Section A - Ship Construction

introduction - Development of ocean-going Merchant Ships. Modem merchant ships. Types of Ships - Types of ships based on nature of cargo. Passenger Liners, Ferries. Specialized carriers for General Cargo, Bulk, Oil (Crude Oil Products) OBO's. Container, RO-Ro, Lash, LPG, LNG, Cattle, cars, etc. Special features of above types of ships.

Definitions & Meanings :-

LAO, LBP, EB, MB, Depth, Draft, Freeboard, Camber, Sheer, Rake, Rise of floor, etc.

Principal Parts of A Ship :-

Bow, Stem, Shell plating, Double Bottom Tanks, Cargo Holds, Tween Decks, Deep Tanks, Fore-peak and After Peak store rooms and tanks, Plate Keels and Duct Keels. Forecastle deck, Quarter Deck, MainlWeather decks, Hatch covers, Cargo Gear, anchoring and mooring equipment, etc.

Machinery Spaces:-

Superstructure:-

Wheel House, accommodation spaces, cabins, galley, pantry, dining saloons, recreation rooms, various stores and lockers, cold storage spaces etc.

General Layout of Ships:-

General Cargo Ship, Bulk Carrier, Oil Tanker and Container Ship. Simple sketches of the same.

Principles of Design:-

Common principles governing design and construction of various types of steel ships with respect to:
a) Longitudinal, transverse and vertical strength.
b) Continuity of strength.
c) Strength - under static and dynamic conditions.
d) Stability.
e) Water-tightness.
f) Conformity with statutory requirements.

Steel for Ship Construction:-

Types of steel used in ship construction. Steel plates and their treatment. Rolled sections - various shapes and standard sizes. Castings and forgings and their use in construction. Testing of materials - various tests at production and building stages.

Riveting and Welding:-

Riveting as a joining process. Welding - its pre-dominant use in ship construction. Advantage of welding over riveting in ship construction. General ideas of Electric Arc welding - equipment, coated electrodes, methods used etc. welding and Gas cutting Precautions while welding.

Section B - Ship Stability

Laws of flotation, Buoyancy, Reserve buoyancy. Displacement, Deadweight. Change of draft due to change of density. TPC, FWA, DWA. The centre of gravity of a ship and factors affecting the same. The centre of buoyancy and factors affecting the same. Calculations involving KG and KB of a ship. The meaning of the terms Block co-efficient. Water-plane coefficient. Mid-ship Coefficient, Prismatic Coefficient and relationship between them. Use of displacement and TPC curves and scales to determine weights of cargo or ballast from draughts or freeboards. Metacentric height, Righting lever, Righting Moment, Stable, Unstable and Neutral equilibrium. Free Surface Effect. Stiff and Tenor ships. Difference between heel and list. Use of hydrostatic tables and curves as supplied to ship. Calculations based on the foregoing topics.
