4. III.4 – Yard/Construction OJT and competency sign-off (Months 4–9)
   • Accumulate supervised hours in VT and chosen NDT methods on actual weld joints (butt, fillet, T/K/Y joints, pipeline girth welds).
   • Work through Inspection and Test Plans (ITPs), witnessing WPS/PQR/WPQ, and documenting NCRs and concessions.
5. III.5 – Offshore readiness (Months 6–12)
   • Add rope access Level 1 if your market prioritizes access-based inspection.
   • Undertake company-specific permit-to-work and SIMOPS inductions when hired.
   • Secure first offshore rotation via fabricator/contractor placements or short-service personnel programs; search jobs on Rigzone.
6. III.6 – Differentiation and specialization (Months 9–18)
   • Add PAUT/TOFD or Coatings Level 2 to broaden scope and increase utilization during weather downtime.
   • Take ISO 9001 Internal Auditor to support vendor audits and NCR closeout effectiveness reviews.
7. III.7 – Documentation and compliance (Ongoing)
   • Maintain a controlled copy of certifications, CPD hours, eyesights, equipment calibrations, and logbook with weld counts and defect stats.
   • Prepare for 5-year ISO 9712 renewals by tracking method-specific experience and CPD.

Technical formulas and quick-reference for inspectors

Fillet weld effective throat: The effective throat thickness t of a 45° fillet weld with leg size z is \( t = 0.707\,z \).

Heat input (kJ/mm): \( Q = \dfrac{V \times I \times 60}{1000 \times S} \), where V = volts, I = amperes, S = travel speed (mm/min).

Carbon equivalent (IIW, for preheat estimation): \( CE = C + \dfrac{Mn}{6} + \dfrac{Cr + Mo + V}{5} + \dfrac{Ni + Cu}{15} \).

Out-of-roundness (ovality) in pipes: \( \%\,Ovality = \dfrac{D_{max} - D_{min}}{D_{nom}} \times 100\% \).

Porosity area fraction (visual sampling): \( A_f = \dfrac{\sum A_{p}}{A_{inspect}} \times 100\% \) compared against code-limited maxima.
