23、ion (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in

24、addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee int

25、erested 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 preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance

26、 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 consensus of opinion on the relevant subjects since each technical committee has representation from all interest

27、ed 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 made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible

28、 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 transparently to the maximum extent possible in their national and regional publications. Any divergence betw

29、een any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All use

30、rs should ensure that they have the latest edition of this publication. 7) No liability 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 oth

31、er damage of any nature whatsoever, whether direct or indirect, or for costs (including 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.

32、Use of the referenced publications is indispensable for the correct application of this 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 paten

International Standard IEC 61892-4 has been prepared by IEC technical committee 18: Electrical installations of ships and of mobile and fixed offshore units, in cooperation with SC 18A: Cables and cable installations. The text of this standard is based on the following documents: FDIS Repo

34、rt on voting 18/1052/FDIS 18/1058/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 61892-4 IEC:2007(E) 5 A list of all parts of

35、the IEC 61892 series, published under the general title Mobile and fixed offshore units Electrical installations, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site und

A bilingual version of this publication may be issued at a later date. 6 61892-4 IEC:2007(E) INTRODUCTION IEC 61892 for

37、ms a series of International Standards intended to enable safety in the design, selection, installation, maintenance and use of electrical equipment for the generation, storage, distribution and utilisation of electrical energy for all purposes in offshore units which are being used for the purpose

38、of exploration or production of petroleum resources. This part of IEC 61892 also incorporates and coordinates, as far as possible, existing rules and forms a code of interpretation, where applicable, of the requirements of the International Maritime Organisation. It also constitutes a guide for futu

39、re regulations which may be prepared and a statement of practice for offshore unit owners, constructors and appropriate organisations. 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

40、 ultimate aim has been to produce a set of International standards exclusively for the offshore petroleum industry. 61892-4 IEC:2007(E) 7 MOBILE AND FIXED OFFSHORE UNITS ELECTRICAL INSTALLATIONS Part 4: Cables 1 Scope This part of IEC 61892 specifies requirements for the choice and installation of e

41、lectrical cables intended for fixed electrical systems in mobile and fixed offshore units, including pumping or “pigging” stations, compressor stations and exposed location single buoy moorings, used in the offshore petroleum industry for drilling, production, processing and for storage purposes. Th

42、e reference to fixed electrical systems includes those that are subjected to vibration due to the movement of the unit, e.g. cables installed on a drag chain, and not those that are intended for repeated flexing. Cables suitable for repeated flexing use are detailed in other IEC specifications, e.g.

43、 IEC 60227 and IEC 60245, and their uses on board offshore units are restricted to those situations which do not directly involve exposure to a marine environment, e.g. portable tools, domestic appliances, etc. The following types and applications of cables are not included: optical fibre cables; su

44、b-sea and umbilical cables; cables supplying downhole pumps; data, telecommunication and radio frequency cables. 2 Normative references The following referenced documents are indispensable for the application of this document.
