TR 48 : Bunker mass flow metering
Note: SS 524 and SS 600 were revised in 2014.
From 1 Jan 2017, the Singapore national maritime
agency, MPA requires its bunker suppliers to use
approved MFM system for fuel oil bunkering.

• Quality ie marine fuel specifications• Quantity ie get what you pay for
Ø Measurement Ø Security of measured quantity
• Quantity issues, a constant challengeØ Biggest cost item for ships
Challenges in Bunkering
6
Stakeholders involved in TR 48
International / local ship owners, operators & charterers (bunker
buyers)
International / local bunker suppliers &
major oil companies
Bunker tanker owners and operators
International / local bunker surveyors &
calibration lab
Mass flow meter manufacturers
Individual bunkering experts
National maritime agency, Legal metrology authority & National metrology institute
International & national shipping &
bunkering associations
• National & International participation
• Building trust, confidence and acceptance

Key milestones • Singapore’s MFM bunkering project led by TC for Bunkering from
2009 • Achieved first milestone with 1st bunker tanker, MT Emissary using
MFM system, approved by MPA in line with requirements developed by the TC for Bunkering, to carry out the 1st commercial bunker delivery on 11 July 2012.
• Transport Minister announced in Apr 2014 the mandatory adoption of MFM system in Singapore by 1 Jan 2017
• Launch of TR 48 by SPRING Singapore on 16 Feb 2016 • 113 bunker tankers met MFM system requirements and approved
for fuel oil MFM operations by MPA as at 1 Jan 2017 • Mandatory use of MFM system for fuel oil delivery in Singapore
from 1 Jan 2017
New Application of MFM to Bunkering
8
• Coriolis meters good in single phase fluid flow, less so for 2-phase fluid flow when air is mixed with oilØ Operational control of aeration – a small % of total
delivered quantity. Ø Product conditionØ Maximize the quantity measured in single phase flow and
minimize line packing and tank stripping Ø Failure in bunkering application due to common “plug in
& play” mentality, whether on bunker tanker or receiving ship.
Ø Calibration alone not enoughØ Operational control ie metering procedure vital for
performance (0.5% expanded measurement uncertainty)Ø Measurement security
Key Success Factors
9
• The Coriolis meter needs to be set up as part of a custody transfer measuring system on board a bunker tanker to undertake the bunkering task
• A MFM system needs:
– To be properly sized and installed to meet rigorous requirements of TR48 for custody transfer on a bunker supply tanker
– To have a delivery procedure in place to
achieve the required performance of TR48
Bunker MFM System
10
Covers requirements of metering system qualification, installation, testing and procedures and documentation for bunker custody transfer using the Coriolis mass flow metering system.

Two Foundations underpinning TR 48
• Measurement Accuracy (Clause 6)
• System integrity (Clause 7)
TR 48 : 2015
12
• Measurement Accuracy (Clause 6)Ø Traceability to SI unit mass & calibrationØ Expanded measurement uncertainty of 0.5% of MFM
system• System integrity (Clause 7)
Ø Security of the measured quantity being fully delivered to the buyer’s ship
• Clauses 6 & 7 requirements need to be followed or complied with from meter selection stage to bunkering operations i.e. Clauses 8, 9 & 10
Two Key foundations
13
Clause 8 : Meter selection and installation requirements
• This Clause assists MFM system owner to meet requirements of Clauses 6 & 7
• Includes pre-selection screening, site survey and highlights the responsibility of tanker owners/operators and meter vendors in this process
• Correct selection and installation should result in the MFM system meeting the operational objectives of the user and leading to the approval of the MFM system and commercial service
TR 48 : 2015
14
Clause 9 : Acceptance test requirements
• MFM system is required to undergo an official acceptance test to validate that Clauses 6 & 7 requirements are met
• Success in the acceptance test will lead to MPA’s approval of the MFM system for bunkering service
TR 48 : 2015
15
Clause 10 : Metering procedures
• Optimise performance of MFM system
• Covers pre-delivery, delivery, post-delivery checks and documentation requirements for the delivery of bunker using a MFM system
• Monitor measurement integrity and system integrity during
bunkering, i.e. Clause 6 & 7 are complied with during bunkering
• Management of inventory through the meter totalizer log
TR 48 : 2015
17
• Weights & Measures Office, a division of SPRING Singapore, prescribes requirements on the meter for trade use
• MPA is the authority that implements and enforce compliance with TR 48 for each MFM system installed on the bunker tanker
Implementation & Enforcement
18
• More volume• Increased bunkering capacity• Less disputes• Higher productivity• More connectivity• Better business processes• Beyond bunkering
Benefits to industry
19
• Misunderstanding measurement uncertainty• Bunker supply chain issues, loading at oil
terminals to final delivery to ships • Small parcels and operational control on flow• Low viscosity fuel • System integrity breaches• When does a dispute arise?• Further developments
Post-implementation
