Curriculum
Programme Structure
The programme is structured in 5 modules, listed below in order of study.
01
Basics of preventive maintenance in marine engines
- Fundamental concepts of preventive maintenance and differences between corrective, predictive, scheduled and condition-based maintenance
- Types of marine engines: inboard, outboard, diesel, gasoline, auxiliaries, generators and main engines
- Main components of the marine engine: block, cylinder head, fuel system, refrigeration, lubrication, intake, exhaust and transmission
- Peculiarities of the marine environment: Salinity, humidity, vibration, corrosion, temperature, tilt and prolonged operation
- Hazards of poor maintenance: overheating, power loss, startup failure, high consumption and critical faults
02
Lubrication, refrigeration and fuel systems
- Checking the oil, filters, lubrication pressure, consumption, contamination and periodic substitution criteria
- Freshwater cooling system, saltwater, exchangers, thermostats, pumps and impellers
- Maintenance of sea intakes, water filters, hoses, clamps, anodes and cooling circuits
- Fuel system: tanks, lines, pre-filters, filters, pumps, injectors or carburettors according to type of engine
- Prevention of contamination by water, sediments, microorganisms, air in circuit and degraded fuel
03
Electrical system, starting, loading and engine controls
- Checking batteries, terminals, wiring, masses, fuses, relays, starter motor and control panel
- Alternator, regulator, belts, charging system, voltage measurement and detection of initial electrical faults
- Temperature, oil pressure, tachometer, alarms, indicators and warning signs
- Maintenance of connections against sulfation, humidity, vibration, false contacts and voltage drop
- Basic use of the multimeter to check battery, continuity, charging, polarity and component power
04
Intake, exhaust, transmission and auxiliary mechanical elements
- Checking air filters, turbos, manifolds, vents, hoses and intake restrictions
- Dry or wet exhaust system, exhaust elbow, mixer, silent, hoses, clamps and back pressure
- Maintenance of belts, pulleys, motor mounts, alignment, vibrations and mechanical fixings
- Transmission, inverter, axle, coupling, propeller, horn, cable glands and sealing systems
- Early identification of noise, smoke, vibrations, leaks, burning smell and changes in engine behaviour
05
Marine Engine Preventive Maintenance Project
- Case definition: diesel engine, gasoline, outboard, inboard, auxiliary generator, recreational boat or work boat
- Initial engine diagnosis with hours of use, history, symptoms, electrical system, fuel, lubrication, refrigeration and observable risks
- Design of the preventive maintenance plan with daily, weekly, monthly, seasonal and hourly tasks
- Preparation of inspection checklists, performance tests, consumable replacement and verification of critical systems
- Development of the system of records, spare parts, security, wintering, commissioning and monitoring of incidents
