Planned learning activities and teaching methods |
The taught part of course is delivered to the students by means oflectures, conducted with the help of computer presentations. Lecture notes andpresentations will be available through the web for students to use incombination with the textbooks. Lectures will be supplemented with homeworkassignments to develop knowledge and computational skills on the variousmodulus of the course (hydrostatic stability, regular and irregular waves andmodelling of random seas, computation of wave loads on slender and large volumemarine structures. | ||||||||||
