Objectives:To make the students understand the basic principles of design of ocean structures. The course will cover the wide areas such as coastal structures (breakwaters, jetties, ports and harbours) and offshore structures (fixed platforms, floating structures) and the wave-structure interaction; The course is designed to to give understanding of design principles so that the students can take further elective subjects in the related field during the next semesters. Further, it will help the students choose the final year project in their interested areas in ocean structures.
