Microbiologically Influenced Corrosion (MIC) is a type of corrosion caused by the presence and activities of microorganisms, such as bacteria, fungi, and algae, on the surfaces of pipelines. MIC is a significant contributor to the estimated at around $2.5 trillion global cost of corrosion. This form of corrosion is particularly impactful in the oil and gas industry due to its potential to cause severe damage to pipelines and other infrastructure. Implications for pipeline operators include:

•    Structural Integrity threats: MIC can significantly compromise the structural integrity of pipelines, leading to leaks, ruptures, and potential environmental hazards.

•    Increased maintenance and repair costs: Addressing MIC requires regular monitoring, maintenance, and, at times, costly repairs or replacements of affected pipeline sections.

•    Regulatory non-compliance: pipeline operators must adhere to regulations that mandate the monitoring and control of MIC to prevent environmental contamination and ensure safe operations.

DNV helps its customers mitigate MIC in their pipeline infrastructure by using the latest industry detection technologies, including techniques such as ultrasonic testing, radiography, and microbial analysis. DNV offers a wide variety of MIC and microbiology services, including conducting MIC threat assessments, screening biocides and optimizing biocide dosage, testing the combined effects of process chemicals, providing an on-site mobile lab for mitigation optimization and testing, and qualifying MIC mitigation and monitoring technologies.

By understanding and addressing MIC, pipeline operators can improve the longevity and safety of their infrastructure, ultimately reducing the risk of failures and associated costs.
