Physics and Applied Sciences
Core concepts
Understand mechanics: Newton's laws, momentum, impulse, work, energy, power, circular motion, and gravitation. Study properties of matter: density, pressure, Archimedes' principle, elasticity, and surface tension. Learn heat: temperature scales, specific heat capacity, latent heat, expansion, and heat transfer. Understand waves, sound, light, and basic optics. Study electricity and magnetism: Ohm's law, series and parallel circuits, electrical power, and magnetic effects. Learn the basic structure of matter and radioactivity, including safety precautions.
Common traps
Questions often confuse mass with weight, or heat with temperature. Watch for specific heat capacity being used where latent heat is required. In circuits, series and parallel rules for resistance and current are frequently reversed. Remember that pressure in a fluid acts equally in all directions at a given depth.
Worked example
How much heat is needed to raise 2 kg of water from 20 °C to 80 °C? Q = mcΔT = 2 × 4180 × 60 = 501,600 J ≈ 502 kJ. Rule of thumb: water has a specific heat capacity of about 4.18 kJ/kg·K.
Study approach
Practise numerical problems with units clearly shown. Link physics principles to marine applications such as pressure, buoyancy, and electrical circuits.
Industrial Management, Accounting and Professional Practice
Core concepts
Understand management functions: planning, organising, leading, and controlling. Study organisational structures, leadership styles, motivation theories, communication, and teamwork. Learn production management: work study, method study, time study, quality control, and maintenance strategies including preventive, predictive, and breakdown maintenance. Understand cost accounting: fixed and variable costs, direct and indirect costs, depreciation, break-even analysis, and budgeting. Study professional ethics, codes of conduct, contract types, and the engineer's responsibility for safety and the environment.
Common traps
Questions often confuse fixed with variable costs, or direct with indirect costs. Watch for break-even being calculated in units when contribution per unit is required. Depreciation methods such as straight-line and reducing balance are frequently mixed up. Professional responsibility cannot be delegated to supervisors.
Worked example
Fixed costs are 100,000, selling price per unit is 50, and variable cost per unit is 30. Contribution per unit = 20. Break-even quantity = 100,000/20 = 5,000 units. Rule of thumb: break-even = fixed costs / contribution per unit.
Study approach
Practise cost and break-even calculations, and relate management theory to shipboard and workshop situations. Always justify ethical decisions with reference to safety and the law.
Practical Workshop, Simulation and Industrial Attachment
Core concepts
This domain integrates practical skills with theoretical knowledge. Understand workshop safety, tool handling, measurement, and the correct sequence of machining and assembly operations. Study engine room simulator operations: start-up and shutdown procedures, watchkeeping, alarm handling, and emergency response such as blackout, fire, and flooding. Learn the purpose of industrial attachment: observing real plant, recording readings, understanding maintenance practices, and linking theory to practice. Understand permit-to-work, isolation and lock-out/tag-out, risk assessment, and reporting procedures.
Common traps
Questions often test the correct order of operations, such as isolating before dismantling or testing atmosphere before entry. Watch for emergency procedures being described out of sequence. In simulation, never bypass alarms without authorisation. Attachment reports should record observations and analysis, not just describe equipment.
Worked example
During a simulated blackout, the correct sequence is: confirm the blackout, ensure the emergency generator starts and supplies essential services, secure the main engine, investigate the cause, then restore power in a controlled sequence. Rule of thumb: safety first, then containment, then restoration.
Study approach
Keep a logbook of practical tasks and simulator exercises. Reflect on what went well, what went wrong, and how theory explained the outcome.
