volume correction factor calculation formula

Bunker fuel, being a highly valued product, has to be very carefully and accurately calculated for determining the quantity. Traditionally, CTL/VCF values are found in books/tables provided by the American Petroleum Institute, matching the temperature and density to find the CTL/VCF values. The Wedge Formula is to be used only when the oil liquid does not touch all bulkheads of the vessels cargo tank, that is to say the liquid oil lying in small pools among the bottom sediment. Following are 3 important parameters that are most often required to be calculated by marine engineers for record-keeping: Bunker terms to fuel oil in the maritime industry. Throughout this calculation it is very important that all distances are in metres. In practice is the GSV the GOV multiplied by the volume correction factor (VCF) obtained from the appropriate ASTM/IP Petroleum Measurement Tables. There is no statistical difference when using correction factor in the range of 0.664 to 0.686 (P>.05). How is the volume at 15C? many marine engineers has gotten problems in fuel consumption calculations. 0000000016 00000 n Some suppliers use the term weight in vacuum, as in normal condition air give bouncy according to bunker calculation programs formulated by different supplier this weight in vacuum will be .0011% more than in normal condition. 0 Such a method will provide a clearer indication as to the type and nature of the residues on the cargo tank floor as well as provide much clearer indications as to the profile of the residues within the cargo tanks. It is to be noted that in the above formula, the density and volume of bunker fuel should be known at the same temperature. 1 nautical mile is equal to 1852 meters not 1800 m as indicated in the article. Volume correction factors can be used to calculate the volume of a product at base temperature (15C/59F) if you know the density and volume at another temperature. The site is secure. Using Linear Interpolation to Determine Any Value Between 2 Points. The volume correction factor is 1.08 and the new volume can be calculated as.

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. Because the calculations are based on exact numbers, coefficients, and constants, there may be a variance of up to 0.00002 between the computed values below and those found in the traditional tables. 0000226756 00000 n These systematic errors are from: In every correction that we perform, remember that this is not also perfect, measurement uncertainty still exists, therefore, measurement uncertainty should still be considered. The actual distance (nautical mile) covered by the ship from noon to noon is measured using the ships log. Temp diff then will be 30 and density is 0.0204. Gross Weight In Air:Gross Weight in Air is the weight of oil including dissolved water, suspended water & suspended sediment but excluding free water & bottom sediment. Diagnostics (Basel). I see you have great wealth of experience in petroleum measurements, pls I need your help and guidance on this. 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). The volume at 15oC is determined as follows: 5.678 m3(0.9177) = 5.211 m3 at 15oC This demands the marine engineer working onboard ships to do some formula based calculations by considering all those factors and with possible available inputs. Below are the techniques used on how to calculate correction factors in a calibration result that you can use. 0000226406 00000 n I found what I need at this time!! 2020 Jan 13;10(1):41. doi: 10.3390/diagnostics10010041.
