Course Modules - Corrosion in the Offshore Environment
Module Leader
Dr Mike J Robinson
Aim
To provide a knowledge and understanding of the corrosion processes that occur on a range of materials in the offshore (including oil and gas) environment.
Syllabus
- Thermodynamics of corrosion: Electrode reactions, potential. Simple cells, elecrochemical series, galvanic, series. Nernst equation. Common cathodic reactions. General corrosion. Pourbaix diagram.
- Corrosion kinetics: Polarisation diagrams, Practical measurements, passivity.
- Corrosion mechanisms: Effects of oxygen and carbon dioxide, Galvanic corrosion, Pitting and crevice corrosion, Mechanical interactions, Microbial corrosion, Corrosion of welds, Stress corrosion cracking, Hydrogen embrittlement and effects of H2S, High temperature corrosion.
- Corrosion control: Paints, cathodic protection, Corrosion resistant alloys, corrosion monitoring, control by design
Intended Learning Outcomes
On successful completion of this module the student will:
- Have a good knowledge of the principles of corrosion and the factors that affect its rate
- Be able to recognise the main types of corrosion and be aware of the conditions under which they can occur
- Understand the principal methods of corrosion protection and be able to select appropriate methods of corrosion control
