Neither the whole nor any part of this document may be disclosed to any third party without the prior written consent of Shell International Oil
2、Products B.V. and Shell International Exploration and Production B.V., The Hague, The Netherlands. The copyright of this document is vested in these companies. All rights reserved. Neither the whole nor any part of this document may be reproduced, stored in any retrieval system or transmitted in any
3、 form or by any means (electronic, mechanical, reprographic, recording or otherwise) without the prior written consent of the copyright owners. PREFACE DEP (Design and Engineering Practice) publications reflect the views, at the time of publication, of: Shell International Oil Products B.V. (SIOP) a
4、nd 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 involvement with the design, construction, operation and maintenance of processin
5、g 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 objective is to set the recommended standard for good design and engineeri
6、ng 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 benefit from standardization. The information set forth in these publication
7、s 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 to be sufficiently flexible to allow individual operating companies to adap
8、t 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 design and engineering standards. In particular, for those requirements not
9、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/Supplier shall, without detracting from his own responsibility, consult the Princ
10、ipal 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 advice and services from SIOP, SIEP or SIC. Consequently, three categories of u
11、sers 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 conditions of the relevant Service Agreement. 2)Other parties who are authorized
12、 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 supplied or - generally - work performed on behalf of the said users compl
13、y 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 injury or death) suffered by any company or person whomsoever as a result of o
14、r 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 these companies that may issue DEPs or require the use of DEPs. Without prej
15、udice 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 and the DEPs shall be used exclusively for the purpose for which they have
16、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 shall arrange for DEPs to be held in safe custody and SIOP or SIEP may at a
17、ny 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 there are Standard Specifications and Draft DEPs for Development (DDDs).
18、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 Specifications and DDDs. Standard Specifications and DDDs will gradually be
19、replaced by DEPs. DEP 30.10.05.11-Gen.

23、E This DEP specifies requirements and gives recommendations for: 1.Block models. 2.3D-CAD visualisation and use of 3D-CAD features. 3.Physical models. 4.Model review sessions. This is a revision of the DEP of the same number, dated June 1988, which had the title “Model construction for processing un
24、its“. 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIOP and SIEP, the distribution of this DEP is confined to companies forming part of the Royal Dutch/Shell Group or managed by a Group company, and to Contractors nominated by them (i.e. the distribution
25、 code is “C“, as defined in DEP 00.00.05.05-Gen.). This DEP is intended to be used in oil refineries, chemical plants, gas plants, exploration and production facilities and supply/marketing installations and for specific items such as storage facilities and/or jetties, road/rail loading facilities a
26、nd complicated manifolds. If national and/or local regulations exist in which some of the requirements may be 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 acceptabl
27、e as regards safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the Principal of any deviations from the requirements of this DEP which are considered to be necessary in order to comply with national and/or local regulations. The Principal may then negotiate
28、with the Authorities concerned with the object of obtaining agreement to follow this document as close as possible. 1.3DEFINITIONS 1.3.1General The Contractor is the party which carries out all or part of the design, engineering, procurement, construction, commissioning or management of a project or
29、 operation of a facility. The Principal may undertake all or a part of the duties of the Contractor. The Manufacturer/Supplier is the party which manufactures or supplies equipment and services to perform the duties specified by the Contractor. The Principal is the party which initiates the project
30、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 the Principal. The word shall indicates a requirement. The word should indicates a recommendation. 1.3.2S

July 1996 Page 5 2.GENERAL In the course of conceptual engineering a block model should first be constru
33、cted. At a later stage a 3D-CAD model or a physical model should be constructed. A block model should be used to establish the location of buildings, main equipment and main pipe routings in the unit. The physical models and 3D-CAD models should provide a visual check on safety, operability and main
