3.18.1
load on top
LOT
(procedure) shipboard procedure of collecting and settling water and oil mixtures, resulting from ballasting and tank operations (usually in a special slop tank or tanks) and the subsequent preparation for loading of cargo onto such mixtures
3.18.2
load on top
LOT
(practice) act of co-mingling an on-board quantity with cargo being loaded
3.19
meter factor
ratio of the actual volume of liquid passing through a meter to the volume indicated by the meter
3.20
net standard volume
NSV
volume of crude petroleum excluding total water and total sediment, calculated at standard conditions
NOTE 1 The standard conditions are in general 15 °C and 101,325 kPa.
NOTE 2 This may be either the volume in a tank or the difference between the volumes before and after a transfer.
3.21
net apparent mass-in-air of oil
value obtained by weighing the NSV of oil in air against standard masses without making correction for the effect of air buoyancy on either the standard masses or the object weighed
3.22
on-board quantity
OBO
sum of liquid volume and non-liquid volume in cargo tanks just before loading, excluding clingage, hydrocarbon vapours and the contents of associated pipelines and pumps
3.23
outturn quantity
quantity of crude petroleum discharged from a vessel as measured in the shore system
3.24
outturn certificate
document issued by the receiving party, certifying the outturn quantity
3.25
outturn loss/gain
difference in NSV between the quantity shown on the bill of lading and the quantity shown on the outturn certificate
NOTE It may be expressed as a volume or a percentage of the bill of lading quantity.
3.26
quantity remaining on board
ROB
sum of liquid volume and non-liquid volume in cargo tanks just after completion of discharge, excluding clingage, hydrocarbon vapours and the contents of associated lines and pumps
3.27
reference point
point on the gauge hatch or top of a tank from which the reference height of the tank is established SEE also datum point (3.4)
3.28
reference height
distance from the datum point (3.4) to the reference point (3.27)
3.29
slops
material contained in slop tanks or other designated tanks, resulting from tank washing, change of ballast, and oil- recovery procedures
3.30
suspended sediment
non-hydrocarbon solids present within the crude petroleum but not in solution
3.31
suspended water
water contained within the crude petroleum that is finely dispersed as small droplets
NOTE It may, over a period of time, either collect as free water or become dissolved water, depending on the conditions of temperature and pressure prevailing.
3.32
total calculated volume
TCV
gross standard volume plus the free water measured at the temperature and pressure prevailing
3.33
total observed volume
TOV
volume of crude petroleum, total water and total sediment, measured in a tank at the crude petroleum temperature and pressure prevailing
NOTE This may be either the volume in a tank or the difference between the volumes before and after a transfer.
3.34
ullage
outage
distance between the surface of a liquid in a tank and a fixed reference point on the top of the tank, or capacity of a tank not occupied by liquid
3.35
vessel experience factor
VEF
mean value of the vessel load ratios (VLRs) or vessel discharge ratios (VDRs) obtained after the required number of qualifying voyages
3.36
vessel load ratio
VLR
ratio of the TCV measured on board a vessel immediately after loading, less the OBQ, to the TCV measured by the loading terminal
3.37
vessel discharge ratio
VDR
ratio of the TCV measured on board a vessel immediately before discharge, less the ROB, to the TCV measured by the receiving terminal
3.38
vessel-shore difference
difference between the TCV recorded by the vessel corrected for OBQ or ROB as appropriate， and the TCVrecorded by the shore
3.39
volume correction factorVCF
factor for correcting oil volumes to a standard reference temperature
3.40
water cutdip
procedure of locating the oil/water interface for the purpose of determining the volume of free water in a shore tankor vessel compartment
3.41
wedge formula
mathematical means to assess small quantities of measurable liquid and/or non-liquid material which is in a wedgeconfiguration and does not touch all bulkheads of the vessel’s tank
NOTE 1 The formula is based on cargo compartments characteristics, vessel trim and the depth of the material.NOTE2 The wedge formula should be used only when the liquid does not cover the entire bottom of the vessel’s tank.
