Preface
Shipping is responsible for 90% of world trade. The design, equipment and function of ships are subject to constant evolution that intensified recently because of emerging sustainability and safety requirements, the changing patterns of world trade and technological evolution.
It is becoming increasingly evident that the Naval Architects and Marine Engineers of the future will be less tied to conventional ship types, will work in less deterministic ways and will have to adapt to market demands. Yet good understanding of the basics shall remain essential.
With the above in mind, this set of lecture notes outlines some of the Principles of Naval Architecture and some Marine Engineering concepts for use in concept ship design. The material presented can be used by undergraduate students or early stage postgraduate students of Marine Technology. I am grateful to my Teaching Assistants Zeiad Abdelghafor, Hassan Yosri and Sarah Blackwell for helping me to conceptualize the material presented.
