Supplementary Specification to IEC 62271-200 High-voltage switchgear and controlgearForewordThis specification was prepared under a Joint Industry Project 33 (JIP33) “Standardization of EquipmentSpecifications for Procurement” organized by the International Oil & Gas Producers Association (IOGP) withthe support from the World Economic Forum (WEF). Ten key oil and gas companies from the IOGPmembership participated in developing this specification under JIP33 Phase 2 with the objective to leverageand improve industry level standardization for projects globally in the oil and gas sector. The work hasdeveloped a minimized set of supplementary requirements for procurement, with life cycle cost in mind,based on the ten participating members’ company specifications, resulting in a common and jointly approvedspecification, and building on recognized industry and/or international standards.This specification has been developed in consultation with a broad user and supplier base to promote theopportunity to realize benefits from standardization and achieve significant cost reductions for upstreamproject costs. The JIP33 work groups performed their activities in accordance with IOGP’s Competition LawGuidelines (November 2014).Recent trends in oil and gas projects have demonstrated substantial budget and schedule overruns. The Oiland Gas Community within the World Economic Forum (WEF) has implemented a Capital ProjectComplexity (CPC) initiative which seeks to drive a structural reduction in upstream project costs with a focuson industry-wide, non-competitive collaboration and standardization. The vision from the CPC industry is tostandardize specifications for global procurement for equipment and packages, facilitating improvedstandardization of major projects across the globe. While individual oil and gas companies have beenimproving standardization within their own businesses, this has limited value potential and the industry lagsbehind other industries and has eroded value by creating bespoke components in projects.This specification aims to significantly reduce this waste, decrease project costs and improve schedulethrough pre-competitive collaboration on standardization. This document defines the supplementaryrequirements to recognized international standard IEC 62271-200 Edition 2.0 2011, High-voltage switchgearand controlgear, which is indispensable for the application of this specification.Following agreement of the relevant JIP33 work group and approval by the JIP33 Steering Committee, theIOGP Management Committee has agreed to the publication of this specification by IOGP. Where adoptedby the individual operating companies, this specification and associated documentation aims to supersedeexisting company documentation for the purpose of industry-harmonized standardization.Page 1 of 39S-620October 2018
