UNCONTROLLED IF PRINTED PRJ-PJL-PRC-008 Procedure

1 GENERAL

1.1 PURPOSE

This equipment Tag numbering procedure details the structure of tag numbering that needs to be followed to maintain consistency in QatarEnergy LNG operated facilities.

It will minimize conflicts and ambiguity, thus ensuring a reliable plant operations and maintenance.

This procedure shall be implemented in conjunction with QatarEnergy LNG procedure PRJ-PJL-PRC-005 - Facilities System and Unit Number Codes and Descriptions, and PRJ- PJL-PRC-080 - AIMS TAG Management Procedure.

1.2 SCOPE

This procedure is applicable to all QatarEnergy LNG facilities, including new greenfield projects built within all QatarEnergy LNG.

The soft calculations and logics in DCS, PLCs derived from field equipment tags which do not fall under the applications mentioned in section 2.1 need not follow this tag numbering philosophy. Examples: DCS, PLC internal calculation blocks, internal memory tags etc.

For the ICS Security Equipment, all the Greenfield projects shall follow the new Tagging convention described in Section 3.

All the tags (brownfield and greenfield projects) shall be reserved/verified as per AIMS Tag Management Procedure PRJ-PJL-PRC-080, prior to utilization in any drawings or P&IDs.

FEED tags under greenfield scope are considered temporary. Re-tagging of these FEED tags to be carried out during the EPC phase in accordance with the latest approved procedure. FEED tags under brownfield scope can be reserved in Tag Management System to avoid same tags used in other projects and the reserved FEED tags will be verified (Activated) during the EPC phase in accordance with applicable numbering procedure. If Long lead Item (LLI) cannot be retagged during EPC, those tags should be reserved and verified in Tag Management System before issue of purchase orders.

All existing facilities shall continue to use project specification tag structure for the future modifications (Brownfield projects) to maintain the consistency of the drawings within the same asset. Refer to Section 4 for more details.

1.3 CRITICALITY

This Procedure has been determined to be a Medium Criticality document.

1.4 KEY RISKS AND CONTROLS

Key Risks

Key Controls

Reference

Section 2,3 and 4.

Following the guidelines in this document from the early stage of project will minimize the risk

Following the guidelines in this document from the early stage of project will minimize the risk

Section 2 and 3.

Lack of consistency in equipment numbers may lead to time delays in locating the equipment, related documents, maintenance history, etc. This may adversely affect the overall efficiency of operations, maintenance and engineering day to day activities.

If projects do not follow QatarEnergy LNG guidelines on equipment numbering from early stage of project, there might be tag conflicts and ambiguity at the advanced stage of the project. Conflicts and inconsistencies detected at advanced stage of project may results in huge cost and time delay.

Table 1: Key Risks and Controls

1.5 CLASSIFICATION

This Procedure has been classified as Internal based on INF-ISG-POL-001 Information Classification Policy.

1.6 COMPLIANCE

All projects shall comply with the requirements as defined in this procedure to maintain consistency of equipment tagging in QatarEnergy LNG.

Compliance with this procedure is verifiable by Engineering Systems and Governance section at any time during project execution.

In case of any ambiguity regarding the use of this procedure, ESG team to be consulted for clarification on, and not limited to, the content, tag syntaxes, and requirement for new function codes.

2 DESCRIPTION OF DOCUMENT CONTENT

Explains the structure of tag number to be followed to maintain consistency in QatarEnergy LNG operated facilities.

2.1 DEFINITION OF TAG NUMBER

Tag number is a unique identification reference of an entity (equipment, instrument or function) within the QatarEnergy LNG operated facilities.

Unique tag number is required in following (but not limited to) purposes,  Required for unique reference in Piping and Instrumentation Diagrams (P&ID).  Required for unique reference in SAP for maintenance management and in permit

to work system.

 Required as unique

Identification of Equipment’s (Mechanical, Electrical, Instruments, Fire & Gas, and Telecommunication) and monitoring & control functions.

This Equipment Numbering Philosophy shall be applicable to all physical equipments and the functions (logics) which need to be referred by unique identification numbers for the purposes mentioned above.





Examples of physical items: Pumps, Compressors, Transformers, Valves, Panels etc. Examples of functions (soft tags): Shutdown functions-UZ, DCS logics- UY, etc.

Project need to ensure same tag numbers are used in field, F&G System and in all documentation. Mismatch of tags usage between field/ system/documentation leads to confusion, hence such mismatches are not acceptable.

Note:  No trailing spaces are allowed within the tag number structure. 

Engineering and Governance team should be consulted if there is any ambiguity.

2.2 REFERENCES

Equipment numbering and tagging philosophies used in existing assets in QatarEnergy LNG are listed in Appendix-7.
