E-597 - Corrosion Prevention in Production Facilities

5 days MAT/CORGB
Level
Proficiency
Audience
  • Engineers and technicians working for the design, construction, operation, inspection or maintenance of Oil & Gas upstream production facilities.
Purpose
  • This course provides in-depth understanding of corrosion phenomena specific to Oil & Gas production facilities, and the main corrosion prevention techniques.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • list the main characteristics and types of corrosion of metallic materials used in the Oil & Gas industries,
  • describe the means of protection against each type of corrosion,
  • select the most appropriated material for a given Oil & Gas application,
  • explain the available ways of monitoring the state of corrosion of a metallic equipment.
Prerequisite
  • No prerequisites for this course.
Ways and means
  • Highly interactive teaching by experienced lecturers.
  • Several applications and illustrations.
