Teaching Rationale And Relationship

Lectures are designed to convey the underlying concepts and knowledge of marine structural response analysis (IKO1 –IKO9) and the professional skills required to solve marine structural problems (ISO1 – ISO9).
Tutorials support the students' self-study in reading around the lecture material and learning to solve marine structural problems posed by the tutorial questions (ISO1-ISO9).
Practical sessions are self-organizing activities in which the students develop intellectual and problem-solving skills to analyze marine structures (ISO1- ISO9).
Independent study gives time for the students to read recommended references (IKO1-IKO9) and practice their professional skills (ISO1-ISO9).

Assessment Rationale And Relationship

The examination is an appropriate way to assess both theoretical understanding and problem-solving skills under time-constraint as required in industry. The assignments enable a more realistic engineering problem to be set to assess subject specific and cognitive skills. Two ‘low stakes’ coursework assignments (<30%) are incorporated in this module as they are found beneficial for one-year Master’s programme.
Through the Design and creative project, theories and knowledge can be reflected, thus is suitable for assessment of the theoretical knowledge and engineering applications. Problem solving exercise is a good way to develop problem solving skills through tutorial practical and theoretical questions.
