SECTION A - SHIP STABILITY

1. Use of Simpson's Rules for the computation of areas, second moment of areas, volumes, moments of volumes and centriods. Centre of pressure for regular shapes and parabolic shapes, when given horizontal or vertical ordinates.

2. Derivation of the formulate for TPC, FWA, BM (Transverse), MCTC, Angle of Loll, Virtual loss of GM due to free surface. Virtal loss of GM on dry docking, list with Zero GM, Wall sided formula and Attwood formula.

3. Stability at moderate and large angles of heel. Use of the wall-sided formula.

4. Effect of beam and freeboard on stability.

5. Dynamical Stability - calculation of same by the GZ curve.

6. Stability and trim when dry-docking or grounding.

7. Theory of rolling. Synchronism.

8. The danger to a ship at the angle of loll. Ballasting sequence to rectify same.

9. Dangers to a ship with a heavy list. Dangers associated with deck cargoes including timber. Preventive and corrective actions to take.

10. Billing of compartment. Permeability of a compartment. Calculation on bilging and flooding of a compartment.

11. The Inclining Experiment

12. Shearing Forces and Bending Moment. The ship as a box girder. The calculation, and graphical representation, of the SF and BM for box-shaped vessel, on even keel, under various conditions of load.

13. Modern methods of determining the effect of different conditions of load and ballast on the ships structure and stability - Loadicator.

14. Calculations based on the foregoing and on the syallabii of the first and second years.

Section B - Ship Construction

1. Properties of steel, aluminium and other construction materials used for shipbuilding. Effect of fire, heat, shock etc., on these materials.

2. Types of ships. General ideas on strength and construction. Midship sections of specialised carriers - Passenger ships, Rolash, Refrigerated cargo, LNG, LPG, Chemicals, etc.,

3. An out-line knowledge of shipyard practice and procedure including drawing office methods, place and section marking; process control and prefabrication.

4. Methods used in welding of steel ships. Welding of ferrous and non-ferrous metals as practised in Shipyards. Testing and inspection of welds. Types of joints and edge preparations. Stresses set up due to welding. Stress relieving.

5. Classification Societies and their functions. Cargo Ship Construction Rules. An outline knowledge of Tonnage Regulations.

6. Load Line Regulations. Assignments of freeboard. Subdivisional Load Lines on passenger ships.

7. Structural fire protection on Passenger and Cargo ships.

8. Knowledge of application of floodable length curves. Factor of subdivision. Criterion of service numeral. Permissible length affecting hull division on passenger ships.
