1 INTRODUCTION

HMC-2A, the Refinery Measurement Database Committee of the Energy Institute (EI) was established in 1985 as the PML-5 Refinery Loss Control Committee and began data collection and analysis to an agreed format in 1989. The committee is made up of refinery operators from the main HMC-2 Refinery and Downstream Measurement Committee.

The main committee develops and maintains metering and proving standards and addresses issues relating to static and dynamic measurement, facilities balances, product quality control/management, emissions and the environment. A key publication is EI HM 32 Guide to product hydrocarbon management at marketing terminals. This document provides advice on operations and procedures for the control of both apparent loss (i.e. that caused by measurement errors and incorrect or inadequate accounting procedures) and physical loss at petroleum storage installations, including airports, where product is received, stored and despatched by pipeline, sea, road or rail systems.

The general aim of the database committee is to improve refinery loss control through better understanding and through production of benchmark loss figures. The committee encourages adoption of improved and harmonised measurement standards and procedures and maintains EI HM 31 Guide to product hydrocarbon management in petroleum refinery operations, which is accepted by most major oil companies as the industry standard for refinery oil accounting and loss control.

The committee acts as a forum to share best practices and review new equipment relevant to loss control. Members are also kept informed of new developments in relevant international standards.

Each committee Member submits measurement data annually (and generally in accordance with HM 31) on a confidential basis. This data is analysed to provide a confidential report to individual Members which shows their losses in various categories compared with those for other refineries in the database. Individual Members are not able to identify refineries in the report other than their own. The analysis is confidential to Members but, with Members’ approval, data is extracted from this report for publication.

With its focus on accounting, measurement and loss, the HMC-2A report compliments other industry data gathering and comparison initiatives which consider performance and efficiency, usually through comparison of volumetric gain. The separation of accounted and unaccounted losses offers further insight into measurement and loss control operations and can indicate opportunities for improvement.

Historically, assembly of some of the mass based emissions data required additional effort at the refineries but this data is now collected for environmental monitoring reports for government authorities and is readily available.

The Committee operates in accordance with competition law and under written Terms of Reference (Annex A). The database is maintained and reports are prepared by an independent Consultant.

Access to pooled data and information derived from a number of refineries adds to the knowledge and can improve the operation of individual loss control groups, providing benchmarks for key losses (measurement differences).

This document describes how the committee operates and is produced as a guide to existing and potential new Members. In addition to the operation of the committee, data submission requirements and report contents are discussed in detail together with the confidentiality arrangements under which the data is handled.

2 COMMITTEE MEMBERSHIP

Membership of the committee is open to all companies who have refinery loss data to contribute. However, membership applications are considered by the committee, who vote to approve new Members.

Each Member company nominates one representative who will receive the reports and meeting minutes and who will have voting rights at committee meetings. However the meeting forum is flexible and Members are welcome to send additional representative(s) to participate in discussions, etc.

Where Member companies have a number of refineries, representatives are expected to use best efforts to collect data from their associates. Where Member companies have more than one refinery submitting data they will receive a report for each refinery and representatives from each refinery will be entitled to attend meetings. However, the Member company will have only a single vote in committee ballots.

A Chair is elected every three years from amongst the Members.The Consultant who carries out the analysis and maintains the database also attends

meetings. However, the Consultant is not a Member and does not have voting rights.


6

3 THE INDEPENDENT CONSULTANT

The Consultant is appointed by the committee, working through the Chair. There is no 'term of office' as the Consultant is engaged annually on a commercial basis. It is in the interests of the panel to maintain continuity and there have been only two consultants used since the committee was established.

All data resides with the Consultant and is not retained at the EI.


7

4 CONFIDENTIALITY

Committee Members and the Consultant work under strict confidentiality agreements such that no information relating to individual companies can be passed to other companies, whether or not they are Members, and no anonymous information derived from the database is passed outside Member companies other than in the form of articles for publication which are approved by the panel.


8

5 FEES

Fees are payable annually by each Member company directly to the Consultant. Invoices are normally issued as the annual reports are distributed.

Fees are calculated each year in advance on the basis of day rates and expenses for attendance at meetings. These are negotiated and agreed with the committee and are fixed in advance of each years’ work.

Each Member is charged the same basic fee for each refinery. As an indication of costs the basic fee for 2013 was GBP £1 045 (approx USD $1 600).

Individual Members are free to request additional reports or studies from the Consultant for which they will negotiate their own additional fees.


9

6 MEETINGS

The main meeting is usually held in June when a presentation of the analysis of previous years’ data is made. Annual reports covering the previous years’ data are issued in advance of this meeting.

If required, a second meeting is held in November to discuss any interim work, changes to the data required or the format of the next years’ report.

The meetings provide an excellent forum for discussion of loss control topics, bringing together specialists from a number of the major oil companies.

Meetings are normally run immediately before or after meetings of the main HMC-2 Refinery and Distribution Measurement Committee as most Members sit on both committees.

Meetings are hosted by the EI in London. However, it is the intention of the committee to hold meetings in the various Member countries whenever possible.

It is not mandatory for Members to attend meetings.

