Teaching Rationale And Relationship
Lecture notes and pre-reading materials given out on BlackBoard together with recap content will familiarise students with the basic concepts of naval issues. Lectures will formalise learning related to the fundamental subject of naval architecture and specifically ship stability and motion in waves together with ship structures.
Lectures are used to communicate the fundamentals of ship motions in waves (IKO1-13).
Seminars are used for in-depth examination of some key issues (ISO1-14), with formative assessment used for examination of key issues (ISO7-8).
The Graduate Skills Framework entries indicated as 'A' are also assessed in this way.
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
Knowledge of the concepts, processes and algorithms and the associated regulatory framework associated with ships stability is assessed in the examination (IKO1-IKO17).
