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

5

Singapore’s Solution

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

7

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.

TR 48 : 2015 - Scope

Metrology and Security

MFM Installation

MFM System Approval for Operation

Bunkering Operations

Clause 6 : Traceability and calibration requirements Clause 7 : System integrity requirements Clause 8 : Meter selection and installation requirements Clause 9 : Acceptance test requirements Clause 10 : Metering procedures Annex AB : Dispute resolution

11

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

16

Trust & Confidence

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
