4、eering Practice) publications reflect the views, at the time of publication, of:Shell Global Solutions International B.V. (Shell GSI)andShell International Exploration and Production B.V. (SIEP)andShell International Chemicals B.V. (SIC)andother Service Companies.They are based on the experience acq

5、uired 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 companies. Where appropriate they are based on, or reference is made to, international, regional, national and

6、industry standards.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, chemical plant, oil and gas production facility, or any other such facility, and thereby to achieve maximum te

7、chnical 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 cover every requirement or diversity of condition at each locality. The system

8、 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 DEPs they shall be solely responsible for the quality of work and the attainme

9、nt 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 same level of integrity as reflected in the DEPs. If in doubt, the Contractor or

10、 Manufacturer/Supplier shall, without detracting from his own responsibility, consult the Principal or its technical advisor.The right to use DEPs is granted by Shell GSI, SIEP or SIC, in most cases under Service Agreements primarily with companies of the Royal Dutch/Shell Group and other companies

11、receiving technical advice and services from ShellGSI, SIEP, SIC or another Group Service Company. Consequently, three categories of users of DEPs can be distinguished:1) Operating companies having a Service Agreement with Shell GSI, SIEP, SIC or other Service Company. The use of DEPs by these opera

12、ting 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 (whether as part of a Service Agreement or otherwise).3) Contractors/subcontractors and Manufacturer

13、s/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 forth in specifi

14、c agreements with users, Shell GSI, 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

15、 thereof, even if it is wholly or partly caused by negligence on the part of Shell GSI, SIEP or other Service Company. The benefit of this disclaimer shall inure in all respects to Shell GSI, SIEP, SIC and/or any company affiliated to these companies that may issue DEPs or require the use of DEPs.Wi

16、thout prejudice to any specific terms in respect of confidentiality under relevant contractual arrangements, DEPs shall not, without the prior written consent of Shell GSI and SIEP, be disclosed by users to any company or person whomsoever and the DEPs shall be used exclusively for the purpose for w

17、hich 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 Shell GSI, SIEP or SIC. The copyright of DEPs vests in Shell GSI and SIEP. Users shall arrange for DEPs to be held in safe cust

18、ody and Shell GSI, SIEP or SIC 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 Shell GSI.TABLE OF CONTENTSPART I GENERAL 51.
