The copyright of this document is vested in Shell Internationale Petroleum Maatschappij B.V., The Hague, the Netherlands. All rights reserved. Neither the whole nor any part of this docum
3、ent may be reproduced, stored in any retrieval system or transmitted in any form or by any means (electronic, mechanical, reprographic, recording or otherwise) without the prior written consent of the copyright owner. PREFACE DEP (Design and Engineering Practice) publications reflect the views, at t
4、he 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 Netherlands, and other Service Companies. They are based on the experience acquired during their involve
5、ment with 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 are based on, or reference is made to, national and international standards and codes of practice. The
6、objective is to set the recommended standard for good design and engineering 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 be
7、nefit 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 cover every requirement or diversity of condition at each locality. The system of DEPs is expected t
8、o 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 DEPs they shall be solely responsible for the quality of work and the attainment of the required de
9、sign 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 same level of integrity as reflected in the DEPs. If in doubt, the Contractor or Manufacturer/Supplie
10、r 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 primarily with companies of the Royal Dutch/Shell Group and other companies receiving technical advic
11、e 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 Company. The use of DEPs by these Operating companies is subject in all respects to the terms and condit
12、ions 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 contract with users referred to under 1) or 2) which requires that tenders for projects, materials
13、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 users, SIOP, SIEP and SIC disclaim any liability of whatsoever nature for any damage (including inju
14、ry 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 of this disclaimer shall inure in all respects to SIOP, SIEP, SIC and/or any company affiliated to th
15、ese 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 prior written consent of SIOP and SIEP, be disclosed by users to any company or person whomsoever a
16、nd 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 express prior written consent of SIOP and SIEP. The copyright of DEPs vests in SIOP and SIEP. Users s
17、hall 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 administrative queries should be directed to the DEP Administrator in SIOP. NOTE: In addition to DEP publications
18、 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 their use. The above requirements for distribution and use of DEPs are also applicable to Standard Sp
19、ecifications and DDDs. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 31.29.80.30-Gen.

43、Gen. October 1994 Page 7 2.BASIC REQUIREMENTS 2.1APPLICABLE STANDARD It is intended that engines shall be designed and supplied generally in accordance with ISO 3046 parts 1 to 7. This DEP provides specific requirements amplifying the requirements of the International Standard. 2.2RANGE OF APPLICATI
44、ON The driven machines will include alternators, pumps (including firewater pumps) and compressors in a variety of duties. The engine will in general be supplied to a packager who will undertake the packaging of the engine into a complete unit to fulfil the Principals requirement for electric power
45、or fluid movement. The engines will be in continuous or intermittent use in vital or non-vital service as described in the requisition. The engine shall be suitable for continuous unattended baseload operation for 24 hours per day at the extremes of ambient conditions given in the requisition. (A1)E
46、ngines in vital service shall be guaranteed by the Manufacturer to be able to accept full load within 10 seconds of receiving the starting signal. Any shorter period required on a specific project will be given in the requisition. The fuel specification will be given in the requisition; the Manufact
47、urer shall guarantee that the fuel is suitable for the engine at the service power. See also (3.4.1). If the Manufacturer proposes a turbocharged version of an engine originally developed for natural aspiration, the suitability of the engine to meet the operating requirements shall be demonstrated b
48、y means of design calculations and service references. 2.3POWER OUTPUT, FUEL AND LUBRICANT CONSUMPTION The service power of the engine in accordance with ISO 3046-1 shall be the continuous power available at the drive coupling of the engine after deduction of all engine driven auxiliaries. The Manuf
49、acturer shall state the auxiliaries driven by the engine and their power absorbed in computing the rated power. Engine driven fuel and lubricating oil pumps and separate lubricators for valve gear or cylinders are regarded as engine components and not auxiliaries within the context of the declaration of power per ISO 3046-1. The ISO power is to be derated to the service power at the most severe ambient conditions under which the engine will operate. The service power of the engine as defined in ISO 3046-1 shall be not less than 110% of the maximum power required by the driven equipment un
