Material & Corrosion engineer

Role Definition

The Material Engineer is responsible for material selection, corrosion control, welding and coating specifications, QA/QC, 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 integrity needs.

Material Selection & Engineering

·       Develop material selection reports for linepipe, fittings, PLET/PLEM structures, CRA materials, and flanges.

·       Define corrosion allowances, 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 CP design calculations, anode systems, and coating specifications.

·       Evaluate inhibitor/MEG/CI requirements and corrosion risk assessments.

Welding Engineering & Fabrication Support

·       Review WPS, PQR, and welder qualifications.

·       Support weld overlay, clad systems, and heat treatment requirements.

·       Review NDT requirements and weldability evaluations.

Coating & Field Joint Protection

·       Define external coating systems and field joint coating (FJC) requirements.

·       Review coating procedures, qualification testing, and mechanical protection (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 resolve NCRs.

·       Support failure investigation and root-cause analysis.

Interface Management

·       Interface with pipeline, structures, umbilical/controls, fabrication yards, and installation teams.

·       Ensure alignment of material specifications across disciplines.

Vendor Qualification & Manufacturing Oversight

·       Review linepipe mills, CRA vendors, bends, and coating plants.

·       Participate in FAT, mill testing (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.

·       12 years’ experience in subsea/offshore materials engineering.

·       Experience with linepipe mills, coating yards, and offshore FJC.

·       Strong technical communication and QA/QC background.
