Crude petroleum and petroleum products. Transfer accountability. Assessment of vessel experience factor on loading (VEFL) and vessel experience factor on discharging (VEFD) of ocean-going tanker vessels Ingestion-build-65808 EN 61558-2-7:19971 Scope 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)]
