The chapter further discusses the principal materials used in the construction of the main components of a ship or marine structure, including steels, aluminum alloys and composites, the effects of corrosion, corrosion control, and antifouling. The ship owner's operational requirements need to be established during preliminary designing, which then allows the development of a basic specification such as deadweight, speed, range, capacity, stability, and freeboard. The preliminary design process will normally take the form of a techno-economic appraisal, using a fundamental engineering economy approach. The ship design process may be broken down broadly into two stages: Conceptual and/or preliminary design and detailed or tender or contract design. This Chapter provides a broad overview of ship design, construction and operation.
