Master of Science in Offshore Technology - Industrial Asset Management

Universitetet i Stavanger (UiS)

Industrial asset management is a cross-functional discipline combining engineering and management subjects. It is the process of organizing, planning and controlling the procurement, operation and maintenance, and disposal of industrial assets in a safe, environmental friendly and economically efficient way. This includes, for example, operations and maintenance management, cost engineering and economics, diagnostic and prognostic engineering, safety and risk management, industrial services, decision engineering and performance management, as well as the interaction between humans, technology and organizations. Course contents, projects, and problems in the program are often taken from the offshore industry, but the program is designed in such a way that the methods and principles can also be commonly used in other land-based industries.
