  1. MK1 POWER POINT KURT SCHULZE

  2. AUX EQUIPMENT FOR SMALL HEAT EXCHANGER, USE A NYLON BRUSH ON THE END OF A NON METALLIC ROD TO CLEAN EACH TUBE MANUALLY

  3. AUX • SHELL AND TUBE HEAT EXCHANGER- USE A HYDROSTATIC TEST NSTM CHAPTER 254

  4. AUX • CORROSION OCCURS IN TUBING OF HEAT EXCHANGER RESULTING FROM CURRENT FLOW BETWEEN DISSIMILER METALS

  5. AUX • HEAT EXCHANGER ARE DEVICES THAT TRANSFER HEAT FROM ONE FLUID TO ANOTHER.

  6. AUX • CORROSION OCCURS IN TUBING OF HEAT EXCHANGER RESULTING FROM CURRENT FLOW BETWEEN DISSIMILER METALS.

  7. AUX • SOFT FOULING INCLUDES FOREIGN MATTER SUCH AS SAND, MUD, OIL, SLIME AND SOFT BODIED MARINE LIFE THAT DOES NOT ADHERE STRONGLY TO THE TUBES OF A SHELL AND TUBE HEAT EXCHANGER.

  8. AUX • CHECK TO MAKE SURE THAT NO MORE THEN 10% OF THE TUBES ARE PLUGGED.

  9. AUX • FOULING,SCALING, AND BLOCKAGE IN THE TUBES OF A SHELL AND TUBE HEAT EXCHANGER REDUCE HEAT TRANSFER.

  10. AUX • PLATE TYPE HEAT EXCHANGER, ENSURE THE PLATES ARE ASSEMBLIED IN THE EXACT ORDER IN WHICH THEY WERE REMOVED.

  11. AUX • CHECK TO MAKE SURE THAT NO MORE THEN 10% OF THE TUBES ARE PLUGGED.

  12. AUX • A FIN AND TUBE HEAT EXCHANGER IS AN AIR COOLED CONDENSER USED IN THE AC&R SYSTEMS. THE FINS INCREASE SURFACE AREA AND AID IN TRANSFERRING HEAT

  13. AUX • HEAT EXCHANGER MAINTENANCE NSTM CHAPTER 254

  14. AUX • SHELL AND TUBE TYPE HEAT EXCHANGER ARE THE MOST COMMONLY USED IN THE COAST GUARD.

  15. AUX • THE TWO TYPES OF AUXILIARY BOILERS: • 1. WATERTUBE BOILERS • 2. FIRETUBE BOILERS

  16. AUX • THE DISADVANTAGES OF A WATERTUBE BOILER THAT THEY ARE EXPENSIVE TO BUILD.

  17. AUX • LATENT HEAT IS???? • CONDENSATION

  18. AUX • THE VAPOR THAT IS PRODUCED IN THE FIRST STAGE FLASH CHAMBER PASSES THROUGH THE MESH SEPARATOR. THE VAPOR IS CONDENSED ON THE OUTSIDE OF THE FIRST STAGE CONDENSER TUBES TRANSFERRING ITS LATENT HEAT TO THE SEAWATER FEED WITHIN THE TUBES (EVAPORATOR)

  19. AUX • THE 3 WAY SOLENOID-TRIP VALVE ON THE DISTILLATE LINE.

  20. AUX • CLEANING A FLASH TYPE EVAPORATOR THE COLOR INDICATOR IN THE ACID POWDER DENOTES THE FOLLOWING: • YELLOW= DISSOLVED AND HEATED • LIGHT GREEN= ACID IS 85% CONSUMED, VERY WEAK

  21. AUX • HYDRAULICS USE?? • KINETIC ENERGY

  22. AUX • THE POSITIVE DISPLACEMENT PUMP DESIGN IS TYPICAL OF A HAND PUMP.

  23. AUX • CAVITATIONS OCCUR WHEN PUMP INLET VACUUM GETS HIGH ENOUGH TO PULL ENTRAPPED AIR OUT OF THE HYDRAULIC FLUID. CAVITATIONS OCCUR WITH AS LITTLE AS 5 INCHES HG.

  24. AUX • HYDRAULIC MOTORS INCLUDE= • 1. GEAR MOTOR • 2. VANE MOTOR • 3. PISTON MOTOR

  25. AUX • WHAT ARE 3 TYPES OF ACCUMULATORS IN HYDRAULIC SYSTEMS • 1. SPRING LOADED • 2. WEIGHT LOADED • 3. GAS CHARGED

  26. AUX • NEVER USE ABRASIVE OR METAL TOOLS OR WIRE BRUSHES FOR CLEANING TUBES!!!!!!!!!!

  27. AUX OWS • RED LIGHT WHEN POWER IS ON. • AMBER LIGHT WHEN OIL IS BEING DISCHARGED • GREEN LIGHT WHEN WATER IS BEING DISCHARGED

  28. AUX • TROUBLESHOOTING AN OWS • SYMPTOM- DISCHARGE WATER THROUGH THE OIL OUTLET VALVE • DIRTY OIL SENSING PROBE- DEFECTIVE PROBE AMP RELAY • DEFECTIVE OIL SENSING PROBE

  29. AUX • HYDRAULIC FORMULA- • AREA=FORCE/PRESSURE

  30. AUX • TORQUE IS NOT FOUND ON THE NAME PLATE DATA LABEL OF A ?? • MOTOR

  31. AUX • SOFT FOULING INCLUDES FOREIGN MATTER SUCH AS SAND, MUD, OIL, SLIME AND SOFT BODIED MARINE LIFE THAT DOES NOT ADHERE STRONGLY TO THE TUBES OF A SHELL AND TUBE HEAT EXCHANGER.

