Crude petroleum and petroleum products - Transfer accountability - Assessment of vessel experience factor on loading (VEFL) and vessel experience factor on discharging (VEFD) on ocean-going tanker vessels
This International Standard specifies two methods for establishing the average ratio between the quantity of oil measured on board an ocean-going tanker vessel and the corresponding quantity measured at a terminal. Method 1 is commonly used in the field. Method 2 is more statistically rigorous and is the referee method to be used in cases of dispute. Either method can be used on loading the vessel [vessel experience factor on loading (VEFL)] or on discharging the vessel [vessel experience factor on discharging (VEFD)].
This International Standard applies to shore terminals that determine volumes received or delivered using static tank measurements or dynamic meter measurements carried out according to good accepted industry practice. It also applies to floating storage or off-shore facilities that load ocean-going vessels using dynamic meter measurements carried out according to good accepted industry practice.
This International Standard is not applicable to the assessment of the vessel experience factors of barges.
