The Material Engineer is responsible for material selection, corrosion control, welding and coating specifications, QA/QC oversight, and technical assurance for subsea pipelines and associated subsea structures in a shallow-water development. The role ensures compliance with industry standards, project requirements, and long-term asset integrity needs.
Key Responsibilities
- Develop material selection reports for linepipe, fittings, PLET/PLEM structures, CRA materials, and flanges.
- Define corrosion allowances and pressure/temperature class requirements.
- Ensure compliance with DNV-ST-F101, API 5L, ISO 13628, and API 17D standards.
Corrosion Engineering & Protection Systems
- Define internal and external corrosion protection strategies.
- Review cathodic protection (CP) design calculations, anode systems, and coating specifications.
- Evaluate inhibitor, MEG, and chemical injection requirements and conduct corrosion risk assessments.
- Review WPS, PQR, and welder qualification records.
- Support weld overlay, clad systems, and heat treatment requirements.
- Review NDT requirements and conduct weldability assessments.
Coating & Field Joint Protection
- Define external coating systems and field joint coating (FJC) requirements.
- Review coating procedures, qualification testing, and mechanical protection systems (CWC, anti-buckle sleeves).
Pipeline Integrity & Technical Assurance
- Review fracture toughness, sour service suitability, fatigue performance, and material traceability.
- Participate in integrity reviews, audits, and resolution of NCRs.
- Support failure investigations and root‑cause analyses.
Interface Management
- Interface with pipeline, structures, umbilical/controls, fabrication, and installation teams.
- Ensure alignment of material specifications across all engineering disciplines.
- Review linepipe mills, CRA vendors, bend manufacturers, and coating plants.
- Participate in FAT and mill testing activities (DWTT, Charpy, CTOD) and coating trials.
- Monitor compliance with ITPs, QCPs, and QA documentation.
Technical Competence Requirements
- Strong knowledge of metallurgy (carbon steel, alloy steel, duplex/super duplex).
- Expertise in internal/external corrosion and CP design.
- Knowledge of offshore coating and insulation systems (FBE, 3LPE, PP).
- Experience with welding metallurgy, HAZ control, and NDT techniques.
- Familiarity with DNV-ST-F101, API 5L, ISO 15156/NACE MR0175, and API 17D standards.
Qualifications & Experience
- Bachelor’s degree in Materials, Metallurgy, Mechanical, or Corrosion Engineering.
- Minimum 12 years’ experience in subsea/offshore materials engineering.
- Experience with linepipe mills, coating yards, and offshore field joint coating (FJC).
- Strong technical communication skills and QA/QC background.
