3 Consistent reel length was what the machine tenders needed to deliver. How? Length is proportonal to reel diameter Reel diameter was measured with a yardstck for 95 years BUT, there was variaton due to small changes in paper thickness We converted to what matered: Measurement of actual lineal footage Insensitve to variaton in thickness Reduced annual scrap by $400,000 It took a lot of change management to get it done

4 The mass of 500 sheets of paper of a certain size, based on the type of paper (writng, newsprint,.) Measured real tme, contnuously, with a sensor that travels back and forth across the machine How is the sensor calibrated?

5 A reel typically took about one hour to fll 60,000 feet long, 200 inches wide A sample of 5 sheets, 5x5 inches square, was very accurately weighed Sample size: % of the reel We could never accurately adjust the machine sensors We converted to what matered: Accurate rewinds of actual customer reels existed, ted back to the mother reel Customer paid by mass, so we had calibrated, certfed scales Samples >90% of the total reel were then used to tune machine sensors Signifcant $$$ savings in feedstock to the machines It required signifcant change management

6 What makes a good measurement Relevant to the atribute of interest Direct vs. inferred Repeatable Stable Utlizes a sample size as large as possible Immune to environmental efects and disturbances In the case of custody transfer measurements, linkage to a recognized, traceable standard Change isn t easy

7 Make sure I m getng what I m paying for Quantty and Quality Eliminate idle/downtme due to refueling operaton Reduce the number of billing discrepancies and arbitraton claims Fuel Storage Terminal Barge Repeatable, accurate measurement globally accepted Reasonable capital costs to support operatons Lifecycle cost considered for operatonal efciency Operating Vessel

8 During Validaton Actual Operatonal Challenges Volume to mass conversions Temperature compensatons Stacked uncertaintes of reference system Product quality concerns Fuel Storage Terminal Barge Inherent diferences between tank measurements Entrained gas (air bubbles) Product holdup in barge pipelines Placement of meter for buyer s confdence One Job, One Load inefciencies Operating Vessel

9 Measurements from barge to vessel use rulers/soundings to infer the volume transfer of bunker fuel, and an assumed density, to determine tonnage Density (and other quality dimensions) is validated via a tme-lagged sampling methodology Sample size is ~ % of the load* Coriolis meters directly measure what is of interest: real time mass flow and real time density * 1 liter sample of a 1500MT load

10 Direct mass fow measurement No moving parts, no maintenance No fow conditoning or straight run piping required It is common for other technologies to require up and downstream straight pipe runs, up to pipe diameters Inherently mult-variable measurement Flow, Density, Temperature Custody Transfer systems approval

11 Micro Moton embarked on a bunker fuel test program with Exxon, Victrol, Maersk and NMI in Roterdam and Antwerp Phase 1: Load Exxon refnery via Micro Moton meter installed on Victrol Barge; verify barge tanks with custody transfer certfed meter Phase 2: Dispense bunker fuel from Victrol Barge to Maersk Laust via Micro Moton meter Phase 3: Use Micro Moton meter installed on Maersk Laust to measure incoming bunker fuel Conducted testng under both ideal and non-ideal operatng conditons

17 Consider a Bunker with 5% entrained gas: A volume fow measurement will give a batch error of +5% Efect on mass measurement is negligible Drive Gain can be used to indicate presence of entrained gas

19 Direct mass fow measurement No moving parts, no maintenance No fow conditoning or straight run piping required It is common for other technologies to require up and downstream straight pipe runs, up to pipe diameters Inherently mult-variable measurement Flow, Density, Temperature Custody Transfer systems approval

20 A time or flow proportional sampler would not recognize this supply change

21 On board temperature sensor monitors real time temperature measurement Today, placement of the temperature probe is critical for optimum volume to mass conversion

22 Direct mass fow measurement No moving parts, no maintenance No fow conditoning or straight run piping required It is common for other technologies to require up and downstream straight pipe runs, up to pipe diameters Inherently mult-variable measurement Flow, Density, Temperature Custody Transfer systems approval
