Purpose ''This site seeks to promote deeper standardization within the oil and energy industry by highlighting areas where standardization has worked very well and where it has not and why, and provoking discussions on the path forward for better standardization.'' The overall purpose of the document is to issue a guideline on the application of IEC 61508 and IEC 61511 in the Norwegian Petroleum Industry, and thereby simplify the use of the standards. According to the PSA management regulations (§1 and §2), performance requirements shall be established for all safety barriers on an installation. For instrumented safety systems, special reference is made to IEC 61508 and this document as the recommended standard for specification, design and operation of such safety systems. Whereas IEC 61508 describes a fully risk based approach for determining SIL (Safety Integrity Level) requirements, this document provides minimum SIL requirements for the most common instrumented safety functions on a petroleum production installation (ref. chapter 7). Deviations from these requirements may however be identified (ref. section 7.7), and in such case the overall methodology and documentation should be in accordance with IEC 61508. ==Conventional Industry practice== There are still many standards in use within the industry. Shell for example use the IPF method, BP has its own. These standards could be supplements to areas lacking within the standards. Experience shows that the majors tend to go against standards but non adoption of standards tend to lead to unclarity of intention, mistaken interpretations which then leads to costs creep, gold plating and scope. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Standardization in oil industry」の詳細全文を読む スポンサード リンク
