#### Outline Of Syllabus

Fundamentals and Stability:

Basic naval architectural terms and concepts; basic hydrostatic quantities; metacentric theory and stability; initial stability and the calculation of metacentric height and righting lever; calculation of KG; influence of adding, moving or removing mass. Ship stability; a suspended load, tanks and free surface effect; introduction to static stability, curves of static stability; stability evaluation; IMO criteria, the Stability Booklet. Energy methods and dynamic stability; standard stability cases: the loll ship, wind heeling, crane ships.

Seakeeping:
Introduction to the study of ship motions in waves including: the 6 degrees-of-freedom systems; description of regular waves; derivation of the equations of motion. Introduction to motion of floating bodies in regular waves including the concepts of added mass, fluid damping, restoring forces and wave excitation forces.

##### Teaching Rationale And Relationship

Lecture notes, lecture videos and pre-reading materials given out on Canvas together will familiarise students with the basic concepts of naval architecture topics. Lectures will formalise learning related to the fundamental subject of naval architecture and specifically ship stability, resistance, motion in waves and ship structures.

Should the public health situation require it, the present-in-person teaching activities will be replaced by synchronous online sessions. The PiP lectures and tutorials will be replaced by additional structured, nonsynchronous online materials supported by synchronous online tutorial sessions.

#### Assessment Methods

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).

Should the public health situation require it, the planned examination scheduled to be completed present-in-person will be replaced by an open book, online examination to be completed within a defined 24 hour period.
