PREFACE DEP (Design and Engineering Practice) publications reflect the views, at the time of publication, of: Shell International Oil Products B.V. (SIOP) and Shell International Exploration a
4、nd 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 processing units and facilities, and they are
5、 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 engineering practice applied by Group compani
6、es 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 publications is provided to users for their con
7、sideration 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 adapt the information set forth in DEPs
8、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 specifically covered, the Principal
9、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 Principal or its technical advisor. The r
10、ight 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 users of DEPs can be distinguished: 1
11、)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 to use DEPs subject to appropriate
12、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 comply with the relevant standards. Subje
13、ct 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 or in connection with the use, applic
14、ation 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 prejudice to any specific terms in respe
15、ct 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 been provided to the user. They shal
16、l 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 any time require information satisfac
17、tory 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). DDDs generally introduce new procedu
18、res 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 replaced by DEPs.

December 1998 Page 3 1.INTRODUCTION 1.1SCOPE This DEP defines the procedures for noise control of plant and equipment. It specifies how to derive maximum allowable noise levels for equ
24、ipment installed in oil refineries, chemical plants, gas plants and, where applicable, in exploration and production facilities and supply/marketing installations. A schematic flow-chart, reviewing the noise control process, is presented in Appendix 1. This DEP applies both to design and constructio
25、n of new plants and to modification of existing plants. This DEP shall be used in conjunction with the referenced standards, which form an integral part of this DEP. Where conflict arises, the requirements of this DEP shall take preference. This DEP is not considered suitable for reference in requis
26、itions of individual equipment. The actual noise limits for the equipment under consideration shall be specified in the equipment requisitions under guidance of the appropriate noise control engineer. This DEP is a revision of the DEP of the same number dated July 1992; a summary of the main changes
27、 since the previous edition is given in (1.5). 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
28、 nominated by them (i.e. the distribution code is “C“, as defined in DEP 00.00.05.05-Gen.). This DEP is intended for use in oil refineries, chemical plants, gas plants and, where applicable, in exploration and production facilities and supply/marketing installations. If national and/or local regulat
29、ions 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 acceptable as regards safety, environmental, economic and legal aspect
30、s. 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 of obtaining ag
31、reement 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. The Principal may undertake
32、 all or 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 and ultimately pays for its design and construction. Th
33、e Principal will 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. 1.3.2Specific definitions Noise levelEither
34、 a sound pressure level, with reference to 20 Pa, or a sound power level, with reference to 1 pW. DEP 31.10.00.31-Gen. December 1998 Page 4 Noise limitA maximum allowable noise level. Noise, fluctuatingNoise whose level varies continuously and to an appreciable extent during the period of observatio
35、n. Noise, impulsiveNoise consisting of one or more bursts of sound energy of duration less than about 1 s. Noise, intermittentNoise whose level abruptly drops to the level of the background noise several times during the period of observation. The time during which the level remains at a constant va
36、lue different from that of the ambient is of the order of 1 s or more. Noise, tonalNoise dominated by one or several clearly distinguishable tones NOTE:All logarithms in this DEP are to a base of 10. 1.4ACTION ITEMS This DEP requires a number of tasks to be performed during a project. These tasks ar
37、e assigned an Action Item (A1, A2, A3 etc.) in the left margin. The responsibility for the execution of these Action Items is assigned to either the Principal or the Contractor as stated in (7), where a summary list of the Action Items is included. 1.5SUMMARY OF MAIN CHANGES This is a revision of th
38、e DEP of the same number dated July 1992. Other than editorial changes, the main changes are as follows: Section 1.1Removal of general reference to EEMUA 140 3.1.2Inclusion of ISO 9613-2 as a model for noise propagation calculations 4.3.5Requirements for flares aligned with DEP 80.45.10.10-Gen. 6.2
39、andInclusion of model format for a Noise Allocation Report Appendix 3 7.4 andInclusion of model format for a Noise Verification Report Appendix 5 1.6CROSS REFERENCES Where cross references to other parts of this DEP are made, the referenced section number is shown in brackets. Other documents refere
40、nced in this DEP are listed in (8). DEP 31.10.00.31-Gen. December 1998 Page 5 2.GENERAL The control of noise in a plant is required for the following reasons: -to conserve the hearing of personnel; -to reduce speech and work interference; -to provide quiet accommodation for personnel; -to prevent an
41、noyance to the neighbouring community. Noise limits can be given for each of the above aspects of noise control, relative to certain areas inside or outside the plant. For the purpose of this DEP they shall be referred to as General Noise Limits. They are specified in (3). Noise limits for each item
42、 of equipment shall be derived from the general noise limits, as applicable for the equipment in its specific position in the plant. They are commonly referred to as Equipment Noise Limits. Procedures for deriving equipment noise limits are specified in (4). Each potential noise source shall be subj
43、ect to the requirements of this DEP. The specified limits shall be met for the design operating conditions of the plant and for otheroperatingconditionswhichoccuroccasionally, suchasstart-up,shutdown, regeneration and maintenance. The only requirement for emergency situations, i.e. any conditions ot
44、her than just described, which can be foreseen or predicted (e.g. relief) is that the absolute limit of (3.2.1) shall not be exceeded. During construction, noise levels should not exceed the limits applicable for operation of the completed plant. DEP 31.10.00.31-Gen. December 1998 Page 6 3.GENERAL N
45、OISE LIMITS 3.1LOCAL REGULATIONS 3.1.1In-plant noise (A1)It shall be investigated whether any local regulations exist with respect to noise in the plant, for example for hearing conservation, speech and work interference, accommodation etc. (A2)For locations where local regulations, statutory requir
46、ements or national standards are more stringent than this DEP, the applicable more stringent limits shall be stated in the project specification, or any other document defining the scope of the project. 3.1.2Environmental noise Limits for environmental noise are not given in this DEP since they will
47、 depend on the local situation. (A3)It shall be investigated whether local regulations exist with respect to environmental noise, which may include noise limits, methods of measurement and/or calculation etc. The interpretation of such regulations shall be discussed with local authorities with the o
48、bject of arriving at agreed environmental noise limits. Environmental noise limits may be different for different times of day or night and for work- days or week-ends. The most stringent of the above requirements shall be the basis of design, taking due account of the period of operation of the pla
49、nt. It shall be ensured that any allowances for occasional higher noise levels that may be acceptable to local authorities are included in the environmental noise limits, e.g. such as for emergencies. (A4)Where local regulations for environmental noise do not exist, this aspect of plant design shall still be considered at the project definition stage to anticipate adverse community reactions at some later date. BS 4142 may be used for guidance. (A5)Authorities usually specify environmental noise limits in terms of maximum allowable sound pressure levels at specified locations
