4、y 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) The Hague, The N
5、etherlands, 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 appropriate they a
6、re 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, oil and gas produ
7、ction 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 where DEPs may not
8、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 Manufacturers/Suppliers use
9、 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 will achieve the s
10、ame 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 Service Agreements p
11、rimarily 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 other Service Comp
12、any. 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/Suppliers under a
13、 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 agreements with
14、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 thereof. The benefit o
15、f 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 not, without the
16、 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 users with the e
17、xpress 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. All administrativ
18、e 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 develops during t
19、heir 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.

It defines m
24、inimum requirements for design and construction of the subjects referred to in (1.2). It is intended for use in oil refineries, chemical plants, gas plants etc. related to manufacturing activities and, where applicable, in exploration and production. Unless otherwise authorized by SIPM, the distribu
25、tion of this specification is confined to companies belonging to or managed by the Royal Dutch/Shell Group, and to contractors nominated by them under cover of a secrecy agreement. As a general rule the requirements of the national and/or local regulations shall be adhered to, but if these are less
26、stringent than the requirements of this specification, the latter shall prevail. Where regulations are more stringent than the requirements of this specification, the supplier and/or contractor shall inform the principal, who may negotiate with the authorities concerned, in order to obtain agreement
27、 to follow this specification as closely as possible. Each section in this specification is self-contained. A sub-section General minimum requirements (1.4), which is applicable to all subjects, is followed by several sections which describe specific requirements for individual subjects. Each sectio
28、n is sub-divided in the following clauses: -detailed scope -general description -functional requirements -design and materials -construction -references. In certain cases, clauses are combined or omitted. Where cross references are made, the number of the section or sub-section referred to is shown
29、in brackets. 1.2SCOPE This specification covers only design and construction of: -roads -paving -surfacing of unpaved areas -cable trenches -erosion protection of slopes, e.g. bund walls, embankments, ditches, open drains, etc. -fencing and gates. The earthworks described herein are limited to those
30、 above the sub-grade, so where a functional minimum requirement for a sub-base/foundation exists, it will be provided without further discussion. Geotechnical and foundation engineering aspects, including stability of slopes, roads, bund DEP 34.13.20.31-Gen. April 1983 Page 4 PDF created with pdfFac
