LOQM

  1. How do you do a BS&W for 2190?
    • Fill 2x 100ml tubes with 50% sample and 50% solution
    • Spin at 1500rpm for 30 minutes (+1 min to get to 1500rpm).
  2. Where do results go?
    • Results get logged in the LOQM log
    • SAE 40 also goes into the Kittiwake log
    • Sat samples go back to the sump.
  3. What is the design capacity of the Lube Oil Purifier?
    • 8.3 gpm
    • 50 psig
  4. Describe MRG Lube Oil Sequencing.
    • When running with only the attached pump online, the lead pump starts on low at 22 psi, when system pressure drops to 20 PSI, the lead pump starts on high,
    • when system pressure reaches 18 PSI the lag pump starts on high speed, so both
    • pumps start on high at 18 PSI.
  5. What are the logics for MRG L/O?
    • Normal - 17-26PSI
    • Lead pump start LOW - 22 PSI
    • Lead pump goes high - 20 PSI
    • Emergency start in high - 18 PSI
    • Alarm - 17 PSI
  6. When do we take L/O samples?
    • daily while operating
    • prior to transfer
    • weekly from storage tanks
    • every 4 hours while purifying
    • after starting systems (30 minutes)
  7. Where do L/O results go?
    • Results get logged in the LOQM log
    • SAE 40 also goes into the Kittiwake log
    • Sat samples go back to the sump.
  8. What is a hot bath / water bath and why is that required?
    • A water bath is to heat L/O to 120 deg F to remove cloudiness in fuel caused by low temperatures.
    • If the sample is 120 deg F and is still cloudy, that is an indication of water..
  9. What NSTMs do L/O apply?
    • NSTM 262 - MRG 2190, LSB 2190 and MPDE
    • NSTM 245 - SSDG SAE 40
    • What is an efficiency sample?
    • Inlet and Outlet samples are drawn
    • Outlet must be better or equal to the inlet.
  10. What is shooting the bowl?
    • It is sending potable water horizontally through the bowl to clean out all of the sludge that builds up during purification.
    • This occurs every 4 hours and the sludge goes to the sludge tank underneath the purifier.
    • Take a sample 30 minutes after shooting the bowl.
  11. Is there a written requirement to purify MRG 2190 like there is to purify CPP 2190 (the CPP requirement is a minimum of 4 hours a day)?
    • No there is not
    • GBY’s requirement comes from CHENG.
  12. What do we do with 2190 Lube Oil that fails C&B?
    • Renovate it via the purifier and settling tank (aka batch purification).
    • We send it to the settling tank and heat it there to separate the water and oil before sending it through the purifier.
  13. How often do we check sump levels for MPDEs and LSBs?
    Daily while operating.
  14. What are testing parameters for SAE 40?
    • Fuel dilution: change out oil if result is 3.5% or greater
    • Viscosity: Oil change is not required between 108-165 cSt
  15. Why does viscosity matter?
    • Low viscosity = quick flow
    • High viscosity = slow flow
  16. What is a hot bath / water bath and why is that required?
    • A water bath is to heat L/O to 120 deg F to remove cloudiness in fuel caused by low temperatures.
    • If the sample is 120 deg F and is still cloudy, that is an indication of water..
  17. How often do we check sump levels for MPDEs and LSBs?
    Daily while operating.
  18. What are testing parameters for SAE 40?
    • Fuel dilution - change out oil if result is 3.5% or greater
    • Viscosity - Oil change is not required between 108-165 cSt
  19. When are L/O samples required?
    • Daily when operating – MPDE, LSB
    • Weekly – CPP

    C/B
  21. What is the criteria for 2190 with a non-purifiable sump?

  23. What is TB?
    Total base number

    262
  25. What NSTM covers CPP and Hydraulic Systems?
    245
  26. MPDE: What is the maximum/alarm L/O inlet temperature?
    140 F
  27. MPDE: What is the L/O inlet pressure?
    70-85 psi
  28. MPDE: What is the L/O inlet pressure alarm?
    58 psi
  29. MPDE: L/O standby pump will start at what pressure?
    65 psi
  30. MPDE: What is the Engine shutdown L/O pressure?
    50 psi
  31. MPDE: What is the L/O systems temperature?
    100-150F

    14-30 psi
  39. What is a SNOK?
    • Standard Notes For Oil King
    • Consist of adhering to Clean Water Act,
    • CO’s Permission prior to pumping,
    • Leak down tanks must be pumped down and monitored,
    • Oil King will do initial alignment and this must be second checked by an Officer,
    • Station overflow watches,
    • Communication is key.
    • Fuel oil service tanks shall be filled immediately after being taken off suction.
    • Prior to being placed on suction, tank must be allowed sufficient time to settle, then checked for the presence of water IAW NSTM Chapter 541.
    • When a fuel oil tank is open, ensure there is no smoking or naked lights in the vicinity of the open tank.
    • The use of open lights, electrical or mechanical apparatus capable of sparking, shall not be permitted within 50 feet of a fuel hose, open tank, open sounding tube, vent, or any area where fuel oil or fuel oil vapors may be present.
    • An oil spill containment kit shall be readily available prior to and during all refueling operations.
