BUNKER CALCULATION
TAKE THE ULLAGE OF THE
TANK AS IT IS HEAVY OIL THE ULLAGE IS 2.99.mtr.ASK BRIDGE ABOUT TRIM SUPPOSE
TRIM IS 0.8mtr.BY AFT,FROM SOUNDING TABLE TAKE THE TRIM CORRECTION . IF ULLAGE
TRIM CORRECTION FOR 0.8mtr. is -2cm. NOW THE ULLAGE IS 2,97.mtr. THE VOLUME OF
ULLAGE IS 105.529.m3 ,THIS IS OBSERVED VOLUME,
TAKE THE TEMPERATURE OF THE TANK THE TEMPERATURE IS 48°C.
AS THE BUNKER DELIVERY NOTE THE DENSITY OF THE BUNKER IS 988.KG/m3.AT 15°C.
FROM THE VOLUME CORRECTION TABLE WE CAN FIND OUT THE CORRECTION FACTOR FOR THE OIL FOR 988.KG/m3 DENSITY IS 0.9773.
TAKE THE TEMPERATURE OF THE TANK THE TEMPERATURE IS 48°C.
AS THE BUNKER DELIVERY NOTE THE DENSITY OF THE BUNKER IS 988.KG/m3.AT 15°C.
FROM THE VOLUME CORRECTION TABLE WE CAN FIND OUT THE CORRECTION FACTOR FOR THE OIL FOR 988.KG/m3 DENSITY IS 0.9773.

THERE FORE
THE VOLUME OF OIL AT 15°C.WILL BE105.529 MULTIPLIED BY 0.9773 = 103.133.m3
THE DENSITY IS THE ABSOLUTE RELATION
SHIP BETWEEN MASS AND VOLUME, NOT WEIGHT TO VOLUME.THE DENSITY IS THERE FORE
"IN VACUO"
SO,
MASS = DENSITY X VOLUME = 988.kg X 103.133
= 101895.89.kg = 101.896.M.T.
THIS IS IN VACUO

FACTOR FOR CONVERTING WEIGHT IN VACUO TO WEIGHT IN AIR
|
975.7
to 1060.4
|
0.99895
|
SO WEIGHT OF THE BUNKER IN AIR = 101.896 X 0.99895 = 101.781.M.T.
