Maskinbefal study plan

Map the propulsion plant: trace the energy flow from fuel tank to propeller shaft for a two-stroke main engine and a four-stroke auxiliary engine, and label every heat exchanger and pump on your own hand-drawn diagram.

Explain the two-stroke scavenging and uniflow exhaust process and the four-stroke valve timing sequence in writing, naming the components that fail most often in each.

Calculate indicated and brake power, specific fuel consumption and mechanical efficiency from a set of made-up indicator diagrams and fuel-flow figures, showing every step.

Describe starting-air, fuel-injection and cylinder-lubrication systems well enough to explain what happens in the first 60 seconds after a main-engine start command.

Describe the function and operating limits of the main auxiliary systems: cooling water, lubricating oil, compressed air, fuel treatment and bilge/ballast pumping, and state what alarm would appear first if each failed.

Diagnose five written fault scenarios (high exhaust temperature, low lube-oil pressure, scavenge fire, fuel-oil viscosity fault, air-start failure) by listing symptoms, probable causes and the first three corrective actions in order.

Explain the procedure and safety precautions for starting, paralleling and stopping an auxiliary diesel generator, including blackout recovery.

Outline a weekly and monthly planned-maintenance routine for the main engine and its auxiliaries, naming the checks and the records kept.

Explain how to take and interpret indicator cards and pressure readings, and state what abnormal card shapes reveal about injection timing and exhaust timing.

Describe the correct response to a crankcase explosion, scavenge-space fire and exhaust-gas boiler fire, including the isolation and fixed-system actions and the reasons for each step.

Explain the safe isolation and permit-to-work sequence before opening a fuel line, a sea-water line and an electrical motor, naming the lock-out and tag-out steps.

Plan a pump overhaul from isolation to recommissioning, listing the tools, spares and checks at each stage.

Explain the six degrees of freedom, the meaning of initial metacentric height and the effect of free surface on stability, using a worked example with added weights.

Calculate a ship's final draught and trim after loading or discharging a weight at a known position, showing the moment calculation.

Interpret a hydrostatic table and a KN or GZ curve to determine whether a given loading condition meets the required intact-stability criteria.

Identify the structural members of a transverse frame and explain how hull stresses (hogging, sagging, racking, panting) arise and are resisted.

Compare five ship types (bulk carrier, tanker, container ship, Ro-Ro and general cargo) by cargo-handling arrangement, structural features and typical stability issues.

Explain the main switchboard, generator protection (reverse power, overcurrent, under-voltage, frequency) and preferential tripping, and describe the actions taken after a total blackout.

Describe the function and testing of the emergency generator, emergency switchboard and battery-backed emergency lighting, and state the statutory test interval you must verify in the ship's records.

Explain how a fire-detection loop, a fixed CO2 or foam system and a fire pump are arranged and tested, and what must be checked before releasing CO2 into a space.

Outline the muster-list duties and the sequence of actions for fire, abandon-ship and man-overboard drills, including the communications chain.

Explain the purpose of the shipboard oil pollution emergency plan and the safety-management-system drill records as they relate to emergency preparedness.

State the discharge requirements of MARPOL Annex I (oily water, sludge, 15 ppm equipment) and Annex IV (sewage) and Annex V (garbage), including the record books and retention periods for each.

Explain the operation of the oily-water separator and the 15 ppm alarm, and describe the actions required when the alarm sounds during discharge.

Identify the Annex VI requirements that affect engine-room operation: sulphur limits, fuel-oil changeover procedure, NOx tiers and the ozone-depleting-substance record.

Describe the ballast-water management convention requirements for exchange, treatment and record-keeping, and the consequence of non-compliance at a port state inspection.

Explain how to complete an oil record book entry correctly and list the common deficiencies found during inspections.

Explain the STCW requirements for certification, rest hours and watchkeeping, and calculate a rest-hour record that meets the minimum requirements over a seven-day period.

Describe the master's authority and the obligations that pass to the officer of the watch, including when to call the master.

Outline the survey and certification regime (class, statutory, port state control) and explain what a certificate of class and a safety-management certificate each attest to.

Explain the content and use of the muster list, the emergency instructions and the standing orders for the engine-room watch.

Identify the pollution-reporting and casualty-reporting obligations that fall on the officer of the watch.

Explain how fatigue, complacency and poor communication contribute to engine-room incidents, and describe three concrete countermeasures you would apply on watch.

Describe a structured handover between watches and a structured briefing before a hazardous job, listing the information each must contain.

Explain the purpose of the safety-management system, the near-miss reporting process and how a non-conformity is closed out.

Review your notes from weeks 1 to 7 and write a personal list of the ten weakest areas, then answer practice questions on each until you score consistently.
