1 Scope
This document specifies procedures and requirements for the transfer of bunkers to vessels by bunker
tankers using the Coriolis mass flow meter (MFM) system. It encompasses the process leading to the

It covers terminology, specifications, requirements and procedures on metrology, system integrity,
metering system selection and installation, acceptance test, bunker delivery and dispute handling.
NOTE Local and international regulations, such as the International Convention for the Prevention of
Pollution from Ships (MARPOL) can apply.

3.14
calibration
operation that, under specified conditions, in a first step, establishes a relation between the quantity
