Neither the whole nor any part of this document may be reproduced, stored in any retrieval system or transmitted in
3、 any form or by any means (electronic, mechanical, reprographic, recording or otherwise) without the prior written consent of the copyright owners. PREFACE DEP (Design and Engineering Practice) publications reflect the views, at the time of publication, of: Shell International Oil Products B.V. (SIO
4、P) and Shell International Exploration and Production B.V. (SIEP) and Shell International Chemicals B.V. (SIC) The Hague, The Netherlands, and other Service Companies. They are based on the experience acquired during their involvement with the design, construction, operation and maintenance of proce
5、ssing units and facilities, and they are supplemented with the experience of Group Operating companies. Where appropriate they are based on, or reference is made to, national and international standards and codes of practice. The objective is to set the recommended standard for good design and engin
6、eering practice applied by Group companies operating an oil refinery, gas handling installation, chemical plant, oil and gas production facility, or any other such facility, and thereby to achieve maximum technical and economic benefit from standardization. The information set forth in these publica
7、tions is provided to users for their consideration and decision to implement. This is of particular importance where DEPs may not cover every requirement or diversity of condition at each locality. The system of DEPs is expected to be sufficiently flexible to allow individual operating companies to
8、adapt the information set forth in DEPs to their own environment and requirements. When Contractors or Manufacturers/Suppliers use DEPs they shall be solely responsible for the quality of work and the attainment of the required design and engineering standards. In particular, for those requirements
9、not specifically covered, the Principal will expect them to follow those design and engineering practices which will achieve the same level of integrity as reflected in the DEPs. If in doubt, the Contractor or Manufacturer/Supplier shall, without detracting from his own responsibility, consult the P
10、rincipal or its technical advisor. The right to use DEPs is granted by SIOP, SIEP or SIC, in most cases under Service Agreements primarily with companies of the Royal Dutch/Shell Group and other companies receiving technical advice and services from SIOP, SIEP or SIC. Consequently, three categories
11、of users of DEPs can be distinguished: 1)Operating companies having a Service Agreement with SIOP, SIEP, SIC or other Service Company. The use of DEPs by these Operating companies is subject in all respects to the terms and conditions of the relevant Service Agreement. 2)Other parties who are author
12、ized to use DEPs subject to appropriate contractual arrangements. 3)Contractors/subcontractors and Manufacturers/Suppliers under a contract with users referred to under 1) or 2) which requires that tenders for projects, materials supplied or - generally - work performed on behalf of the said users c
13、omply with the relevant standards. Subject to any particular terms and conditions as may be set forth in specific agreements with users, SIOP, SIEP and SIC disclaim any liability of whatsoever nature for any damage (including injury or death) suffered by any company or person whomsoever as a result
14、of or in connection with the use, application or implementation of any DEP, combination of DEPs or any part thereof. The benefit of this disclaimer shall inure in all respects to SIOP, SIEP, SIC and/or any company affiliated to these companies that may issue DEPs or require the use of DEPs. Without
15、prejudice to any specific terms in respect of confidentiality under relevant contractual arrangements, DEPs shall not, without the prior written consent of SIOP and SIEP, be disclosed by users to any company or person whomsoever and the DEPs shall be used exclusively for the purpose for which they h
16、ave been provided to the user. They shall be returned after use, including any copies which shall only be made by users with the express prior written consent of SIOP and SIEP. The copyright of DEPs vests in SIOP and SIEP. Users shall arrange for DEPs to be held in safe custody and SIOP or SIEP may
17、at any time require information satisfactory to them in order to ascertain how users implement this requirement. All administrative queries should be directed to the DEP Administrator in SIOP. NOTE: In addition to DEP publications there are Standard Specifications and Draft DEPs for Development (DDD
18、s). DDDs generally introduce new procedures or techniques that will probably need updating as further experience develops during their use. The above requirements for distribution and use of DEPs are also applicable to Standard Specifications and DDDs. Standard Specifications and DDDs will gradually
19、 be replaced by DEPs. DEP 31.38.01.13-Gen.

