Siavash is a pipeline integrity TA with extensive experience (after year 2000) in pipeline integrity engineering and management gained through working for renowned consultancies and operating companies. Siavash has over 18 years of experience in oil and gas industry both in technical and managerial roles specializing in Pipeline integrity management systems, Pipeline defect assessments, ILI verifications and operations (MFL, TFI, UT, EMAT), risk-based integrity management and assessment of onshore and subsea pipeline systems, pipelines pigging, pipeline life extension/remaining life assessment calculation for in-service onshore pipelines (hazardous liquids and Natural gas pipelines); Engineering Criticality Assessment (ECA), Metal loss (General corrosion, local thin area, pitting) FFS, Dent and gouge assessments. Siavash has also expertise in Welding, corrosion and CP studies and pipeline repair methods (onshore).
