Future Solutions

Course Overview:

  • Corrosion is a major threat to the oil and gas, petrochemical and other process-intensive industries and is responsible for countless of dollars in damage and maintenance costs.
  • Additionally, ageing equipment becomes more susceptible to corrosion and loses its ability to withstand harsh operating environments (e.g. high temperature and pressure).
  • The purpose of a strong corrosion monitoring program is to improve safety, reduce maintenance and inspection costs, and maximize efficiency.
  • Corrosion monitoring plays a vital role throughout the equipment lifecycle.
  • Inspection and monitoring strategies and techniques may change according to the age and condition of equipment. Therefore, inspection and monitoring strategies should be reviewed at specific intervals at the owner-operator’s discretion.
  • The goal of this course is to provide interested persons with a basic overview of the theoretical and practical aspects of corrosion and its control.

What are the Goals?

By the end of the training, participants will be able to:

  • Recognize the different inspection tools and techniques.
  • Be able to evaluate how the cost of corrosion is.
  • Have FOUNDATION Level understanding of how to Analyze annual inspection plans and reports.
  • Be able determine which pipelines need to be inspected.
  • Assesse the need for corrosion and repair as per asset criticality.
  • Conduct (physical) investigations to identify causes of failure and suggest mitigation measures (root cause analysis).

Who Should Attend?

  • Inspection technicians and chemists responsible for inspection programs.
  • Corrosion technicians responsible for corrosion monitoring and field measurement.
  • Asset integrity engineers responsible for equipment health,
  • Operating (field) personnel responsible for collecting samples.
  • QC technicians responsible for field examination and non- destructive testing.

Delivery Method:

The course will be delivered through a combination of lectures, case studies, group discussions, and practical exercises. Participants will engage in interactive sessions to enhance learning and practical application of concepts.
