|Planned learning activities and teaching methods||
The taught part of course is delivered to the students by means of lectures, conducted with the help of computer presentations. Lecture notes and presentations are available through the web for students to use in combination with the textbooks.
Lectures are supplemented with laboratory sessions with aim to get acquainted of a variety of inspection techniques used on structures in the offshore environment.
