You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to calculate the mass or volume given a certain heating value. A list of some common oil density Oil, As per my understanding it is Days Run or GPS distance nowadays.. Log distance will give huge variations in the actual slip. You will also get the fuel oils CCAI, Specific energy and the normal m of air per kg of fuel for stoichiometric combustion. Anchored (i.e. 1 gallon of propane = 91,452 Btu. Then, use the light blue line in the Fuel oils volume correction figure ([emailprotected] T/[emailprotected]C). The Chief Engineer is responsible for checking the fuel quantity bunkered. Does fuel density change with temperature? Very usefull topic. What is the volume correction factor for fuel oil density? Position, Arrival and Departure reports in the companys reporting infrastructure for ships are the primary means of reporting MRV-related data, including fuel consumption, transport work, and other voyage-related data. at 45 deg C. Using ASTM TAB. Reeds Naval Architecture for Marine engineers. Bunker oil is generally any type of fuel oil used aboard ships. With these two values applied to the formula above SFOC is calculated? For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters. Lighterage location (all lines cast off from lighter vessel/anchor aweigh), Related Read:7 Important Points For Safe Lightering Operations On Ships. 54B and ASTM TAB 56 your actual metric tons received are = 878.168 surveyors calculation. Residual fuel oil with density = 1014 kg/m 3 at 15 C and a kinematic viscosity of 1000 cSt at 50 C. Diluent with density = 850 kg/m 3 at 15 C and a kinematic viscosity of 3.4 cSt at 50 C. In order to obtain a viscosity of 600 cSt for the blended product, it is needed to mix 95,1 % mass of residual fuel oil and 4,9 % mass of diluent. Volume correction factorsdiesel, bio-diesel and diesel blends. Substance densities currently available for the oil converter : Crude oil, Diesel Fuel Oil, Fuel oil, Furnace Oil, Gas oils, Oil (petroleum) If you have any suggestions for this oil conversion tool, or have any additional oil density figures that you wish to be included, please contact me . The formula (Corrected Density = Density at 150C X [1 {(fuel temp (0C) 150C) X 0.00065}]) should be used to obtain the corrected density at the recorded fuel temperature. How do you calculate the density of fuel oil? - Heimduo Fuel oil is a kind of product with a lot of classes and under classes as well as varying specifications in different markets. Positive slip is influenced by various reasons such as fouled bottom or hull part which offers resistance to the movement of the ship, environmental factors such as water current and wind against the ship direction. Fuel Cost Calculator An example of data being processed may be a unique identifier stored in a cookie. T =temperature of oil in bunker tanks in degree Celsius, Your email address will not be published. Why Nautical Mile and Knot Are The Units Used at Sea? For emission sources that are not fitted with Flow meters or when the Flow meters are not operational, bunker fuel tank monitoring on board is to be done. Oil converter and calculator (Converting oil between volume and weight p = is density at 15C, in kilograms per cubic metre, ex. So, plugging these values in the formula above, we get: mass = 890.13 1 0.003785411000 mass = 3.369511000 mass = 0.00336951 tonne (answer) With this parameters calculate the volume of the bunker to be received in each tank as per bunkering plan and note down the final sounding level of each tank after bunkering using the capacity table for the ease of stopping & change over to next tank. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. When the slip is negative, there is nothing about favourable current, only wind or some unknown for me circumstances may affect. An Arrival report for a specific Port or offshore location must be followed by a Departure report from the same Port or offshore location. At 200C the correction factor is 0.859. TCD = (Fuel Oil density @ 15C) x {1- ( (T-15) x 0.00064)} With all of the above calculations using provided data, it's very common that the bunker barge who supplies the fuel oil will not care for any surveyor to manipulate figures. Thank you for this insightful comment. Fuel Calculator | Nautical Fuel Consumption Calculator - Dan-Bunkering Certificates of calibration are to be issued post these checks and retained on board. How does oil density change with temperature? When you enter these values, the molar mass is . This is one of them. Actually, there is no black oil property that. Density of Diesel Fuel is 850 kg/m 3. The slip may be negative if the ship speed is influenced by following sea or wind. These two numbers will be computed with the coefficient of thermal . Used formulas are listed below the calculator. Continue with Recommended Cookies. The formula used to calculate the Temperature Corrected Density is: = (Density of Fuel Oil @ 15C) x [1- {(T-15) x 0.00064}] A written record is to be made of the results of these soundings and free water checks.

In ships engine room, a number ofgauging instruments displayvarious important parameters such as level, pressure, temperature etc. First arrival in port means, the first time (for a specific port/location) that the vessel is: All fast to a wharf/buoy moorings / SBM (if berthing directly, without anchoring), or Related Read:Malpractices In Bunkering Operations Seafarers Should Be Aware Of. It is to be noted that in the above formula, the density and volume of bunker fuel should be known at the same temperature. Oil Density Standing (1947) First-stage separator gas specific gravity Stock-tank oil specific gravity Solution gas-oil ratio at bubble point pressure Gas Gravity (sp. I have a suggestion to you, that you can add the calculation for bunker requisiton, co2 bottle weight measurement, scba time duration calculation,etc. Since the density of fuel varies greatly depending on temperature, the volume of actual fuel in the tank varies, and therefore the weight varies. Metal, Using the API to specific gravity conversion calculator: API = (141.5 / 0.7508) - 131.5 = 56.98 API Classification of API gravity brought up to anchor) outside port limits, or ASTM No.1 is a light distillate intended for use in burners of the vaporizing type in which the oil is converted to a vapor by contact with a heated surface or by radiation. A calculation table has been provided for this purpose in the excel worksheet. Hours underway from the last berth at the port of departure to the first berth at the port of arrival is calculated from the departure and arrival times (GMT) and dates (GMT) recorded in Departure and Arrival reports. Useful consolidation of standard things we all need to remember. Use the correct motor oil. Distances travelled through the water are also to be reported in Position and Arrival reports and are to be taken from the (water) speed log. Oil Density Glaso (1980) First-stage separator gas specific gravity Stock-tank oil specific gravity Solution gas-oil ratio at bubble point pressure Gas Gravity Oil Gravity Producing GOR Temperature Pressure Calculate Oil Density N.B. Actually, Im a fresh graduate frm the Petroleum Training Institute, Nigeria. The author and Marine Insight do not claim it to be accurate nor accept any responsibility for the same. Then, use the light blue line in the Fuel oils volume correction figure (Density@Observed T/Density@15C). With the difference in readings, the volume of fuel consumed is obtained. In addition to Position, Arrival and Departure reports, other relevant periodic reports including Noon Reports, Monthly Reports, and Quarterly Reports are to be filled as per the formats in the companys reporting infrastructure for ships. The volume correction factor for petroleum is really giving me serious concerns. How do you calculate fuel oil consumption?