7 REFINERY DATA

7.1 INTRODUCTION

The objective of the committee is to obtain as much data as possible for analysis as this will add to the value of the resulting reports. While it is preferable for data to be submitted in accordance with the data submission sheet (Annex B), the input system can be flexible. The intention being that in most cases Members will be able to submit data direct from existing in-house files without the need for significant manipulation.

The quality of the information produced depends heavily on the consistency of the data going in. Members are therefore asked to ensure that data submitted complies strictly with the descriptions in Annex B and definitions in HM 31.

The Consultant should be contacted directly if any questions arise.

7.2 DATA SUBMISSION

The data is stored and analysed on an annual basis. Data for each year up to December 31 must reach the Consultant by February 1 of the following year. The submission date must be met otherwise data may be excluded from the database. The Consultant should be contacted directly if there are any problems with data submission.

Membership is conditional on submission of data. Members who do not submit data for a given year will not receive a report and will not be admitted to meetings in the year concerned. No fee will be charged. Membership can be resumed provided data is submitted in the following year.

Data may be submitted by e-mail on an attached file.

7.3 DATA FORMAT

Data should preferably be submitted in spreadsheet form (Excel, or equivalent).

7.4 UNITS

The database is run on a mass basis; tonnes.

7.5 INCOMPLETE DATA

If all the requested data is not available, or perhaps not collected for a particular refinery, it may be possible to use estimated figures based on industry averages for missing values. Assistance can be provided in such cases.

8 COMMITTEE ISSUES AND REPORTS

8.1 TECHNICAL ISSUES

Potential sources of mass balance error based on Members’ experience include but are not limited to the following, which have all been addressed and are discussed regularly:

− The impact of density errors on month-end stock accounting and the timing of the testing and update of densities in inventory systems.

− Problems associated with obtaining representative density data from layered tank contents.

− The effect of water and sediment content variations on crude oil density data. − Free water tank dip measurement errors due to emulsion in slop tanks. − The handling of shipments in progress over month-end. − Inventory issues due to tanks being shown in incorrect product service, inventory

in tanks not being reported and inventory being reported in tanks that are out of service.

− Deliveries or receipts being over or understated. − Internal fuel consumption being over or understated. − Problems with accounting satisfactorily for coke inventory.

Other technical areas that have been or are being looked at by the Committee are: − Issues relating to slop volatile organic compounds (VOCs), and accounting for

received ship’s ballast. − Procedures for monitoring for custody transfer meter drift and re-proving frequencies. − The relationship of refinery loss to Solomon Complexity. − The use of changes in flare gas analysis data to identify the likely source of increased

flaring. − New developments in closed and restricted sampling equipment. − Experience with pipeline leak detection systems. − Experience with data reconciliation systems.

8.2 TYPICAL REPORT CONTENT

Report content has developed over the years and is modified from time to time in order to include investigation of issues which become of particular interest to Members. However, reports will generally include analysis as shown in the following example for six refineries, nominally for 2011. The refinery receiving the report is Refinery X.

Overall losses

The 2011 database comprises data from six member refineries.The average refinery loss represents 0,44 % of processed inputs (Figure 1). There

is a wide variation between refineries (0,32 % to 0,67 %). Average loss was equivalent to 0,44 % of processed inputs. Refinery X matched the average in 2011.

When compared with the overall average for the other member refineries, excluding the data from Refinery X, Figure 5 shows that the overall loss for the other refineries has been higher than the data for Refinery X since 2006. However, it would appear that the improving trend from 2007 to 2009 has not been maintained, with the difference decreasing significantly in 2010 and again in 2011.

Figure 5: Three year average loss data

Accounted losses

The data show that Refinery X was able to account for a total of 46,2 % of its recorded loss for 2011 whereas the overall average for all six refineries was 46,8 %. This compares with an accounted loss of 47,0 % of the recorded loss for the average excluding Refinery X.

Generally, flaring represents the major accounted loss in almost every refinery, usually followed by either process fugitives or drainage VOCs as the next largest source. Refinery X matches this pattern. The comparison against the average of all the refineries is shown in Figure 6 while the comparison against the average of the other five refineries is shown in Figure 7.

Flaring loss

Figure 8 shows the flaring performances of the different refineries (expressed as a percentage of the processed input quantities). Large differences are apparent between the best and worst cases. The overall average refinery flared 0,13 % of processed inputs, so there would appear to be further scope to reduce flaring at several refineries (particularly Refineries X and V). At 0,16 %, Refinery X is only a little higher than the overall average.

Figure 8: 2011 Refinery loss control survey – flare data

Figure 9 shows the historical flare losses as a percentage of processed inputs for Refinery X and the overall average of all the refineries. There have been some significant variations in flaring at some member refineries, with the result that the average flare percentage apparently increased significantly from 2006 to 2007, but has then decreased again in recent years. In contrast, flaring at Refinery X had been fairly consistent at around 0,35 % of processed inputs (± 0,03 %) but was significantly reduced during 2009 (to 0,26 %). Whilst this reduction was not maintained in 2010, the reported flare losses have decreased further in 2011, and at 0,16 % Refinery X is now finally close to the overall average (that has also been reducing since 2007).

