15、LLATIONS Part 1: General requirements and conditions FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operati

16、on on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “I

17、EC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this prepara

18、tion. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consens

19、us of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are

20、 made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications tra

21、nsparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent

22、 certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liabili

23、ty shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (includi

24、ng legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of th

25、is publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61892-1 has been prepared by IEC technical commi

26、ttee 18: Electrical installations of ships and of mobile and fixed offshore units. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previo

27、us edition. a) The general requirement to harmonic distortion has been changed from IEC 61000-2-4 Class 2 to Class 1. b) The voltage tolerance for a DC system has been changed from 10 % to +10 %, 15 %. c) Annex C (informative) regarding specification of surface treatment and protective painting syst

32、 series of International Standards is intended to enable safety in the design, selection, installation, maintenance and use of electrical equipment for the generation, storage, distribution and utilization of electrical energy for all purposes in offshore units which are used for the purpose of expl

33、oration or exploitation of petroleum resources. This part of the IEC 61892 incorporates and co-ordinates, as far as possible, existing rules and forms a code of interpretation, where applicable, of the requirements of the International Maritime Organization, a guide for future regulations which may

34、be prepared and a statement of practice for offshore unit owners, constructors and appropriate organizations. This standard is based on equipment and practices which are in current use, but it is not intended in any way to impede development of new or improved techniques. The ultimate aim has been t

35、o produce a set of International Standards exclusively for the offshore petroleum industry. BS IEC 61892-1:2015IEC 61892-1:2015 IEC 2015 7 MOBILE AND FIXED OFFSHORE UNITS ELECTRICAL INSTALLATIONS Part 1: General requirements and conditions 1 Scope This part of IEC 61892 contains provisions for elect

36、rical installations in mobile and fixed offshore units including pipeline, pumping or pigging stations, compressor stations and exposed location single buoy moorings, used in the offshore petroleum industry for drilling, processing and storage purposes. This International Standard applies to all ins

37、tallations, whether permanent, temporary, transportable or hand-held, to AC installations up to and including 35 000 V and DC installations up to and including 1 500 V (AC and DC voltages are nominal values). This standard does not apply either to fixed equipment for medical purposes or to the elect

38、rical installations of tankers.
