INTRODUCTION
Objectives of the NORSOK Coding System
The coding system has been developed to meet the following main objectives:
• To support the objectives of NORSOK.• Compliance with the functional NORSOK standards to enable standardised deliveries
and transfer of experience.• To contribute to a quick project initiation and minimum project execution time.• To ensure common coding for multifunctional teams and multi-skilled personnel.• To enable and ensure efficient and standardised communication within the petroleum
and natural gas industries.• To support functional breakdown of a facility and related documentation of systems,
subsystems and equipment to ensure standardisation and reuse. Main Changes from revision 2 to revision 3 These are in summary: • The functional breakdown has been simplified in that the number of levels in breakdown have
been reduced; the unit and sub-unit have both been removed from the structure• In general the identification codes have been tried to be made simpler and less classifying;
change to simpler identification• The documentation identification code has been simplified• The TAG Code format has been designed to 6 different main types, there is no general coding
format covering all main groups• Association of attributes to the code formats have been made more explicit, more have been
made mandatory. The attributes are in general anticipated to be registered as informationelements in the information management systems / technical databases
• The definition of systems and subsystems have been revised and made more explicit• Tag coding of Telecommunication does not have a separate section, but has been included as part
of instrumentation• HVAC is regarded to be as a utility system in general, and a special system• Documentation codes have been simplified

1 FOREWORD
NORSOK (The competitive standing of the Norwegian offshore sector) is the industry initiative toadd value, reduce cost and lead time and remove unnecessary activities in offshore fielddevelopments and operations.
The NORSOK standards are developed by the Norwegian petroleum industry as a part of theNORSOK initiative and are jointly issued by OLF (The Norwegian Oil Industry Association) andTBL (Federation of Norwegian Engineering Industries). NORSOK standards are administered byNTS (Norwegian Technology Standards Institution).
The purpose of this industry standard is to replace the individual oil company specifications for usein future petroleum industry developments and operations, subject to the individual company'sreview and application.
The NORSOK standards make references to international standards. Where relevant, the contents ofthis standard will be used to provide input to the international standardisation process. Subject toimplementation into international standards, this NORSOK standard will be withdrawn.
All annexes except annex F, G and H are normative.
2 SCOPE
This coding system has been developed for tag coding and document coding.
Coding of articles and bulk materials is governed by the NORSOK standard Z-CR-002, Componentidentification.

5 DOCUMENT CODING
5.1 GeneralThis section of the Coding System covers the coding of documents used throughout the life of afacility, including technical (engineering and manufacturing), administrative and procurementdocuments.
A complete document code consists of the document identification code and mandatory attributes.
5.2 Document identification code formatThe document identification code structure is:
ZZZZ -ZZZZZ -A -NNNNProject/facility codeOriginator codeDiscipline codeSequence number
The project/facility code shall be a maximum of four alphanumeric characters.
The originator code is identified by maximum five alphanumeric characters. The originator codeshall not be changed, even if the responsibility for the document is changed. The Achilles codeshould be used as the originator code.
The discipline code is identified by one alphabetic character.
Sequence number shall start from 0001 for each originator, and per discipline. No intelligenceshall be included in the sequence number
The project/facility code, originator code, discipline code and sequence number shall be separatedby a hyphen ( “-” ) character. This character shall only be used as a separating character.
Examples: S5-10696-P-0001A Saga Petroleum project, Achilles code as originator code (Aker Engineering), and first process document.
C010-KE-I-0001A Phillips Petroleum project, project allocated originator code (Kværner Engineering),first instrument document.
Coding system Z-DP-002Rev. 3, October 1996
NORSOK standard Page 7 of 36
5.3 Mandatory attributesThe mandatory attributes shall be used to enable further detailed description, cross-referencing andpresentation.
All mandatory attributes shall be registered in the document information system and shown on thedocument. When not applicable NA shall be filled in.
The mandatory attributes are:• System (Annex A)• Subsystem (Annex A)• Document Type (Annex D)• Area (Annex E)• Title (See below)• Responsible Party (See below)• Revision (See below)• Revision Date (according to ISO 8601, 1988. Example: 19960827)• Purchase order identification
(Only applicable for supplierinformation)
See below
More then one attribute may be defined. If more than one is defined it shall be registered indocument information system.
The title shall describe the content of the document in a concise way, max. 80 characters.
The responsible party code identifies the organisational unit responsible for the document. Theresponsible party code is identified by up to five alphanumeric characters. The responsible partycode shall, at first, be the same as the originator code, but may change during a document's lifecycle. For example a document created by an engineering contractor may have its responsibilitytransferred to a fabricator and later to a hook-up/commissioning contractor. The responsible partycode shall be changed in the document information system each time a document is transferred fromone responsible party to another. If the document is revised the responsible party code will also bechanged on the document as well as in the document information system.
Revision codes. The purpose of the sequential revision number, format NN, is to give each revisiona unique identification. The two character sequential number starting at 01 shall be given for thedocuments first issue and shall be increased with one for each revision.
Purchase order identification may be individually defined.