When the data are compared with the average of the member refineries but excluding Refinery X (Figure 10), the same conclusion is apparent. From 2005 to 2008, flaring at Refinery X was consistently higher than at the other current member refineries, but that improved performance was achieved in both 2009 and 2011, so that the flare loss has been very substantially decreased and the flare performance of Refinery X is now comparable with the average of the other member refineries.

Figure 10: Historical flare loss comparisons

Loss of VOCs

Figure 11 shows some large differences in the VOC losses reported by the different refineries (expressed as a percentage of the processed input quantities) with almost a four-fold difference between the best and worst cases.

The overall average refinery VOC loss was 0,027 % of processed inputs, while Refinery X reported VOC losses of 0,038 %. Whilst this was not the highest VOC loss reported, several other Members were apparently able to control their VOC losses better than this; so there would appear to be scope for Refinery X to reduce VOC losses.

ANNEX ACOMMITTEE TERMS OF REFERENCE

The Refinery Measurement Database Committee HMC-2A terms of referenceThe Committee is constituted under the auspices of the EI and reports to the

Hydrocarbon Management Committee (HMC).

Objectives

The Committee’s objectives are:1. To develop and maintain a database of refinery measurement data for statistical analysis.2. To improve industry’s understanding of the extent and causes of refinery losses, both real

and apparent.3. To encourage the adoption of improved measurement standards and procedures through

dissemination and publication of results.4. Through its sister committee, HMC-2, to identify work items (document development or

practical projects) aimed at improving refinery hydrocarbon management.

Membership

The Committee is open to all oil companies who are willing to submit data for analysis and who agree to abide by the confidentiality agreement. Oil refinery personnel are required to submit the loss accounting data for their refinery (ies) annually, using the agreed EI HMC-2A format to permit meaningful comparative analysis.

Members’ representatives should preferably be refinery based with day-to-day responsibility for hydrocarbon loss control.

To broaden the scope of discussion and to add value to the work of the committee, invitees may be asked to attend and participate at meetings.

Data submission and confidentiality

Data from each Member will be submitted on a confidential basis to an independent Consultant (the consultant) for analysis.

Consultants agreement

The following statement shall be signed by the Consultant and held by the Chief Executive of the EI:

I hereby affirm that I shall maintain the CONFIDENTIALITY of all individual company data submitted for analysis.

I shall not pass information submitted by individual Member companies to other companies except in the form of cumulative reports which will be composed in a manner approved by the Membership and submitted to Member companies only.

I shall not pass on any information which is not in the public domain and which has come to my attention in my capacity as Consultant without the prior consent of the Committee. In no case will I release specific information about a company without written permission of that company’s HMC-2A Committee representative.

I shall not include in any report or otherwise disclose any individual company data which I could reasonably expect would enable the submitting company to be identified.

Work and publication of results

Publication of general information and extracts from reports will be encouraged, but will require the unanimous agreement of the Committee Members.

Meetings

The Committee will normally meet in the spring of each year to review the analysis of the previous year’s data. A second meeting may be held in the autumn. Meetings will be linked appropriately with meetings of HMC-2; the Refinery and Distribution Measurement Committee.

Meetings will be attended by Members’ representatives (one per refinery) who may be accompanied by a colleague. Attendance of additional observers will be at the discretion of the Chair.

The EI may participate at Committee meetings as observers, normally through the attendance of the Technical Manager, Standards who will receive meeting minutes and general reports on progress. Any EI representatives attending meetings will be subject to the same confidentiality requirements as the Members.

Representatives of prospective new Members may be invited to attend one meeting as guests at the discretion of the Chair, but shall not attend sessions where the confidential loss performance data from other refineries is presented or discussed without the prior consent of the refinery Members concerned.

Committee officers

Chair and Vice Chair

The Chair and Vice Chair will be selected every three years by the Committee (majority vote), before the Autumn meeting in accordance with the procedure detailed in Appendix 1. The new officers will take up their positions immediately following the Autumn meeting.


22

Consultant

The independent Consultant will be selected by Committee Members. Fees will be agreed by the Committee annually and divided equally between Members. Each Member will be responsible for settling the Consultant’s invoice for their portion of the fee.

Secretary

The duties of Secretary will be undertaken by a representative from EI staff.

Voting

Each Member shall have one vote on matters considered by the Committee. The vote will be exercised by the Member’s nominated representative.

Amendments to these Terms of Reference will require the approval of at least two thirds of the Committee Members.

The quorum for meetings will be a minimum of 50 % of Committee Members. Consensus will be sought for decisions but where a vote is called the outcome will be based on a simple majority of those in attendance.

Changes to the Terms of Reference, election of committee officers and all documents for publication will be subject to email ballot to allow all Members to participate.

Appendix 1

Selection Procedure for Chair and/or Vice Chair1. All candidates for either of the two positions must submit their names to the Secretary

approximately six weeks before the Spring meeting. There will be no nomination or seconding process. Representatives from ALL Member companies are eligible to stand.
