(SIEP) and Shell International Chemicals B.V. (SIC) The Hague, The Netherlands, and other Service Companies. They are based on the experience acq
5、uired 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 to, national and international standards an
6、d 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 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 syste
8、m 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 attain
9、ment 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 re
11、ceiving 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 f
13、or 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 any
14、 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 c
15、ompany 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 company
16、 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 in
17、 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 addit
18、ion 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 ap
19、plicable to Standard Specifications and DDDs. Standard Specifications and DDDs will gradually be replaced by DEPs. DEP 32.71.00.12-Gen.

April 1993 Page 3 PDF created with pdfFactory Pro trial version 1.INTRODUCTION 1.1SCOPE This is a new DEP giving the minimum requirements for equipment and systems used for offsho
25、re telecommunications and provides guidance for the selection and specification of equipment and systems meeting these requirements. It supplements DEP 32.71.00.10- Gen. and DEP 32.71.00.11-Gen. Minimum requirements for telecommunications for offshore platforms with living quarters are normally spec
26、ified by local regulatory authorities. Telecommunication systems for a specific offshore platform can rarely be considered in isolation because they normally form part of a total telecommunications network. Significant considerations are telecommunications between other offshore platforms in the sam
27、e or nearby fields and with the onshore infrastructure. Since the requirements vary from country to country this manual can give general guidance only. 1.2DISTRIBUTION, INTENDED USE AND REGULATORY CONSIDERATIONS Unless otherwise authorised by SIPM, the distribution of this DEP is confined to compani
28、es forming part of the Royal Dutch/Shell Group or managed by a Group company, and to Contractors nominated by them (i.e. the distributioncode is “C“, as describedin DEP 00.00.05.05-Gen.). This DEP is intended for use in oil and gas production facilities. If national and/or local regulations exist in
29、 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 acceptable as regards safety, environmental, economic and legal aspects. In all cas
30、es 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 of obtaining agreement to fol
31、low 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. The Principal may undertake all or part o
32、f 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 and ultimately pays for its design and construction. The Principal wi
33、ll generally specify the technical requirements. The Principal 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. DEP 32.71.00.12-Gen. April 1993 Page 4 PDF created with p

An A60 firewall is a barrier defined in SOLAS which will withstand a non-hydrocarbon fire for 60 minutes. A complex is two or more platforms connected by a permanent bridge or walk
35、way. A hazardous area, 426-03-01, IEC 50 is an area in which an explosive gas atmosphere is or may be expected to be present in quantities such as to require special precautions for the construction, installation and use of electrical apparatus. A manned platform is continuously occupied by persons
36、accommodated and living thereon. Mandatorytelecommunicationsequipmentis that required by national and local regulations. A muster station is the normal place where personnel await evacuation from the platform. A non-hazardous area, 426-03-02, IEC 50 is an area in which an explosivegas atmosphere is
37、not expected to be present in quantities such as to require special precautions for the construction, installation and use of electrical apparatus. A platform is an offshore structure standing on the sea-bottom or permanently anchored to it. The safety case is a demonstration that the hazards of an
38、installation have been identified and assessed and are under control and that the exposure of personnel to these hazards has been minimised. For offshore platforms an important feature is a demonstration that the arrangements are made for refuge and evacuation of personnel in the event of an emergen
39、cy. The sea area is the area of the sea in which the platform is located. Sea areas A1, A2, A3, and A4 are defined in the GMDSS amendments to the SOLAS convention. The temporary refuge provides a place where personnel can muster without undue risk while having access to the communications, monitorin
40、g and control equipment necessary to ensure their personal safety and from which, if necessary, safe and full evacuation can be effected. Type approval is the permissionto connect a specific type of telecommunication equipment to the public network. The permission is usually only granted after tests
41、 to ensure e.g. safety, acceptable spurious radiation, interworking with other equipment, etc. The certificate granted after such tests is the type approval certificate. An unmanned platform has no living accommodation or quarters provided. 1.4ABBREVIATIONS AC-Alternating current CCR-Central control

April 1993 Page 6 PDF created with pdfFactory Pro trial version 2.GENERAL 2.1PURPOSE OF TELECOMMUNICATIONS Telecommunication facilities may be grouped and prioritised as follows: -safety telecommunications for compliance with the Principals safety philosophy and mandatory national and l
46、ocal regulations; -operational telecommunications to enhance the efficiency of offshore operations; -non-essential telecommunications to enhance personnel welfare and recreation, and provide administrative data systems. 2.1.1Mandatory telecommunications Telecommunications systems specifically design
47、ated as mandatory for safety reasons include the public address and general alarm system, equipment to operate on the international maritime distress frequencies, aeronautical band radios. The specifications of mandatory equipment are often covered by official regulations. 2.1.2Operational telecommu
48、nications Certaintelecommunications systemsare providedspecifically to support production operations. These include facilities such as the ability to monitor operations from shore and to give assurance of the integrity of pipelines. Operational telecommunications should be typified by high availabil
49、ity and reliability with monitoring of the system to give an early indication of failure. However, temporary loss of operational telecommunications should not, on its own, be a reason to shut down oil and gas facilities. 2.1.3Non-essential telecommunications The welfare aspects of telecommunications apply to installations with LQs and include the provision of audio and video entertainment systems, and facilities to allow personnel on board to telephone home. Administrative data systems
