What instruction covers Safety?
5100.19F
Define 2190 TEP
-2,000 series
-190 viscosity
-turbine extreme pressure
What is the size of L/O sample bottles?
8 oz
What is the shipboard testing frequency for 2190?
1) Daily -- MRGs, Line Shaft Bearings, CPP
2) New Oil -- prior to onload, midpoint, final point, 24 hrs after striking down to storage
tank
3) Prior to each transfer
4) Operating in unusual conditions
5) After equipment casualty
6) Purifier discharge -- 30 min after starting, at least once every 4 hrs
Explain Clear + Bright
Clear = absence of visible particulate matter
Bright = absence of free water
What is the minimum flash point for F-76 and JP-5?
140 degrees F
What is the Auto-Ignition Temperature for JP-5?
, 450 deg F
What is the max allowable for contaminated fuel dilution (CFD) for F-76?
2.64 mg/l
What is the max allowable for fuel water dilution (FWD) for F-76?
40 PPM
What does Cloud Point mean?
temp at which aggregation of molecules becomes apparent as a visible clouding or
haze in the sample
What is Pour Point?
Temp at which fuel will no longer flow; 30 deg F for F-76, 21 Deg for JP-5
What is API/Specific Gravity?
weight of given volume of fuel vs weight of an equal volume of water at 60 deg F
Why do we care about API/Specific Gravity?
-used for fuel distribution
-gas turbine fuel control settling
-F/O purifier settings
After taking F/O sample, how do you determine if the sample is Clear?
Hold the sample in front of good light source. If cloudy, let it sit for 5 min and if still
cloudy heat in water bath to 60 degrees and re-evaluate
What does CCFD stand for?
Combined Contaminated Fuel Detector
When is fuel testing required?
Receipt of fuel, Prior and during transfer, Prior and during use
What is the max allowable CFD for JP-5?
2.0 mg/l
What's the max allowable FWD for JP-5?
10 PPM
What does FSII stand for?
Fuel System Icing Inhibitor?
What's the minimum percentage allowed for FSII?
.03%
What is FSII?
FSII controls icing in fuel systems and growth of microbiological growths in storage
tanks
If you have a sample that is not Clear & Bright, what test is required?
BS&W
What's the allowable BS&W limit?
0.1 % max
How do you reference a GTM/GTG?
aft looking forward
What type of compressor does the GTM have?
16 stage, axial flow compressor
Vane stages 1 through 6 are called what?
Variable Stator Vanes (VSVs)
How many fuel nozzles does the GTM have?
30