  32. AUX • THE TEMPATURE AT WHICH WATER BOILS IS CALLED • THE BOILING POINT OR SATURATION TEMPATURE

  33. AUX • THE SQUIRREL CAGE BLOWER RECIEVER A HIGH QUANITY OF AIR (FOR ITS SIZE) FOR COMBUSTION.

  34. AUX • BOILERS HAVE AN INLET FUEL STRAINER ARE PROVIDED TO PREVENT CONTAMINETS FROM ENTERING THE FUEL OIL PUMP.

  35. AUX • THE BLOWER ASSEMBLY MUST BE KEPT CLEAN AN EXCESSIVE BUILDUP OF DIRT AND GRIME CAUSES AN INADEQUATE AMOUNT OF AIR SUPPLY FOR COMBUSTION AND RESULTS IN A DIRTY, SMOKY FLAME.

  36. AUX • FEEDWATER TESTING-ALKANITY TESTING (PH)

  37. AUX • -3 EXAMPLES OF COALESCING MEDIA ARE: • METAL PLATES • REPLACEABLE FILTERS • BRUSCH ASSEMBLIES

  38. AUX-HYDRO • HYDRAULIC FORMULA- AREA=FORCE/PRESSURE

  39. AUX-HYDRO • TWO TYPES OF STRAINERS USED IN A HYDRAULIC SYSTEM ARE: • WIRE MESH STRAINER • EDGE DISK STRAINER

  40. AUX-HYDRO • COMMON FAILURE OF HYDRAULIC MOTORS IS BREAKAGE OF THE OUTPUT SHAFT WHICH IS CAUSED BY EITHER SHAFT MISALIGNMENT OR LOADS WITH EXCESSIVE TORQUE

  41. AUX-HYDRO • BEFORE WORKING ON A HYDRAULIC SYSTEM • SECURE AND TAG OUT ALL SYSTEMS BEFORE WORKING ON THEM IN ACCORDANCE WITH THE COMDINST 9077.1-EQUIPMENT TAG OUT PROCEDURES

  42. AUX-HYDRO • WHILE WORKING ON A HYDRAULIC SYSTEMS • NEVER WORK ON A RUNNING SYSTEM, EXCEPT FOR MINOR PRESSURE ADJUSTMENTS(e.g SETTING THE PRESSURE RELIEF VALVE)

  43. AUX-HYDRO • AFTER WORKING ON A HYDRAULIC SYSTEM • BEFORE STARTING ANY HYDRAULIC SYSTEM, ALWAYS FOLLOW STARTING PROCEDURES AND VALVE ALIGNMENT IN ACCORDANCE WITH UNIT-SPECIFIC INSTRUCTIONS AND MANUFACTURERS TECHNICAL PUBLICATIONS

  44. TRAINING • IN PRELIMINARY PHASES “WALK THROUGH” ARE IMPORTANT FOR IMPARTING KNOWLEDGE OF CASUALTY CONTROL PROCEDURES

  45. TRAINING • AS THE TEAM LEADER ONE OF THE MOST IMPORTANT ISSUES FOR YOU TO ACCOMPLISH BEFORE THE DRILLS TAKE PLACE IS A SAFETY WALK THROUGH.

  46. TRAINING • REQUEST CREW TO CONDUCT A SELF CRITIQUE OF THE OVERALL DRILL AND ITS OUTCOME. ASK FOR INPUT AND FEEDBACK

  47. THE ONBOARD TRAINING TEAMS(OBTT) SHALL BE USED TO ASSESS WATCH STATION PERFORMANCE FOR ALL DRILLS AND EXERCISES

  48. TRAINING • SAFETY OBSERVER • ENSURES THAT PROCEDURES ARE IN COMPLIANCE WITH APPLICABLE SAFETY PRECAUTIONS AND REQUIREMENTS

  49. TRAINING • TRAINING TEAM EVALUATION FORMS SHALL BE KEPT AS PART OF THE SHIPS TRAINING RECORDS AND BE REVIEWED PERIODICALLY TO AID IN IMPROVING THE TRAINING PROCESS

  50. TRAINING • (BECCE)- THE GREEN, AMBER, RED(G.A.R.) MODEL IS USED TO ADDRESS MORE GENERAL RISK CONCERNS WHICH INVOLVE PLANNING OPERATIONS, OR REASSESSING RISKS AS WE REACH MILESTONES WITHIN OUR PLANS.
