Neither the whole nor any part of this document may be reproduced, stored in any retrieval system or transmitted in any form or by any means (electronic, mechanical, reprographic, recording or otherwise) without t

(SIOP) and Shell International Exploration and Production B.V. (SIEP) and Shell International Chemicals
5、 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 processing units and facilities, and they are supplemented with the experience of Group Operating compan
6、ies. 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 engineering practice applied by Group companies operating an oil refinery, gas handling installation, ch
7、emical 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 publications is provided to users for their consideration and decision to implement. This is of particular
8、 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 adapt the information set forth in DEPs to their own environment and requirements. When Contractors
9、 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 not specifically covered, the Principal will expect them to follow those design and engineering pra
10、ctices 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 Principal or its technical advisor. The right to use DEPs is granted by SIOP, SIEP or SIC, in most c
11、ases 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 of users of DEPs can be distinguished: 1)Operating companies having a Service Agreement with SIOP,
12、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 authorized to use DEPs subject to appropriate contractual arrangements. 3)Contractors/subcontractors and
13、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 comply with the relevant standards. Subject to any particular terms and conditions as may be set for
14、th 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 of or in connection with the use, application or implementation of any DEP, combination of DEPs or
15、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 prejudice to any specific terms in respect of confidentiality under relevant contractual arrangemen
16、ts, 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 have been provided to the user. They shall be returned after use, including any copies which shall o
17、nly 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 at any time require information satisfactory to them in order to ascertain how users implement this
18、 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 (DDDs). DDDs generally introduce new procedures or techniques that will probably need updating as furth
19、er 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 be replaced by DEPs. DEP 31.29.60.32-Gen. October 1992 Page 2 TABLE OF CONTENTS PART IINTRODUCTION

October 1992 Page 3 PART IINTRODUCTION 1.1SCOPE This DEP is a revision of that with the same n
22、umber and title dated September 1983 and contains the minimum technical requirements for lubricating oil, seal oil and control oil supply systems for special-purpose applications. These systems may serve compressors, centrifugal pumps, special-purpose steam turbines, gas turbines, expanders, gears a
23、nd electric motors. This DEP is based on API Standard 614, second edition, January 1984. Part II of this specification amends, supplements and deletes various clauses/paragraphs of API Standard 614. Clauses of API Standard 614 which are not mentioned in this specification remain applicable as writte
24、n. This specification shall be used in conjunction with the data/requisition sheet relevant to the equipment it serves. Equipment covered by this DEP shall comply with API 614, as amended and supplemented by this DEP. 1.2DISTRIBUTION, APPLICABILITY AND REGULATORY CONSIDERATIONS Unless otherwise auth
25、orised by SIPM, the distribution of this document is confined to companies forming part of or managed by the Royal Dutch/Shell Group, and to Contractors and Manufacturers nominated by them (i.e. the distribution code is “F“ as defined in DEP 0.00.05.05-Gen.). This DEP is intended for use in oil refi
26、neries, chemical plants, gas plants, and exploration and production facilities. If national and/or local regulations exist in which some of the requirements are more stringent than in this manual, the contractor shall determine by careful scrutiny which of the requirements are the more stringent and
27、 which combination of requirements will be acceptable as regards safety, economic and legal aspects. In all cases the contractor shall inform the Principal of any deviation from the requirements of this document which is considered to be necessary in order to comply with national and/or local regula
28、tions. The Principal may then negotiate with the authorities concerned with the object of obtaining agreement to follow this document as closely as possible. 1.3DEFINITIONS For the purpose of this DEP, the following definitions shall hold: The Contractor is the party which carries out all or part of
29、 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. TheManufacturer/Supplier/Vendoristhepartywhichmanufacturesorsupplies equipment and services to perform th
30、e 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 requirements. The Principal may also include an agent or consultant authorised to act for, and on behal
31、f of, the Principal. The word Shall indicates a requirement. The word Should indicates a recommendation. 1.4CROSS-REFERENCES Where cross-references are made, the number of the part, section or subsection referred to is shown in brackets. All referenced standards invoked by this DEP are listed in Par
32、t III. 1.5ACTION ITEMS A bullet () in the margin before certain clauses (paragraphs) in API Std 614 indicates that alternative requirements are possible and a decision by the purchaser is required or that DEP 31.29.60.32-Gen. October 1992 Page 4 further information is to be provided by the purchaser
33、. This decision/information shall be indicated by the Principal in the space provided for in the data/requisition sheet. In some cases these decisions have already been made by the amendment to the API clause (paragraph) in this DEP, effectively eliminating the bullet. In other cases this DEP consid
34、ers the specific option as not normally required or recommended. In other cases this DEP does not address the specific bullet and the Principal is responsible for making the decision or providing the required information. Also, some amendments in this DEP have created additional items, where a decis
35、ion from the Principal is required. A summary of these three categories of bullets is shown below: CATEGORY ACATEGORY BCATEGORY C 1.1.22.12.32.1.51.6.2 2.1.22.12.52.3.92.1.2.2 2.1.142.12.62.4.182.1.2.4 2.1.162.13.92.5.52.1.4 2.2.12.13.12.22.5.62.1.6 2.3.6.g2.13.132.6.32.1.9 2.3.83.2.12.6.42.1.11 2.3
