This part of IEC 61892 contains provisions for electrical installation in mobile and fixed offshore units including pipeline, pumping or ‘pigging’ stations, compressor stations and exposed location single buoy moorings, used in the offshore petroleum industry for drilling, processing and for storage purposes.
It applies to all installations, whether permanent, temporary, transportable or hand-held, to AC installations up to and including 35 000 V and DC installations up to and including 1 500 V (AC and DC voltages are nominal values).
This standard does not apply to electrical installations in rooms used for medical purposes, or in tankers.
