How we control quality

Quality control covers material identification and traceability, fit-up, welding, dimensional checks and coating inspection, as required by the project. Inspection and test plans define the applicable hold points, testing and client or third-party inspections. Manufacturing records are compiled for the agreed final documentation package.

  1. Drawing review, revision control and inspection planning
  2. Material identification and traceability
  3. Fit-up, welding and dimensional control
  4. NDT, coating and client or third-party inspection, as specified
  5. Release, and the agreed manufacturing records

Welding control

  • Project-specific WPS and PQR control
  • Welder qualification and continuity tracking
  • Joint preparation and fit-up inspection
  • Preheat, interpass temperature and consumable control
  • Visual and non-destructive testing coordination
  • Repair, NCR and corrective-action management

Health and safety

Risk assessment, induction and toolbox talks support safe execution. Project-specific safety controls are coordinated with production activities.

Surface preparation and coating

Blast cleaning to Sa 3 in accordance with ISO 8501-1, as specified. Painting takes place in two humidity-controlled paint rooms. Marine, industrial, heat-resistant and fireproofing coating systems are applied to project specifications. Coating procedures, dry film thickness, environmental conditions and inspection points follow the project specification.
