4、ww.eemua.orgTHE ENGINEERING EQUIPMENT AND MATERIALS USERS ASSOCIATION The Engineering Equipment and Materials Users Association (EEMUA) was formed in 1983 by the Amalgamation of the Oil Companies Materials Association (OCMA) and the Engineering Equipment Users Association (EEUA). It is an organisati

5、on of substantial purchasers and users of engineering products, whose members include leading national and multinational companies in the petroleum, gas, chemical and energy industries, and engineering contractors that act on behalf of those companies as their main agents. EEMUA is concerned with th

6、e design, installation, operation and maintenance of the engineering plant used by members in pursuing their business activities. The Association aims to reduce members costs by providing the opportunity for them to share resources and expertise in order to keep abreast of technological developments

7、 and improve the effectiveness and efficiency of their engineering activities. EEMUA supports the British Standards Institution, works with other institutions, associations, government departments, regulatory authorities and the Confederation of British Industry, and is also actively involved with o

8、ther standards-making bodies, both national and international, such as the American Petroleum Institute. EEMUA work is carried out in-house by members or with the help of other organisations, and may lead to the production of Association publications. These are prepared primarily for members use, bu

9、t are usually offered for sale and thus for more general use. Such publications may also be submitted, normally through the British Standards Institution, as bases for appropriate national, European or international standards. Members of EEMUA include: ABB Engineering Services, Associated Octel, Ast

10、raZeneca, BASF, BP, ChevronTexaco, ConocoPhillips, Dow Corning, E.ON UK, ExxonMobil, Foster Wheeler Energy, Huntsman, Hydro, Johnson Matthey, Royal Vopak, RWE Npower, Shell, Syngenta and Total iiiii ABOUT THIS PUBLICATION: LEGAL ASPECTS In order to ensure that nothing in this publication can in any

11、manner offend against or be affected by the provisions of the Restrictive Trade Practices Act 1976, the recommendations which it contains will not take effect until the day following that on which its particulars are furnished to the Office of Fair Trading.

41、ATIONS.(End) viii 1 FOREWORD GENERAL Although pressure vessel designers have several codes from which to choose, no standard or guidance document specifically encompassing the design and installation of mounded storage vessels has been generally available. EEMUAs Storage Tanks Technical Committee ha

42、s for some time been aware of this need, and has accordingly developed the present document. The integrity of a pressure vessel depends on both its strength and the adequacy of the supporting foundation or structure. For vessels on earth foundations, with their inherent proneness to settlement, this

43、 aspect is of greater importance than for those more conventionally supported. For this reason, considerable coverage is given in this guide to soil investigation and foundation design. IMPACT OF THE EUROPEAN PRESSURE EQUIPMENT DIRECTIVE thThe European Pressure Equipment Directive (PED) became manda

44、tory on 30 May 2002 following a 2-year transitional period in which compliance was optional. Pressure equipment placed on the market and/or put into service in the European Economic Area (EEA) must now comply with the requirements of that Directive, which has been transposed by individual Member Sta

45、tes into statutory regulations. Switzerland has also adopted the Directive. REFERENCES AND ABBREVIATIONS A listing of documents referred to in the main text and appendices, and recommended literature for further reading are given in Section 7, and a glossary of abbreviations in Section 8. NOTE ON TH

46、E PRESENT (2005) REPRINT This reprint incorporates Errata dated Oct. 2003, Amendments No 1 dated Nov 2004, and further amendments, largely of an editorial nature. Principal changes, including some renumbering of subsections and inclusion of additional headings, are indicated either by sidelines or b

47、y grey highlighting. The changes previously advised in the Errata and Amendments No 1 are not so indicated. Section 6, Guidelines for In-Service Inspection, has been extensively restructured, now incorporating what were previously the latter subsections of Section 5; also, Appendix F, Manufacturing

48、Report, has been deleted as being too rigid in its advice on the layout of a manufacturing report. The appendices have not, however, been renumbered. 2 1 INTRODUCTION AND SCOPE 1.1 INTRODUCTION In the context of the present document, mounded storage is the term given to the pressurised storage at am

49、bient temperatures of liquefied petroleum gases in horizontal cylindrical vessels placed at or just below ground level and completely covered with suitable backfill. Several vessels may be placed side by side under one mound. Mounded storage installations, which have many advantages over alternative designs (see 2.2), may be located in refineries, chemical plants, gas plants, exploration and production facilities and supply/marketing depots. This Guide is applicable to all such locations. 1.2 SCOPE Guidance is provided covering the main requirements for the successful d
