At 50C the correction factor is 0.923. is there a book that covers all this information regarding fuel calculation, on board ship, ex. With this, the density of fuel oil at tank temperature can be determined using ASTM table or using software most commonly installed on all ships computer. Another reason why we need to calculate or use a correction factor is to ensure that we meet specified requirements of our calibrated reference standards or reference materials. <> endobj its Very Useful and easy understanding article Mr.Ananth. But if you need to use the exact 20.0000 value, you can use the -0.0006 as the correction factor, considering that you will also use it on the UUC side. Determine the distance of the apex of the wedge from the aft bulkhead for obtaining information whether: (1) should a Wedge Formula be used at all (kindly note that a wedge formula is not applicable if: (2) whether the wedge is a regular wedge (which can be checked by comparison with alternative soundings being taken). WebThe API algorithm uses density, temperature, and thermal expansion factor to determine CTL: VCF = /60 = EXP [- 60 (1+0.8 60)] In which: VCF 60 60 = Volume Correction Factor = density at temperature = density at 60F = thermal coefficient of expansion for that type of liquid at 60F = 60.0 (4) Keep Writing.. at last I found what I need as long this time thank to you, yr info.as stars for any one get lost in the tech. WebResults: The ellipsoid formula using correction factor 0.524 underestimates the renal volume by approximately 22.2% with statistical difference compared with the slice summation method (P<.05). If there is a correction factor and you do not know how to apply it, then you did not fully use the actual application of calibration, therefore calibration results become useless in our process application. %PDF-1.5 % The volume of your fuel oil at 100C is 1000m3*1.065 = 1065 m3. Remember that the Correction factor is the result during calibration which is used to offset the error and therefore should be subtracted (or added) on the final value of the balance (UUC) results. Useful consolidation of standard things we all need to remember. Distance over the ground (GPS distance) cannot be used if the slip calculation is required to provide a meaningful figure, using the log distance (the distance the propellor actually moves the vessel through the water) provides an almost true indication of the work actually done by the propellor, with wind and sea state being remaining sources of error. Throughout this calculation it is very important that all distances are in metres. Determine the depth of the wedge at the aft bulkhead of the cargo tank, depth =. 0000196862 00000 n The question above can be answered by using a technique wherein we can adjust a measured value by simply determining what we call a correction factor. 0000002535 00000 n Gases and Compressed Air - Air, LNG, LPG and other common gas properties, pipeline capacities, sizing of relief valves. PMC If you only need to calculate the value of a correction factor between 2 successive points, you can use the Averaging Method. I respect your privacy. 0000011066 00000 n Normally on the BDR, density is given at 15 deg cent. Or, how to adjust the correction factor in order to have the exact value you need? A useful method for assessing differences of compensatory hypertrophy in the contralateral kidney before and after radical nephrectomy in patients with renal cell carcinoma: ellipsoid formula on computed tomography. <>>> I have worked at sea for 43 years, and last 24 years as chief engineer, so very well verse about calculation at end of bunkering. 0000131056 00000 n but make sure to use it also on the UUC result.STD reading = 20.0006 0.0006 = 20.0000UUC Reading = 20.001 -0.0006 = 20.0004, approximately equal to 20.000 based on UUC resolutionError =UUC-STD= 0.0004. 284 0 obj <>stream 0000001472 00000 n 1152 0 obj <>/Filter/FlateDecode/ID[]/Index[1142 24]/Info 1141 0 R/Length 68/Prev 481595/Root 1143 0 R/Size 1166/Type/XRef/W[1 2 1]>>stream If rapid-acting Your email address will not be published. +LK^Xpv)&b. From 2nd reading onwards, you need to add the cumulative amounts released in the withdrawn volumes. Average Daily Traffic (ADT) - The total traffic volume during a given time period (more than a day and less than a year) divided by the number of days in that time period.

Gross Standard Volume (GSV) is the volume of oil including dissolved water, suspended water and suspended sediment but excluding free water and bottom sediment, calculated at standard condition e.g 15. Related Read:Various Methods Used to Minimise Resistance on Ships Hull, Percentage of Slip = X 100%, Engine distance in nautical mile = (Pitch x revolutions per day). xref The actual distance (nautical mile) covered by the ship from noon to noon is measured using the ships log. The Correction Factor formula for calibration is: Correction = (True Value) (Measured Value), 2. Net Standard Volume (NSV) is the volume of oil excluding total water and total sediment, calculated at standard conditions e.g 15. Bolboac SD, Elec FI, Elec AD, Muntean AM, Socaciu MA, Iacob G, Zaro R, Andrie AI, Bdulescu RM, Ignat RM, Iancu M, Badea RI. One of the important skills for a calibration technician to have is to learn how to use the correction factor in a calibration certificate. Anyway it is not so complicated after you have got some experience when you load bunker. Errors can only be detected by performing calibrations. The Fpv Factor at 5 psig is 1.00350 which would make a .35% adjustment on our volume. The volume correction factor for petroleum is really giving me serious concerns. 8 Engine Terms Every Marine Engineer Should Know Part 1, The Ultimate Guide to Fuel Oil Bunkering Process on Ships, 15 Practical Tips For Bunkering and Storage of Fuel Oil On Ships, 14 Terminologies Used for Power of the Ships Marine Propulsion Engine, Various Methods Used to Minimise Resistance on Ships Hull, 8 Engine Terms Every Marine Engineer Should Know Part 2. 2007 Jan;2(1):38-45. doi: 10.2215/CJN.00930306.
