(SIEP) and Shell International Chemicals B.V. (SIC) The Hague, The Netherlands, and other Service Compa
5、nies. They are based on the experience acquired during their involvementwith 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 t
6、o, national and international standards and codes of practice. The objective is to set the recommendedstandard for good design and engineeringpractice applied by Group companies operating an oil refinery, gas handling installation, chemical plant, oil and gas production facility, or any other such f
7、acility, 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 importance where DEPs may not cover every requirement or diversit
8、y 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 or Manufacturers/Suppliers use DEPs they shall be solely responsi
9、ble 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 practices which will achieve the same level of integrity as reflected
10、 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 cases under Service Agreements primarily with companies of the Roya
11、l 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, 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. 3)Contractors/subcontractors and Manufacturers/Suppliers under a contract with users referred to un
13、der 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 specific agreements with users, SIOP, SIEP and SIC disclaim
14、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 thereof. The benefit of this disclaimer shall inure in al
15、l 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 arrangements, DEPs shall not, without the prior written consent of SIOP and
16、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 only be made by users with the express prior written consent of SIO
17、P 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 requirement. All administrative queries should be directed to the
18、 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 further experience develops during their use. The above requirements fo
19、r distribution and use of DEPs are also applicable to Standard Specifications and DDDs. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 37.17.10.11-Gen.

25、UCTION 1.1SCOPE This new DEP provides requirements and guidelines for the design and performance of an offshore Temporary Refuge (TR) and the associated means of escape and evacuation. This DEP defines the objective of the TR and the associated means of escape and evacuation. It describes the concep
26、t of the TR and the systems and subsystems which comprise the TR and their acceptance criteria. Guidance on how to meet the objectives is also given. 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIPM, the distribution of this DEP is confined to companies
27、 forming part of the Royal Dutch/Shell Group or managed by a Group company and to Contractorsnominatedby them(i.e.thedistributioncode isC as describedin DEP 00.00.05.05-Gen.). This DEP is intended for use in offshore oil and gas exploration and production facilities: -new and existing; -manned and n
28、ot normally manned; and -fixed and mobile. 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 wil
29、l be acceptable as regards safety, environmental, economic 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 the
30、n negotiate with the Authorities concerned with the object 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 manage
31、ment of a project or operation of a facility. The Principal may undertake all or part of the duties of 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 Prin
32、cipal may also include an agent or consultant authorised to act for, and on behalf of, the Principal. The word shall indicates a requirement. The word should indicates a recommendation. 1.3.2Specific definitions Acceptance criteria - requirements against which the fulfilment of an objective can be m

March 1994 Page 7 PDF created with pdfFactory Pro trial version 2.GENERAL REQUIREMENTS 2.1PRIMARY OBJECTIVE Every off
45、shore installation should have a TR. The objective of the TR and its associated access and evacuation routes and embarkation areas is to secure the safety of persons on board (POB) in the event of a major incident affecting the installation. The system provides a secure location to enable POB to mus
46、ter and possibly “sit-out“ the incident; it also provides security during escape to the TR and subsequent evacuation from the TR to the point of embarkation. 2.2FUNCTIONAL REQUIREMENTS The main function of the TR shall be to provide a place where the total POB can muster without undue risk and still
47、 have access to the communications, monitoring and control equipment necessary to ensure their personal safety, and from where, if necessary, safe and complete evacuation can be effected. The functions of the escape and evacuation routes and the embarkation areas are the provision, without undue ris
48、k to POB, of: -secure means of escape to the TR; and -secure means for a complete evacuation from the TR. 2.3DESIGN BASIS The measures required to meet the objectives and acceptance criteria are installation specific and shall cover the range of major incident scenarios which are applicable to it. T
49、he HMP (6.2) should be used to identify and manage the range of major incident scenarios. Two categories of acceptance criteria are defined. These are: -Conditions required for integrity (5.1); -Endurance period (5.2) - the period of time for which the conditions required for integrity shall be maintained. The design of the TR shall be considered in relation to the overall design of the installation so as to achieve the optimum design. In particular
