Density @ 15*C 0.9903 = 0.9870
(see the above picture you need to interpolate if any different numbers on both columns). (Quick formula with reducing factor for WCF is Density @ 15*C – 0.0011 = 0.9903 – 0.0011 = 0.9892).
How are bunker prices calculated?
The BAF is calculated
by multiplying the so-called ‘trade factor’ by the fuel price
. The fuel price will be the same for all trades and is calculated as the average bunker price in key supply ports around the world over a period said to be “typically” three months.
How is bunkering calculated?
From this you will get the total volume of bunker. Go to your sounding table go to the page of your particular tank which you are planing to take bunker, find out the volume by considering the trim. There you will get the final ullage or sounding of your tank.
How is fuel oil density calculated?
Measuring and Reporting Fuel Oil Consumption
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. A calculation table has been provided for this purpose in the excel worksheet.
How is engine distance calculated?
Engine distance =
Pitch X RPM X 60 X 24 / 1852
.
What is GSV in shipping?
Gross Standard Volume
(GSV) – The total volume of all petroleum liquids and sediment and water, excluding free water, corrected by the appropriate volume correction factor (Ctl) for the observed temperature and API gravity, relative density, or density to a standard temperature such as 60°F or 15°C and also corrected ...
Does oil volume change with temperature?
Variations in lubricating oil density are shown as function of temperatur, together with volume correction factors. ... To be sure you have used the correct figure for correction factors, the easy rule is that
the volume increases with increasing temperature
.
What is meant by bunker charge?
Abbreviation for “Bunker Charge.” An extra charge sometimes added to steamship freight rates; justified by higher fuel costs. Also known as
Fuel Adjustment Factor
or FAF.
Who should pay Bunker Adjustment Factor?
The Bunker Adjustment Factor (BAF) is an
additional charge levied on the shippers
to compensate for fluctuations in the price of the ship’s fuel. Also referred to as bunker surcharge, it is tied to the price of Brent crude oil, a major benchmark for worldwide oil prices.
What is bunker fuel used for?
Maritime vessels use bunker fuel to power their motors, but depending on your vessel, it might not be regular white diesel. Some watercraft indeed use diesel and other, larger vessels
marine gas oil
(which is considered a low sulfur fuel oil or LSFO) as their source of bunker fuel.
What is the formula for fuel consumption?
The following formula is used to calculate fuel consumption in litres / 100kms, the most commonly used measure of fuel consumption.
(Litres used X 100) ÷ km travelled = Litres per 100km.
How do I calculate my daily fuel consumption?
-
Fill your tank to the top.
-
Zero the trip counter.
-
When you next fill up, note the mileage driven.
-
Fill the tank again and note the number of litres put in.
-
Divide the number of miles driven by the amount of fuel used in litres (miles per litre)
What is fuel density?
Fuel Density Defined
Density of fuel is
“the mass of fuel per unit volume”
. In some cases the density is expressed as a specific gravity or relative density, in which case it is expressed in multiples of the density of some other standard material, usually water or air.
What is the formula for diametral pitch?
|
Calculate When Defined Formula
|
Pitch Diameter (D) Number of teeth (N), the Normal Diametral Pitch and the Helix Angle (A)
D = N / (Pn X cos A)
|
Outside Diameter (OD) Pitch Diameter (D) and the Addendum (a) OD = D + (2 X a)
|
Outside Diameter (OD) Normal Diametral Pitch (P) and the Pitch Diameter (D) OD = D + 2/Pn

How much fuel does a supertanker use?
A Panamax container ship can consume
63,000 gallons of marine fuel per day
at that speed. Fuel use drops sharply as speeds decrease. A container ship can decrease fuel use close to one-third if it drops its speed 10%.
What is true slip?
Real slip or true slip
This is
the difference between the theoretical speed and the speed of advance
, express as a ratio or percentage of the theoretical speed. The real slip is always positive and it dependant of current.
