GRP Pipeline Inspector (TPI / QA-QC)

About the role

This position is for a GRP Pipeline Inspector (also called TPI or QA-QC inspector) responsible for inspecting glass-reinforced plastic (GRP) pipes and fittings across the manufacturing, installation and quality control stages. The work covers oil and gas, petrochemical, refinery, water transmission, desalination and offshore projects.

Key responsibilities

• Manufacturing inspection: review approved ITPs, procedures, drawings and material specs; verify resin, glass fiber, catalyst and additives; witness pipe manufacturing, curing and FAT; check dimensions, wall thickness, stiffness class, pressure rating and markings
• Incoming material inspection: verify pipes, fittings, flanges, couplings, gaskets and adhesives, check for transport damage and confirm traceability and material certificates
• Installation inspection: check trench preparation, pipe alignment, joint preparation, laminated and adhesive joints, coupling torque and compliance with manufacturer recommendations
• Quality control: visual and dimensional inspection, wall thickness checks, Barcol hardness testing, laminate and joint integrity checks, inspection of field-fabricated spools and fittings
• Hydrostatic and leakage testing: witness tests, verify calibrated gauges, ensure test pressure and holding time meet project specs, monitor pressure drops and review test records
• Documentation: review MTCs, manufacturer data reports, QC records, calibration certificates, hydrotest records and as-built docs; prepare inspection reports and punch lists

Required profile

• Diploma or Bachelor's degree in Mechanical Engineering, Materials Engineering or a related discipline
• Minimum 8 years of experience in GRP piping inspection, preferably in oil and gas, petrochemical, refinery, water transmission, desalination and offshore projects
• Knowledge of GRP manufacturing processes (filament winding, centrifugal casting, hand lay-up)
• Familiarity with AWWA C950, ASTM D3517, D2996, D4161, ISO 14692, ASME B31.3 and B31.4, and client specifications such as Saudi Aramco, ADNOC, KNPC, KOC, PDO and QP
• NDT Level II certification and a valid coating/composite inspection certification are an advantage

Required skills

• Strong knowledge of composite materials and GRP systems
• Ability to read isometric drawings and P&IDs
• Familiarity with QA/QC documentation and inspection procedures
• Report writing and client communication skills
• Understanding of offshore and onshore pipeline construction practices
