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. Introduction to irregular waves and ocean wave statistic. Introduction to methods used for finding the necessary terms including strip theory and seakeeping experiments.
Development of the translation motion (heave) predictions and introduction to rotation motions including pitching and rolling motion. Introduction to various types of seakeeping event and to the probability of an even occurring, including: the normal probability density function; significant amplitudes; joint probabilities.

Structures:
global loading and response of ships; local loading and response of ships; fundamentals of finite element analysis (FEA) of ship structures; FEA stiffness matrix; bar elements; beam elements; ship grillage analysis; equivalent nodal loads; practical FEA methods

Resistance
Ship resistance estimates: ship drivetrain and various efficiencies/loss; resistance components; methods used to estimate different resistance components; effective power prediction using statistical and graph methods

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

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 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.
