Corrosion Engineer

Overview

Corrosion Engineer

Corrosion Analysis & Mechanism Identification

• Analyze and identify active and potential corrosion mechanisms in LNG processing, gas treatment, and associated utility systems (e.g., sweet/sour corrosion, CO₂ corrosion, H₂S-induced cracking, under-deposit corrosion, and microbiologically influenced corrosion – MIC).
• Review process parameters (temperature, pressure, flow regime, fluid composition) to predict corrosion behavior.
• Investigate corrosion-related failures and prepare root cause analysis (RCA) reports.

Corrosion Monitoring & Mitigation Strategies

• Develop, implement, and manage corrosion monitoring programs including corrosion coupons, electrical resistance (ER) probes, linear polarization resistance (LPR) probes, and ultrasonic thickness monitoring.
• Design and recommend chemical treatment programs (corrosion inhibitors, biocides, scale inhibitors, oxygen scavengers) in coordination with process and chemical engineers.
• Establish key performance indicators (KPIs) for corrosion control effectiveness.

Material Selection & Coating Systems

• Evaluate and recommend appropriate metallic and non-metallic materials for new installations and replacement components based on process conditions and corrosion resistance.
• Assess and approve coating, lining, and cladding systems for internal and external corrosion protection.
• Review material test certificates (MTCs) and verify compliance with project specifications.

Risk-Based Inspection (RBI) Assessments

• Conduct RBI assessments in accordance with API 581 / API 580 methodologies to optimize inspection intervals and reduce unnecessary downtime.
• Integrate corrosion study outputs (corrosion loops, damage mechanisms) into RBI models.
• Work closely with inspection teams to translate RBI findings into actionable inspection plans (UT, radiography, CVI, etc.).

Life Extension & Asset Integrity

• Provide technical recommendations for life extension of aging assets, including pressure vessels, piping, heat exchangers, and storage tanks.
• Perform remaining life assessments and corrosion rate calculations using historical thickness data.
• Recommend mitigation measures such as weld overlay, clad repair, chemical injection changes, or operational parameter adjustments.

Documentation & Compliance

• Prepare and maintain corrosion management manuals, corrosion control documents (CCDs), and corrosion loop diagrams.
• Ensure all activities comply with NACE, API, ASME, and client integrity management standards.
• Present findings and recommendations to internal integrity teams and client representatives.
