|Planned learning activities and teaching methods||
The taught part of course is delivered to the studentsby means of lectures, conducted with the help of computer presentations.Lecture notes and presentations will be available through the web for studentsto use in combination with the textbooks.Lectures will besupplemented with a case – study project that will be carried out using thecomputer software XMOOR, suitable to analyse multi-leg mooring systems.Moreover, lectures will be supplemented with homework assignments to developcomputational skills on the various modules of the course.
