This part of IEC 61892 contains provisions for electrical equipment 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.
This standard applies to equipment in all installations, whether permanent, temporary, transportable or hand-held, to a.c. installations up to and including 35 000 V and d.c. installations up to and including 1 500 V (a.c. and d.c. voltages are nominal values).
This standard sets requirements for equipment, which are additional to the requirements given in the product standard for the relevant equipment.
This standard does not apply to the electrical installations in rooms used for medical purposes or in tankers.
