Scope

This document 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 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 system characteristics,

–        location of electrical equipment in units,

–        protection against external performance influencing factors,

–        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 non-electrical ignition sources

NOTE 1 For medical rooms, IEC 60364-7-710 provides specific requirements.

NOTE 2  Requirements for tankers are given in IEC 60092-502.

NOTE 3 Guidance on protection of non-electrical equipment can be found in ISO 80079-36, ISO 80079-37 and IMO 2009 MODU Code, 6.7.
