Review and provide feedback on scopes and specifications as needed for complex projects such as close-interval surveys and other field surveys including remedial actions, stray current testing and mitigation, data interpretation and engineering analysis, cathodic protection design, internal corrosion mitigation system design and monitoring including coupons and solid/liquid/gas sampling analyses, and programs for monitoring, assessment and mitigation of complex corrosion mechanisms such as SCC, high-temperature corrosion and microbiological influenced corrosion. Provide technical expertise and assistance in problem-solving to the field-based corrosion supervisors and corrosion technicians for complex corrosion control issues such as stray current, remedial actions, AC mitigation, atmospheric and underground coatings, electrical isolation, above-ground surveys such as close-interval survey, DCVG and ACVG, design for specialized or complex cathodic protection systems, and internal corrosion monitoring programs.
