Study Notes

Ship Design and Construction (General Introduction)

  • Basic Terms:

    • Hull: The main body of the ship.
    • Superstructure: Structures above the main deck.
    • Machinery: The engines and other mechanical equipment of the ship.
    • Stern: The rear end of the ship.
    • Bow: The front end of the ship.
    • Deck: The upper surface of the ship.
    • Engine Room: Where the main engines are located.
    • Propeller Shaft: Connects engine to the propeller.
    • Bow Thruster: A propeller for maneuvering the front end of the vessel.
    • Rudder: Controls the ship's direction.
    • Bulbous Bow: A rounded part of the bow that reduces waves.
    • Amidships: The central part of the ship.
    • Beam: The maximum width of the ship.
    • Hold: Cargo space inside the ship.
  • Types of Vessels:

    • Multi-purpose vessel: A vessel designed to carry many types of goods.
    • Oil tanker: A vessel specifically designed to carry oil.
    • Container vessel: A vessel designed to carry containers.
    • Roll-on/roll-off ship: A ship designed to transport vehicles that can drive on and off.
    • Bulk carrier: A ship designed to transport large, bulky goods like coal, ore.
  • Ship Parts and Functions:

    • Hull: The actual shell of the ship including superstructure.
    • Machinery: Includes the main engines as well as auxiliary machinery like boilers, generators for manoeuvring purposes, steering, mooring, cargo handling and other services.
    • Fore-end: The forward part of the ship called bow.
    • Aft-end/Stern: The rear part of the ship.
    • Amidships: The area between the ends of the ship.
    • Beam: Maximum width of the ship found in the amidships section.
    • Bow thruster: Used for manoeuvrability in confined waters.
    • Rudder: Enables the vessel to maintain its course, located right aft.
    • Bulbous Bow: Installed in modern vessels for comfort and speed improvement while in ballast.
    • Hold: The large unobstructed space for carrying goods.
  • Ship Design Considerations:

    • Ship design varies depending on the type of cargo to be transported.
    • Ships need to be self-sustaining in their environments and have high reliability over long periods.
    • Three main areas of skill are involved in ship design and construction (naval architect, navigating officer(deck officer), and marine engineer (engineering officer).
