11、tems and production operations. Some of the information may be useful to experienced electrical maintenance and operating personnel. The intent of the document is to identify important features of offshore electrical systems and to present generally accepted practices for electrical design and insta

12、llation that experience in the offshore petroleum industry has shown results in safe, reliable, efficient, and maintainable operations. Nothing in this RP is to be construed as a fixed rule without regard to sound engineering judgment, nor is it intended to supersede or override any federal, state,

13、or local regulation where applicable.The First Edition of API 14F was published in July 1978 as API 14F, Design and Installation of Electrical Systems for Offshore Production Platforms, under the jurisdiction of the API Production Department. The Second Edition was published on July 1, 1985. The Thi

14、rd Edition was published September 1, 1991. The Fourth Edition was published June 1999, with a new title, Recommended Practice for Design and Installation of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class I, Division 1 and Division 2 Locations. A r

15、elated document, API 14FZ, Recommended Practice for Design and Installation of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class I, Zone 0, Zone 1 and Zone 2 Locations, was published in 1999 to address wiring methods introduced in Article 505 of the 1

16、999 National Electrical Code. This document includes usage of the verbs shall and should; whichever is the more applicable to the function. For the purpose of this document:Shall indicates the RP is considered a minimum requirement that has universal applicability to the specific activity.Should ind

17、icates a RP: (1) for which alternative practices may be equally safe and/or effective; or, (2) which may not be practical under some circumstances or applications.It is recommended indicates a preferred practice that has no known direct safety or regulatory implication.Phrases that use “consider” su

18、ch as “should be considered,” “consideration should be given,” etc, indicate the user should pay particular attention to the referenced topic, in the context of the sentence where used as well as other related topics in this document and then make an application decision based on the relevant facts

19、and sound engineering judgment.This RP shall become effective on the date printed on the cover but may be used voluntarily from the date of distribution.API publications may be used by anyone desiring to do so.
