IEC 61892-6:2013 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. This edition includes the following significant technical changes with respect to the previous edition.
a) Table 1, size of earth continuity conductors has been replaced with the table in IEC 61892-4.
b) The requirements for installation of batteries has been rewritten in order to distinguish better between batteries of the vented type and VRLA/sealed type.
c) An informative annex regarding cable termination has been added.
d) The applicability for DC installations has been increased from 750 V to 1 500 V, in accordance with Part 1 of the series.
