Abstract
Corrosion/erosion management for an operation is the systematic application of policies, practices, and resources to control corrosion/erosion and provide reliable safeguards against unexpected failures and leaks that can jeopardize mechanical integrity, operation, health, safety and environment (HSE). This paper highlights the use of a single key performance indicator in tracking monitoring strategy, mitigation strategy, and pipeline integrity for aboveground pipelines in the North Slope. The approach enables the integration of corrosion/erosion control, process monitoring, inspection, mitigation, environmental control, and materials management into a comprehensive management strategy. In this instance, external corrosion and stress corrosion cracking are effectively controlled; consequently, internal corrosion becomes the sole time-dependent failure type. Internal corrosion rate, like any KPI, enables the organization to operate with greater efficiency, reliability and control. The approach underscores a strategy that ensures that the facility remains fit for purpose during its design life. It satisfies the need to proactively control corrosion from growing to a size that could affect the structural integrity of components so that the facility remains sound and capable of safely performing the tasks for which it was designed and is compliant with the applicable regulations and standards governing design, operation, and maintenance.
