PREFACE DEP (Design and Engineering Practice) publications
4、 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 Netherlands, and other Service Companies. They are based on the experience acqui
5、red 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, national and international standards and
6、 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, chemical plant, oil and gas production facility, or any other such facility, and thereby to achieve maximum t
7、echnical 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 syst
8、em 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 attai
9、nment 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
10、 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 primarily with companies of the Royal Dutch/Shell Group and other companies r
11、eceiving 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 Company. The use of DEPs by these Operating companies is subject in all respects
12、 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 contract with users referred to under 1) or 2) which requires that tenders
13、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 users, SIOP, SIEP and SIC disclaim any liability of whatsoever nature for an
14、y 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 of this disclaimer shall inure in all respects to SIOP, SIEP, SIC and/or any
15、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 prior written consent of SIOP and SIEP, be disclosed by users to any compan
16、y 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 express prior written consent of SIOP and SIEP. The copyright of DEPs vests i
17、n 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 administrative queries should be directed to the DEP Administrator in SIOP. NOTE: In addi
18、tion 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 their use. The above requirements for distribution and use of DEPs are also a
19、pplicable to Standard Specifications and DDDs. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 37.92.10.31-Gen.

October 1994 Page 4 PART IINTRODUCTION 1.1SCOPE This new
28、DEP gives the minimum requirements for pedestal cranes for use on fixed offshore platforms when Lloyds Register of Shipping “Code for Lifting Applications in a Marine Environment“ and BS 2573 are specified as the applicable external standards. It is intended they shall be used together with this DEP
29、 for the design, procurement, manufacture, testing and inspection of Pedestal Cranes for offshore production and drilling platforms for Group company operations. NOTE:The scope of this DEP does not cover cranes for floating structures nor those for handling manned submersibles in offshore conditions
30、. The crane shall satisfy the condition for the LRS code (as amended/supplemented by Part II of this DEP). Where steels with higher strength properties than those depicted in the LRS code are proposed by the Manufacturer, the design requirements of BS 2573 Part I (as amended/supplemented by Part III
31、 of this DEP) shall be satisfied. Mechanisms shall be designed to satisfy the conditions of BS 2573 Part 2 (as amended/supplemented by Part III of this DEP). DEP 37.92.10.30-Gen.gives theminimumrequirementsforpedestal craneswhen API Spec 2C is specified as the applicable external standard. A-1The ch
32、oice of external standard shall be determined by the Principal depending upon national/local regulations and will be defined in the project specifications. 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIPM, the distribution of this DEP is confined to com
33、panies forming part of the Royal Dutch/Shell Group or managed by a Group company, and to Contractors and Manufacturers/Suppliers nominated by them. (i.e. the distribution code is “F“ as defined in DEP 00.00.05.05-Gen.). This DEP is intended for use in oil and gas production facilities. If national a
34、nd/or local regulations exist in which some of the requirements are more stringent than in this DEP the Contractor shall determine by careful scrutiny which of the requirements are the more stringent and which combination of requirements will be acceptable as regards safety, environmental, economic
35、and legal aspects. In all cases the Contractor shall inform the Principal of any deviation from the requirements of this DEP which is considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate with the Authorities concerned with the object
36、of obtaining agreement to follow this DEP as closely as possible. 1.3DEFINITIONS 1.3.1General definitions The Contractor is the party which carries out all or part of the design, engineering, procurement, construction, commissioning or management of a project or operation of a facility.
