BTEB Diploma in Marine Engineering Examination · Work through your exam, one topic at a time.
The BTEB Diploma in Marine Engineering is a technical vocational credential awarded through the Bangladesh Technical Education Board system, aimed at students and working technicians who want a recognised qualification in the operation, maintenance and repair of shipboard machinery. It suits school leavers entering the maritime trades as well as ratings and workshop staff seeking formal progression toward engine-room roles. The BTEB Diploma in Marine Engineering Examination study guide has 11 sections and about 3,382 words.
01Marine Propulsion Systems and Main Engines
A marine engineer must be able to describe the energy chain from fuel to thrust: fuel injection, combustion, expansion, exhaust, and shaft power. Understand the difference between two-stroke slow-speed crosshead engines and four-stroke medium-speed trunk engines, including scavenging, turbocharging, and uniflow exhaust valve operation.
291 words, about 1 min02Marine Auxiliary Machinery and Systems
Auxiliary systems keep the main engine and ship services running. You must know the layout and purpose of bilge, ballast, fuel oil, lubricating oil, cooling water, compressed air, fresh water, and steam systems.
282 words, about 1 min03Ship Construction and Naval Architecture Fundamentals
Candidates must understand hull form terminology: length between perpendiculars, beam, depth, draught, freeboard, camber, sheer, flare, and rake. Know the structural members: keel, keelson, floors, frames, stringers, longitudinals, bulkheads, decks, and shell plating.
292 words, about 1 min04Marine Electrical and Control Engineering
Understand AC and DC generation, three-phase systems, star and delta connections, line and phase relationships, power factor, and the difference between real, reactive, and apparent power. Know the construction and operation of alternators, transformers, circuit breakers, contactors, relays, and protection devices.
289 words, about 1 min05Thermodynamics, Fluid Mechanics and Heat Transfer
Understand the first and second laws of thermodynamics, internal energy, enthalpy, entropy, and the ideal gas laws. Know the Carnot cycle, Rankine cycle, Otto and Diesel cycles, and the meaning of thermal efficiency.
245 words, about 1 min06Engineering Materials
Know the properties of ferrous and non-ferrous metals: plain carbon steel, alloy steel, stainless steel, cast iron, aluminium alloys, copper alloys, and titanium. Understand crystal structure, grain size, and the effects of alloying elements.

Understand measuring instruments: vernier callipers, micrometers, dial gauges, and feeler gauges, including least count. Know hand tools and their correct use, marking out, sawing, filing, drilling, tapping, reaming, and grinding.
251 words, about 1 min08Marine Safety, Pollution Prevention and Environmental Protection
Know the SOLAS, MARPOL, STCW, and MLC frameworks and their main requirements. Understand fire theory: the fire triangle, classes of fire, extinguishing methods, fixed firefighting systems, portable extinguishers, fire detection, and muster drills.
289 words, about 1 min09Engineering Drawing, CAD and Applied Mechanics
Understand orthographic projection, first- and third-angle projection, sectioning, auxiliary views, dimensioning, tolerances, and surface finish symbols. Know isometric and oblique views and the conventions for threads, welds, and gears.
264 words, about 1 min10Mathematics
Revise algebra, indices, logarithms, equations, and inequalities. Study trigonometry: sine, cosine, tangent rules, radian measure, and identities.
232 words, about 1 min11Physics and Applied Sciences
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.