December 1998 Page 3 1.INTRODUCTION 1.1SCOPE This DEP specifies requi
22、rements and gives recommendations for the compilation of a bill of material (BOM) on the basis of piping isometrics, and gives detailed instructions for the preparation and completion of the various documents forming part of such a BOM. This is a revision of the DEP of the same number dated April 19
23、92; a summary of the main changes is given in (1.5). 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIOP and SIEP, the distribution of this DEP is confined to companies forming part of the Royal Dutch/Shell Group or managed by a Group company, and to Contr
24、actors nominated by them (i.e. the distribution code is “C“ as defined in DEP 00.00.05.05-Gen.). This DEP is intended for use in oil refineries, chemical plants, gas plants and exploration and production installations. If national and/or local regulations exist in which some of the requirements may
25、be more stringent than in this DEP, the Contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable as regards safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the
26、Principal of any deviation from the requirements of this DEP which is considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate with the Authorities concerned with the object of obtaining agreement to follow this DEP as closely as possible
27、. 1.3DEFINITIONS 1.3.1General definitions The Contractor is the party which carries out all or part of the design, engineering, procurement, construction, commissioning or management of a project or operation of a facility. The Principal may undertake all or part of the duties of the Contractor. The
28、 Manufacturer/Supplier is the party which manufactures or supplies equipment and services to perform the duties specified by the Contractor. The Principal is the party which initiates the project and ultimately pays for its design and construction. The Principal will generally specify the technical
29、requirements. The Principal may also include an agent or consultant authorised to act for, and on behalf of, the Principal. The word shall indicates a requirement. The word should indicates a recommendation. 1.4CROSS-REFERENCES Where cross references to other parts of this DEP are made, the referenc

32、1.38.01.13-Gen. December 1998 Page 5 2.GENERAL 2.1BOM DESCRIPTION The BOM is a set of engineering documents containing information for identification, fabrication and construction of piping and piping components for a project or part of a project. Index sheets, piping isometrics and material lists m
33、ay be generated either by hand or by means of a computer system. 2.1BOM CONTENTS A BOM shall at least consist of the following documents: -Cover sheet(3.2) -Index sheet(s)(3.3) -Issue sheet(s)(3.4) -Isometric drawings and material lists(3.5) -Key plan (if applicable)(4.) Instructions and requirement
34、s for the piping may necessitate the inclusion of additional sheets, e.g. detail drawings. 2.2STANDARD FORMS In order to compile a BOM, the following forms should be used: General-purpose sheetDEP 31.38.01.44-Gen. Cover sheetDEP 31.38.01.80-Gen. Index sheetDEP 31.38.01.81-Gen. Issue sheetDEP 31.38.0
35、1.82-Gen. Isometric drawing sheetDEP 31.38.01.86-Gen. 2.3NUMBER OF BOMS Separate BOMs shall be issued for different types of material, e.g. carbon steel, low temperature carbon steel, low alloy steel, austenitic stainless steel, ferritic-austenitic stainless steel. Moreover, for lined piping, separa
36、te BOMs shall be made for each type of lining material, e.g. plastic, rubber, cement. There should be no more than about 300 isometrics for each BOM otherwise it becomes unmanageable. If there are more isometrics, more than one BOM shall be made, showing the applicabilityof each BOM on a keyplan (4)
37、. 2.4DRAWING NUMBER, SHEET NUMBER AND FIRST ISSUE All sheets forming part of one BOM shall be identified by one drawing number (taken from the list of drawing numbers allocated to the relevant project) and a sequential sheet number. 2.5FINAL ISSUE All final isometrics of a BOM shall be issued as tra
38、nsparencies or white prints. Independent of the final issue of the completed BOMs, isometric drawing sheets may be issued separately for e.g. inquiry, calculations, authority approval, but this shall then be indicated on the drawing. 2.6COMPUTERISED SYSTEMS Isometrics and material lists produced by
39、computerised systems need not comply with this DEP except that the output of such sysems shall be in according with (3.5). If the isometrics have been drawn in a computer system the final isometrics shall also be delivered electronically in “dxf” format or other format approved by the Principal. DEP
40、 31.38.01.13-Gen. December 1998 Page 6 3.COMPLETION OF FORMS 3.1GENERAL The Contractor is responsible for completing all sheets and forms which form part of the BOMs. All forms and sheets shall be completed in the English language unless otherwise specified by the Principal. Whenever reference is ma
41、de to a drawing or other technical document not forming part of a BOM, the designation number of this drawing/document and its relevant revision letter shall be stated. Each revision, including cancellation of a sheet, shall be indicated by a capital letter, beginning with A and subsequently B, C, e
42、tc. However, the letters I, J and O shall not be used. The revision letter, together with date and signature, shall be stated at the appropriate place. On the sheet concerned, the revision letter shall be given in a triangle near the place where the revision has been made. The revision letter shall
43、be stated on the appropriate line. Cancelled sheets may not be removed from the BOM if they are listed on the index or issue sheet. Sheets that have been cancelled shall be clearly indicated as such by writing or stamping the word CANCELLED across the page. 3.2COVER SHEET (FORM DEP 31.38.01.80-GEN.)
44、 This form shall be fully completed with all the information required. The group number indication shall be in conformance with the key plan (4.) (If applicable). In addition, all processing units or other units, if any, for which piping is included shall be stated. 3.3INDEX SHEET (FORM DEP 31.38.01
45、.81-GEN.) This form shall state all sheets which form part of the relevant BOM, with the exception of the isometric drawings. The numbering of the sheets mentioned on the index sheet shall be from 1 to 100 inclusive. 3.4ISSUE SHEET (FORM DEP 31.38.01.82-GEN.) This form shall state the date of issue
46、of the first issue as well as those of the revision(s) of all sheets of the BOM, including isometric drawings. The columns with the preprinted sheet numbers allow of the addition of a 1, 2, etc., in front of these numbers in order to facilitate the use of this issue sheet for numbers higher than 100
47、. The title block shall be completed accordingly. 3.5ISOMETRIC DRAWINGS AND MATERIAL LISTS Dimensional isometrics shall be made for all piping. Piping shown on the isometric drawing shall be identified by the line number as stated on the engineering flow scheme and piping data sheet. Each pipe spool
48、 shall have a unique number. The number shall consist of the diameter, line number and spool number. Pipe spools shall be numbered following the direction of flow. The maximum dimensions of shop fabricated pipe spools should be within the limits shown in Appendix 2. Dimensions of pipe spools prefabr
49、icated at the construction site shall be determined by local conditions and transport facilities and may exceed the limitations of Appendix 2. The number of the field welds shall be restricted but field welds may be required to limit the dimensions of the pipe spools. DEP 31.38.01.13-Gen. December 1998 Page 7 Consideration shall be given to the application of measuring length at the pipe at the field welds, to allow for construction deviations. For abbreviations and symbols to be used on isometrics see standard drawing S 02.001. Flange bolt holes shall straddle the centre line of the pip
