4、d with pdfFactory Pro trial version PREFACE DEP (Design and Engineering Practice) publications reflect the views, at the time of publication, of: Shell International Oil Products B.V. (SIOP) and Shell International Exploration and Production B.V. (SIEP) and Shell International Chemicals B.V. (SIC)
5、The Hague, The Netherlands, and other Service Companies. They are based on the experience acquired during their involvementwith the design, construction, operation and maintenance of processing units and facilities, and they are supplemented with the experience of Group Operating companies. Where ap
6、propriate they are based on, or reference is made to, national and international standards and codes of practice. The objective is to set the recommendedstandard for good design and engineeringpractice applied by Group companies operating an oil refinery, gas handling installation, chemical plant, o
7、il 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 publications is provided to users for their consideration and decision to implement. This is of particular importance whe
8、re 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 adapt the information set forth in DEPs to their own environment and requirements. When Contractors or Manufacture
9、rs/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 not specifically covered, the Principal will expect them to follow those design and engineering practices which wi
10、ll 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 Principal or its technical advisor. The right to use DEPs is granted by SIOP, SIEP or SIC, in most cases under Serv
11、ice 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 of users of DEPs can be distinguished: 1)Operating companies having a Service Agreement with SIOP, SIEP, SIC or ot
12、her 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 authorized to use DEPs subject to appropriate contractual arrangements. 3)Contractors/subcontractors and Manufacturers/S
13、uppliers 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 comply with the relevant standards. Subject to any particular terms and conditions as may be set forth in specific
14、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 of or in connection with the use, application or implementation of any DEP, combination of DEPs or any part thereo
15、f. 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 prejudice to any specific terms in respect of confidentiality under relevant contractual arrangements, DEPs shall
16、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 have been provided to the user. They shall be returned after use, including any copies which shall only be made by
17、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 at any time require information satisfactory to them in order to ascertain how users implement this requirement. A
18、ll 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 (DDDs). DDDs generally introduce new procedures or techniques that will probably need updating as further experience d
19、evelops 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 be replaced by DEPs. DEP 32.31.00.10-Gen. July 1985 Page 2 PDF created with pdfFactory Pro trial version TABLE O

July 1985 Page 3 PDF created with pdfFactory Pro trial version 1.INTRODUCTION 1.1GENERAL This manual describes project engineering procedures for the design, requisitioning, testing and inspection of instruments. It replaces Section 5 of DEP 32.31.00.31-Gen., Instrument Engine
24、ering-General dated July 1970. Some of the sections of this DEP are already covered by other publications and the remainder are being reconsidered in documents currently in hand, i.e. Sections 8, 9 and 11. Consequently DEP 32.31.00.31-Gen., is being withdrawn at this time, since its contents no long
25、er reflect current practices in those sections which are being revised. For any queries that arise on this subject the principal should be consulted. The procedures are intended for use in oil refineries, chemical plants, gas plants and, where applicable, in exploration, production and new ventures.
26、 Unless otherwise authorized by SIPM, the distributionof this manual is confined to companies belonging to or managed by the Royal Dutch/Shell Group, and to contractors nominated by them. All publications referred to in this manual are listed in Section 10. Where cross references are made, the numbe
27、r of the section or sub-section referred to is shown in brackets. 1.2DEFINITIONS For the purpose of this manual the following definitions shall hold: Shall and Should - the word shall is to be understood as mandatory and the word should as strongly recommended to comply with the requirements of this
28、 manual. The Principal* is the party which initiates the project and ultimately pays for its design and construction. The Principal will generally specify the technical requirements. The Principal may also include an agent or consultant, authorized to act for the Principal. The Contractor is the par
29、ty which carries out all or part of the design, engineering, procurement, construction and commissioning for the project. The Principal may sometimes undertake all or part of the duties of the Contractor. The Manufacturer/Supplier is the party which manufactures or supplies equipment and services to
30、 perform the duties specified by the Contractor. *For operating companies having a service agreement with SIPM or SICM the principal shall be taken as SIPM- MFEE/41. DEP 32.31.00.10-Gen.
