IEC 61892-1:2019 pdf download.Mobile and fixed offshore units – Electrical installations – Part 1: General requirements and conditions
1 Scope
This part of IEC 61 892 is applicable to electrical installations and equipment in mobile and fixed offshore units, including pipeline, pumping or “pigging” stations, compressor stations and single buoy moorings, used in the offshore petroleum industry for drilling, production, accommodation, processing, storage and offloading purposes. It applies to all installations, whether permanent, temporary, transportable or hand-held, to AC installations and DC installations without any voltage level limitation. Referenced equipment standards may give voltage level limitations.
This document specifies requirements such as those concerning
– environmental conditions,
– power supply characteristics,
– location of electrical equipment in units,
– protection against external influences,
– protection against electrical shock, and
– ignition source control.
This document gives information and guidance on topics such as
– cold climate protection, and
– surface treatment and protective painting system.
This document does not apply to
– fixed equipment for medical purposes,
– electrical installations of tankers, and
– control of ignition sources other than those created by electrical equipment.
NOTE 1 For medical rooms, IEC 60364-7-71 0 provides specific requirements. Requirements for tankers are given in IEC 60092-502.
NOTE 2 Guidance on protection of non-electrical equipment can be found in ISO 80079-36, ISO 80079-37 and IMO 2009 MODU Code, 6.7.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp NOTE The terms and definitions included in this document are those that have general application in the IEC 61 892 series. Terms and definitions applying to particular apparatus or equipment are included in the other parts of the IEC 61 892 series. 3.1 offshore unit construction, buoyant or non-buoyant, designed and built for installation or operation at an offshore location Note 1 to entry: Topside interface of subsea installed equipment which is an integral part of production and transport systems assigned to fixed and floating offshore units, as well as a temporary interface to mobile offshore units, are also considered as part of the offshore unit. 3.2 unmanned offshore unit offshore unit normally unmanned, remote controlled without need of human presence for operability and without living quarter facilities Note 1 to entry: An unmanned offshore unit may also contain a survival shelter to support occasional site maintenance.3.3 fixed offshore unit buoyant or non-buoyant construction engaged in offshore operations including drilling, production, storage or support functions, and which is designed and built for installation at a particular offshore location Note 1 to entry: LNG production units and LNG storage and regasification unit terminals are also considered to be fixed offshore units. FPSO/FSO on location is also considered as a fixed offshore unit. Floating LNG terminals and FPSOs with detachable arrangements are also considered to be fixed offshore units. 3.4 mobile offshore unit buoyant construction engaged in offshore operations including drilling, production, storage, accommodation or support functions, not intended for service at one particular offshore site and which can be relocated without major dismantling or modification, for example barges, semisubmersible or jack-up unit and drill-ships 3.5 manned unit offshore unit with need of human presence for operation and maintenance, and provided with living quarter facility 3.6 satellite unit small offshore unit, normally unmanned, connected to a larger unit by means of a pipeline, power cable and/or umbilical 3.7 appropriate authority governmental body and/or classification society with whose rules a unit is required to comply 3.8 equipment single apparatus or set of devices or apparatuses, or the set of main devices of an installation, or all devices necessary to perform a specific task EXAMPLE Power transformer, measuring equipment.
