Emission Of Flame Has In The Past Caused Severe Burns To Personnel During A Crankcase Explosion, Despite The Addition Of Flame Traps. Discuss The Procedure In The Event Of Overheating Being Indicated ?

Answer»

As the explosion is an uncontrolled event, then great care must be taken to ensure the safety of the engineers within the engine room. MAN B&W recommend that:

  1. Move away from the crankcase doors immediately
  2. Reduce speed to slow, and ask the bridge to stop
  3. When the engine has stopped, close the fuel supply
  4. Stop the auxiliary BLOWERS
  5. Open the skylight and/or stores hatch
  6. LEAVE the engine room
  7. Lock engine room entry doors and keep away from them
  8. Prepare the fire fighting equipment.
  9. Do not open the crankcase for at least 20 minutes after stopping the engine, and ensure that the oil mist DETECTOR alarm (or bearing temperature monitor) has reset
  10. Stop the LO circulating pump. Shut the starting air, and engage the turning gear.
  11. Locate the “hot SPOT” (source of the oil overheating)
  12. Make a permanent repair to the fault
