Knowledge and understanding skills The course aims at providing students with the capability of understanding a modern approach to structural scantling and analysis, with reference to different ship types, present theories and most recent regulations. Fundamentals will be given to attack problems typical of Ship Structures, possibly having also some degree of complexity, taking into account also possible emerging areas. Course topics will be addressed making reference to analytical and numerical methods. Multidisciplinary aspects of the subject will also be highlighted, both from a theoretical as well as from a design perspective. Knowledge and understanding applied skills The student will be able to apply the knowledge acquired during the course to standard problems associated with the scantling and analysis of ship structures. The student will also have acquired the required fundamentals for developing a creative approach to problem solving. The student will be able to understand and critically interpret a regulatory text. Making judgements The student will be able to analyse a problem related to the scantling and analysis of ship structures and choose the most appropriate approach for its solution. The student will be able to interpret alternative regulations and decide on the most appropriate ones for the considered problem. Communication skills The student will be able to clearly communicate the result of the solution of a problem related to the scantling and analysis of ship structures.

The course is subdivided in lectures, seminars, exercises and homework connected with the theory, IMO regulations, classification societies rules and design aspects.

Oral examination. The oral examination consists in three questions: two concerning the theory, its regulatory aspects and the design implications, and one numerical or graphical exercise. Exercises assigned in class are mandatory for the admission to the examination and must be submitted as a report one week prior the exam date.

This course explores topics closely related to one or more goals of the United Nations 2030 Agenda for Sustainable Development.