34、tainability and facilitate the engineering and erection of the units, which may result in a cost reduction. They may also be used for the training of operators and for the planning of efficient maintenance schedules, and to assist construction work (e.g. handling of heavy or large equipment). A 3D-C
35、AD system is a design tool for the Contractor and an integral part of the design and engineering process. The visualisation used for the 3D-CAD “model review“ is only one of the features of a 3D- CAD system. DEP 30.10.05.11-Gen. July 1996 Page 6 3.BLOCK MODEL 3.1GENERAL The block model should be use
36、d for evaluating different lay-out options and to establish the location of main equipment and the main pipe routings in the unit, taking into account the required safety distances and accessibility for construction, operation and maintenance. After approval of the lay-out by the Principal, it can b
37、e used as a basis for preparing a more detailed (initial) plot plan drawing. The block model should be used as the basis on which a 3D-CAD model or a physical model will be developed. For the scope and organisation of a block model review, see (6.2 and 7.2). 3.2CONSTRUCTION The block model should co
38、nsist of wooden or plastic blocks, representing in a simplified form the equipment, e.g. columns, heat transfer equipment, vessels, reactors, heaters, pumps. The equipment numbers may be indicated. Main pipe racks, structures, the control centre, analyser houses, switch houses and other buildings sh
39、ould also be shown. The types of buildings should be indicated. The scale should be 1:100. For offshore installations the scale should be 1:50 or 1:331/3. Alternatives scales may be used if approved by the Principal. Plant north, true north, scale and, if applicable, the table number of the block mo
40、del shall be indicated on the base plate. For the lay-out of the model, basic plant lay-out studies and piping studies shall be made if required. These studies will also establish pipe track widths, structures, etc. The routing of main electrical and instrument cable trenches should be shown. DEP 30
41、.10.05.11-Gen. July 1996 Page 7 4.3D-CAD MODEL 4.1GENERAL The 3D-CAD model is a collection of graphical data which describes the facilities of a plant for visualisation purposes. The 3D-CAD model can be accessed via a 3D-CAD system. The graphical data is often an integral part of an engineering data
42、base supporting the design process. An important advantage of a 3D-CAD engineering database is the possibility to maintain consistency between the produced documents and to assist the co-ordination of work between different disciplines. It enables the Contractor to integrate the different design sta
43、ges and the different subjects, such as piping, foundations, table tops, steel structures, equipment, instrumentation, electrical equipment, and HVAC equipment into one 3D-model. Typical deliverables of a 3D-CAD system include: -Detailed engineering drawings such as plan and elevation drawings, bird
44、s-eye views, etc. -Piping isometrics. -Material Take-off (Bills of Material). -Shaded perspective views separated in logical areas, e.g. units (model review). -Reports such as line lists, instrument data, interference checks (clashes), mock-ups. 4.2SAFETY, OPERATIONAL AND MAINTENANCE ASPECTS The CAD
45、 system shall be structured in such a way that all disciplines involved can check whether sound design and engineering criteria have been met with respect to safety, ergonomics, operability and maintenance. This should include accessibility for maintenance and fire fighting, location of valves, cons
46、tructability, process instrumentation, routing of the piping adequate for the process, location of emergency shut-down stations, proper and safe location of vents and drains, location of fire protection and fire-fighting equipment and escape routes. 4.3CONSTRUCTION OF THE PROCESS UNIT A 3D-CAD syste
47、m should be made available at site, to provide information during construction for aspects such as transport and erection of equipment, the routing of piping, positioning of structural steel, platforms, cable trenches, trunking and channels. 4.4INSTRUCTION The 3D-CAD model may be used for training a
48、nd instruction of plant operators, construction staff, maintenance staff and emergency response organisation. 4.5MODEL REVIEW FEATURES WITH 3D-CAD TECHNOLOGY The required features shall be agreed between the Principal and the Contractor before the set-up of the 3D-CAD system and engineering database
49、 is started. The 3D-CAD system should be programmed to provide reports regarding situations where certain criteria are not met. This approach can substantially improve the efficiency of the model review. Presently, the application of 3D-CAD technology allows for the following: Definition of classified 3D-shapes to indicate envelopes for: -Safety. -Area classification zones. -Head room/tripping hazards. -Access/escape corridors. -Valve hand wheels. -Reach/clearances for activities.
