Senior Welding Engineer

Worked with commercial and operation teams in North America and Asia to develop pipeline with enhanced wear resistance for oil sands operation. Developed and implemented welding PQR & WPS and line pipe specification for the slurry pipeline. Ensured quality control QA/QC and developed inspection programs. Played leadership roles in coordinating several welding training programs in corporation.

Pipeline Integrity / Reliability: Developed and implemented weldable wear-resistant high manganese steel, improved product quality, extending life-time of the slurry pipeline. Increased productivity by decreasing maintenance time. Saved $1-2B in oil sands operation costs.

oDesigned and fabricated high manganese steel welding consumables for manual / automatic welding.

oConducted root-cause failure analysis (RCFA), identifying factors that cause failure in oil sands and sour service pipelines and subsea flexible pipes. Provided guidelines for pipeline operation, inspection, maintenance, and repair to implement corrective and preventative actions in compliance with procedures and regulations.

oMonitored wear and corrosion in pipelines that influence reliability of pipeline.
