This demands the marine engineer working onboard ships to do some formula based calculations by considering all those factors and with possible available inputs. This correction factor is based on Correction from a calibration result calculated using the equation: From the statement that No measurement is perfect, the correction factor is also just an estimate even though we see it as an exact value of the compensated error (systematic error). If you only need to calculate the value of a correction factor between 2 successive points, you can use the Averaging Method. In this post, I have shared the following: Sometimes, we do not need to use a Correction Factor as long as the errors are very small or negligible and the tolerance limit is very wide, but as a good practice to follow and provides more accurate results, it is better to always implement its use.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'calibrationawareness_com-large-mobile-banner-2','ezslot_11',127,'0','0'])};__ez_fad_position('div-gpt-ad-calibrationawareness_com-large-mobile-banner-2-0'); Thank you for reading my post.

A very nice and useful post which should come useful to any engineer who has to handle bunkers. Thanks. 1 nautical mile is equal to 1852 meters not 1800 m as indicated in the article. 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. There is no statistical difference when using correction factor in the range of 0.664 to 0.686 (P>.05). An official website of the United States government. 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. (Calculation of bunker fuel quantity in weight involves many factors to be considered making it more complex.). Water layer existing as a separate phase in the tanks, normally detected by water-paste or interface detector and usually settled at the bottom of the cargo tankdepending on relative density of the cargo. This site also participates in other affiliate programs and is compensated for referring traffic and business to these companies. The site is secure. The volume of fuel oil at tank temperature for the corresponding tank sounding is thus measured using tank capacity table, which gives the actually sounded volume. As such, the CTL/VCF value is computed using the observed temperature and density of a liquid. These two numbers will be computed with the coefficient of thermal expansion at 60F () based on the selected commodity and return the CTL/VCF Value. If rapid-acting The volume at 15oC is determined as follows: 5.678 m3(0.9177) = 5.211 m3 at 15oC The total revolutions of the propeller from noon to noon is obtained using the revolution counter. 0000003920 00000 n Furthermore this wedge formula calculation makes the enormous assumption that any liquid found in a cargo tank is in the form of a regular wedge shape with its base at the aft bulkhead of the cargo tank. @Mueen: This is great. The marine engine efficiency is usually determined using the SFOC. The total volume of material measured in the tank including cargo (oil or chemical), free water (FW), entrained sediment and water (S&W), sediment and scale as measured at observed temperature and pressure. %PDF-1.5 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. The volume of your fuel oil at 100C is 1000m3*1.065 = 1065 m3. 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. Using the calculator below, enter the Temperature in degrees Fahrenheit ( F ), and the Density in Degrees API. Every ship is provided with a tank capacity table in which each tank capacity in volume is marked against the successive levels of sounding/ullage with correction factors under various trim and heel conditions of the ship. Mostly, the fourth engineer will be the deputy of the Chief engineer for receiving bunker & measuring the bunker quantityfor maintaining records. One of the most important skills when interpreting and using a calibration result is the capability to understand and calculate Correction Factors. endobj A simple technique that we must learn in order to improve our measurement results and in effect improving also our process.

Net Standard Volume (NSV) is the volume of oil excluding total water and total sediment, calculated at standard conditions e.g 15. Because of that formula used by most engineers when receiving bunkers. bunkering, port to port consumption, ordering fuel, regulations etc. Using Linear Interpolation to Determine Any Value Between 2 Points. So if there is a conversion of a bunker tank from heavy fuel to light fuel calibration table must also be changed because for a given mass heavier fuel will acquire less volume and lighter one will acquire more volume. 0000130230 00000 n 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. But there are some essential parameters which cannot be read directly through any instrument as they depend on a number of dynamic factors. Shear-Wave Elastography Variability Analysis and Relation with Kidney Allograft Dysfunction: A Single-Center Study. Now often referred to as apparent mass, and can be converted to mass by the application of an air buoyancy correction (Table 56 = weight correction for oils). WebMost gas meters measure the volume of gas at existing line conditions of pressure and temperature. that would impact the accuracy of the volume calculated from the sounding. Just a thought. Accessibility Bunker If not, the horsepower can also be calculated using engine rpm and average pump fuel index with the aid of engine characteristic curve of various sea trials which is supplied by the manufacturer. Stated Hi, Just call me Mariners friend, engage for 26 years in petroleum survey and bunker survey.
