1. What is MMFOL?
    Major F/O Leak
  2. What are the indications of MMFOL?
    • Spray or leak of F/O in affected area.
    • Severe pressure drop or total loss of F/O pressure.
    • Main engine/SSDG stops.
    • F/O header pressure drops.
    • Smell of F/O in space.
  3. What are the Controlling Actions of MMFOL?
  4. NOTE: When can the combustion air shutoff be used?
    Only if the electronic and mechanical E-stops fail
  5. NOTE: What happens to the engine if it’s stopped without allowing time for cooldown?
    May cause damage to the engine
  6. NOTE: When is the best time to bar over the engine after a MLLOP casualty?
    At earliest opportunity
  7. NOTE: What happens in the event that both online SSDG’s were operating in the same space and F/O service tank is secured?
    May cause the loss of other SSDG on unaffected bus (sharing the same service tank).
  8. WARNING: What actions to take prior to activating AFFF sprinklers?
    Ensure sprinkler isolation valves are open
  9. WARNING: What should not be sprayed with AFFF or water when flushing oil into the bilge?
    Electrical equipment
  10. What are the Immediate Actions of the Rover/CRT?
    • “EOOW, Major F/O leak _ MMR/Aux _ (size and location).”
    • MMR
    • Verify _ main engine clutch has automatically disengaged. If not, manually disengage/dump the air to _ main engine clutch. Report, “_ main engine clutch disengaged.”
    • Stop/secure F/O transfer pump/purifier. Report, “F/O transfer pump/purifier stopped/secured.”
    • Trip desalination plant.
    • AUX
    • Shut F/O service tank suction and return valves.
    • “Manned and ready.”
    • Shoulder EEBD
    • Isolate F/O leak. Report, “F/O leak isolated.”
    • Activate bilge sprinkling system for a minimum of one minute until all bilge surfaces are adequately covered.
    • “EOOW, bilge sprinkling system activated for _ minutes and secured.”
    • Man firefighting equipment and flush F/O into the bilge and cover with AFFF.
    • “EOOW, Firefighting equipment manned, flushing F/O into the bilge and covering with AFFF.”
    • “F/O flushing into the bilge and covered with AFFF.”
  11. What are the Immediate Actions of the PACC?
    • MMR
    • E-stop affected shaft
    • Place affected shaft in trailing mode by resetting shaft E-stop and selecting “TRAILING”.
    • E-stop _ main engine.
    • Ensure _ main engine clutch disengage.
    • Stop F/O service pump.
    • Shut affected MMR F/O service tank suction and return valves.
    • “EOOW, Thrust control shifted to CCS. _ main engine stopped, clutch disengaged, _ shaft trailing. ECS is in trailing mode.”
    • Stop/secure L/O transfer pump/purifier. Report, “F/O transfer pump/purifier stopped/secured.”
  12. What are the Immediate Actions of the EPCC?
    • E-stop affected _ SSDG. Ensure GCB opens.
    • Start STBY SSDG. Report to EOOW when it has started and is ready for electrical load. Close GCB as ordered by.
    • E-stop SSDG on unaffected bus affected by the securing of fuel. Ensure GCB opens.
    • “EOOW, _ SSDG E-stopped, _ SSDG placed online. Electrical plant configuration is _, with ship’s load of _ amps and _ kw on port/stbd bus.
  13. What are the Immediate Actions of the EOOW?
    • IMC, “Major F/O leak in (space). CRT, lay to (space).”
    • “OOD, Major F/O leak _ MMR/AMR, request condition 2 DC set.”
    • MMR
    • “OOD, Major F/O leak _ MMR/AMR, _ main engine stopped and _ shaft trailing. Thrust control shifted to CCS.”
    • AUX
    • Order EPCC to close STBY GCB.
    • “OOD, Major F/O leak AUX _; stopped _ SSDG. Electrical plant configuration is _.”
    • Order space to man AFFF.
    • “OOD, Major F/O leak in _ MMR/AUX _ is isolated. F/O in _ MMR/AUX _ is flushed into the bilge and covered with AFFF.
