Introduction

This document was developed for the benefit of the bunker industry comprising ship owners, operators,

charterers, bunker suppliers, bunker craft operators and bunker surveyors and is intended to enhance

the efficiency of bunkering operations and promote best practices in the measurement of bunker fuel

delivered.

This document sets out the international best practices which documents principles, requirements and

procedures in the application of mass flow metering to bunkering.

This document does not alter the contractual obligations of the parties involved in the bunker delivery.

3.14
calibration

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

bunker(s)

any fuel (Class F - ISO 8217) supplied to a vessel for its propulsion and/or operation

3.7
bunker delivery note (BDN)

proprietary document of the bunker supplier providing details of the quality and quantity of the

bunker(s) delivered by the bunker tanker to the vessel
3.8
bunker metering ticket (BMT)
ticket printed at the end of bunkering operation
3.9
bunkering operation

bunker loading, bunker tanker to bunker tanker transfer operation or a bunker delivery operation

3.10
bunker supplier
company which contractually agrees with the buyer to deliver the product
3.11
bunker surveyor

person who inspects, measures, samples, investigates and reports as required on the bunkering

operations
3.12
bunker tanker
bunker tanker supplying bunker(s) to the vessel
3.13
bunker tanker operator
company which operates the bunker tanker
3.14
bunker tanker representative

an individual who represents the bunker supplier and is responsible for bunkering operations and

documentations
3.15
calibration

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

values with measurement uncertainties provided by measurement standards and corresponding

indications with associated measurement uncertainties and, in a second step, uses this information to

establish a relation for obtaining a measurement result from an indication
[SOURCE: JCGM 200]
3.16
calibration factor

numerical factor(s) unique to each sensor derived during sensor calibration, which when programmed

into the transmitter ensures that the meter performs to its stated specification
[SOURCE: ISO 10790]
3.17
calibration interval
time interval between two consecutive calibrations

3.18
chief engineer

chief engineer of the vessel who is responsible for receiving bunkers and documentation of the

bunkering operation
3.19
commissioning/re-commissioning

process whereby the critical precision parameters impacting custody transfer are verified/checked.

Any setting changes during commissioning/ recommissioning is traceable to factory settings and

justified adjustments to meet measurement uncertainty / type classification
3.20
conformity body

independent party or party accredited by national body that undertake conformity assessment

activities such as verification, testing, inspection and certification
3.21
conventional mass

conventional mass value of a body is equal to the mass of a standard that balances this body under

conventionally chosen conditions. The unit of the quantity “conventional mass” is the kilogram. Also

known as mass in air
The conventionally chosen conditions are:
3 3
t = 20 °C; ρ = 1.2 kg/m ; ρ = 8 000 kg/m

[OIML D028]
3.22
custody transfer point
point at which, the bunker is defined as being delivered or loaded
3.23
drip sampling container

clean and dry containers used for collecting drip samples during the entire bunkering operation

3.24
initial zero adjustment

setting the indication of mass flow rate to zero with the flowrate completely stopped and fully filled

flow meter according to approved procedure, before it is ready for custody transfer usage

3.25
linearity of mass flow meter

consistency of change in the scaled output of a Coriolis flow meter, for a related, scaled change in the

input of the flow meter
[SOURCE: ASME MFC-11]
3.26
low flow cut-off

transmitter setting which sets the meter output(s) to zero flow if the flow rate falls below a preset

value [ISO 10790]. This setting inhibits the registration of flow when the flow meter is not properly

filled with subject fluid that can lead to large measurement errors.
3.27
mass

physical quantity which can be ascribed to any material object and which gives a measure of its quantity

of matter [OIML D028] Also known as true mass

ISO/DIS 22192:2019(E)
3.28
mass flow meter (MFM)

device consisting of a flow sensor (primary device) and a transmitter (secondary device) which primarily

measures the mass flow by means of the interaction between a flowing fluid and the oscillation of a

tube or tubes; it may also provide measurements of the density and the process temperature of the fluid

[SOURCE: ISO 10790]
3.29
mass flow meter system (MFM system)

comprises the mass flow meter, its ancillary devices, pipelines and sealing points between the pump

suction and the custody transfer point
3.30
mass flow rate

flow rate at which the quantity of fluid which passes the MFM is expressed as mass and denoted in MT/h

[SOURCE: ISO 10790]
3.31
master
master of the bunker tanker or the vessel receiving bunker(s) as the case may be
3.32
maximum mass flow rate (Q )
max

maximum flow rate, up to which, the MFM system has been qualified to operate in compliance with the

required accuracy. The maximum value is normally determined by the application
3.33
measurand
quantity intended to be measured
[SOURCE: JCGM 200]
3.34
measurement uncertainty

non-negative parameter characterizing the dispersion of the quantity values being attributed to a

measurand, based on the information used
[SOURCE: JCGM 200]
3.35
measuring system

system comprising a mass flow meter, its ancillary devices and additional devices

3.36
meter reading
value obtained from the non-resettable totaliser(s).
3.37
meter stability

property of a measuring instrument, whereby, its metrological properties remain constant over time

Note 1 to entry: Stability may be quantified in several ways:

EXAMPLE 1 Example1: In terms of the duration of a time interval over which a metrological property changes

by a stated amount
EXAMPLE 2 In terms of the change of a property over a stated time
