of service
    • Many maintenance activities occur simultaneously
    • Schedule pressure is significant
    • Multiple shifts or inspectors may be required
    • Repairs and re-inspection occur continuously
    • Return-to-service timing is critical
