Dual Fuel Marine Engine Operation, Control and Safety

After successfully passing the training program, the trainee should:

• explain the basic concept of dual-fuel marine propulsion and the operational reasons for using LNG/gas fuel on board ships;
• describe the principal properties and hazards of natural gas, methane and LNG relevant to shipboard operation;
• identify the principal ME-GI gas-system components, including gas block, gas injection valve, window valve, purge valve, blow-off valve and sealing-oil-related arrangements;
• explain the function of FGSS, LNG storage tank, vaporizer, gas compressor/high-pressure supply arrangement and Gas Valve Unit/Gas Valve Train;
• describe diesel mode, gas mode, gas start, gas stop, gas shutdown and fuel-mode changeover;
• explain the basic architecture of ME-DF-ECS, including ECU/CCU, SPCU/SACU, SPSU/SCSU, MPC/Triton and DASU units at familiarization level;
• apply safe working principles around high-pressure gas, cryogenic fuel, double-wall piping, ventilation ducts and gas-detection systems;
• interpret selected ME-GI gas-channel alarms and identify probable operational or component-related causes at a basic troubleshooting level;
• respond correctly to gas detector alarms, suspected gas leakage, abnormal combustion indications, gas trip and emergency shutdown scenarios;
• demonstrate component-identification skills using simplified ME-GI and FGSS diagrams;
• demonstrate a safety-oriented professional attitude during case studies, checklist exercises and oral/practical assessment.

Entry Standards for admission to the training course are:

• Certificate of Competency, Education Certificate or Certificate of Proficiency, according with the requirement of the specific field as defined by international or national regulations; recommended technical background: basic marine diesel engines, engine-room watchkeeping, alarms, fuel systems and safety procedures.
• Seamen’s book or Civil passport or ID.
